We can cut our energy use by 1/3 just by moving heavy industry that uses the most power into space. We travel far too much--half our wealth is in our rusting cars and potholed roads. We could do a lot better if our planners were awake.

By harvesting the waste heat alone, we can forego building power plants, and of course reduce our use of coal (which remains #1 as our electricity source). The reason it won't be done, however, is so opponents of the strategy (present company not referred to) can push their photovoltaic agenda.

But what about the energy and resurces I'm saving by not buying a new car? ;-)
