As per usual, you have released an interesting and wonderful video on a thing I had no idea about, and now I don't know how I'd never heard of it. This is an incredible system, and I'm so curious as to what else is out there that people like Mr. Olds haven't noticed yet...so much might change when we find it. I can't wait to see more from your channel Tom, and keep finding wonderful things to talk about!,(reply>), Just when you think there is nothing new under the sun someone like Peter Olds decides to reverse a 2000 year old engineering principle, by Archimedes no less!!, and guess what, it works.  And it works in ways that Archimedes hadn't thought of.  Check out some of the Olds Elevator licensees web sites around the world to see some of the most interesting and challenging applications for this truly unique technology.
