2W Magnetostriction-Based Vibration Harvester Lights Up 50 LEDs

Following up with a piece of news we wrote about on December 1st, last year, TechOn reports that Toshiyuki Ueno from Kanazawa University has developed a magnetostriction-based energy harvesting device that can produce up to 2 watts of electricity from harvesting vibrations. To be noted that this isn’t piezoelectricity, which we’ve gotten used to lately.

SMES: New Energy Storing Technology by ABB Using Electromagnetic Fields and Superconductivity

ABB, a Swiss-based engineering company, has presented a prototype of their innovative superconducting magnetic energy storage (SMES), at a DOE ARPA-E conference which took place in Washigton D.C. at the beginning of this month. Their 3.3 kWh proof-of-concept SMES is not very cost-effective for the moment, but may one day provide cleaner storage solutions for excess alternative energy.
