Good to know: no time travel.

Indeed, but it isn't that hard to get 1.21 gigawatts of power either. All you need is an 80" OD cylinder with 1" walls that weighs 120lbs and spin it up to a measly ten million rpm. The cylinder is then storing about 10 gigajoules of energy... just deliver that energy in the right time and you have 1.21 gigawatts of power... By an amazing coincidence that flywheel seems to follow the weight limit and <R16> rules; I had better get working on this, don't want to get left in the future.

There's also the theory that the mechanics of time travel would erase any knowledge you may posses about the future, sorta like a cosmic safety switch to prevent paradoxes...

Oh, and don't forget, only living organic material would survive the journey, so you'd better not travel to nationals... It'd be pretty embarrassing to show up in the middle of the finals on the overpass stark naked...

Good luck to you with this project. You're going to need it.

Besides the obvious challenges of accelerating, stabilizing, and recovering energy from this 80" hula-hoop-of-death, you'll need to find a material that can withstand the hoop stress without flying apart .

Also, since the surface of your hoop will be cooking along at a just over one meter per microsecond, you'll need to refigure your energy calcs to account for special relativity. That speed is significant with respect to c.

Assuming you overcome all of the challenges, please don't present this device for inspection at a FIRST event -- good volunteers are hard enough to find without having to worry that one of our inspectors might fall into a wormhole.
