Simple: there's already a good-sized market for that type of vehicle.
First, I think gas engines are only about 12% efficient. Second, I think an ultracapictor discharging would be a lot more spectacular than a gas fire.
I doubt that 1mv would do it -- but if a thousand amps is hovering around somewhere where I can touch it, I'm in the next room, thank you very much.
“The result is an ultracapacitor, a battery-like device that stores and releases energy quickly.
Batteries rely on chemical reactions to store energy but can take hours to charge and release energy. The simplest capacitors found in computers and radios hold less energy but can charge or discharge instantly. Ultracapacitors take the best of both, stacking capacitors to increase capacity while maintaining the speed of simple capacitors. “
OR, you could make your own railgun. Now That would be cool!
Schwarzschild would probably say there’s a mass-ive hole in such criticism and he and Compton would probably be on the same wavelength.
Not really. Someone has to produce the electricity for electric cars. Where do you think that will come from?

Captured cow farts will be used to power huge generators.
If it sounds to good to be true, it probably is. The odds are good this won’t be the revolution we need in technology. If it is, then great! Every once in a while, technology is discovered that does what was believed to be impossible. Here’s hoping this works.
Bump for later read.
I’ve been following this story for over a year. Fingers crossed.
Five hours with a 220V circuit drawing 50A, even with charging losses, which are much lower charging a capacitor than they are with batteries.
So you could recharge at home overnight easily.
The five-minute recharge would be done at a “gas station” and transferring from the station’s own bank of capacitors to your vehicle at very high voltages and low amperage. Low amperage means small cables, not “as thick as your arm” as someone else suggested.
The bottleneck would become the electrical service to the stations. To recharge 500 vehicles per day would require 50kwh x 500 = 25mwh per day. 25mwh / 24 hour per day means an average draw from the grid at 480V of 2000A. That one service station would be drawing as much power as 1000 homes.
[but if a thousand amps is hovering around somewhere where I can touch it, I’m in the next room, thank you very much.]
Very true. The little capacitor in a common battery powered camera flash can be deadly.
Everyone can get a charge out of this.
Think of it as a lighting bolt on Quaaludes.
Dang! I thought you were the doctor in “Smokey and The Bandit”.
I hear ya,,
my personal opinion about this is magnetism is the best and the most feasible propulsion,,or if you were to put a gen. and mtr.end to end , with the gen.producing enough power to run the mtr and accessaries,,would it work,,something to ponder,,but what would we do with all these IC engines...??
That’s assuming 50kwh will power a car 500 miles.
I’ve seen several products described but the product I believe they are talking about is a 50,000 watt hour storage, maybe a 100,000 watt hour. Either way, it is not 80,000,000 watt hours.
“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.”
If you had a similar unit in your house for emergency backup, you would not need your own nuclear power plant. 5 minute recharge would be dangerous and would require significant engineering but is posible. A more likely scenario would be overnight recharging at home and unit exchange on the road.
I don’t see any magic, but a fair amount of hocus pocus here. Barium titanate dielectric (a type of ceramic) capacitors have been around for decades, and while it is true that they perhaps give such a high volumetric charge capacity that they could replace batteries under laboratory conditions where cost is not an object, the charge/discharge cycle improvement over batteries is more incremental than revolutionary, and to build such a large bulk capacitor that operates with acceptable reliability and temperature stability over the automotive temperature range amounts to a huge exercise in improving component reliability.

That sounds like over unity, otherwise referred to as “perpetual motion”.
