The idea of storing energy from renewable sources in batteries that are themselves made from renewable sources has certain poetry to it. A wooden battery might deserve an entire poem for itself.
In fact, that battery is more than a fantasy. A team of researchers at the University of Maryland has developed a battery that uses wood – yellow pine, to be precise – as a substrate, reporting that the use of wood fibers avoids major problems that have long plagued some batteries. (more…)
With summer coming to a close, many people are biting their nails over the electric bill because of all the A/C used on those sweltering days. Maybe you’ve considered solar power as an alternative before and were overwhelmed by all the components required to actually set up a system. Where does someone even get started setting up for solar?
Unveiling the Magic
The science of it may seem complicated at first: photovoltaic arrays, AC-DC inverters, photons, etc. When you think about it in terms of everyday life, though, it’s actually quite simple. Everything starts with the sun, which produces light and heat, and that is turned into electricity. Lightbulbs function with the same concept reversed. Electricity causes microscopic particles (known as photons) to escape the atoms and bounce around, which produces light and heat. A solar panel works in the other way, catching these escaped photons that come from the sun, which creates electricity. (more…)
With rising fuel prices, the cost of energy skyrocketing, and our current economic crisis, more and more people are turning to alternative sources of affordable energy. Solar energy is quickly becoming the country’s most prevalent source of power, not only for its efficiency, but also because it is eco-friendly. Through the use of solar panels, the sun’s energy can be harnessed to provide power for a variety of applications – everything from powering your television while camping to powering an entire home.
