Researchers from the Massachusetts Institute of Technology (MIT) have announced a new power generating device that is able to use temperature fluctuations to create electricity. The technology is based on principals of thermoelectric devices able to generate power when one side of the device is a different temperature than the other. The device the MIT team has created doesn't require two different temperature inputs at the same time, rather this device harnesses changes in ambient temperature to create electric power as a virtually perpetual renewable energy source. MIT's Thermal Resonator - Virtually Infinite Power Source? The new system is called a thermal resonator and has the potential for... Read more...
Well here’s one: MIT researchers are developing a way to harvest energy from, off all things, water droplets. They discovered that when water droplets spontaneously “jump” away from a superhydrophobic surface, they generate a tiny electric charge. Condensation is the real mechanism for the movement of the water, and the team figured out that by using interleaved metal plates--particularly when adjacent plates have opposite charges--they could gather that energy and send it through an external circuit, thus powering small electronic devices. This machine harvests energy from water droplets What’s really cool about the whole thing is that it’s a passive process, meaning... Read more...
Google is kind of involved in everything, and the company is tackling clean energy with gusto, too. In conjunction with a White House push for renewable energy and agreements from some 300 organizations to pursue clean energy options that includes 1 billion square feet of buildings in the U.S. (and a $2 billion investment in making federal buildings more energy efficient), Google announced that it’s created the Little Box Challenge to foster clean energy innovation. Specifically, the company will pony up $1 million for whoever comes up with the best (that is, smallest, cheapest, and most effective) power inverter. Shrinking the size and cost of power inverters will mean that solar installations... Read more...
Google is officially a technology empire, as it expands its domain into an ever-increasing number of markets. The latest area that Google is toying with is renewable energy, as the company has acquired Makani Power, a company that Google has apparently been investing in since 2007. To be more specific, the wing of Google that bought Makani Power is the somewhat mysterious Google X lab (birthplace of Google Glass), which is Google’s moonshot think tank and makes the acquisition all the more intriguing. Makani Power makes autonomous unmanned wind turbine aircraft that are tethered to a terrestrial source--in other words, kite power. The company has just recently been making successful flights...
