This is why you have to shut the door on your microwave oven before you turn it on, so it doesn't fly off of the table.
I remember the last timei forgot... it’s now a permanent wall mount
I remember reading a report where they were touting that the design is so fantastic that even the non-working reference control generated thrust. In that case, it doesn't seem that they understand the purpose of a control. It's like saying our new drug is so great that even the placebo control was effective at treating the condition.
It's surprising that nobody picked up on that.
wow, what condition does it treat?? can i buy it NOW?? even if its just the placebo?!?!?! take my money!!!!! 🤣
I *LOVE* your analogy!
"our new drug is so great that even the placebo control was effective at treating the condition" is precisely the path that SSRIs took. Common in the medical industry.
Pfff!
"It didn't work for you because you don't understand how it works. It knows you don't know."
"How does it work then?"
"Um, uh. I dunno."
See me for any help you need xxx
The principle maybe sound but immature. Think of a musical instrument. Vibration itself is amplified from the string through the cavity of the body and amplified in it's distribution through slowing the waves through a series of rebounds.
If this does work with a smaller ID implant with more resonation then it would produce thrust the only problem is it would be delayed in not only output from start but the form fading longer after output has stopped. There is a delay with each bounce of the wave.

Wonderful Anton, Dr. Becky showed your picture during her video last week on types of Black Holes and Megan Tannock commented on your review of her paper on brown dwarfs. And I bet there are others I've missed. Congratulations, Anton. I am so happy more people will find you and the world will be a better place for it.

Very true both Becky and Anton are my heroes

The reason the Mythbusters managed it was that the sail was reflecting the energy from the fan. So it was basically just really inefficiently pointing the fan backwards
The sail became a crude wing when they did that.
And there may have also been currents in the water.
My bet though is that it's TV so....
In short: sail actually gets more efficent when air is blown at it at an angle. At the same time, pulling vector from the fan changes. The effect is that the sail, along with a kiel redirects force and creates slight forward momentum from side momentum all force vectors even out. It would still be more efficent to simply use the fan as an air proppeler.
Technically the reason it worked was due to the shape and size of the sail to the fan so a large enough amount of air hitting the center of the sail dispersed around the original winds blown from it producing backwards force pushing the boat. They showed how changing the size of the fan to sail ratio seemed to change the effects with the sail needing to be at least around 4 times the size of the fan. But yeah, they also showed just pointing the fan backwards was drastically faster than using it with the sail in reverse.
@@BolinFoto Well, the sail IS moving outside air to thrust the ship forward, in a very inefficient and stupid way.
It would be impossible if the fan and the sail were completely sealed off from the external world.
You also got to ask: Why not just turn the thrust 180* and just use it. Even if you could (theorietically) work. Why. Just why. Even if you would get 1% forward momentum, you could still just flip it, and ditch the sail, and be better of.
I'm very surprised that shocking a copper trash can doesnt make it go.
Not exactly what I was going to say, but close enough 😆
If you use enough power it sparks (thrust propulsion).
All that wasted research. They could've just asked you.
@@smoath "Research" ha, ha. Did you put that in your circus application?
No more surprised than the fact that dipping two bits of metal in lemon juice generates electricity.
Of course the guy who had the idea would be upset, it's like waking up from a dream where you are a billionaire
Or worse, the realization that you would have been a Billionaire, if you hadn't thrown out that hard drive with all those worthless bitcoins on it.
@@Foolish188 omg, that would suck so hard
Hahahah
I hate that when that happens.
That hits close to home.
We knew it cannot work. The annoying thing was that we could not reliably demonstrate that.
You cannot prove null result.
@@Alexagrigorieff That depends on heavily on circumstances.
You _can_ disprove the null hypothesis. So choose the null hypothesis to be "EM drive works".
The problem was that the measurement techniques were not good enough to disprove the proposition. Fortunately we have hard numbers about how much thrust it has to produce (higher than photon pressures), so it was very much possible to disprove.
We have now precise enough measurements to state that it does not produce thrust over what current physics allows, this disproves the null hypothesis.
@@adamrak7560
>So choose the null hypothesis to be "EM drive works"
I don't think 'null hypothesis' means what you think it means.
In the case of mythbusters the fan was so powerful that the wind was reflecting off the sail. When they turned the fan around it went much much faster.
So in theory, the same principle would work with EM. Just turn the EM around and have it direct out one side only.
@@ariesdane5876
"Just turn the EM around"
Yeah its called a flashlight drive
@@azmanabdula
or an open microwave without safety systems.
Edit: I have a better one: or a Wi-Fi router with a dish antenna ( they use the same frequency as microwaves, I think it was 4.2GHz )
@@azmanabdula I was being sarcastic. Of course EM is massless and could never provide thrust no matter which way you vector it.
@@ariesdane5876
"EM is massless"
So are photons though
The reason it doent work is because its all occurring on the inside of the engine
And not directing it outside
Like it said in the video
Like pushing your car from the inside
Not a failure. Just learning what does not work. That is just as important as learning what does work.
This was pretty obviously a "does not work" right from the start. Depending on the experiment, it involved random amounts of "propulsion" in random directions for no explainable reason. That just screams experimental error.
@@jasonpatterson8091 and also the fact that this broke all phyical fundamentals right from the start. We just tested around because we would have had to think alot if it worked.
So im weirdly glad that most of our physics still works
Still insane to learn electrons and photons still can provide propulsion in zero-g. But we're still messing around with what nozzles can and can't do. Lol
That’s SCIENCE baby
Hmm I will use the power of my mind to lift a paper clip. No didn't work. Hmm I will ask any ghosts that are in the room to lift the paperclip. Nope, didn't work. Learn anything?
This is one of those tragic cases in science where so many people want it to work that the lacking theoretical and practical evidence are overlooked for far too long.
They are now going to put a big electric fan in a copper bucket and test that for a decade.
Yup. When it comes to people's desire for it to work they will try to find evidence for it to work even where there isn't any. Still thought it was so depressing to see where even the most optimistic tests showed it being about 1000 times less efficient at making thrust than photonic thrust (light bulbs).
I figured out this concept when I was 5. Pretty sure every kid did as well, when they tried to push a plastic toy cart whilst inside it, with their hands. Just rocking back and forth.
@@nate7LP_my_dog_found_the_knife it wasn't really efficient but it was working! :)
This is the effect pop science articles have on people who do not have any scientific understanding or knowledge. And that is most people. It's basically an argument from authority where someone merely claims to be an authority, and pseudo-intellectuals hop on board to pretend they are on the cutting edge of knowledge they haven't earned. It's a PLAGUE nowadays.
There is some pressure on the large and small flat surfaces. There is a difference due to the difference of surface, but that difference is exactly nullified by the longitudinal component of the pressure on the conical part.
Yesnt thats sadly not how em waves interact with surfaces. But effectively yes.
gauss's law bra

@@MrSalsa1995 Stay strong man. The truth IS out there. Or IN there. I hope... lol.
I'm glad they were able to find and replicate the source of the error. Thanks
On MythBusters, when he moved the fan from one side to the other, it redirected the wind at an angle, which bounced off the sail and produced a small thrust. Whenever they had the fan pointed directly at the sail, The reflective force blew directly back into the source with a portion off to the sides.
Isn't that how sails work though? Most sail boats do not have their sails along to the boat's minor axis but at an angle to it. Not a sailor by the way so prepared to be very wrong here.
@@I_Don_t_want_a_handle In this context, a sail catches the wind from an outside (off the boat) source. Having a fan on the boat is most effective facing out, giving thrust. Imagine a fan boat. In the MythBusters' experiment imagine turning the fan on the fan boat the other way and putting a piece of plywood to reflect it. Not at all efficient, but some thrust still is supplied. It has to be at an angle though. If it is direct, it bounces straight back to the source, (mostly) canceling it's self out.
Natural wind, an of the boat source, will push the vessel which ever way the wind blows. This isn't always the exact way the sailors need to go. So they adjust the angle of the sail and the angle of the boat to control where they go. I remember from long ago, they can zig-zag with the same wind.
@@cjvan713 Indeed, I agree but ... IIRC and I may not be, once the wind has hit a sail it has to go somewhere and, I think, if it comes straight back won't the same issue apply as the fan? A cancelling out?
Again IIRC, sails are designed to spill wind, and modern sails are very different to 18th Century ones. Modern ones are aerofoils, effectively. Square rigged sails, I believe, were always rigged at an angle, even a slight one, to the wind rather than 90 degrees so perhaps this is why?
Either way the fan experiment leaves a lot to be desired and I'm not sure that it is a 'fair' representation. Did they blow the boat with the fan attached to a dock and did it move? What was the force applied, was it sufficient etc. I'm yet to be convinced but I do know I don't know if I am right. 8)
Thanks for answering BTW.
I was just thinking about the Mythbusters sail test like three hours ago, lol
I don't see how it won't work. It's just thrust diverted backwards. Of course it would be just more efficient pointing the fan back.
@@carlosandleon -- Some aircraft have a similar system for reverse thrust (for landing and taxiing and what not) where two plates cover the end of the engines and redirect the thrust back around the nacelle.
We knew google listened to what we talked, now it can read our thoughts?
😜
@@nuravanimations3201 Google have enough data to know you better then yourself
The sad thing about the Mythbusters episode is that the device was built by someone who doesn’t understand how sailing works. Sailboats move by wind moving across the sail (which is why they got some thrust when they aimed it at the sides of the sail) not by having wind moving into the sail.
A failure is actually a good thing. It closes one door which allows other prospective drives to be explored further.
go fail more then. prove your theory.
@@zoltanz288 I don't think you understood his point, which is the process of elimination. You can check EM drive off the list of possible drives, and focus on new research for something that could actually work.
Point is everyone familiar with physics said it couldn’t work. This was not an experiment in quantum physics or cosmology where’s there’s still a lot of unknowns. This was based on well established science. If physics that has been studied and tested for a couple of hundreds years tells you that only a literal miracle could make it work, it’s not a surprise that a miracle didn’t happen.
Sure, it’s a good thing that the scientific method has proven its validity once again, but it’s still a disappointing waste of resources that could have been better employed elsewhere. Modern research is extremely expensive, we can’t afford to try any wacky idea people with poor understanding of science have. Ignorance is not forward-thinking.
@@pansepot1490 yeah its the waste of time on a wild goose chase that matters because you couldn't be bothered to put in the work to rule out all the obvious sources of error (which admittedly can require some of its own).
@@zoltanz288 hater face McGee

EM drive is just a modern version of perpetual motion device
@@sciencegirltheai-1minutesc607 The funny thing about perpetual motion devices.......is that they currently exist.
IF you define perpetual as say around 10 billion years.
The earth, is a perpetual(for human scales) motion device, that produces electromagnetic fields.
@@geelee1977 yea but then earth will eventually be geologically dead and lose its magnetic field in the future
@@sciencegirltheai-1minutesc607 Yes that is correct, as I completely already pointed out.
However, for the human race, for ALL intents and purposes, it IS perpetual, from a homo sapien perspective(much like from a photon's perspective, being as it travels at light speed, as soon as it exists, it then non-exists, but from our perspective it can exist for billions of years)
It is a fun fact, that there are 2 definitions for perpetual in the dicionary, and this is one of them:
*occurring repeatedly; so frequent as to seem endless and uninterrupted*
So, um, yeah, yup, meets that definition.
It is highly unlikely, Homo Sapiens would even survive as a species before it stops.
Either via extinction, or via evolving into a new species. So from our perspective, it is indeed forever. Actually, it is forever, for millions upon millions of entire species, past, present, and future.
I am fully aware of what the laws of thermodynamics are, and that literal: "lasting from start until time is exterminated in the universe" is impossible.
🤣
FINE! I will take the microwave out of my spaceship engine!

@@phatphat7089, I'm not sure why anyone ever was hyped about this anyway. Magnetrons take a ton of power to operate, and EM waves are massless - thus you'll never get a net thrust because a differential can't exist between two massless areas.

One of your better videos, by far. I loved how you set up by giving the history and prior discoveries/publications of the EM drive before leading into the most recent paper debunking it and why.
Good job, wonderful person.
You always provides very rich and fresh informations
If you have to keep testing something over and over again for years trying to figure out if it does anything - it doesn’t do anything.
True.🤔

It’s too bad the EM drive didn’t work, I’d had high hopes for it. But it goes to show that our current understanding of the laws of physics is very solid.
Pushing the sailboat with fan side to side is called tacking. But the sailboats have a keel, it keeps the boat from going sideways.
The issue is that the fans force would counteract the force created by the sail, nothing to do with simple sailing techniques
This reminds me of the theory of man flights before the Wright Brothers. Years from now people will say "We didn't know how simple it would be to build a sunlight drive" ..
Might want to check out Thermocouplers
Many, many, many people were working on airplanes before the Wright Brothers. They came up with 2 innovative devices, wind tunnels and an aluminum engine. Their idea that warping the wings was the best way to steer, was already known to be wrong headed in France.
@@Foolish188 The Wright Brothers are actually kind of doubtful as inventors of the airplane. Their original design could never be replicated in working condition, if anything it seems a latter model of them did the actual flight and there was a German, Gustave Whitehead who was reported to have made several successfull flights roughly a year before them.
Yeah. But then explain birds.
@@craigwall9536 Also controlled, powered, heavier than air flight is anything but simple. If you have a really solid grasp of the very complicated theory behind it it's "easy" to build a plane, but that's like saying it's simple to build the LHC because it's just a bunch of magnets and pipes.

This is exactly why thorough and rigorous peer review is a must for any scientific results from an experiment to flush out possible flaws in process causing erroneous results.
good balanced and accurate. I like that you acknowledge we should keep looking for unusual types of drives, even though this one didn't seem to work.

The Great Snickernoodle in the Sky approves this message.
I don't get it
RIP EM Drive. Like too many people these days, we wanted you to work even though we knew you wouldn't.
2:33 That's a crude thrust reverser, like the kind you have on an airliner engine.
The magnitude of the momentum change of an air molecule bouncing off the sail is potentially double that as when it got whacked by the fan blade.
By the same principle, it is easier to knock down a large, tall wooden block with a rubber ball than with a ball of clay with the same mass.
So indeed, you could conceivably use a fan blowing on a sail to move forward.
“What the Math”: expanding our knowledge base one video at a time. Thank you and take care, amigo.
I come here daily for my dose of science! Great job, Anton!
I really like the "you can't lift yourself by your shoelaces" analogy
but you can boot your self by your bootstraps :)
The problem with the EM drive is and always has been that there's a fundamental operating principal which makes sense... but requires excluding so many other fundamental principles to actually work. But on the plus side, we've learned a lot more about how this doesn't work, so the next crazy idea won't take so long to (in)validate.
I remember something an engineer friend used to say: "That was a good idea. Too bad it didn't work."
I don't get the conical-shaped "chamber" to create thrust from standing waves. Standing waves are _broken up,_ not strengthened, by converging/diverging walls.
Fan on sail? It works for Wile E Coyote!
A fan mounted to sail boat would actually work if it's angled correctly and not perpendicular to the sail while also not being parallel to the floor of the boat. It wouldn't be efficient at all but you could slowly make it move forward.
I'm very surprised anyone actually took the EM drive seriously.
I don't think those who took it seriously actually expected it to work, but all the best discoveries are when what happens is different to what you expected.
Even if it's improbable it's possible
@@limesta in my opinion this always was an impossibility.
If the Earth was flat .. it would have totally worked!! 😏
All that wasted research. They could've just asked you.
I was listening to something that was pretty loud an really annoying, and I switched to this, and your voice instantly made me feel better XD
The sail boat tests was from the venturi effect moving the existing volume of air. As they turned to the side it would create a low pressure and move the air on the opposite side across the sail. The same effect can be seen in an air foil in a stall angle of attack.
I'm glad I didn't waste much time following the em drive; i never read more than the headlines.
Clancy must be devastated
The headlines amounted to "Another engineer does not understand basic physics".
That's ok. NASA and DARPA wasted it on your behalf, spending millions of your tax dollars doing so, all the while knowing it was a ridiculous proposition. But what the hey, it's other people's money right?
@@chuckschillingvideos They also tested some alleged form of antigravity. They like risky proposals but in this case I agree that they wasted the money.
Ah I remember this, everybody thought this was a bad joke here in the UK. As we say over here "on your own mate"
Anton throwing some shade at Shawyer. Lol. Great vid
It's just a modern take on classic perpetual motion machine like an overbalanced wheel. The "thrust" as conceptualized requires an incomplete analysis of the forces involved. In this case, it looks like the error may have been ridiculous blatant in that the diagrams seem to be considering forces on the end plates but not the sidewalks. The microwave photons will produce a "pressure" of sorts meaning forces applying equally from inside the device into its walls. The difference in force between the end plates will be equalized by the net force on the tapered wall (which will have directionality perpendicularly toward the large plate). Another error occurs in confusing the speed of photons with the speed of standing waves in the cavity. This makes his calculations reveal a significant loss if energy from the system which - when properly calculated - also has a net zero effect.
I'm not surprised that something running on radio waves won't work
cause no one listens to the radio anymore. you need hope to ride on radio waves :C
Video killed the radio star.
Not even .mp3 would work in 2021, let alone radio
Rockets should be a about Spotify and his streaming clones
I mean, you can still drive a vehicle with radiation. Solar sails wouldn't work otherwise.
Er... it never worked to begin with!
Finally I can stop hearing about it anymore. So many tests showed it did nothing with even the most optimistic ones showing it being weaker than a photonic engine. And then the creator here is saying "it will give us flying cars". God that hurts to hear.
"naturally, this would _probably_ not work"
Nice job qualifying that statement Anton! Just in case someone designs a windshield-pushing powered car haha.
You wear Mario Shirt and finally call out the BS with this EM drive.. I will subscribe and send money.
@Nopey No no.. I'm not a liberal.. I believe in science. But thanks for trying.. Your prediction is off.
Once again, experimental physicists to the rescue.
The problem is replacing conventional rockets instead of aiding them . A body at rest stays at rest.. so sending electrons through the walls would only. Heat up the walls . And the fact the heat gave slight push or made it lighter. In my book it did work
Anyone who sails know that you can generate lift by moving the sail from side to side in dinghy racing (not possible on larger boats). It is called pumping the sail in English. People do it when the wind drops however it is outlawed by the yacht racing rules.
it's not like most of us can say anything truly poingiant about this, so i'll simply say, holy shit Anton, your greenscreen and lighting are almost flawless. well done for making such a sharp and well defined edge, besides the EM drive, i literally just realised how well you've done your keying and lighting. for just a dude, that's very impressive. i guess the Em Drive is a sad but an expected thing anyway.
Anton: Does this mean that the EM Drive is impossible?
Me: *Expects something like no evidence blah*

As long as scientific endeavour continues this can be marked as a step forward. Now we can open our minds to new ideas. We carried out the experimentation and proved our hypothesis wrong. This is progress
Well the issue really was that the hypothesis was bs from the start.
I'm not sure all hypotheses are worth testing.
If some said "painting shoes the exact right shade of purple will let you jump to the moon", then it's not worth anyone's time to test it.

@@nex4613 THE WONDERFUL PERSON EXPERIENCE
I second this!!!!
I wanna see Lex Fridman style podcasts! I'm so sure Anton has wonderful things to discuss with his guests!
Noooo! Hope dies last. But I guess now it‘s dead for real. I‘ll just go and cry for a minute.
Trust me hope ain’t dead... they’ve been able to go FTL for 70 years.... muuuuuch faster 🤫
@@addamriley5452 Well, we only need two black holes, massive radiation shielding and really brave volunteers ... or just humanoid robots :D But you‘re right!! In 1000 years EM drive will be a joke of the far past.
@@MauriceM. actually they don’t need any of those 😅. What made you think they did?
Well... no need to cry.
The speed of your own imagination should prove everything you wish to know.
@@addamriley5452 In short, Star Track. I might be out of date. Like obviously 😂 If you don’t mind, what is the current most efficient theoretical way of achieving FTL ... in my mind it would be bending spacetime in front and behind the vehicle. But honestly I‘m everything but an expert when it comes to this. I just really enjoy the topic.
It's funny because even I, some random Canadian bumpkin, called it as thermal. If it were the result of some weird standing wave thrust in the cavity the rate of change in force on powerup would have been much faster. The force curve looked like a textbook example of something heating up.
Blowing a fan onto a sail works because of you blow one side more than other you redirect the air and get lift. In the middle you get it stalled. Sails are airfoils! So if your sail was initially 90 degrees with the boat, you blow one side, it flexes a bit, the air goes that way and you have a small angle, that component makes the boat travel...
i hope someone out there is dreaming up the next crazy space engine even if this doesnt work.
Dude have you seen the new thrusters they're working on?
@@confectortyrannis275 Nuclear Thermal, and Nuclear electric look like they could be really promising!!
At least they're still hard at work trying to get a warp drive to work. They even theoretically came up with one that doesn't rely on nonexistent negative energy. Now if they can just figure out how to keep it from turning into a black hole, and then how to push the thing...
@@JustinMShaw and where to get that mass from. And yeah the whole breaking the lightspeedbarrier is still thought to be impossible sadly. Just because there could exist a spacetimebubble moving above lightspeed doesnt mean we could create and accelerate one
@@JustinMShaw but even sub light speed warp drives would be huge
I can be motivated by chocolate encased in a sugar shell. I think that I might put in a application to develop an M&M drive.
LOL
I would invest in that startup.

Say hello to decaying teeth and diabetes
1:37 I like how he said it probably wouldn't work like it might work somehow.
Awesome video! hey you keep rocking on
Finally we can focus on real science again XD
From the creator of the device, yes poor science , but from the perspective of knowledge , testing and failure , no . It will have its place in preventing repeats and deeper understanding of the mechanics of radiation .
Well aren't you mister superior!
NO SHIT, like new wave space propulsion is gonna be a breeze to create.
Warp 10 Mr Sulu. We need to catch up to the Romulons and their hyper space drive.
The small amount of momentum generated in the Mythbusters experiment was likely due to the oscillation of the fan from side to side. Each movement causes the sail to slightly move ahead of its opposite side, which alternately regains the original position, thereby inching forward slowly. The microwave field of the EM may do something similar, In any case, not much is converted into forward motion.
Proper Science means you don't dismiss something "just because". You do the tests to PROVE something doesn't work, and usually learn better ways to test things while doing it.
If you can't make your machine work before the patent on it expires, there might be a problem.
If Clarke had filed a patent for the geostationary communications satellite, it would have expired before one was actually built.
In the case of the sailboat, it's not like pushing on the inside of the car, because the air is coming from outside the boat.
If you were blowing air at a sail perpendicular to the fan, the forces would cancel. If you blow the air an angle, it would twist the boat (same principle is gyroscopes rotating spacecraft, no laws violated) and the friction on the keel (which is the outside force) propels the craft forward.
I don't know if you can do it in a car, but the principle is the same. Many people have discovered you can propel a bicycle forward by wiggling tire back and forth. This is in reality more like walking than a violation of the laws of physics, and that's what happens blowing a big fan on a boat sail, it's just not as obvious.
My bet on the fan on sail experiment: since it produced thrust when blowing to the sides, it was creating torque, and the counter-torque on the keel from the water produced thrust.
Fastest form of travel is the mind.
... what? No.
And gossip is the only thing that goes faster than light.
@@matthewdavies2057 Whose gossiping lol
@sᴀᴠɪᴏᴜʀ ᴍᴀᴄʜɪɴᴇ You would only need thought. No rockets needed.
@sᴀᴠɪᴏᴜʀ ᴍᴀᴄʜɪɴᴇ Oh yes. Coordinates are key. I think that's how I ended up in this....sigh...place ROFL
Never thought it would work. Now, the Epstein Drive, yeah, that’ll work for sure. Now, where’d I dock the Rocinante?
The sailboat example is how jet engine thrust reversers work. They create a thrust "diverter" and literally blow on it. It's not the most logical thing to do but it does work and helps slow the plane down.
As I recall even with the measurement error wasnt the force generated down on the same scale as just pumping the same amount of energy into a flashlight would generate? We can already do that for a "Reactionless" drive, the only problem is the thrust is so low it will take you forever and a day to build up any appreciable speed.
Here comes another piece of technology that confirms it doesn’t work but will not die and will not stay dead, just like the Archimedes Death Ray.
Hey tell that to all he insects I killed as a kid with my magnifying glass
the emdrive is just the latest in a LONG line of such devices stretching back hundreds of years... so yeah... not going to die anytime soon. the inventor has already shifted the goalposts to requiring 'superconductors', so he has his next 'go faster stripes' already planned out.
I recall looking at the math behind EM drives years ago and predicted it could only work if the Cone was replaced with a equiangular spiral cone (I cannot remember now how I deduced that logic).
You were probably drunk at the time.
Acid
Great explanation, thank you.
Seems like more of an acoustic rebound principle. Much like a violin or guitar. where the cavity itself reserves most of the energy but does not release it all at once. Adding a more malleable density or thickness on the inside might be the primary point at which you get some form of thrust from it.
Pretty early, but not early enough...
I was late... fashionably so.
Too early to sail the stars
The world in shock!
I was rolling on the floor when you said that thing about trying to push on the windshield 🤣
I think a better drive is the wobble drive. Place a cordless drill on a skate board. Make a fly wheel out of some 1/4" plywood, and a center axis out of a 1/4" bolt with washer and nut to secure it to the fly wheel. you have to make the wheel out of balance by attaching a weight to the outer edge by drilling a hole and using a short 1/4" bolt, and nut. Place the fly wheel in the drill chuck. Place the drill on the skate board, and secure it with some tape. The drill should be laying flat with the fly wheel to the side. Turn the drill on to a low speed. The skate board should move back, and forth. Now slowly increase the speed until it move in one direction.
