Try a flux capacitor. No need for water.

There is a thriving business in recycling car batteries right now. Not much needs to change to support hybrids and electrics. It's not like we'd have to create a whole new infrastructure like that boondoggle they call "the hydrogen economy".

Yeah, just banana peels.

You jest...manufacturers are looking to new capacitance models (based on ceramics I thought, but who knows) as a way to replace 'battery' technology. Capacitors would charge faster, wouldn't "wear out" so to speak, and would be made of materials that are easy to recycle.

Yeah, super capacitors that energy dense would be cool, but right now batteries have a huge lead.

Quote:
Such energy storage has several advantages relative to batteries:

* Very high rates of charge and discharge.
* Little degradation over hundreds of thousands of cycles.
* Good reversibility
* Low toxicity of materials used.
* High cycle efficiency (95% or more)

Disadvantages:

* The amount of energy stored per unit weight is considerably lower than that of an electrochemical battery (3-5 W.h/kg for an ultracapacitor compared to 30-40 W.h/kg for a battery). It is also only about 1/10,000th the volumetric energy density of gasoline.
* The voltage varies with the energy stored. To effectively store and recover energy requires sophisticated electronic control and switching equipment.
* Has the highest dielectric absorption of all types of capacitors.

Those weren't what I was thinking of...

Nanotubes powering battery revolution

This story is fairly recent, even though news broke of this direction about a year ago. The term now is "ultra-capacitor", and is based on carbon nanotubes. One of the first use cases they identified was hybrid/electric cars.

yep, as long as I can keep the cabin cool
Maybe we should look into this invention, I hear it's sensational
