  •  That tornado idea is really dumb (5+ / 0-)

    They use heat to create a tornado and then try to get the energy out of the tornado. Why not just use the heat to begin with?

    Power a Stirling engine with that heat!

    The comments at the tornado story link are pretty good. Such as, "This has a great B-rate disaster movie written all over it!"

      get the tornado started.  The energy in the tornado comes from the difference in temperature between the air at ground level and the air at high altitude.  

      A poor analogy: when starting a car, electrical energy is extracted from the battery to run the starter motor.  This then starts the gasoline or diesel engine and the power to move the car comes from the fuel via the engine.  

      Renewable energy brings national global security.
