Very simple test, take a heavy pulley or wheel balanced on a stand to spin free. Attach a small 12 or 24 volt motor to this wheel with on and off switch. Balance and wire an alternator just like a car to a 12v or 24v system. When reached peak speed turn it off, the system continues to spin, the alternator continues to turn and therefore you have more energy out than in at this point in time. Yes I understand, it takes way more energy to get to peak speed and when you turn it off that it will simply regain some of what it has lost. But at the point in time the system is off there is more electrical energy out than put back into the system. I believe that Noethers theorem is wrong, I think that the conservation of energy and laws of physics do change over time. I believe that this simple test will prove that you can achieve more output than input by means of propelling the pulley with a series of on and offs. The on must continue to propel the pulley and never stop, and when switched off it must spin twice as long as on. The measurement of speed, time, and work load. The potential energy is the energy at rest. The E in E=mc2. Just a thought and thanks all about circuits I love reading the threads.
