There's an engineering puzzle bugging me and you're likely my smartest contact. Ever heard of a heat engine that works like a hurricane?
I'm thinking a wide cylinder with metal walls, pool of hot water at bottom and cold water flowing above. Maybe solution to OTEC. Thank you!
Hard to make a cylinder with any kind of significant power density with a pressure difference of only a few tens of millibar
However, you can make a balloon float with warm, moist air, so that’s something that you can do with related physics. Warm air balloon
I drew this. Maybe a very flat/wide cylinder like a pancake? Middle matters most, far sides avoid extra friction + max useful surfaces/vol.pic.twitter.com/1P1EE3kolf
See if you can put some numbers to your theory. It may be instructive...
That's where I'm at a loss... but I'll try my best. Thanks for your feedback. I'm still secretly cheering for you and your venture.
