Gym attendance by the average person wastes energy in multiple ways. Fuel is required to drive to the gym, and the gym machines sometimes require electricity. Imagine if you could go to a gym where much of the fuel and electricity usage mentioned above could be offset while exercising on the … [continued]
Foreign idea, eh? (Cleantech to help people.) In another GE video focused on solutions from the bottom up, here’s an inspiring video about 4 young teenagers who put in a ton of time to develop a technology that could help people around the world. Whether their technology is better than … [continued]
I remember when I powered a small electric motor with heat (and a good amount of it) using a thermoelectric module. However, I had a hard time achieving more than 1 volt. A 15-year-old girl in tenth grade from Victoria, British Columbia, Canada recently got around this problem using a circuit … [continued]
What exactly is a watt? Can you feel it? If you remember from your last physics class, you could say it is a unit of power, one Joule per second, or a rate of energy usage. All of these answers are correct, of course, but what do they mean? How … [continued]
Grease that pompadour and lace up your platform shoes because it’s time to shake your groove thang for renewable energy. Michel Smit has come up with the energized dance floor that transfers your fancy footwork into electricity. As explained in the video, repeated movement on the floor activates a generator, … [continued]
The Southeastern Pennsylvania Transportation Authority announced last week the unveiling of what they are terming as a “ground-breaking recycled energy and optimization project.” The pilot project captures the braking energy of its trains on the Market-Frankford Line and integrates the captured energy into the regional electric grid. This is a unique … [continued]
24-year-old Anthony Mutua has created a device that turns your sneakers into cell phone chargers. The invention is being presented at Kenyan Science Technology and Innovation Week in Nairobi this week. “The shoe apparently has a very thin ‘crystal chip,’ perhaps a piezoelectric device, that generates power when the sole bends. … [continued]
Commuter trains run by SEPTA, the Southeastern Pennsylvania Transportation Authority, are becoming “virtual power generators” thanks to new technology that captures the energy from braking and feeds it back to the grid. CleanTechnica first reported on the regenerative braking system when it was in development a couple of years … [continued]
The nPower® PEG is a new “backup battery charger for hand-held electronics that uses the energy you generate while walking, running, or biking.” It can be used to power you iPod, cell phone, etc. What do you need to do to make this thing work? Not much — just stick it … [continued]
Think about this: when airplanes land, there is some pretty serious energy lost as the plane brakes and slows down. We already have electric vehicles, trains, buses, shipping trucks, garbage trucks, and more saving energy from such braking and using it later for power. Why not planes? An Airbus 320, … [continued]
