Cars

Ultra light weight, alternative power versions of todays cars:

First, Cars kill more people than anything else. Period. Between 50,000 and 60,000 each year just in the USA. 911 was ~3,000. Big deal.  In Y2K, it was estimated that the Economic Cost of Traffic Crashes was over $630 Billion USD.

• http://www.didik.com/criticalev.htm Very good overview / FAQ on electric vehicles. One critical passage (which I hope I can quote here without offending the author) is: "These batteries weigh more then normal car batteries and are designed to endure up to 2000 charges. Under normal conditions, this translates to about two years of use. A set of eight deep cycle batteries can cost as little as $800. When the cost of replacing the batteries and the cost to recharge the batteries are considered, the cost to run a small electric car (non-hybrid) is about three times more than a conventional economy gasoline car. Since the cost of electricity tends to more or less follow the cost of fuel, it is unlikely that this ratio will change in the future. Electric cars are fun to have and drive, but you will not save money, nor will you really help the environment." The page then goes on to discuss how best to build an electric anyway.

• http://www.sunfrost.com/batteryless_car.html Using a 150 farad capacitor in place of a battery to start a standard gas engine (Ford truck in this case) "The capacitor does self-discharge after several days, however, it is easy to keep fully charged with a very small solar panel (about six inches square) even when parked in the shade. A major advantage of the capacitor as a starting device is its potentially long life and its use of more environmentally benign materials as the capacitor contains no lead. The principal ingredients inside the steel case of the capacitor are activated carbon and potassium hydroxide. This mixture could be easily neutralized by a weak acid such as vinegar."
• http://www.eere.energy.gov/afdc/fuels/electricity_laws.html "Many federal and state incentives encourage the use of electricity as an alternative fuel. Select a state below to view electricity-related incentives and laws in that state." For example, the state of California may give you up to $5,000 if you purchase an electic car...
