Solar is already a viable alternative to traditional carbon based and nuclear thermal power plants. In 2012, over 31 Gigawatts (GW) of new PV generation went online globally including 3.5GW in the United States alone. In 2013, that number in the United States is expected to grow by 28% to reach 4.9GW.
Inventor Nikola Tesla imagined the technology to transmit energy through thin air almost a century ago, but experimental attempts at the feat have so far resulted in cumbersome devices that only work over very small distances. But now, researchers have demonstrated the feasibility of wireless power transfer using low-frequency magnetic fields over distances much larger than the size of the transmitter and receiver.
It's known that electric vehicles could travel longer distances before needing to charge and more renewable energy could be saved for a rainy day if lithium-sulfur batteries can just overcome a few technical hurdles. Now, a novel design for a critical part of the battery has been shown to significantly extend the technology's lifespan...
