Massive skate park for road bicycles Printer Friendly Version
I am always on the lookout for natural half pipes: streets that go down a steep hill and then straight back up another hill. For roadboarding and bicycling, it's my favorite; going up and down, up and down, with minimal effort.
So the idea is to build a massive park, initially one half pipe, that was maybe 100 feet long, 30 feet high. I don't know the physics, but you get the idea, insane speed. Not neccesarily going airborn, just tracing beautiful weightless arcs, 25 feet up, on a well tuned racing

bike.
Analogues of all the various ramps, bowls, rails, jumps, existing in skateparks could be made. And many vehicles could be used, go-karts, road boards, dirt bikes, sleds... The idea could be extended further, skate parks for cars, and that's probably far enough.
A cheap alternative would be for someone to start a website mapping natural half pipes. I know of a lot of mediocre ones, and one ok one in Richland Washington...
Reward: if someone finds a couple acres and some big money for concrete and earth moving equip rentals, I'll get the volunteers together for the labor, and we will all die happy.

Ballista bow Printer Friendly Version
This idea is for a steel torsion spring powered 'ballista' (ancient roman war machine that resembles a crossbow) which fires ballbearings. It could be used for hunting and with such durable ammunition it would be more economical than bows and arrows or firearms. Also would be great fun to shoot at gongs!
Reward: I'd like to shoot one

Tennis glow-dome, or zen-dome Printer Friendly Version
Hardcourt, clay, grass... now introducing the glow-dome. Basically it's a tennis court 'bubble' where the players compete in total darkness. Visual elements such as ball, net, court-lines, tennis apparel (head bands, shoes, etc..) and racquets will glow in the dark. Everything else is not visible. This will offer players a new 'experience' not unlike a vector-based videogame reminiscent of TRON + the added clustophobic element. At this stage I envisage only player participation, as I do not know how to incorporate lines people, umpire, spectators and maintain this 'bubble' condition (everyone would have to be outside the bubble looking in. Plus the type of glazing required to block out total light from the outside).
Reward: watching the russian female players play in their glow-in-the-dark underwear will suffice.
