Yes, I did read Eric's comments. My kids had big wheels and wore out the plastic wheels riding them. And Eric's super-springy downhill racing bubbles sound like a ton of fun!
Did you by any chance see my story about the "Giant Running Robot" Man-Amplifier? I'm sure Eric would like that one, too! ;)
I have a design for a lunar racer that I intend, God willing, to one day write about here on Steemit... How about a race around the Moon?
I missed that article before, but just checked it out. Pretty amazing stuff. The human imagination is unbridled, that's for sure. I think someone made a bubble like Eric talks about. Some sort of thing with a gyroscopic seat. That would be a downhill trip! Let me know when you post about the Lunar racer. Sounds pretty cool.
I will try to remember to let you know!
I "invented" the concept many years ago when Omni magazine ran a contest. I'm hoping to relocate my original 300-word write-up describing it. :)
I know how that remember stuff goes...amazing you have an invention. Maybe I'll see it some time through my telescope ( :
