The 'Energetic Energies' concept inspires people to think about solar energy in new ways.
Solar panels normally come in two different types. Photovoltaic panels that turn the sun's rays into electrical power, and thermal collectors that heat water using the sun then use it to heat a building or to provide hot water. Now those two technologies are coming together, in a hybrid solar tube that provides the best of both worlds.
A few years back we saw how researchers at MIT were working on ways to generate electricity from grass clippings. Well they must cut the grass a lot up there at MIT, because now another group has figured out a way to make electricity generating solar panels using more of your yard trash.
According to National Geographic, we have 120 quadrillion watts of sunlight hitting Earth all the time. That's a lot of light, folks. This electric plant in Southern Spain is not only really cool looking, but is also a great example of the work being done to harness solar power.
Solar panels are a great technology, yanking free energy out of the air in non-polluting way. But unfortunately, they generally only catch about 15% of the suns rays, making them painfully inefficient. Now a new kind of panel aims to bump that up.
The best gadget designs make you slap your forehead and wonder why you didn't think of it first. That's exactly the case with this solar camera strap, something that would charge your camera by just hanging around your neck while you're out taking pictures.
If a mere 1% of the Sahara Desert were covered in solar panels, enough energy would be generated to power the entire world. That's a lot of potential energy! So it only makes sense that just such a solar field is being built.
I love seeing cool science made real with clever tricks. This pendulum can be started from a standstill, but when out in the sun will start itself swinging back and forth, faster and faster, without being touched.
While it's not the most exciting name, it certainly speaks to the boat's size. Christened the PlanetSolar, the 101 foot by 49 foot yacht is hailed by its designers as the largest solar-powered ship in the world. Either way, we're...
Solar panels are generally big, ugly things that you stick on a building not for beautification purposes, but for ecological purposes. Well, these glass pyramid solar cells help you out on both fronts. Developed by the Center for Architecture Science...
