Deer warning system Printer Friendly Version
I live in rural Wisconsin, USA, where there are many white-tailed deer in the woods and fields. Just about every person I know has hit a deer - dangerous to them (and the deer!) and costly, too. The deer have paths that they use.
My idea is to equip cars with gps devices that the driver could activate by pushing a button every time he or she sees a deer. This information would be downloaded to a mapping system (GIS) and then as a person was driving a light would come on every time the driver approached a known deer crossing. The system could become more sophisticated if the display would offer gradations in its display (kind of like the terror alert system) – it would record the frequency of observations compared to the number of times the road was traveled. Although people do not always see the deer, the data might still be useful when the sample size is large enough.
Most people drive the same roads every day to commute, so individuals would quickly develop their own individual maps. However, I also envision what could happen if many people in a community were contributing to a community or state-wide map, allowing a person to drive anywhere in the state and have little warnings when they cross a deer path. The DNR could use the data to track deer populations.
Reward: If someone develops this idea, I would love to be recognized. A free system wouldn't hurt either. Thank you.

Quick change pavement Printer Friendly Version
Roads undergo lots of stress due to the winter/spring freeze-thaw cycle. To help speed up repairs why not alter the chemistry of the asphalt so that it is very flexible? That way large sections of pavement can be rolled up like a giant jellyroll. As the old pavement is wound up and the new pavement is layed down behind it.
Reward: Less traffic congestion and a Timmy's large double-double tea

Rubber band car Printer Friendly Version
As I am interested in any green energy concepts, I am pleased with current developments in hybrid vehicles. I would like to see the hybrid concept grow to include several different energy sources feeding power to one electric engine. This may sound goofy, but one idea I have is to use giant rubber bands as a sort of mechanical battery that could spin a generator that would feed the electric engine of a car. The bands would run beneath the car in long plastic tubes and could be wound with something like a power drill and a system of gears. Current electric cars are handicapped by the size a chemical battery can grow and still be safe and light. This would allow more potential energy to be safely stored and improve milage. While driving, if the battery power dropped to half or so, the rubber bands would be turned on and begin to restore power. If this sounds loopy, keep in mind that a one person glider was recently made that can fly up to two kilometers using a giant rubber band. The best part is that the extra weight is relatively minimal compared to metal parts.
Reward: A free car would be nice, but just making it would be fine!
