Kitesurfing Hydrofoil Boat Printer Friendly Version
Main features:
* 2-3 kitesurfing type sails
* 2 catamaran hulls
* hydrofoils under both ends of each catamaran hull
* some kind of deck to hold passengers and cargo
Details:
* the kitesails would be staggered from front to farther back (exact locations need to be worked out)
* the angle of attack of the sets of hydrofoil blades on each corner would need to be controllable to facilitate the boat rising out of the water for less drag but not getting tipped over by gusts of wind
* the vertical members that hold the hydroil blades would also act as daggerboards and be steerable to control sideways slipping and enable tacking against the wind
* a small auxiliary energy system would be very helpful for "power steering" and to power onboard computer circuitry and sensors to respond to wind gusts and make rapid adjustments to avoid tipping over
Background
* boats using kites for propulsion date back to 12th century in China (see http://www.kitesurfingnow.com/kitesurfing-facts/history-of-kitesurfing.shtml)
Reward: A lot of free publicity for California State University, Pomona in advertising, literature, web sites, etc. related to commercial sales of products based on this concept.

GPS Shirts & License Plates Printer Friendly Version
I'm sure this has happened to others as well: You're in an unknown neighborhood, basically lost, but there are a few cars, bikes or even pedestrians around who seem to know where THEY are going. If one of them had the same goal as you, you could simply follow them. But then, how would you know...?
Here's where GPS shirts and license plates come to play. The license plate idea is kind of easier to implement: This would be a display beside your actual license plate which is attached to your real GPS in the car, and so the folks behind you can see where you're going.
The shirt would work similarly, with the place you're heading to displayed on the back of the shirt (either automatically via GPS, or to be inserted manually). Of course, it is nice to imagine this idea in an analogous and visual way - nowadays, however, you'd be more likely to implement it virtually: Create an app, have people enter their routes, and off you go.
Reward: One of those.
