Based on the front page article about the Dodge EV beating the Dodge Challenger, what are your thoughts about the performance based electric vehicle?

 

Hi Patrick,

One of the ironies of life is maximum energy density is often available at very low rates. Air-metal batteries have terrific energy density but their power is available at very small rates. We see them today as "air-zinc" batteries used for hearing aids. What makes them remarkable is this energy is available over a very long time. In engineering, our challenge is to get this potentially huge amount of energy efficiently to a usable form.

There has been one form of air-metal battery that somewhat overcomes this problem, one that uses liquid metal. They have another problem of heat loss but if managed well, they can produce their tremendous amount of energy efficiently. Just watch out for the 'Sony' versions:


I've been pleasantly surprised in traffic that up to 25 mph, my Prius has respectable acceleration. Some of us have been aware of electric dragsters for some time:
There is a National Electric Drag Racing Association and these folks are a hoot.
