Fun picture.

About global warming, yesterday I saw a movie on Greenpeace website.
Apparently (in Britain etc), 2/3 of energy is wasted, and only 1/3 becomes electricity. And the heat from the power plants are wasted by sending them up the atmosphere.
But with a technology (which is in use in Netherlands, Denmark, etc), it would be possible to use that heat to heat up buildings, and it would make the power plants twice as effective.
