Casas Em Movimento homes turn to solar

Kitting your house out with solar panels is all well and good, save for the fact that they may spend a good part of the day unable to make the most efficient use of the sun's rays. That is unless your house is inspired by the humble sunflower, which turns and tilts it head to track the movement of the sun.Read More

There's now one mö solar-electric velomobile on the road

Although velomobiles in general are a rather obscure class of vehicle, the human/solar-powered Elf is certainly one of the better-known recent examples. Inspired by its design and performance, Spanish startup evovelo recently put the finishing touches on the prototype of a similar vehicle, known as the mö. Like the Elf, it's propelled by pedal-power and/or an electric motor – and that motor is in turn powered by the sun.Read More


Volta Flyer is made to teach kids about solar-powered flight

Whether they've been crossing the English Channel, traversing the Alps, or attempting to fly around the world, solar-powered planes have been in the news a lot this year. While the aircraft are certainly fascinating and inspiring, there's no way that most of would ever be able to afford one … or is there? If a new Kickstarter campaign is successful, you'll be able to get a Volta Flyer solar airplane for just US$40. The only thing is, it'll be a little on the small side.Read More
