Single molecule gas detection Graphene makes an excellent sensor due to its 2D structure. The fact that its entire volume is exposed to its surrounding makes it very efficient to detect adsorbed molecules. Molecule detection is indirect: as a gas molecule adsorbs to the surface of graphene, the location of adsorption experiences a local change [...]

With the recent rise in energy costs many people have been looking to alternative sources of energy. One of the greatest energy sources (our sun) is readily available for the taking. We just need to be able to harness it’s power. For those interested, below is a brief history of how solar power came to be.
The history of photovoltaic energy (aka. solar cells) started way back in 1876. William Grylls Adams along with a student of his, Richard Day, discovered that when selen…
Any time the sun is shining, your home’s roof is exposed to solar energy. Why not exploit that energy, reduce your electric bill, and do your part to limit the amount of pollution being added to the atmosphere each day? Mounting photo voltaic cells (PVs) on your roof could very well be a smart way to make your home more energy independent.
A solar panel or cell uses the photoelectric effect to produce electricity. These cells are typically constructed of a thin layer of a …
Conventional resources of power have two main disadvantages over non-conventional resources. One they cause environmental pollution. Second they are expensive. Those are the reasons to convince you for using solar power as far as possible. Home built solar panels save a lot of money as the input is sunlight which comes for free and is available in surplus amount. Home built solar panels can easily be constructed. These are cheap, easy to install and keep the environment clean.
Like all tax incentive schemes, you must read the small print first. Some of these incentives only apply to commercial business solar projects. Of course, you are looking for tax information for projects relating to solar power for homes.
