Yeah, that UFO is too caught up in the look. Leaf springs on a camper! But the idea, is the same one a lot of people have had.

That guy is smart and gets a lot done, though I don't think he got this one done.

It is like Gossamer Albatross, not really practical, but it will keep getting re-invented until someone cracks it.

This one already works:
