Green transportation also reached for the sky this week as the sun-powered Solar Impulse airplane made its public debut at the Paris Air Show and EADS unveiled plans for an innovative all-electric commercial aircraft. Efficient autos also hit the streets as the Nissan Leaf became the first electric car to tackle Pike's Peak, and we learned that Porsche is working on a new breed of cars that are able to drive themselves. If pedal-powered transportation is more your speed you won't want to miss this beautiful kinetic energy-storing Potenza vehicle, and we were wowed by the solar panel-clad Emax Excalibur hybrid yacht.
In other news, we shined a light on green consumer electronics this week as we brought you a lunar LED light modeled after the moon and Peter Rojas explained how wasteful it is to keep gadgets chargers plugged in as part of our Ask a Tech Geek column. We also shared a low-tech tablet that's perfect for kids, and we showcased a new type of climate-controlled clothing that beats the summer heat. Finally, we were excited to see Sprint launch a contest where you can recycle your old cell to score a Vespa scooter and an eco smartphone, and we brought you seven sustainable designs for a greener Fourth of July.
