The nuclear power sources on remote science missions aren't the same as the ones used in power stations or submarines. They are radioisotope thermoelectric generators. They work by capturing the heat from the passive decay of the radioisotope, not by the neutron stimulated decay. Because of this, they can only output a tiny fraction of the power/weight of nuclear reactors.
Mike mf Panik indeed a battery is a reactor it combines an anode cathode and closed electrical circuit to create a chemical reaction. But there is no active reaction in a RTG, the isotopes release heat no matter what at a constant rate. The vessel does not change this decay in any way. Therefore RTG is not a reactor.
You're right, but I want to point out that fission is very different form decay. Fission happens when a neutron hits an atomic nucleus and splits it into two smaller nuclei, while decay occurs when an unstable atomic nucleus spits out a particle via the weak force. Decay events are always random, while fission events can be controlled via the number of neutrons flying around.
yea and by 2000 we were already suppose to have manned mission to Saturn ! :D but i think it makes sence that people thought so with all the moon landings and etc. they thought technology would advance faster than what we have now.
Marius Snow it's more about economy and political commitment, than technology. With our technology we could do unimaginable right now, if not for lack of finance.
True story... I was a research and development electronic technician in 1970 and my boss was an electrical engineer who told me that he worked for 13 years on a government project making a nuclear airplane. After a couple reactor melt downs they perfected the reactors and engines, met all specifications, and even had the airplane sitting in the research hanger ready to install the engines and take the first test flight. The day of the first test flight and after waiting 13 years, when they showed up for work they were informed the project was cancelled. He told me that he really believed that the plane was still around and ready to fly. The only limit on the flight time was food and water and the sanity of the flight crew.
I had read that the US actually flew a nuclear powered plane but it irradiated everything behind it. Asked an old engineer I knew that worked on stuff like that in Nevada. He laughed and shook his head and said, "That thing was a mess!"
... and you can go see the engines today at the EBR-1 National Historic Landmark about 30 minutes west of Idaho Falls, Idaho. They are massive things, about three stories high. inl.gov/experimental-breeder-reactor-i/
All I had read about was a proposal for nuclear powered aircraft, comparing them on an economic basis. The comparison was between a nuclear powered aircraft vs conventional, at masses of 2000 ton and 4000 short tons, and seeing what range would allow for more cargo to be carried cheaper. (As a comparison, the max takeoff weight of a 747 is ~500 short tons, while the AN-225 is ~700 short tons)
Even more indirectly, conventional planet-raping cars burn fossil fuels which store energy from the giant nuclear fusion reactor in sky that reached Earth millions of years ago.
Honeyyyyyy try not to drop the phone or you will wipe us all )))) And yeah.. phone crash test will be only in arizona desert )))) Dbrand promotion: ( spare us for the sake of jesus )))
5000 miles is a pretty unimpressive range considering the complexities of trying to shove a nuclear reactor into a car. Some things were just never that practical. Nuclear powered trains seem like they would still have made some sense. But at scales below that it just seems... A rather questionable use of technology. (and aircraft have weight issues.) Still, even with trains, the idea is rather niche compared to just using an electrified rail network and powering that from nuclear power (or whatever else you may have handy.)
I'm with the trains! That niche is definitely there. I'm thinking "Belt and Road Initiative" territory, developing vast barren areas. You see a lot of this in videos from China about new bridges and railways and highways... they often seem to be in surprisingly blank terrain, where it seems like there's nothing but gravel to the horizon....
Weight issue with planes? The nuclear powerplant, if compact, would be lighter than a heavy load of jet fuel for a long flight. And consider people from low-lying island countries at risk from rising sea-levels due to climate change. Telling those people that a plane that burns normal jet fuel is mor okay than one that burns uranium; is like telling a rape victim that rape is okay, or telling a badly traumatized war veteran (the Iraq War produced plenty of those!) that we should glorify war.
@@justushall9634 It's not the weight of the reactor that is the issue. It's the weight of the shielding. Unless of course you like getting hit with 1000 rems of radiation of course.
A correction: the nuclear power on the Space probes come from nuclear-powered GENERATORS. Not Nuclear REACTORS. They operate off of the decay heat of certain radio-isotopes. Namely Plutonium-238 (though Strontium-90 is a decent secondary candidate). While these things are great for space travel, they are literally just solid-state devices, with a lump of radioactive material decaying and emitting heat, and a bunch of thermocouples harvesting about 1000-2000 watts of thermal energy into about 100 watts of electricity. They are not small nuclear reactors - just generators. They do not use sustained fission chain reactions, and they can never be scaled up to provide the tens, hundreds, or thousands of kilowatts necessary to perform transportation tasks. This is an improper analogy, and your very well made video would be improved if this allusion was removed.
That's absolutely 100%... correct, actually. The only way any space probes past Mars (and recently Jupiter with Juno) have conveyed any information to Earth is through antennae powered by RTGs. The overall SNR you can from a transmitted signal is a function of both the transmission power and receiver power - so with large enough antennae arrays on Earth, and straight empty space from here all the way to Pluto, we can pick up these signals. Communications engineering is a really interesting subset of electrical engineering. But I'm not quite sure I understand what point you wanted to make here. My comment was on the lack of scale-ability for RTG - it's a very reliable, inefficient, low-power method that generates a lot of waste heat (good for keeping computers warm enough to function) and a little bit of power (enough to run small computer, camera, a few instruments, and an antennae - often not all at once). Can you clarify what exactly you wanted to discuss here? To clarify on my end - my insistence on needing kilowatts or megawatts of power refers to running ion engines of any appreciable amount in order to transport larger ships. (Or to power a ship with a human crew, growing food, recycling oxygen, etc.) Ion drives work by accelerating gas to speeds hundreds or thousands of times faster than rocket fuel propellant would leave. Which is great - you can get a lot more push off of the same propellant mass. But moment exchange is (mv) - mass and velocity are directly related, while kinetic energy is (1/2mv^2). So if I want to double my momentum gained from ejecting a kilogram of propellant, I need to double the ejection velocity, and thus I'll double my delta-v. But to double the velocity, I have to put in 4x as much energy. Very quickly, ion engines start to have very large power budgets, and a few dozen or hundred Watts from an RTG just won't be up to the task. Micro-adjustments for deep space satellites - perhaps. But nothing that would involve large probes or human transportation. Anyway, an RTG just can't be scaled up to create kilowatts or Megawatts of electricity. It just becomes impractical. You need a full nuclear reactor, that is producing energy from fission events - not regular nuclear decay.
Actually, electricity in nuclear plants comes from a generator too. The generator is basically a set of big magnets spun by a turbine driven by steam heated by the nuclear reactor itself. What's used in spacecraft is called a Radiothermal Generator or RTG, and while it also uses heat said heat is from decay not fission, and the way its converted into electricity is more technical.
Seems like people in the 40s and 50s viewed nuclear power the way we view IoT - most people think everything is better when connected, no downsides at all.
I always enjoy Curious Droid's well-researched videos. I must object to this video stating that US space probes use nuclear reactors, as those are not nuclear reactors. Thermoelectric generators are not able to be throttled and are fairly low powered (considering that the thermoelectric effect is not efficient).
So, a photoelectric button battery would get categorized as a nuclear reactor, simply because it includes plutonium? What if it contained enriched uranium, instead? The difference between a reactor and an RTG is that a reactor operates based on sustaining an atomic chain reaction (hence, reactor), but an RTG operates by the natural decay of radioactive materials (hence, not a reaction and so not a reactor).
Richard Alexander Nailed it Rick. I was thinking the same thing when he basically said RTG's were nuclear reactors. Now I don't have to post an explanation myself. Thank you. :)
The research he found was most likely information on the blueprints of the train which of course were American so it was in imperial units. Brits are also pretty familiar with it. Just going to have to research it yourself.
Man... This is so odd... I feel so bad that such a great content channel like this would feel that way about international users: "Just going to have to research it yourself." Hope he listens and try to help us (non british / non american followers) to better understand the measures.
Vitor Madeira Why do you feel bad? Do you know how much of an ass you sound like? It's just one example in one video, who cares. It doesn't effect you at all, we can move on...
Why not let the author deal with the situation? Please, forget my question here. It was not intended for you. if you don't like it, don't answer. Thank you.
Vitor Madeira More than just Americans and British understand these units. Think of every 1 metre as 3 foot for a general idea. Us non metric users do this when exact measures aren't needed.
Two could-have-been's not mentioned: Project Pluto, a nuclear-powered, nuclear armed cruise missile that used a nuclear ramjet engine, would fly at over Mach 3, at very low level. So low in fact that the shockwave from its passing would kill or cripple anyone directly under it - which would have been a mercy, as it would've been spewing lethal levels of gamma radiation behind it. It would be armed with 15 one megaton nuclear bombs that it would use TERCOM and astro-navigation to fly to targets and deploy. Then, once all fifteen warheads were ejected, it would find a final target, shut down the oxygen flow over the reactor, and circle the target slowly. The reactor, now no longer receiving cooling air blasting over it, would melt down. Molten plutonium would literally rain out over wherever the missile was circling, until it ran out of airspeed and crashed creating a permanently uninhabitable crash-site. The other was equally as horrifying _seeming_ but actually quite neat. The Orion project would've used nuclear bombs for propulsion in deep space. By ejecting a nuclear explosive out of the back of a spacecraft shielded by essentially a large "plate", the spacecraft would've been propelled by the oomph of the bombs going off behind it, eventually pushing it to tens of thousands of miles an hour.
A low-flying Pluto wouldn't kill people from the shock wave, it would kill them by bombarding them with neutrons from the unshielded reactor. Also, one idea for Project Orion was indeed horrifying: it was to use it as a gigantic nuclear missile which would lob a humongous hydrogen bomb high over the USSR whose blast of light and radiation would basically fry a whole continent from space. Closest thing to a Death Star we ever dreamed up, and scared the crap out of President Kennedy and the Orion engineers who just wanted to explore the Solar System.

Last year I was on a trip to see the 2017 eclipse, taking a road trip to the western US. One of the places we stopped was EBR-1, one of the first-ever nuclear power plants. Outside, they actually have two hulking constructs filled with pipes and scaffolds and a large central cask. These are actually testing armatures to mount a nuclear reactor and several J-43 engines with fuel systems converted to use, rather than combustion, nuclear energy as heat to sustain jet thrust. The whole construct was on rails that ran along the desert wastelands that served as the testbeds for America's burgeoning military in the early Atomic Age. It really seemed a shame that we lack planes or trains that run on nuclear. Shame it seems it would never really work.
Daniel Thompson not if it's done smart, it would be great in airplanes, buses, heavy construction equipment and even trains but I agree small cars should just run on electricity because they don't need much torque.
So what happens when that plane crashes? An accident that involves release of nuclear material in a stationary MSR is more or less inconceivable, but put it in a plane and the risk is non zero.
Daniel Thompson with todays technology we could put designs into test in modern computers, that way you would know the best way to construct a very safe nuclear reactor for planes.
Firstly flying is inherently risky. You can make it very safe but never 100% safe. Secondly there is no need for it, we don't need planes that fly for weeks at a time these days.
I never said there's need for it, neither that it would be 100% safe. What I said is that it can be done and it could be safe, would it be worth it? I don't think so
Great video, but a few comments: Spacecraft do not use _nuclear_ (fission)power plants to generate electricity, but _radiological_ ones that rely on alpha or beta decay. There have been a few test reactors flown in space, but all practical spacecraft either use RTGs or solar. I was also a little disappointed you didn't mention the type of nuclear reactors tested for Aircraft Reactor Experiment. At least in the US, the reactor tested was a _molten salt reactor_ that used liquid fuel. All the other reactors mentioned here (I believe) used solid fuel elements and either water or sodium metal for cooling. But the aircraft reactor, because the fuel was dissolved in a molten salt, could operate at higher temperatures (and thus higher efficiency), low pressure (and thus less deadweight), and, in a land-based power plant, be practically meltdown-proof because the fuel was already fluid and not solid uranium or uranium oxide. Building on the Aircraft Reactor Experiment, the scientists at ORNL ran the Molten Salt Reactor Experiment from '65 to '69 with great success, and this design forms the basis for one of the Gen-IV reactor types proposed in 2002 and are in active development today. Cheers! :D
Pyre Vulimorph; he correctly stated that the reactor proposed for the X-12 nuclear locomotive also used a liquid fuel; name weapons grade uranium in a sulfuric acid "soup." Refueling the reactor would have consisted of replacing the soup mixture; the old mixture would have the waste products removed so it could be used again.
5:36 NBC's SuperTrain? (It was supposed to be 'The Love Boat' on rails) The scale model wrecked during shooting. Would have made a nice Disaster of the Week movie. ALSO...Did you remember the nuclear vehicle from 'The Big Bus'?
Let's not forget the 1960's bat mobile. Robin was quoted as saying ATOMIC BATTERIES to power turbines to speed ready to move out. Then batman would say roger. So the batmobile was powered by atomic batteries. What ever the heck that is.
The novel on which the movie 'When World's Collide' was based had a sequel. On the now defrosted planet they discovered mostly intact advanced alien technology which included rechargeable automobiles. In a manner not explained by the author the batteries combined radioactivity and electricity. Written in the 1930s they had no idea how atomic energy would work.
A real life "atomic battery" is a radioisotopic thermoelectric generator, or RTG, like the ones flown on space probes. They are basically a thermocouple wrapped around a substance like plutonium or strontium 90 which generates heat from decay. The whole thing is encased in shielding to survive a launch failure and is quote safe to handle if built right, but not very efficient for the weight. So they are good for powering a space probe's electronics, but to power an electric car they'd be kind of weak and heavy.
In a 1960s encyclopedia (The annual update?) they had a radioisotope, a phosphor and a photovotaic cell act as a battery for low power applications. Must not have panned out. The radiation degrades the PV cell?
It just seems if we are going to do the nuclear route, it needs to be in the form of safer, more efficient stationary designs such as LFTR reactors on Earth and advanced nuclear reactors in space. What we have done in space so far isn't more advanced, but instead throw some radioactive waste into a bottle and get a small amount of heat off of it as it decays. So if you really look long and hard at nuclear power on Earth we get something like the following: 1. Airplanes - Sounds nice, but don't need it and bound to cause a lot more problems than it solves unless of course your goal is exposure to the horrors of nuclear fallout. 2. Cars - Yeah, every major crash, which there are piles of every year, is a nuclear disaster. We might end up with a nuclear winter with all of the catastrophic accidents and poorly maintained vehicles, especially if light water reactors are used. 3. Trains - You really don't want to be around that derailed freight train carrying hazardous materials being pulled by nuclear powered locomotives. Talk about a train wreck... 4. Ships - Away from military use, there comes the question of how much are you going to spend on that security detail and what happens if you don't? Also are we ever going to get commercial freighters into the modern age? I suppose at least huge sums are spent on fueling giant ships, so it seems a bit more plausible the security and precautions around nuclear may be weighed to see if it is the cheaper option. If we look long and hard at Nuclear in space, we get something like the following: 1. Space is already full of radiation. Your space ship in deep space is spewing out radiation in an already radiation filled solar system? Does it really matter? 2. The inner solar system has lots of light to work with, but gets a lot weaker the further you get out. 3. Most places you go in the solar system, the Sun always shines, just at different intensities with the distance. 4. Much of the solar system of potential interest there is not a very good light resource. 5. If we really want to get a more useful thrust out of ion drives, especially in the farther reaches of the solar system, it helps to have a powerful and lightweight nuclear reactor. 6. If we want more efficient engines in space, nuclear does tend to provide more kick. 7. A Lunar base in shadow for a couple of weeks at a time could really use something like Nuclear power. If a nuclear reactor melted down on Luna, it is like at least there is no other life here and no atmosphere or anything. The material just stays in place until we scoop it up and put it in a sealed container. 8. A Mars base, especially during a dust storm, could really use something like nuclear power. Also as Mars tends to be a lot colder than Earth, the warmth from a nuclear reactor could be nice. On Mars you want to be a little more careful than say Luna as the wind can blow radioactive particles around, however at least at present we consider Mars to be a pretty dead place, so the damage possible is a lot more limited. 9. As Mars doesn't seem to have much of a resource for chemical energy like Earth does, the idea of nuclear for some form of transit may be revisited. Maybe a large land ship or something going long distances around Mars? The idea being nuclear will probably be the only practical way to do certain tasks on Mars, but maybe you could find a solution that works reasonably well under the circumstances. In summary it seems there are not many places where you could really justify using nuclear over other means on Earth. This is as in we have something that already works and nuclear is just way to problematic in way too many ways to be a reasonable solution. So if you want to do it better, maybe look at other technologies to get the job done or at least fine tune / enhance the existing ones. However in space while there are a number of places where solar power seems like a great option, there are also a lot of places and a lot of cases where it is nuclear or bust, plus the concerns we have here on Earth are not so much of a concern elsewhere in the solar system.

The super train actually makes sense with Russia I'm surprised the Soviets didn't at least do a conventionally powered supersized train just for their space program as transporting parts via barges was not an option.
IMO the biggest applications for nuclear technology should be terrestrial power generation and space travel. We already have one of these, and the US has successfully tested a nuclear thermal rocket engine.
Excellent video. I highly recommend anybody traveling the US to make a stop at EBR-1, the Experimental Breeder Reactor 1, in central Idaho. On display outside are the two atomic jet test beds, as well as the heavily shielded locomotive that would be assigned to move the bomber to and from its ginormous hangar (which was actually built, and still exists).
Dear author! Ту-96ЛАЛ (for "flying atomic lab") newer had direct cycle nuclear jet engines, it only had an idle reactor in its bomb bay. The only reason of existing Ту-96ЛАЛ was to test the shielding, so when you say "it had no shielding" you're utterly wrong. The plane had shielding, both lead and composite, both for crew compartment and around reactor itself. Fancy shirt does not substitutes elementary fact-checking.
Even if you could engineer against accidents and radiation... I still wouldn't want this tech anywhere other than secure locations. How easy would it be for someone to hijack a nuclear train and steal the cores?
Well you can sort of, 4th gen nuclear reactors are unlikely to go critical. As for security I agree. It is a terrifying thought that somebody thinks it is a good idea to build nuclear powered drones which have a track record of being hacked.
Nearly impossible without being willing to die! The second you turn off a nuclear reactor it is still extremely radioactive and will be for months. Even after that you will still need protective gear and to remove lots of shielding and permanent seals.
To think - that using 1960's technology, the Soviets actually had planes flying powered by NUCLEAR reactors... I think (if humanity survives the 21st Century) that nuclear power will be the greatest "why didn't we use this earlier" technology in human history.
I think you are wrong. Nuclear power is like stone age tech compared to what is to come. It would be like saying "huh remember the good ol days when it rained coal on london and the sun never reached the ground, people as white as snow ..(if you washed their faces) for they had never seen the sun".. yea good ol days. Nuclear reactors are by far the most expensive way to produce electricity from all the established technologies we have. It also consumes fuel just like coal and gas.. its not sustainable, its dangerous , unreliable, very expensive and it takes ages to build a reactor. its ridiculously stupid to build new nuclear reactors which is why almost nobody is doing it anymore, the costs are just too high. Also it pollutes the air more than coal does due to the Co² from mining and transporting the nuclear stuff and from disposing it.. apparently its more complicated to fuel a reactor than a coal plant.. Coal though is becoming old timey too and plays a exceedingly lower role in my country, germany.
T.W. Someone I mean Nuclear power safer in a lot of cases, plus most accidents involving Nuclear stations were either human error (Chernobyl) or due to many things happening at once (fukishima)
The thing is nuclear is just an unecessary high risk, imagine one war between a nation with nuclear reactors and they get targeted and destroyed. It would affect the whole world immensely and that country and many other areas would be unusable for thousands of years. Chernobyl forced everyone to check all sorts of places for radioactivity, some forests or fields had dangerous levels of radioactivity for anyone who would eat anything out of them. Its not dissapearing fast either. That one "little" human error (those happen all the time!) created a damage that surely on long term was far more expensive to everyone than what thousands of reactors would have saved of money back in the day when other types of electricity weren't widely spread.
T.W. Someone Chernobyl is a great reminder of what not to do, the fail safe for one of the reactors were purposely disabled for testing, Plus the Chernobyl Nuclear powerplant used a flawed Soviet reactor design which helped cause the disaster
Actually, nuclear power is the least expensive source of electricity. Imagine if all the third world nations had access to cheap electricity. Poverty would be eradicated, which doesn't seem to be the plan.
How would you get the reactor to power an airplane? A battery bank? You would need a big ole bessy stack of lithium batteries for a purely battery powered airplane. Everything else? Sure!
@@patdohrety2940 lithium ion technology as far as batteries go, is approaching 20 years old now. They can fit the same power density in a film, that has semi flexibility and these are being tested for powering aircraft. Of course the number of aircraft is quite limited, yet it is actually being flight tested. For a reactor to power an aircraft, admittedly: you're talking about using several state of the art technologies. Back in the 60's, they actually tried installing the nuclear reactor into an aircraft, and using the heat to power a set of turbines that powered the aircraft. For reasons obvious, this is simply crazy in my opinion. 😳😂😂 Take care.

Thorium is not safer than uranium or plutonium based reactors. In fact, thorium is used to breed u233. What's safer are the types of reactors people are wanting to use thorium in.
the train at 4:30 - also one thing most people (and me up until a few days ago) don't think of, is maintaining vehicles like that. any locomotive with an unpowered tender etc is rely hard to maintain, becuse workers cant move them around by themselves in a workshop, they will need to bring a shunter in, which hasn't been needed since the steam era. a few years ago railway companies started experimenting with gas (as in natural gas, LPG gas, not petroleum) locomotives, but these needed large tenders to house the gas, as there wasn't enough room on board the loco (gas takes up more space than liquid fuel). the 2 main reasons this project failed was 1) Diesel fuel prices dropped significantly while the project was going on, and 2) most railway companies no longer had the ability to move around unpowered loco tenders any-more. good for the environment and the future, bad for having to buy newer equipment.
In case I didn't already comment on it...space probes do not use miniature reactors. They use RTG's which are essentially to heat what a solar cell is to light. The decay heat from a small amount of plutonium (or another element) is directly converted to electrical power.
The only problem is nuclear shielding. You can't have 10-20 feet thick lead walls around the reactor. Gotta figure another way out of this radiation problem
The US nuclear powered bomber was designed around the ARE ( airborn reactor experiment). It ran on liquid salt cooled, Thorium fuelled reactor that was built and ran for hours without issues. Another notable mention is Project Pluto which was a sold uranium fuelled direct cycle cruise missile scramjet( no shielding needed) which was very large. Its engine was tested as both a scale prototype and full size prototype and performed perfectly.
They made a TV show about a super-wide nuclear powered train traveling around the US. It was called Supertrain! The show was really bad but the model they used for exterior shots of the train was vary cool.

Mike mf Panik indeed a battery is a reactor it combines an anode cathode and closed electrical circuit to create a chemical reaction.

You're right, but I want to point out that fission is very different form decay. Fission happens when a neutron hits an atomic nucleus and splits it into two smaller nuclei, while decay occurs when an unstable atomic nucleus spits out a particle via the weak force. Decay events are always random, while fission events can be controlled via the number of neutrons flying around.

Even more indirectly, conventional planet-raping cars burn fossil fuels which store energy from the giant nuclear fusion reactor in sky that reached Earth millions of years ago.

@@jimboonie9885 Why?
5000 miles is a pretty unimpressive range considering the complexities of trying to shove a nuclear reactor into a car.
Some things were just never that practical.
Nuclear powered trains seem like they would still have made some sense. But at scales below that it just seems... A rather questionable use of technology.
(and aircraft have weight issues.)
Still, even with trains, the idea is rather niche compared to just using an electrified rail network and powering that from nuclear power (or whatever else you may have handy.)
I'm with the trains! That niche is definitely there. I'm thinking "Belt and Road Initiative" territory, developing vast barren areas. You see a lot of this in videos from China about new bridges and railways and highways... they often seem to be in surprisingly blank terrain, where it seems like there's nothing but gravel to the horizon....
What about boats? Some already are 100% nuclear powered
Weight issue with planes? The nuclear powerplant, if compact, would be lighter than a heavy load of jet fuel for a long flight. And consider people from low-lying island countries at risk from rising sea-levels due to climate change. Telling those people that a plane that burns normal jet fuel is mor okay than one that burns uranium; is like telling a rape victim that rape is okay, or telling a badly traumatized war veteran (the Iraq War produced plenty of those!) that we should glorify war.
@@justushall9634 It's not the weight of the reactor that is the issue. It's the weight of the shielding. Unless of course you like getting hit with 1000 rems of radiation of course.
This was the 50s. First gen nuclear reactor didnt harvest a lot of energy per gram of fissile Material as newer reactors do
A correction: the nuclear power on the Space probes come from nuclear-powered GENERATORS. Not Nuclear REACTORS.
They operate off of the decay heat of certain radio-isotopes. Namely Plutonium-238 (though Strontium-90 is a decent secondary candidate).
While these things are great for space travel, they are literally just solid-state devices, with a lump of radioactive material decaying and emitting heat, and a bunch of thermocouples harvesting about 1000-2000 watts of thermal energy into about 100 watts of electricity.
They are not small nuclear reactors - just generators. They do not use sustained fission chain reactions, and they can never be scaled up to provide the tens, hundreds, or thousands of kilowatts necessary to perform transportation tasks. This is an improper analogy, and your very well made video would be improved if this allusion was removed.
Well said. Thank you for bringing this to light.
That's absolutely 100%... correct, actually.
The only way any space probes past Mars (and recently Jupiter with Juno) have conveyed any information to Earth is through antennae powered by RTGs. The overall SNR you can from a transmitted signal is a function of both the transmission power and receiver power - so with large enough antennae arrays on Earth, and straight empty space from here all the way to Pluto, we can pick up these signals.
Communications engineering is a really interesting subset of electrical engineering. But I'm not quite sure I understand what point you wanted to make here. My comment was on the lack of scale-ability for RTG - it's a very reliable, inefficient, low-power method that generates a lot of waste heat (good for keeping computers warm enough to function) and a little bit of power (enough to run small computer, camera, a few instruments, and an antennae - often not all at once). Can you clarify what exactly you wanted to discuss here?
To clarify on my end - my insistence on needing kilowatts or megawatts of power refers to running ion engines of any appreciable amount in order to transport larger ships. (Or to power a ship with a human crew, growing food, recycling oxygen, etc.) Ion drives work by accelerating gas to speeds hundreds or thousands of times faster than rocket fuel propellant would leave. Which is great - you can get a lot more push off of the same propellant mass.
But moment exchange is (mv) - mass and velocity are directly related, while kinetic energy is (1/2mv^2). So if I want to double my momentum gained from ejecting a kilogram of propellant, I need to double the ejection velocity, and thus I'll double my delta-v. But to double the velocity, I have to put in 4x as much energy. Very quickly, ion engines start to have very large power budgets, and a few dozen or hundred Watts from an RTG just won't be up to the task. Micro-adjustments for deep space satellites - perhaps. But nothing that would involve large probes or human transportation.
Anyway, an RTG just can't be scaled up to create kilowatts or Megawatts of electricity. It just becomes impractical. You need a full nuclear reactor, that is producing energy from fission events - not regular nuclear decay.
Actually, electricity in nuclear plants comes from a generator too. The generator is basically a set of big magnets spun by a turbine driven by steam heated by the nuclear reactor itself.
What's used in spacecraft is called a Radiothermal Generator or RTG, and while it also uses heat said heat is from decay not fission, and the way its converted into electricity is more technical.

I always enjoy Curious Droid's well-researched videos.
I must object to this video stating that US space probes use nuclear reactors, as those are not nuclear reactors. Thermoelectric generators are not able to be throttled and are fairly low powered (considering that the thermoelectric effect is not efficient).
RTGs are classed as nuclear reactors based upon their use of plutonium as a fuel source, not how they generate power.
So, a photoelectric button battery would get categorized as a nuclear reactor, simply because it includes plutonium? What if it contained enriched uranium, instead?
The difference between a reactor and an RTG is that a reactor operates based on sustaining an atomic chain reaction (hence, reactor), but an RTG operates by the natural decay of radioactive materials (hence, not a reaction and so not a reactor).
Richard Alexander Nailed it Rick. I was thinking the same thing when he basically said RTG's were nuclear reactors. Now I don't have to post an explanation myself. Thank you. :)
Yeah... That last sell part of the wonders of future unshielded nuclear transportation was a bit iffy...

Vitor Madeira More than just Americans and British understand these units. Think of every 1 metre as 3 foot for a general idea. Us non metric users do this when exact measures aren't needed.
Two could-have-been's not mentioned: Project Pluto, a nuclear-powered, nuclear armed cruise missile that used a nuclear ramjet engine, would fly at over Mach 3, at very low level. So low in fact that the shockwave from its passing would kill or cripple anyone directly under it - which would have been a mercy, as it would've been spewing lethal levels of gamma radiation behind it. It would be armed with 15 one megaton nuclear bombs that it would use TERCOM and astro-navigation to fly to targets and deploy. Then, once all fifteen warheads were ejected, it would find a final target, shut down the oxygen flow over the reactor, and circle the target slowly. The reactor, now no longer receiving cooling air blasting over it, would melt down. Molten plutonium would literally rain out over wherever the missile was circling, until it ran out of airspeed and crashed creating a permanently uninhabitable crash-site.
The other was equally as horrifying _seeming_ but actually quite neat. The Orion project would've used nuclear bombs for propulsion in deep space. By ejecting a nuclear explosive out of the back of a spacecraft shielded by essentially a large "plate", the spacecraft would've been propelled by the oomph of the bombs going off behind it, eventually pushing it to tens of thousands of miles an hour.
A low-flying Pluto wouldn't kill people from the shock wave, it would kill them by bombarding them with neutrons from the unshielded reactor. Also, one idea for Project Orion was indeed horrifying: it was to use it as a gigantic nuclear missile which would lob a humongous hydrogen bomb high over the USSR whose blast of light and radiation would basically fry a whole continent from space. Closest thing to a Death Star we ever dreamed up, and scared the crap out of President Kennedy and the Orion engineers who just wanted to explore the Solar System.

Last year I was on a trip to see the 2017 eclipse, taking a road trip to the western US. One of the places we stopped was EBR-1, one of the first-ever nuclear power plants. Outside, they actually have two hulking constructs filled with pipes and scaffolds and a large central cask. These are actually testing armatures to mount a nuclear reactor and several J-43 engines with fuel systems converted to use, rather than combustion, nuclear energy as heat to sustain jet thrust.
The whole construct was on rails that ran along the desert wastelands that served as the testbeds for America's burgeoning military in the early Atomic Age. It really seemed a shame that we lack planes or trains that run on nuclear. Shame it seems it would never really work.

I'm a big fan of next gen nuclear power but the idea of using it directly in transportation is just stupid.
Daniel Thompson not if it's done smart, it would be great in airplanes, buses, heavy construction equipment and even trains but I agree small cars should just run on electricity because they don't need much torque.
So what happens when that plane crashes? An accident that involves release of nuclear material in a stationary MSR is more or less inconceivable, but put it in a plane and the risk is non zero.
Daniel Thompson with todays technology we could put designs into test in modern computers, that way you would know the best way to construct a very safe nuclear reactor for planes.
Firstly flying is inherently risky. You can make it very safe but never 100% safe. Secondly there is no need for it, we don't need planes that fly for weeks at a time these days.
I never said there's need for it, neither that it would be 100% safe. What I said is that it can be done and it could be safe, would it be worth it? I don't think so
Great video, but a few comments: Spacecraft do not use _nuclear_ (fission)power plants to generate electricity, but _radiological_ ones that rely on alpha or beta decay. There have been a few test reactors flown in space, but all practical spacecraft either use RTGs or solar.
I was also a little disappointed you didn't mention the type of nuclear reactors tested for Aircraft Reactor Experiment. At least in the US, the reactor tested was a _molten salt reactor_ that used liquid fuel. All the other reactors mentioned here (I believe) used solid fuel elements and either water or sodium metal for cooling. But the aircraft reactor, because the fuel was dissolved in a molten salt, could operate at higher temperatures (and thus higher efficiency), low pressure (and thus less deadweight), and, in a land-based power plant, be practically meltdown-proof because the fuel was already fluid and not solid uranium or uranium oxide.
Building on the Aircraft Reactor Experiment, the scientists at ORNL ran the Molten Salt Reactor Experiment from '65 to '69 with great success, and this design forms the basis for one of the Gen-IV reactor types proposed in 2002 and are in active development today.
Cheers! :D
Pyre Vulimorph; he correctly stated that the reactor proposed for the X-12 nuclear locomotive also used a liquid fuel; name weapons grade uranium in a sulfuric acid "soup." Refueling the reactor would have consisted of replacing the soup mixture; the old mixture would have the waste products removed so it could be used again.
This again. Soviets flew fission reactors to space and even dropped one on Canada.

5:36 NBC's SuperTrain? (It was supposed to be 'The Love Boat' on rails) The scale model wrecked during shooting. Would have made a nice Disaster of the Week movie. ALSO...Did you remember the nuclear vehicle from 'The Big Bus'?
Let's not forget the 1960's bat mobile. Robin was quoted as saying ATOMIC BATTERIES to power turbines to speed ready to move out. Then batman would say roger. So the batmobile was powered by atomic batteries. What ever the heck that is.
The novel on which the movie 'When World's Collide' was based had a sequel. On the now defrosted planet they discovered mostly intact advanced alien technology which included rechargeable automobiles. In a manner not explained by the author the batteries combined radioactivity and electricity. Written in the 1930s they had no idea how atomic energy would work.
A real life "atomic battery" is a radioisotopic thermoelectric generator, or RTG, like the ones flown on space probes. They are basically a thermocouple wrapped around a substance like plutonium or strontium 90 which generates heat from decay. The whole thing is encased in shielding to survive a launch failure and is quote safe to handle if built right, but not very efficient for the weight. So they are good for powering a space probe's electronics, but to power an electric car they'd be kind of weak and heavy.
In a 1960s encyclopedia (The annual update?) they had a radioisotope, a phosphor and a photovotaic cell act as a battery for low power applications.
Must not have panned out.
The radiation degrades the PV cell?
The Big Bus: The greatest, most under-rated movie of all time... Hollywood is probably getting to remake it...
Wow, I had not heard about any of this. Thanks for another great article. Keep them coming!
I’m still waiting for the narrator to say,
“Outstanding move”
It just seems if we are going to do the nuclear route, it needs to be in the form of safer, more efficient stationary designs such as LFTR reactors on Earth and advanced nuclear reactors in space. What we have done in space so far isn't more advanced, but instead throw some radioactive waste into a bottle and get a small amount of heat off of it as it decays.
So if you really look long and hard at nuclear power on Earth we get something like the following:
1. Airplanes - Sounds nice, but don't need it and bound to cause a lot more problems than it solves unless of course your goal is exposure to the horrors of nuclear fallout.
2. Cars - Yeah, every major crash, which there are piles of every year, is a nuclear disaster. We might end up with a nuclear winter with all of the catastrophic accidents and poorly maintained vehicles, especially if light water reactors are used.
3. Trains - You really don't want to be around that derailed freight train carrying hazardous materials being pulled by nuclear powered locomotives. Talk about a train wreck...
4. Ships - Away from military use, there comes the question of how much are you going to spend on that security detail and what happens if you don't? Also are we ever going to get commercial freighters into the modern age? I suppose at least huge sums are spent on fueling giant ships, so it seems a bit more plausible the security and precautions around nuclear may be weighed to see if it is the cheaper option.
If we look long and hard at Nuclear in space, we get something like the following:
1. Space is already full of radiation. Your space ship in deep space is spewing out radiation in an already radiation filled solar system? Does it really matter?
2. The inner solar system has lots of light to work with, but gets a lot weaker the further you get out.
3. Most places you go in the solar system, the Sun always shines, just at different intensities with the distance.
4. Much of the solar system of potential interest there is not a very good light resource.
5. If we really want to get a more useful thrust out of ion drives, especially in the farther reaches of the solar system, it helps to have a powerful and lightweight nuclear reactor.
6. If we want more efficient engines in space, nuclear does tend to provide more kick.
7. A Lunar base in shadow for a couple of weeks at a time could really use something like Nuclear power. If a nuclear reactor melted down on Luna, it is like at least there is no other life here and no atmosphere or anything. The material just stays in place until we scoop it up and put it in a sealed container.
8. A Mars base, especially during a dust storm, could really use something like nuclear power. Also as Mars tends to be a lot colder than Earth, the warmth from a nuclear reactor could be nice. On Mars you want to be a little more careful than say Luna as the wind can blow radioactive particles around, however at least at present we consider Mars to be a pretty dead place, so the damage possible is a lot more limited.
9. As Mars doesn't seem to have much of a resource for chemical energy like Earth does, the idea of nuclear for some form of transit may be revisited. Maybe a large land ship or something going long distances around Mars? The idea being nuclear will probably be the only practical way to do certain tasks on Mars, but maybe you could find a solution that works reasonably well under the circumstances.
In summary it seems there are not many places where you could really justify using nuclear over other means on Earth. This is as in we have something that already works and nuclear is just way to problematic in way too many ways to be a reasonable solution. So if you want to do it better, maybe look at other technologies to get the job done or at least fine tune / enhance the existing ones. However in space while there are a number of places where solar power seems like a great option, there are also a lot of places and a lot of cases where it is nuclear or bust, plus the concerns we have here on Earth are not so much of a concern elsewhere in the solar system.

Even if you could engineer against accidents and radiation... I still wouldn't want this tech anywhere other than secure locations. How easy would it be for someone to hijack a nuclear train and steal the cores?
abz998 not very since there'd be a lot of security
Well you can sort of, 4th gen nuclear reactors are unlikely to go critical. As for security I agree. It is a terrifying thought that somebody thinks it is a good idea to build nuclear powered drones which have a track record of being hacked.
Draco Lithfiend yeh I agree but i think it would be better to have a driver so it couldn't be hacked and security near the reactor
Nearly impossible without being willing to die! The second you turn off a nuclear reactor it is still extremely radioactive and will be for months. Even after that you will still need protective gear and to remove lots of shielding and permanent seals.
are you trying to imply the core could be turned into a bomb?
Another great, smart video. Always hearty food for thought and inspiring further reading. Thanks!!!
To think - that using 1960's technology, the Soviets actually had planes flying powered by NUCLEAR reactors... I think (if humanity survives the 21st Century) that nuclear power will be the greatest "why didn't we use this earlier" technology in human history.
I think you are wrong. Nuclear power is like stone age tech compared to what is to come. It would be like saying "huh remember the good ol days when it rained coal on london and the sun never reached the ground, people as white as snow ..(if you washed their faces) for they had never seen the sun".. yea good ol days. Nuclear reactors are by far the most expensive way to produce electricity from all the established technologies we have. It also consumes fuel just like coal and gas.. its not sustainable, its dangerous , unreliable, very expensive and it takes ages to build a reactor. its ridiculously stupid to build new nuclear reactors which is why almost nobody is doing it anymore, the costs are just too high. Also it pollutes the air more than coal does due to the Co² from mining and transporting the nuclear stuff and from disposing it.. apparently its more complicated to fuel a reactor than a coal plant.. Coal though is becoming old timey too and plays a exceedingly lower role in my country, germany.
T.W. Someone I mean Nuclear power safer in a lot of cases, plus most accidents involving Nuclear stations were either human error (Chernobyl) or due to many things happening at once (fukishima)
The thing is nuclear is just an unecessary high risk, imagine one war between a nation with nuclear reactors and they get targeted and destroyed. It would affect the whole world immensely and that country and many other areas would be unusable for thousands of years. Chernobyl forced everyone to check all sorts of places for radioactivity, some forests or fields had dangerous levels of radioactivity for anyone who would eat anything out of them. Its not dissapearing fast either. That one "little" human error (those happen all the time!) created a damage that surely on long term was far more expensive to everyone than what thousands of reactors would have saved of money back in the day when other types of electricity weren't widely spread.
T.W. Someone Chernobyl is a great reminder of what not to do, the fail safe for one of the reactors were purposely disabled for testing, Plus the Chernobyl Nuclear powerplant used a flawed Soviet reactor design which helped cause the disaster
Actually, nuclear power is the least expensive source of electricity. Imagine if all the third world nations had access to cheap electricity. Poverty would be eradicated, which doesn't seem to be the plan.
Great explanation and research as always. Thanks!

How would you get the reactor to power an airplane? A battery bank? You would need a big ole bessy stack of lithium batteries for a purely battery powered airplane. Everything else? Sure!
@@patdohrety2940 lithium ion technology as far as batteries go, is approaching 20 years old now.
They can fit the same power density in a film, that has semi flexibility and these are being tested for powering aircraft. Of course the number of aircraft is quite limited, yet it is actually being flight tested.
For a reactor to power an aircraft, admittedly: you're talking about using several state of the art technologies. Back in the 60's, they actually tried installing the nuclear reactor into an aircraft, and using the heat to power a set of turbines that powered the aircraft. For reasons obvious, this is simply crazy in my opinion.

Thorium is not safer than uranium or plutonium based reactors. In fact, thorium is used to breed u233. What's safer are the types of reactors people are wanting to use thorium in.
the train at 4:30 - also one thing most people (and me up until a few days ago) don't think of, is maintaining vehicles like that. any locomotive with an unpowered tender etc is rely hard to maintain, becuse workers cant move them around by themselves in a workshop, they will need to bring a shunter in, which hasn't been needed since the steam era. a few years ago railway companies started experimenting with gas (as in natural gas, LPG gas, not petroleum) locomotives, but these needed large tenders to house the gas, as there wasn't enough room on board the loco (gas takes up more space than liquid fuel). the 2 main reasons this project failed was 1) Diesel fuel prices dropped significantly while the project was going on, and 2) most railway companies no longer had the ability to move around unpowered loco tenders any-more.
good for the environment and the future, bad for having to buy newer equipment.
6:57 the real chem trails
how do you make such amazing videos, mate? too good. too good.
People can barely Drive regular cars probably not a good idea given them a nuclear powered car
The Germans can drive. I go over there every year just to experience proper driving.
In case I didn't already comment on it...space probes do not use miniature reactors. They use RTG's which are essentially to heat what a solar cell is to light. The decay heat from a small amount of plutonium (or another element) is directly converted to electrical power.
The only problem is nuclear shielding. You can't have 10-20 feet thick lead walls around the reactor. Gotta figure another way out of this radiation problem
That's where 4th generation nuclear energy comes in
Esse canal é muito bom. Temos poucos canais como esse aqui no Brasil.
so there's a chance where everything is just Chernobyl?
The US nuclear powered bomber was designed around the ARE ( airborn reactor experiment). It ran on liquid salt cooled, Thorium fuelled reactor that was built and ran for hours without issues. Another notable mention is Project Pluto which was a sold uranium fuelled direct cycle cruise missile scramjet( no shielding needed) which was very large. Its engine was tested as both a scale prototype and full size prototype and performed perfectly.
Fallout, anyone...?
Kevin Morales yup
great presentation... i have to say... really enjoyable
until nuclear fusion is realty nuclear powered cars are not practical
They made a TV show about a super-wide nuclear powered train traveling around the US. It was called Supertrain! The show was really bad but the model they used for exterior shots of the train was vary cool.
