I must say that is an impressive feat of engineering to achieve an almost useless thing. But I’m pretty sure there are all sorts of different applications where it can be used to stabilize equipment, and things. Actually, with some refinements, if he could get the Pencil to stay absolutely perfectly straight, this could have serious earthquake potential. But I’m talking seriously straight no moving, nothing, and, it would probably be the opposite way actually now that I think of it. The motion table would move, and the motors would try and keep it steady.
Well, either way, it’s impressive.
