Is NASA Obsessed With Carbon Dioxide? | Real Science

What a pathetic excuse for a scientific institution they have become.

- Bishop Hill blog - Why electric cars are really coal cars

the reality is that only about one third of the energy in the coal or gas actually ends-up as electricity because of the Second Law of Thermodynamics and the Carnot Cycle limit - the other two thirds being thrown away as heat. Thus the electric car is harvesting in terms of well-to-wheel miles only about 27% of the original fossil fuel energy, so not that much better than the standard car running on petrol or diesel. The difference is merely whether about the same quantity of waste heat energy is thrown away at source or in the vehicle.

[And if you don't park your car at a coal plant for recharging, aren't there transmission line losses as well?]

the benchmark comparisons actually are 17mi for 10% loss and 83mi for 50% loss.
