There are 2.7 million miles of public roads in the United States, and in the past we’ve seen several innovative designs that transform these paved surfaces into energy and heat-generating solar roads. One company, Solar Roadways, has even come up with a prototype solar panel for roads, however they are expensive ($7,000 each) and it […]

23 Year Old Invents Solar-Power Fridge Being Used In Africa
23 year old Emily Cummins has invented a solar-powered fridge currently being used in Africa. It uses zero electricity to keep the contents at 43 degrees. Isn’t it amazing what some people do?
U.S. Subways Harness Kinetic Power To Recycle Train Energy
PHILADELPHIA — For years, subway cars have been able to recycle some of the energy created when they brake, turning it into electricity to help power the train or others running on the rails at the same time. The problem is it’s a short-term benefit, with much of the energy wasted by the time the […]
Massive Lunar Solar Power Tower Beams Energy to Earth
This massive astral power tower just won the 2010 Moon Capital International Design Challenge. Designed by Bryna Anderson, a graduate student from Columbia University, the concept is based on American physicist Dr. David Criswell’s proposal for a Lunar Solar Power System. It works by collecting energy on the lunar surface using photovoltaic converters and then […]
Solar Energy Gains Steam—or Rather, Hydrogen
Solar power is arguably the cleanest energy source there is. But it’s also relatively inefficient—arguable from a technical standpoint, perhaps, but certainly not from a practical one. That can soon change. A new Atlantic report says that inventor Lonnie Johnson may have figured out how to turn solar heat into electricity with twice the efficiency […]
Solar Power Myths
Solar power myth busting I’ve been working in the renewable energy industry for a couple of years now and while I’m still by no means a technical expert, I’ve picked up a decent working knowledge along the way. In the time I’ve spent talking with people about solar power, the same sort of myths and […]
Worm Composting
Worm composting is a process where earthworms are used to process waste materials into a valuable organic fertilizer. It can be done on a large commercial scale – there are farms that produce thousands of tons a month of worm castings – or in a small worm composting bin in your garage or garden. Although […]
