While reading up on the various full electric and hybrid car models now available, and despite the much-vaunted new battery technology, it struck me how little real progress is being made for a practical, long life, high energy vehicle battery. Crunching numbers, it seems that new models have very modest actual specific energy, at the road, of less than 100Wh/kg. Gasoline has 10,000Wh/kg to put that in perspective, so even at 25% efficiency it seems far superior, [and take away the Gummint subsidies and sales would probably plummet]. Toyota use NiMH in the non-plug in Prius, [Prii?], restricted to about 35-75% of full-cell capacity for life-extension - and which will give no better SE in practice than Edisonís 1906 alkalines, albeit at higher discharge amps - and no gassing Ė but Edisonís cells will literally run for 100 years! Li-ons are similarly restricted. Go lower than 20% of full charge and the cells are ruined, and they deteriorate fast, no matter how they are treated. The new Tesla Sedan has a claimed 200 mile range - but the battery is a mighty slab that occupies the entire floor pan, 8Ē thick or more. Here, like Brunelís first transatlantic steamers, range has been won by building a really big, big ship, reducing drag to 0.24 and filling it with coal to the gunnals! frown

..and here's the genius whose vision has ushered in the Electric Age. This interview is with one of the most extraordinary visionaries alive today, Elon Musk: PayPal, Tesla, SunCity, SpaceX. If you can't watch it all, just look at 17:40>. Incredible.
