How does a “windmill” without mechanically moving parts work? TU Delft researchers Johan Smit and Dhiradj Djairam developed the EWICON (Electrostatic Windenergy CONvertor), a windenergy convertor that transforms windenergy into electricity without mechanical moving parts. This animation shows how it works and can be deployed.

NXP Semiconductors has developed an innovative, sustainable and highly efficient solar-powered street lighting solution, together with Philips Lighting. The groundbreaking Solar Gen2 solution, demonstrated by NXP at CES 2012, could have a major impact on energy consumption in urban areas at night. By charging street lamps during daylight hours, the new solar-powered solution from Philips Lighting and NXP can supplement the capacity of the conventional electricity grid, saving money and reducing CO2 emissions. http://www.nxp.com/news/press-releases/2012/01/nxp-demonstrates-groundbreakin…
The key to the breakthrough lies in the combination of new High Brightness LEDs and unique patented optics from Philips Lighting, together with NXP’s MPT61x range of configurable ICs for Maximum Power Point Tracking (MPPT), which can deliver 98% power conversion efficiency in solar photovoltaic (PV) cells.

American researchers have created a robotic jellyfish, named Robojelly, which not only exhibits characteristics ideal to use in underwater search and rescue operations, but could, theoretically at least, never run out of energy thanks to it being fuelled by hydrogen.
The video, provided by researchers at the University of Texas at Dallas and Virginia Tech, shows the potential of the robot as it is powered by electricity.
