The generator is called the Electrostatic WInd-energy CONvertor (EWICON) and the prototype looks like it could pass for a piece of public art, with the inner mesh resembling the webbing of a giant tennis racket. The EWICON wind energy generator has no moving parts and is completely silent.
4. Breakthrough lithium-ion battery can recharge 1,000x faster than current tech
Researchers at the University of Illinois at Urbana-Champaign have created a new lithium-ion battery that has pretty incredible power characteristics, at least in the lab.
5. How the giant squid was finally caught on camera
Edith Widder, the scientific mind behind the strategy for finding and filming a giant squid for the first time ever, tells us just how it was accomplished in this fascinating TED talk.
6. 10 ways 3D printers are advancing science
From fish tags and lab supplies to stem cells and lunar bases, the technology is helping scientists do great things.
