In this bloom of optimism about ultracaps as energy storage for cars and a
theoretically high recharging rate, do a reality check on the power
involved. You fill a gas tank in avout five minutes with enough energy to
drive a car at 70 mph for several hours -- and you are going to charge the
capacitor with that energy in minutes? The power is in the hundreds of
kilowatts -- do the arithmetic yourself. The 'gas' station may have to
service a dozen cars at the same time on an expressway in the middle of
nowhere -- you need a major transformer substation to supply the peak
demand.

Hi,

The Better-Battery, or bettery - might be a reality in 2007 - Finally!

At 15 kWh/100lb it has about 8 times better energy density than a
conventional
lead acid battery, and being an ultracap, it should be rechargeable, at a
"gas"
station, in about the time it would normally take to fill the tank with
gas.

Competition provides the motivation,
Cooperation provides the means.
