Wind Already Powers Some 2.5 Million U.S. Homes
Wind is the fastest growing energy source in the world...and here in the US wind farms have popped up in more than 30 states, producing enough energy to power an estimated 2.5 million homes a day. Thanks to growing concerns over natural gas prices, a desire for energy independence and incentives for renewable energy production, it's expected this trend will continue.
A clean, renewable energy source, wind energy systems generate no water or air emissions. While critics of wind power point to a price discrepancy, noting that construction costs for wind-powered generators can run double those of fossil fuel plants, supporters counter that once wind facilities are constructed, there are no fuel costs, because wind, of course, is free. Likewise, they say that since maintenance is considered minimal, wind-power costs are competitive.
Experts say it's relatively easy to harness the energy in wind- essentially you put a rotor on top of a tall tower, the wind blows the rotor, which is connected to a shaft, which drives an electrical generator to produce electricity.
The American Wind Energy Association forecasts 6 percent of all homeowners in the U.S. will receive their electricity from wind by 2020.

Shawn Frayne invented an inexpensive non turbine wind generator called the wind belt. I have no specs other than what you see on the video. I imagine it's use on the roof of an electric car but obviously it can be used anywhere there is wind. The bennefit is that it is very inexpensive to build as opposed to a standard turbine wind generator.
The fan simulates the wind which moves the belt which moves the magnets through the coils to make electricity to power the clock and LEDs. I don't know how much the output voltage is.

SOLAR REVOLUTION - Solar Paint
Ted Sargent is a pioneer in solar science. He's working on solar technology that could literally be woven into every aspect of daily life, from our clothes to our roads, using what is known as a spray-on solar cell. The implications for our energy systems are profound. As Ted says, "Solar energy is not just an exciting science problem, but an incredibly important human problem."
Ted is working on solar nanotechnology with the potential to make solar energy very cheap and allow society to collect it on a huge scale. Currently, solar technology costs more to build and install than most people are willing to pay. Solar panels, for example, the technology most commonly associated with solar energy, are installed on your rooftop. The cost of collecting one kilowatt per hour of solar energy (about a third of the electricity an average household uses on any given day) is about $11,000.
Not only are panels expensive to install, they capture only the visible portion of the sun's rays so they work only on sunny days. Ted's focus is the infrared portion of the sun's rays which accounts for more than half of all solar energy. What's more, infrared energy is available to us even in cloudy weather.
A quantum dot is a semiconductor nanostructure that confines the motion of conduction band electrons, valence band holes, or excitons (bound pairs of conduction band electrons and valence band holes) in all three spatial directions. The confinement can be due to electrostatic potentials (generated by external electrodes, doping, strain, impurities), the presence of an interface between different semiconductor materials (e.g. in core-shell nanocrystal systems), the presence of the semiconductor surface (e.g. semiconductor nanocrystal), or a combination of these. A quantum dot has a discrete quantized energy spectrum. The corresponding wave functions are spatially localized within the quantum dot, but extend over many periods of the crystal lattice. A quantum dot contains a small finite number (of the order of 1-100) of conduction band electrons, valence band holes, or excitons, i.e., a finite number of elementary electric charges.
