portable solar charging
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. Continue reading →
Wagan Tech inc has come out with a range of very conveniently sized (pocket-able) solar chargers for consumer electronics. They will charge batteries, iPods, digital cameras etc, all from the sun. The units themselves are very lightweight and come in two distinct types.
Blue Spark Technologies produce printed carbon-zinc batteries, which are small, environmentally friendly and most importantly cheap enough to produce to make them viable. These batteries are also incredibly thin; their standard battery is 750 microns thick (that’s 0.75 of a mm), while their Ultra-Thin series of batteries can go as slim as 500 microns.
