The Air Car. A car that runs on compressed air. While not a new idea, or unique, the MDI car can reach a speed of 68 mph and has a claimed range of roughly 124 miles. To recharge the tank, the car reportedly needs to be plugged into the grid for 3 to 4 hours or attached to an air pump in a gas station for only 2 minutes. Is the wind of the future about to break? Will this technology pass gas as our urban fuel of choice?

The end of the light bulb? E. Fred Schubert, a professor at Rensselaer Polytechnic Institute "claims to have invented a 99-percent efficient reflector that promises to speed the replacement of light bulbs with LEDs." According to researchers, this could happen within the next five years. The current prototype is bankrolled by the ARPA and The National Science Foundation "recently award Schubert's team a $210,000 grant to create in three years a commercial version of his patented omnidirectional reflector."

"Schubert claimed that lighting accounts for 25 percent of U.S. electrical energy consumption. Since white LEDs emit more light per dollar and generate less unwanted heat, they are potentially a major energy saver." (see EE Times link)

Meanwhile, some of the oldtimers seem to be pretty refractory.
