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 [...]
1bog Renewable energy is the buzz word of the year. From the White House to the greenhouse, people are being told that renewable sources of energy, like wind and solar are the answer to the clunky, dirty fossil fuels we've depended on for so long. The federal government is even offering tax credits for building or renovating homes so that they use energy more efficiently. But saying we need homes powered by the sun, and actually heating your morning shower with it are still, unfortunately, two entirely different things.
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.
While listening to the inaugural address today it was hard to miss the nods President Obama made toward the need for alternative energy sources and a shift in behavior towards America’s energy consumption. Happy inauguration day!
Ah, that first cup of coffee in the morning. It really gets you moving. And soon, it could get your car moving, too.
Electric and mechanical power produce heat. That heat, according to research from Oak Ridge National Laboratory (ORNL), could be a ready source of energy — enough to cut U.S. carbon dioxide emissions by 60% by 2030.
Solar, wind, biofuels, tidal power — all green, all sustainable. But they are not the final word in power. In fact, your very words could create power, according to new research out of Texas A&M University.
How long will it take us to get to a truly clean-energy economy? Five years? Ten? Twenty-two? That number might seem arbitrary, but many organizations and scientists see the year 2030 as a reasonable and do-able goal to achieve total clean, renewable energy. Quite a few of those scientists are gathered in Atlanta today for the IEEE [...]
Motion is energy. Capturing that energy is easy if you’re talking about huge turbines. But what about tiny motions, like a footstep? A number of new projects aim to use the energy of human activity and translate it into ways to power the portable devices we so love. The photo above is an obviously early prototype [...]
See end of post for full schematic This ground breaking technology from Cunning Labs could be the most promising alternative energy innovation yet. The system taps into the vast energy potential of the “High Five” to generate electrical energy.
