My Modest Solar Setup | Do the Math: "My Modest Solar Setup
Posted on 2012-07-24
I have made repeated references in past posts to the modest off-grid photovoltaic (PV) system I built to cover a large share of our—again modest—electricity usage. By popular demand, I’ll take you on a tour of the system: it’s history, its composition, and adaptation to my house."

Westmill Solar, a 5 megawatt PV farm sited between Swindon and Oxford, is one of the largest arrays in the UK. It was built a year ago to profit from the high feed-in tariffs then available to large PV installations. Adam Twine, the farmer on whose land the 21,000 panels were sited, kept a right to buy back the solar farm from its original financiers. Twine is an enthusiast for community ownership and recently set up a cooperative to purchase the whole array. Small investors can apply to buy shares now, with local residents given priority. If successful, the new cooperative will be the biggest community owned solar farm in the world.

n this Perspective Video, we discuss how the growing world population, the increasing standard of living in many developing countries, the limited supply of fossil fuels, and their adverse effect on the environment, the need for clean and sustainable energy has never been greater. Hydrogen, the simplest and most abundant element in the universe, has the potential to meet this energy need if numerous hurdles in its efficient and safe production, storage, and use in fuel cell vehicles can be overcome. This Perspective briefly discusses the status of hydrogen storage ; past, present, and future. DOI: 10.1021/jz1015372

LED lantern runs on saltwater
LED lantern runs on saltwater
The 1.5 volts of DC power produced by the lantern is enough to run its ten-LED white light, which puts out 55 lumens of light. The lantern also includes a USB port to charge devices at 4.5 volts. The GH-LED10WBW runs for eight hours before the saltwater needs replacing, and the magnesium rod lasts 120 hours.
Marketed as an emergency lantern or for use aboard boats, it’s scheduled to go on sale in mid-September. No price has been announced

Solar-powered oven makes fresh water
Solar-powered oven makes fresh water
Sometimes the simplest ideas are the best. Concerned about the lack of fresh water in the developing world, designer Gabriele Diamanti wanted a solution to desalinate water that was available to households rather than relying on giant, centralized plants. He also wanted it to be something inexpensive that could be made by local craftsman. The result is a ceramic solar still called the Eliodomestico that operates like an “upside-down coffee percolator”.
