Spray-On Solar-Power Cells Are True Breakthrough

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 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

Custom hybrid electric solar power bike build – Hybrid electric vehicle/scooters/ebike/EV with solar technology riding around squamish, BC Canada Summer 2011 Version 2.0 Lighter, Faster, Safer +GPS-WiFi-3G . . . . . & even more Solar Power ! Visit www.thekpv.com THEKPV bike build began in 2008 by Terry Hope. He had worked as an engineer aboard Copper Sky. An 88ft steel haul sailboat. The captain would not allow a full size electric scooter or bike.. Terry had only one option.. design a custom electric vehicle kit that would fit inside a suitcase. THEKPV ebike/e-scooter kit specifications 44 lbs without solar panels 396 Wh Battery / main 13 km Range / minimum 15 min recharge 80% / AC power 28 Wh 12v booster pack 10000 cycles / lifetime charges 10.8V Capacitor / booster 50 lbs with solar array 50 Watts solar power 12V Kinetic generator device THEKPV ebike build features many custom parts from a generator that charges a capacitor bank with a flip of a switch mounted on the scooters handlebars beside the throttle grip. Onboard solar power can charge any 2 cells/caps at one time via 4 rocker switches. Each of the booster packs are turned on/off via another group of rocker switches mounted on the scooters handle bars opposite the throttle, and when turned on power the electric motor directly combined with the throttle output from the controller.

Next Generation of Cheap Solar Cells

****Since all the comments seem to be either 100% positive or 100% negative about this solar technology i would like to clear up some some misconceptions. First of all I’d imagine that takes years to set up the the precision equipment for 2 of the largest solar panel manufacturing plants in the world and be able to print solar photo cells as fast as newspaper. After the plant was completed in 2007 the first focus was on commercial uses and their first costumers where municipal utility companies. This sounds to me like a good business tactic to help you establish a successful business from the start. Next they started offering it to electrical contractors as part of a beta testing process so they can work out the kinks that arise from scaling down their panels from large commercial ones to the ones that you can use on your house. That is where were at today. After the beta testing they will start offering them to the general public. Their website even has a place to enter your email address to be notified when this technology will be available to you the home owner. Its a process and that apparently some people out there believe happens over night. This company immediately got more financial backing then needed. Google is one of the biggest investors so I believe its all legitimate. There are two benefits from the use of alternative energy. It will save you money but also it means that energy produced is done so with out creating pollution. This is good for everybody. Even

The PS10 Tower: The Future of Energy Generation?

Just outside of the city of Seville in Spain, one can see a monolith that largely resembles something from the Lord of the Rings. A huge, towering eye stands a 115 meter high tower, looking out over a sea of large, shiny reflective objects. To the innocent bystander it is an odd, or even alarming sight, but what is happening in this small corner of Spain could indeed be the future of energy.

The monolith is in fact a PS10 tower, a technical name for what is essentially a huge solar panel. Like many solar panels, it gathers the sun’s heat and boils water to create steam; this, in turn, creates electricity, which can then be used to power anything from a small town to the oven in your kitchen.

What makes the PS10 Tower different, however, is that it does not just receive sunlight directly from the sun. While it would be effective in doing so, the PS10 Tower looks out over 624 movable mirrors, known as heliostats, all of which are positioned to shine the sun’s rays directly onto the solar panels atop the tower.

If it sounds complicated, that’s because it is – but essentially, what the PS10 Tower generates in power which then becomes electricity is 624 times more powerful than your average solar panel. Thanks to the heliostats bouncing the sun’s rays directly on to its receiving panels, the PS10 is able to create steam to drive a generator at a rate previously unheard of for solar technology.

What’s more, the experiment has proved so successful that a second tower and second bed of heliostats – the PS20 Tower – has now been built. The Spanish have capitalized on their natural resource – blinding sunlight – and used it to create electricity. Even more excitingly, it works. So is are the PS10 and PS20 towers the future of solar energy? They just might be.
