But this new one by Stanford University is particularly interesting as it's about the 8th largest economy in the world—California—becoming totally clean energy based 35 years from now. The study, published in Energy, concludes Read More...
Cable-less fiber optic design creates connections out of thin air
Radio waves work without cables. So do cell phones and wifi. However we still need wires to transmit light or electricity. That may change. The first experiments with wireless power transmission are being done and now researchers at the University of Maryland have developed a fiber optic laser that Read More...
Phone dock designed to keep chargers out of the landfill
You know how a device’s lifecycle goes: You upgrade every few years and while you might be able to sell your old device, the charger and all it’s accessories go in the trash. In fact, Americans throw away about 100,000 tons of electronics chargers annually. To limit this problem of excessive Read More...
Self-cooling solar cells increase efficiency and lifespan
The biggest hurdle solar cells have to overcome is overheating because converting sunrays to electricity—unsurprisingly—is a very hot process. When solar panels get hot their efficiency dramatically decreases. Engineers from Stanford University have found a solution to this problem by adding a Read More...
New GE startup shows that the time of clean energy fuel cells has come
Fuel cells where invented over a century ago. But apart from the use in space shuttles and space labs, the clean energy technology still awaits a real breakthrough.
