A Model S with UNLIMITED range?

Imagine having ZERO range anxiety!

This is your opportunity to influence the future direction of EV’s.

There is a technology in the final stages of development, that as part of its technology 'suite' utilizes superconductors, which requires liquid nitrogen to function.

The overall cost of the vehicles will be well below the cost of a current Model S, as the technology generates power on demand (up to 1MW) and as a result doesn’t require batteries or an inverter.

There are two ways to supply the required liquid nitrogen:

1. Recycle the liquid nitrogen (this will add $1,000 to the cost of the vehicle).

2. Fill up a dewar (a specialized container for storing liquid nitrogen) on a regular basis, at a cost estimated to be $10 per week ($520 per year), from the equivalent of a 'gas station'.

You'd still need the inverter, even if this were true. A super conductor would supply DC, while the motor needs 3phase AC. And anything from speed to torque control, needs the inverter to modulate voltages and frequencies by using PWM.
Although I'm referring specifically to the the liquid nitrogen aspect here, I did mention a technology 'suite' that does enable us to directly generate 3phase AC power.

The technology also generates power on a millisecond by millisecond basis. But I'm saying way more than I would like to AT THIS STAGE.
 
Hi CSFTN,

Yes, well aware of the second law of thermodynamics.

And this is definitely not a perpetual motion machine. The technology will very quickly stop functioning without the liquid nitrogen.

The patents would not have been issued by the USPTO if they believed it to be a perpetual motion machine.

The purpose of the post was to simply confirm my thoughts that people would prefer the 'recycling' alternative, not get into a technical discussion.

What are the patent numbers?
 
Just cuz something has a patent doesn't mean it will work. Hate to break that to ya.

Regardless, idk wtf we're even talking about here. Apparently it has something to do with magic nitrogen that will maintain ultra-cold temps needed to keep it in liquid form without requiring huge energy inputs to keep it cold, and that magic liquid nitrogen powers an EV with endless energy via a "suite" of "superconductors"?

WHAT????

:D

1. Recycle the liquid nitrogen (this will add $1,000 to the cost of the vehicle).

1. Effortless, break even in 2 years.
2. Effort 52x / year, wasted money after 2 years.

No brainer?

As physicist Bob Park pointed out some years ago, an average of a half dozen perpetual motion machines get granted patents every year. If anyone is interested, I can supply the patent numbers for several perpetual motion machines that were granted patents over the last couple of decades (I do not have them handy right now, but I could get them together in a day or two).
 
This sounds like bunk. Superconductors are amazing and there are some really trippy things you can do with them, but the ARE NOT a source of energy. Superconductors have no resistance at all which allows perfectly lossless transmission of electricity and there are some interesting effects with magnets which comes out of this, but that doesn't mean you can extract energy out of a superconductor you didn't put into it.

For any vehicle, you need a source of energy to move the car. Using superconductors in an EV would make the losses between the batteries and the motor almost zero and might enable faster launches. But the superconductors are just replacing the copper wire. You still need a battery or some other energy source, or you just have a very cold brick.

The liquid nitrogen is necessary because the class of superconductors that came along in the 1980s worked up to that temperature. The first superconductors required liquid helium, which is much, much colder, very close to absolute zero, the coldest temperature possible. It was a big breakthrough at the time, but the tech stopped. The holy grail is to get superconductors that work at room temperature or even warmer, but the tech is at a dead end getting any warmer than liquid nitrogen temperatures. If the superconductors are allowed to warm up past the temperature of liquid nitrogen, they quit superconducting and actually end up being kind of insulators.

This is like one of those stories someone hears who doesn't quite understand the basis of the story and then they go and repeat it getting some major details wrong.

Making liquid nitrogen requires a fair bit of energy in and of itself. It isn't tough to make as the atmosphere is 78% nitrogen, the raw material is literally all around you. The air needs some pretty hefty cooling units which take energy to run and then the nitrogen is distilled from the oxygen and other gasses. Then the nitrogen needs to be kept cold, really cold at -320F (-196 C), which is cold enough to do severe damage to living tissue as well as make many things very brittle if exposed to it. A liquid nitrogen leak could be very dangerous because of the extreme cold temperature. Things on the car can become brittle and shatter from the cold and it would be very bad it you got it on your skin.

The OP still hasn't told us what the energy source is. If they think it's either the N2 or the superconductors, they are misled. Neither can be energy sources.
 
I don't think that keeping the liquid nitrogen cold is much of an issue. It "just" has to be kept under pressure which can't be a big deal as you often see liquid nitrogen containers on the streets of NYC. I think they have something to do with the steam pipes below the streets.

There used to be some talk of using superconductors as a type of battery. The idea was that you would create a ring and then send a current around it. Since there was no resistance it would keep going until needed. I'm pretty sure nothing ever came of it though and it's definitely not an energy source.
 
Here's what a quick search on Google reveals . . . different, no doubt; workable, probably; commercially practical, not yet:
Earliest patent is from 1970, so the idea has been around a while. Liquid Nitrogen has been around even longer, so begs the question why this idea didn't fly 47 years ago. Still, an interesting concept.
