Spray-On Solar-Power Cells Are True Breakthrough
Posted by admin on Jul 30, 2010
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.

Can you give me interesting information on solar energy/power?
Posted by admin on Jul 30, 2010
It might help me to make my project more interesting and fun.
well…what exactly is your project? solar power=cheap, free, and easy. you could make a solar powered hotdog cooker to show how easily it can be harnessed.

How much does it cost to get a solar power panel?
Posted by admin on Jul 30, 2010
I’m thinking about getting one, and I just wanted to know how much it costs.
depends quatity, type, malfurure, size, are you handy or not i saw are www.fuelless.com you can make a couple KW for $100. ebay has solar
cells you can assemble for $40 so sorry if this is not what you are looking for.
What would be the Right’s reaction to an a tragic accident involving solar or wind power?
Posted by admin on Jul 30, 2010
If there was an accident resulting in deaths at a factory manufacturing solar panels or wind technology, do you think Fox News and Rush Limbaugh would cover it differently than tragic accidents involving coal mining or the petroleum industry?
SEAN: Having worked in solar panel manufacturing for quite a while now, I can tell there are plenty of hazards. Exposure to poison gases and chemicals, electric shock, fire, lasers, robotics, annealed glass to name a few.
JACKASSHOLE: Have you ever heard of windmills? They’re still in use today.
I’m sure they’d love to point out that they’re not exactly safe, either, and use it to point out that any sort of technology covers some dangers, thus let’s keep using coal/oil/nuclear. But I doublt they’d seriously say ‘lets ban solar, the sun’s just too hot to handle safely!’
Where can I buy a solar powered car?
Posted by admin on Jul 30, 2010
I’m looking for one that’s solar, legal, and doesn’t look stupid. I’ve seen them on the links below but nowhere to order any. Also, how much are they? (don’t say"very expensive")
Awesome Car Right Here —-> http://www.aboutmyplanet.com/alternative-energy/solar/facts-solar-powered/

P.S. I don’t care about the speed as long as it goes faster than people walk.
They do not yet exist in the market. No car that could only go 30 MPH could be licensed for the public roads.
Wind Generator and Solar Panel – Build Your Own Portable Wind Generator at a Low Cost!

http://www.WindEnergyGuide.net – Wind Generator and Solar Panel – Build Your Own Portable Wind Generator at a Low Cost!
Are you someone who is searching for a place where you can buy a portable wind generator at an inexpensive price? If so, there is no better deal you will find than building your own with the help of an easy to follow DIY generator. This article will not only help you to see how cost effective it is in building your own portable wind generator, but how simple and easy the process is.
The cost of buying a wind generator can be in excess of $500 which is often the price range for units with smaller electricity output. Larger units go for twice that price and above, depending on the amount of electricity they are able to produce. But for under $200, you can build your own generator that is capable of generating the same amount of electricity as readymade versions. This can all be made possible, by following one of the many DIY wind generator guides that can be purchased online.
Any of these DIY guides should be able to show you how you can create your own wind generator from parts that you probably already have around your home. For those parts that cannot be found at your home, you should be able to find them at electronic stores and hardware stores at reasonable prices. And there is no need to worry that the task of building the generator might be too challenging and time consuming. Most DIY guide uses the help of illustrated diagrams to guide you step-by-step through the entire process, which makes it possible for people of any level to follow.
Components needed for building a portable wind Generator:
DC Motor – This is the most important component that will be required, as a DC motor is what is needed to generate electricity from the rotation of the blade of the the generator.
Electricity inverter – This is necessary, because the electricity that is generated by the wind generator is DC, while most appliances require AC power to work. So an inverter will convert the electricity to AC — making it possible for the generator to power up various appliances.
Automotive battery – A decent size battery will be required to store the energy being generated by the portable wind generator. It can be a new or a used battery, but should be good enough to retain sufficient charge and help also to regulate the electricity flow.
There are other components that will be needed, but the one that were mentioned above are those you will most likely have to buy. The others can possibly be obtained from around your home, as the DIY wind generator guide will explain to you in full.
As you can see, there is no need to over spend on buying a portable wind generator, when you can build your own with the help of a do-it- yourself guide that can be purchased online at a reasonable cost.
