Especially what is related to hydrogen. I always insisted, that photovoltaic is more or less fake idea. But on other hand I insisted that photovoltaic efficient solution for special cases. For EV is quite efficient solution since there is no need of expensive invertors, the energy volume would be simply increased by 5% improving travel distance and would serve as emergency power as well. For the house roof solution you have to spend lot of money for synchronization with el.grid. And that makes this idea more or less extravagant. stas peterson,

The usual water/glycol "Prestone" mix, or something more exotic? Keep in mind that the engine is run in a much more intermittent fashion, over a narrower range of speeds; and also, how difficult it must be to drain the battery for fluid replacement (to say nothing of <i>conductivity</i> issues).

Ever wonder why electric cars have been around over 100yrs and in the year 2008 they are still in "developement" water cooling for batteries, mean loss of energy!

Sure, they will cost you $165 when you buy a replacement :) ICE cooling fluid is near 200degF, way too hot for the batteries so the two loops must be isolated most of the time. The Volt must have a complex cooling system. So brushed or brushless motors in these pumps?, probably brushed..

I would be the first to confirm that the prices are a little quirky, and that they do try to price to market as much as they can. Even so, I'm gonna be pretty disappointed if GM's cost on those cute little plastic pumps is $165.00 each. We retail a lot of GM parts.
