Solar and wind are good energy sources, but they are not the best and won't be the future. Zero Point Energy will. Nikola Tesla is a name that is not commonly known. If the name is known, seldom is his work. If all of his amazing technology was incorporated in our societies the world would be a completely different place. Nikola Tesla and countless others after him created technology that could harness and distribute unlimited energy. Some of these devices didn't even have moving parts, which would lead to it not breaking down. Contrary to belief we do not understand electricity. We don't even have proof that an electron exists.
For example: When Nikola Tesla was in the US he created the Wardenclyffe Tower which would harness energy from the ionosphere and distribute it wirelessly for miles. As long as you were within the radius of the tower you had unlimited, free energy. Tesla was being financed by J.P. Morgan who asked where the meter would be put to charge the people. Tesla replied that it would be free to all... You can see why it was destroyed and hidden.

A lot of people keep trying to make o-energy engine designs, but it seems a lot of them need a little help to maintain centrifugal force. Why not both?
Some do, yes. Most don't. There is/was a fellow by the name Steven Mark that created a device with no moving parts that would produce unlimited energy with no primer(in the conventional sense) to initiate or to maintain. It uses the Earth's electromagnetic field as an energy supply which it converts to something usable by our electrical items.
