480 miles at a generous 30MPG = 16 gallons of gas.
1 gallon = 1.3x10^8 Joules x 16 gal.= 2.1x10^9.
At 25% eff that's a total of 5x10^8 Joules/Watts required for the trip.
In five minutes? Doesn't seem likely to me.
A car using this technology would get about the equivalent to more than 100 MPG. Gasoline engines are very inefficient. But yes, they are claiming a very high energy density.
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.
Think of it as a lighting bolt on Quaaludes.
In five minutes? Doesn't seem likely to me.
Maybe it could but my impression was you plug this in at home and if it could draw that much power it will quickly pop your breakers. How do those numbers translate in KWHs, the measure we pay for in our electric bill?
