It will lose money just like that really dumb Orbital Reef idea. Low gravity is really bad for you, like smoking two packs a day bad for you, in low gravity your heart begins to enlarge after 9 months and your bones start to become porous. Gravity is the reason we will won't ever colonize the moon or Mars let alone the other complications like radiation and you can't grow food in regolith you need soil and neither the Moon nor Mars has any.
@@LePageChannel Ahh I get your confusion. No Blue Origin is not developing the Dream Chaser. They did partner with Sierra on an idea for a commercial space station, but not the Dream Chaser. As far as I know the only other space company that Blue Origin has deals with is ULA for the BE-4 engine they are developing, but Blue Origin is so far behind on that, I am not sure ULA will continue their partnership. We'll see.
I could watch these all day, they're totally going to mine meteor belts and eventually the Oort, I think that rock they were talking about on here is the one that has more gold than mankind has mined in its history lol
I was thinking of that with the Orbital Reef. You cannot walk away, and you are literally within a short walk of your desk 24/7 as long as you are there. You also cannot have inspectors just drop in unannounced. That has a lot of potential for abuse of the employees (also known as "serfs" or "slaves").
The US, what a great country; the very thought that you need armoured police cars is concerning. I am so happy to live in a country where this would seem massively extreme.

Ok but we genuinely enjoy our firepower. We have entire industrues devoted to it. Shooting up cars is fun. We own some property in central Texas. In 1973 my Dodge 100 crapped out and I left it where it died. Over the next 30 years we dumped tens of thousands of rounds into it. Only rule was you can't shoot the rear window. I shot it out in 1989 when my girlfriend left me. I haven't been to Texas in 30 years but we still own the property. When I left Ann Richards (D) was govenor and the Cowboys won 3 out of 4 superbowls. I Ieft and the State went to hell. I do feel some guilt because of that.

My best friend's uncle invented injectors that gave a v8 80 mpg... one of the oil companies bought it, and we've never heard anything about it since. I hear this isn't an isolated event either.
I think this will only work with conventional gas engines that require spark for combustion. Not sure how this could disrupt a diesel. Looks like we need to go back to manual pumps so they won’t get stopped
Because we all know this can be abused and will be abused. Will they make manual illegal, most likely so they can continue to use the new tech unhindered. Also using this on unaware motorcyclists just seems outright dangerous. Engine instantly cuts out a part locks and the motorcycle goes for a dive.
Im bored to tears knowing that real genius inventors have lost their lives, their work stolen and secretized. So that we can continue living on an antiquated energy grid and bankrupt financial system.
Funny, but I invented what this video is calling "RF Safe Stop" over 30 years ago. The team tested it on various vehicles and it proved 100% reliable and affordable for law enforcement and military applications. Just could not find financial backing for mass production of the device. Glad someone did.
It's a tax-deductible jolly for people who will produce more emissions getting there than you or I will in a lifetime. No one needs to go into space just to sit at a desk all day.
those trailer shrouds would just get ore up going in and out of the docks. lumpers are doing that job for a reason and they will mangle those without a single thought.
Because of the way supply and demand work, all that extra material in the asteroid would reduce the price of those materials. So it's not actually worth quadrillions of dollars.
If a vehicle's engine is remotely switched-off, that vehicle will loose its power assisted braking: its brakes would be useless (the vehicle will then become dangerous ) How do they intend getting around that aspect of the idea?
What aspect? The vehicle was already dangerous as the driver was not braking before the engine is disabled and would just keep pumping the gas pedal after the engine shuts down. For your question to make any sense there would have to be an intent to brake in the first place.
As you mentioned they are “power assisted” brakes. They do not lose the ability to stop the vehicle, it is just more difficult because the booster will no longer be assisting the braking effort after a few applications.
Back in 2008 a guy with a laptop shut down a bunch of GM's in a few square blocks just to prove how fallible the system is. No security updates to the system have been completed since then

Bad enough we, as humans are screwing up the earth now we're tossing garbage into space ! We got no business going to other planets till we take care of this one !!!!!!!!!!!!!!!!!!!
Gold is very valuable because of scarcity, get another source of a lot of it and it becomes as valueless as printed paper money when it is continually being printed.
It's hard to believe that they compared that Chinse robot to the Boston Dynamics robot. I'm sure it will be cheaper, that's what China is good at. The Boston robot can do backflips that most humans can't. The Chinese one looks like it can barely walk without a chaperone.
Let's get something right, they do not want to save money. Nobody in their right mind does. Money has very little underlying value. All it's values have become superficial.
The bullet proofing in cars shown here at 1:40 is 20 year old tech used in Brazil and other southamerican countries... 200,000 cars a year are using this these bullet proofing methods and even better methods than shown here... not a "new invention that will change the world" as the title says...
I think it goes back to the first armored cars. 1930's. I know warlords were doing this since the 1960's. Perhaps they meant a militarized police to enslave the population. :)
The ballistic door could be easily accomplished by putting a layer of Kevlar inside the door panel. Surprised this hasn't been a standard inclusion of all police/government vehicles. With the alleged success of biped robots, why hasn't one or more of these been deployed to Mars. Seems it would manage the terrain better than the rovers we've sent thus far.
one immediate problem I can think of is the square cube law in that they are mostly reliant on solar energy, and there's not a lot of surface area on a bipedal robot... Maybe nuclear technology's advanced to a point where they could incorporate it without affecting the center of gravity too much. But I can't speak on such things. I'm just saying they know more than we do, and they're not doing it: so I'm sure there's a reason...
