I don’t think it’s a scam, but I know there isn’t a free lunch either. It may just be a neat gimmick because the cost of the magnets themselves might not be worth the cost of the set up.
There are quite a few videos out there and there doesn’t seem to be any scam to them. So. I’m just wondering if it would save you money over the long run or whether the magnets would become demagnetized before you saved enough money to pay for the set up.
I think most light bulbs are powered by magnets and copper wire.
They are called generators, and work in everything from hydroelectric plants to windmills...
If this was working then the magnets must be giving energy and therefore mass to the light bulb. Also an electromagnet must be power by a battery or be spinning to generate an electric field. This device is impossible.
If it did work I would wrap that bulb with solar cells and see how much energy could be pulled from it...
