In this fascinating video, we explore the concept of a free energy generator using a spark plug and magnet. Discover how magnetism can be harnessed to potentially create sustainable energy sources.

But powerful magnets are usually large and energy hungry. Chukun Gao at the Swiss Federal Institute of Technology in Zurich ...

In brief: A team of physicists believe it may be possible to harvest electricity using Earth's rotation through its own magnetic field, and they've published a paper involving a test that appears to ...
