At PolyPlus, batteries made of lithium and seawater

Batteries made of lithium metal are preferred over lithium ion technology, but because lithium metal reacts with water. But it hasn't really made any sense to try to use it until now. One California-based company called PolyPlus created a lithium-water battery that is making quite a splash. The underlying technology is a bit counter-intuitive, considering lithium reacts violently with water. To get around this though, PolyPlus found a way to protect the lithium metal with a membrane, so the ions could slip through and maintain a charge. ARPA-E director Arun Mjumdar describes the new water battery technology as.. a fish in a glass tank. For demonstration purposes at the ARPA-E conference, PolyPlus put the membrane-covered lithium pack into a glass of water and showed that it could produce enough energy to make an LED light glow. The technology works like this: The battery reacts with the oxygen that is dissolved in water. And you know what? The water battery can produce 1,300 watt-hours per kilogram of electricity, according to Scientific American.

Better Place opened its first European retail station in Copenhagen, Denmark.

Better Place, which offers battery service for electric vehicles, opened today its first European retail station in Copenhagen, Denmark. Better Place stations offer battery swaps for electric vehicles as an alternative to waiting to recharge the batteries. Commercial stations are already running in Israel and Japan. Until now, though, Better Place had only been testing pilot stations in the U.S. and Europe. Most of the stations offer fast-charging plug-in spots for EVs, as well as battery swaps for subscribing members. The battery swap is a convenience for drivers because it takes only a minute to make the switch, according to Better Place. The swapped batteries are then recharged and used in other cars. It takes 15 to 30 minutes to recharge an EV battery pack to 80 percent capacity from a rapid-charging station depending on the vehicle.

SolarEdge Technologies - Solar Inverters, Power Optimizers and PV Monitoring

The SolarEdge PV inverter combines sophisticated digital control technology with efficient power conversion architecture to achieve superior solar power harvesting and best-in-class reliability. The fixed-voltage technology ensures the solar inverter is always working at its optimal input voltage over a wider range of string lengths and regardless of environmental conditions. A proprietary data monitoring receiver has been integrated into the inverter and aggregates the power optimizer performance data from each PV module. This data can be transmitted to the web and accessed via the SolarEdge Monitoring Portal for performance analysis, fault detection and troubleshooting of PV systems.
