Sunny side up: Ford is to reveal its C-Max Energi as “Solar Concept” at the CES. The new PHEV features a so-called „solar concentrator“ that works like a magnifying glass. When parked under this canopy, focused sun-rays hit solar cells in the roof of the vehicle and charge the plug-in hybrid while the car autonomously follows the way of the sun rays. So far, the solar concept is not set for production.

Stability through selectivity: The professors Qiang Zhang and Fei Wei from Tsinghua University in Beijing, China, have developed an ion selective membrane system to make lithium-sulfur batteries more stable. The membrane separates lithium and polysulfide ions, thus suppressing the destructive „shuttle-effect“ on the anode.
