Thunder_Chicken said:An experiment was performed back when the shuttle was flying to produce electricity from the Earth's magnetic field by stringing a 20 km tether between it and a satellite. Same idea as moving a wire coil in a generator, the only differences being that the Earth's magnetic field is much weaker and the shuttle moved a lot faster with more momentum. BobbiLynn - your hubby could do this, but he'd have to skip rope with the cord pretty darned quick to get any power out of it. The concept could also be reversed - a current run through the tether could apply a force on the tether and move the shuttle (in theory). That is like reversing a generator and making it into a motor. EDIT: Here's a link: http://www-spof.gsfc.nasa.gov/Education/wtether.html
That was a great read. People once thought the world was flat. The experiment you talk of is not different. It is like an old day ship caption that will soon find out the world is not flat. Or something like that .
This country was not built by men tat couldn't see the future. It was built by men who conceived the future.
