The eestor capacitor is supposed to hold about 50 KWH if memory serves.
Electric cars are much more efficient that ICE.
You can calculate recharge rates based on the 50 KWH.
So the poster in #51 is way off?
Yes, the dielectric IS everything that really matters, and the measure of it is the dielectric constant of the material (for storage of energy in the polarization of the its molecules) and its insulating properties, which determine the maximum voltage that it can support without breaking down.
But the 5-minute charge is a joke, unless you have your own nuclear power plant. Others have offered some calculations and estimates of what it would require, so I don’t need to pile on.
Add to that analysis this:
A megajoule is about the energy contained in one stick of dynamite going off.
The reason why gasoline doesn’t explode like dynamite in a crash is that it is difficult to achieve the correct air:fuel mixture in the crash. Hot conflagration? Oh, yea. Explosion? Not quite.
5x10^8 joules into a short circuit?
There’s gonna be some fireworks.
sounds like a “pump and dump” stock market scheme...
heard many of these before (zinc-air batteries, sodium ion,
plastic batteries, etc...now they are talking about
virus batteries which use a shell of a virus with cobalt
genetically engineering in it...)...sounds like a pile
o’baloney....IMHO, that is...

The instant storage idea is what makes this smell. 1 hp. is 750 watts; thus, you can only get about 2 hp. out of a standard 110 volt wall outlet. Even if all that electricity could be stored by, for example, electrolyzing water with 100% efficiency into hydrogen and oxygen, it would take quite a while to get enough BTUs of hydrogen to run a car 500 miles. The fact remains, you can’t get something from nothing. The other inescapable fact, as I learned while practicing law, is that the “green energy” and “energy from garbage” industries both contain more scam artists per 1000 operators than almost any industries. People are always trying to get something for nothing or, better yet, convince the rest of us that they have done it, so they can run a scam.
Who knows?
It might be fact, it might be fiction, it might be a fraud. If you believe only the nay sayers, we would still be riding horses.
Technology does not wait for people to change their minds. Discovery and invention come at the speed of the mind.
I believe in the old line, Trust, but verify.
50kwh in five minutes implies at least a 250kw power supply. That's well over a thousand amps at 220v. I think you'll need new wiring (along with the neighborhood).
I'm not an electrician, but I think you could do it overnight with a normal 220 circuit, however.
Good insight.
I thought using capacitor type power source was an interesting concept, but I hadn't considered that the power, once released, would still have to be regulated to prevent all the power from discharging quickly.

I'm still keeping my fingers crossed. We've had some amazing inventions. Maybe this will turn out to be one too.
Oops, my arithmetic is off. That should be 600kw, not 250, to deliver 50kwh in a twelveth of an hour. And that assumes 100% efficient charging.
i agree its’ I ,,would rather get bit by 1k volt at 1 ma than 1mv at 1k amp
Electric motor driven vehicles require only 1/3rd as much stored energy as a gasoline driven vehicle. That’s because the electric motors will convert the stored electricity into motive force at about 90% efficiency compared to 30% (max) for a gasoline driven vehicle.
So there is only 1/3rd as much stored energy to be released as if the vehicle had a full tank of gas.
If the idea of an electric vehicle carrying around enough stored energy to drive 500 miles bothers you, then a vehicle with a full tank of gas ought to bother you 3 times as much, right ?
“It would take 24,000 extension cords to carry this current.”
Just park closer to the outlet then! ;)
Remember this thing only stores energy. You still need the original source: coal, oil, nuclear.
If it's such a great battery, why are they putting it in a little putt putt?
The idea of a full tank of gas catching fire is not particularly comforting, either.
