California could be powered by 100% clean energy by 2050
There are plenty ambitious renewable energy projects and studies. 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.

The ultimate web resilience: go the cockroach way
Hard to imagine that cockroaches could be an inspiration to innovation? Cockroaches survive in the most difficult circumstances. They can live without air for extended periods of time. They even continue to live—for some time—without their heads. That resilience is the inspiration to a new Read More...
American cars are finally becoming more fuel-efficient
American cars guzzle some 9 million barrels of oil per day. And the American car industry has been notoriously late with implementing fuel-efficiency standards. But faced with a US EPA and Department of Transportation mandate that cars must have an average fuel–efficiency of 54.5 MPG by 2025 the Read More...
Clean energy investments up 33% in second quarter
This line we want to see go up and up. And it has been doing exactly that even during the financial crisis showing that clean, renewable energy is the way of the future. Total clean energy investment in the second quarter topped at $63 billion, which makes it the strongest quarter in the past two Read More...
