MIT’s new flow battery breathes air to cut costs of renewable energy storage

Wind and solar power are increasingly popular sources for renewable energy. But intermittency issues keep them from connecting widely to the U.S. grid: They require energy-storage systems that, at the cheapest, run about $100 per kilowatt hour and function only in certain locations. Now MIT researchers have developed an “air-breathing” battery that could store electricity … Continue reading “MIT’s new flow battery breathes air to cut costs of renewable energy storage”

A solar cell you can put in the wash

Scientists from RIKEN and the University of Tokyo have developed a new type of ultra-thin photovoltaic device, coated on both sides with stretchable and waterproof films, which can continue to provide electricity from sunlight even after being soaked in water or being stretched and compressed. The work, published in Nature Energy, could open the way to … Continue reading “A solar cell you can put in the wash”

Solar Glasses Generate Solar Power

Organic solar cells are flexible, transparent, and light-weight – and can be manufactured in arbitrary shapes or colors. Thus, they are suitable for a variety of applications that cannot be realized with conventional silicon solar cells. In the Energy Technology journal, researchers from KIT now present sunglasses with colored, semitransparent solar cells applied onto lenses … Continue reading “Solar Glasses Generate Solar Power”

MIT creates Transparent, flexible solar cells using Graphene

Imagine a future in which solar cells are all around us — on windows and walls, cell phones, laptops, and more. A new flexible, transparent solar cell developed at MIT is bringing that future one step closer. The device combines low-cost organic materials with electrodes of graphene, a flexible, transparent material made from inexpensive and … Continue reading “MIT creates Transparent, flexible solar cells using Graphene”

Solar Impulse 2 Completes Historic Trip Around The World Without A Drop Of Fuel

The experimental zero-fuel aircraft, Solar Impulse 2, has completed the final leg of its global circumnavigation attempt. It is the first circumnavigation of the world by a piloted fixed-wing aircraft using only solar power. The Solar Impulse prototype has already set eight world records, including first solar aeroplane to fly through the night, between two … Continue reading “Solar Impulse 2 Completes Historic Trip Around The World Without A Drop Of Fuel”
