... a power density of 520 watts per cubic centimeter. The performance exceeds that of conventional electrolytic capacitors and thin-film lithium ion batteries, though it doesn't match the lithium ion battery formats commonly used in electronic devices and vehicles.

VERY cool.

Only problem with capacitors is that the discharge voltage drops in direct proportion to discharge amount.

Batteries are more constant voltage over their discharge cycle.

[Red Badger]

But they charge up relatively quickly.....................

Fatty acid? Moochelle’s butt must be a powerhouse.

[DaxtonBrown]

This would be an important technology if it comes true.

Capacitors have a MUCH faster discharge rate than batteries. A capacitor can dump its energy in microseconds.

High energy storage requires some combination of high dielectric constant and narrow spacing between the plates. It better be accompanies by adequate breakdown resistance of the dielectric and enough mechanical stability of the electrodes that the energy stays stored, and doesn’t release at unexpected times. Here’s hoping.

Yes, if you need it, as in an electric motor burning rubber wheels on a street!.................

The mechanicals are the easy part....................

Never fly in the US. Too many parties have a vested interest in the status quo as far as IC engines are concerned. Just like fuel cells and advanced batteries, this is a “rest of the world” technology, and not allowed to take hold in the US.

If you push the idea, it WILL be outlawed. If you don’t believe me, ask why LA no longer has a subway/streetcar system.

Do not challenge the established order, only multinationals who can profit from game changing technologies are allowed to do that.

and they are fun to plug into the wall and see them blow up

[al baby]

LA has both not extensive be both do exist ?

At some point, there will be a storage medium that will rival gasoline’s ease of use and energy density. May be a hundred years or next week, but it will happen...................
