Wow, that sub is actually pretty cool!
The merry-go-round rowing machine, install them in prisons with generators and inmates can produce and store needed electricity for the prison. no sitting around. it's not inhumane or torturous.
I guess you steer it by shifting the center of mass...
I like the personal sub!
The bike sail however, is pretty dumb. We did the same thing with a windbreaker and a skateboard when we were kids. It would be fine set exactly square to a tailwind, but go the other direction and you have a fantastic speed brake, lol. A strong crosswind would probably jerk a rider right off the bike.
The dynasphere would make great toy if one had a big field to roll around.
Those glasses would be perfect for me...
