    I saw brochures where the electric coop in Woodland, WA was trying to get farmers to install hating cables underground in fields - sometime in the 50's.

      Pick them up before plowing or cultivating and lay them down again after? There are good experiments that show that heated soil gives plants a head start in cold climates. Adding even more fossil fuel use to what goes into fertilizer production.

        Most greenhouses will use soil heating cables - I have that back in Izmir. Heating the earth though is a different critter. At the time hydro power from BPA was cheap and plentiful.

        The next step was when the state power board, made up of small business men, ordered five reactors - none of which was built due to lack of requirement for the power - seems their power demand curve looked like the infamous hockey stick. Cost them billions in 1970 $ to shut the projects down and Washington went from very cheap power to expensive power.

        Small businessmen were playing with the big boys and found out who was smarter.
