Over the years there have been many claims of free energy created by just the right configuration of magnets.
It usually involves employing a "magnetism-blocker", which invariably doesn't actually do what they think it does.
If they had actually made a machine that works, then it would be simple enough to make a prototype (that works), put it in a sealed box and get it to power something (a light bulb, radio etc) inside the box. Allow people to inspect the prototype first for batteries.
This whole "Jury Led" business is just silly. It works or it doesn't.
