Hybrid car concepts: We need a new Einstein to solve this problem. The hybrid electro/fuel cars are only a small technological step. Using electricity to move a vehicle with the weight of a ton or two, is, thermodynamically seen, as stupid as burning petrol for the same purpose. If the electric power that charged the car battery is produced by a coal-burning power plant (which is often the case in Europe), the ecological balance is hardly better than with a fuel-only driven engine. Burning coal to produce electric power, storing the power in a battery, and then using it to drive a heavy vehicle means a loss of about 97-99% of the original energy the coal had into (0% would be the Perpetuum Mobile, but scientists are already delighted with 75% loss of energy only). The car industry's aim to produce hybrid cars is only partially ecology-driven. It's more the petrol-dependence with raising oil prices and decreasing oil sources that keeps them dancing. Burning biologically produced marsh gas isn't much better. But, if there's no new Einstein, we can meanwhile use bicycles, and public transports (which, unfortunately, are not everywhere so well developped and punctual like in my country). I've bought quite some cars, motorcycles and bycicles in my life, but I was never as excited as last monday when I ordered my new mountainbike, a full suspended Commen?al Meta 4.1, model 2007 (now going with 30% deduction). The most gorgeous bike I ever had. Fast, agile, light. French engineering with japanese parts, assembled in Andorra.
