Well looking at it another way is like a farmer bragging how much he made by planting a bag of corn. Seed cost $100.00 planted 4 acres & harvested 200 bu per acre, sold it for $5.00 a bushel= $4000.00-100 == $3900.00 But doesn't figure cost of land, fertilizer, pesticides, herbicides, fuel, machinery etc. To get the actual profit everything has to be included. True a gas engine is only about 15 % efficient, a diesel about 20. But when you try to figure where the energy of a gallon went , the waste has to be included. I don't know where you are getting that perpetual motion stuff from. Joe never called it perpetual motion and neither have I.If you can't explain what is in a magnetic field, how can you feel qualified to judge? I have yet to hear from anyone here that can explain how & why magnets attract and repell, what is in a magnetic field, how does the current know which way to go when a wire is passed through a magnetic field or what electricy actually is. I will not hold my breath waiting for your answer. thank you.
