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.

I built my own Solar Panels for under $100 and a Solar Water Heater for UNDER $10 that are currently powering my 1700 Square Foot home! I used the simple plans at:
Hey, check out my website at ScientificallyGreener(Dot) com and get all the new and improved Equipments to build or buy your own solar and wind energy systems ScientificallyGreener(Dot) com is a website that sells the most modern environmental products available
One person's opinion, and I kind of like it myself since it's so optimistic, is that due to the worldwide recession, the big companies will have trouble buying off the little guy, therefore the little guy will finally be able to flourish instead of giving in to payoffs to feed his family and etc.
That will finally get some of these inventions out to the public so it can see some real progress.
I have seen the other video showing company named 'Nanosolar' running a production thin foil covered with very revolutionary photovoltaic material. This suppose to be third generation of photovoltaic, very sensitive absorbing broad rage of light spectrum photocells. The beauty of this photocells is the falling cost to produce that the 1W of electrical power going down right through $1 level. Suppose to be easy to make, but is nowhere to be seen on the market.

fact is solar power costs 4 times more .
there is no benefit .
