Seeing is believing. Well in this case not even seeing is believing.
I've seen videos of Shawyer's work twisting away on a torsion pendulum.
That older device design is known and has been replicated. However a
compass would do the same.

I don't know how patents work in the UK, but in the US a patent requires
full disclosure and reveal of how the device works. If a patent was
granted on it in the US the construction and method of operation must be
revealed. Thus everyone is free to replicate it, no one is free to
profit from it w/o a license.

However, patents are also often issued for things that do not work.
Patent examiners are not perfect. And legally there isn't really
anything wrong with a patent on a non-working invention. It's just not
very profitable.

There's a little too much secrecy here for my liking. For now I will say
it's borderline pathological science. Borderline, but the trend is not
encouraging....
