Tonight the Lima district of San Borja plans to light an emissions-free Christmas tree in a popular park as part of event called “Magic, Light, and Color: the Energy You Generate.” The 11 meter high tree will display LED Christmas lights powered by a combination of 10 bicycles, a wind turbine, and two small solar panels [...]
The Solar Grove is a highly customizable and efficient system of photovoltaic solar canopies. A Solar Grove installation allows a company to take a parkinglot that is normally an eye sore and a burden on the environment, and use it to harness energy, mitigate the polluting nature of a parking lot and provide an interesting asthetic.
Direct sunlight exactly where you want it, for heating, lighting, or whatever purpose you like. The world’s first computer-controlled heliostat system from Practical Solar reflects the sun's energy into your house for heating and lighting, taking advantage of solar energy that doesn't even directly reach your house. The system can be installed using just hand tools, but the high-tech tracking technology software does the hard work for you, controlling the angle and the focus as the sun moves through the sky, making for an efficient, practical thermal heating setup.
Oh, the things we can learn from nature! Take butterflies, for example. An examination of the microscopic properties of butterfly wings by scientists in China and Japan has led to a new idea in solar cells, one which the scientists say could yield a greater efficiency than most other solar cells on the market.
Is beaming energy from space bound solar satellites the answer to our energy crisis? Harvard Professor and President Emeritas of the National Space Society, Ben Bova seems to think so…
We need to take advantage of the renewable power of the sun… no brainer. How? There are new breakthroughs every week that go beyond tradition solar panels, and WPI researchers announced a great one yesterday: Use the a massive system that we already have collecting rays everyday… roads and parking lots!
