Andy Grove, former leader of Intel, is proposing the retrofit of millions of US cars at a cost of $10,000 each, with a 10 year payback. Intel used to make batteries.
Cars have a median life of 9.2 years before the retrofit, over which we must depreciate their original purchase price. Adding $10,000 for a battery retrofit to their cost means huge depreciation. If you retrofit a 5 yr old car, how long do you extend its life? Little, I think. In fact, you may be shortening it.
Batteries proposed by Grove are Li-ion, but little or no production capacity or technology exists in western world today; its all in Japan, China, Taiwan, etc.
I cannot support this proposal. It's wrong headed for the above reasons.
Electric may be good for ultralight, small commute vehicles. Hybrids make good sense. Toyota got the 10 year jump with Prius when GM canceled their E-1 design flop. Bought off by Big Oil?
Fuel cells have efficiencies of 36% to 45% (hydrogen to car drive electricity). If you combine the production of the electricity by the public utilities, that is then used to make electrolytic hydrogen, that has to be compressed & delivered to fuel stations, then loaded into the car, we have an overall efficiency as low as 17%.
A modern diesel engine gives 22% efficiency, and is therefore better today, and will be for decades to come.
One hope is fuel cells that burn hydrogen peroxide. Using an enzyme from horse radish (where do these scientists come up with this stuff ?? Was he eating a roast beef with mayo & horseradish sandwich, and dripped some on his electrode experiment?) they have achieved an overall electrolytic efficiency of ~171% (ie. both the anode and cathode produce hydrogen peroxide, so you get 2 peroxides for every electron flowing [ie. 200% efficient], then lose some of them for a net efficiency of 171%). Still at test tube stage.
70% Peroxide has been used in missiles & rockets for propulsion, and is a very powerful fuel, and has better characteristics than hydrogen gas or liquid. Can be easily pumped like gasoline. Spills bleach everything, then turns to water; not bad for the environment, better than gasoline's effect on water table. This is the fuel for the future.
