This ‘generator & engine’ uses the magnetic force of permanent magnets.
The magnetic actions power this “engine”. I believe it originates in South Korea.
All the effort put into these devices need to be commended.
I think it is a little over engineered, which I believe impedes the performance. Mechanical Magnetic devices will probably solve many issues.
As usual there are the knockers whom are devout of their own ideas or incapable of expanding their thinking. If it works as per the video, I could come up with a list of uses for this product.
