What's wrong with Gravatron? It's a metal(probably not) that floats because it's the only metal that does not change weight due to it's given temperature? You're find it one day...
Nickle may work but probably will only bend the field in to a different shape. Think some coins are made of nickle. I gave up, I know there's the sea and all that but were supposed to be here forever.
I came up with the perpetual motion car, guess called the gravity motion car.
If it can charge for a day may be able to post the Patent application,
To be honest, you're only about 3 years behind me.
I have 2 different types of propeller wind type devices and better motor/generator designs along with my 30 other inventions. And possibly using these propellers on a wire for high altitude wind or sun power generation. Things may be OK.
I have an invention that may surprise you. It moves and can't be moved back. Not built it or have the design fully still in my mind... yea, something like that but different. Came from an idea for earthquake building protection.
What does this post have to do with the original question?
Trying to design a perpetual motion machine is like trying to design a machine made of pumps, tubes and containers that will give more water out than you put into it. It just doesn't work.
