Even though none of these ideas will achieve complete perpetual motion, many of them may be viable solutions to supplement energy consumption for greater efficiency, so we can joke about it but all these engineering minds here have a good chance of coming up with some good ideas. I give the original poster lots of credit for thinking along these lines and participating on this forum. You should be proud of yourself, keep it up and try to stay focused on the right things as you go through the next few teen years, which are very difficult years that have many, many bad influences along the way.
