Their entry at the Companies Registration Office is
here but says little of interest.
Orbo reminds me of a package that arrived on my desk (since I was the most junior member of the team) with a demand (more like a threat, really) that we at the Central Electricity Research Laboratory examine it.
The report it contained was 12 pages of hand-written screed, the graphs were hand-drawn in felt-tip marker pen without even the aid of a straightedge, and the letter threatened to take the idea to our competitors if we didn't take it up immediately.
I took the VHS tape home and watched it. It showed a small wheel with magnets on its rim with another rotating ring of magnets around that. Not dissimilar to Orbo.
To this day, I have no idea what the author was on about. I only assume that it was a concept for a perpetual motion machine. I do remember him complaining that science was a dogma-filled religion, something McCarthy has also claimed.
