New Way Found to Turn Heat Directly Into Electricity
October 2, 2019 | Leave a Comment
Ohio State University scientists have figured out how to capture heat and turn it into electricity. The discovery could create more efficient energy generation from heat in things like car exhaust, interplanetary space probes and industrial processes using a thermoelectric generator. The discovery, published last week in the journal Science Advances, could create more efficient […]

A New Kind of Magnet Found
May 21, 2015 | Leave a Comment
Researchers at Temple University and the University of Maryland has discovered a new class of magnets that expand their volume when placed in a magnetic field and generate negligible amounts of wasteful heat during energy harvesting. The researchers, Harsh Deep Chopra, professor and chair of mechanical engineering at Temple, and Manfred Wuttig, professor of materials […]

The Very Best Magnets Could Be Cheaper
April 28, 2015 | 1 Comment
Researchers at the Ames Laboratory have used cerium, a widely available and inexpensive rare-earth metal, to create a high-performance magnet that’s similar in performance to traditional dysprosium containing magnets that could make wind turbines and other generator and motor sets less expensive to manufacture. Karl A. Gschneidner and fellow scientists at the U.S. Department of […]

Europe Awakens to the Rare Earth Metal Shortage
February 18, 2014 | Leave a Comment
The European Union has begun to gather concern about the availability of rare earth elements. The rare earth elements are important components in green energy products such as wind turbines and efficient automobiles. The demand for metals such as neodymium (Nd) and dysprosium (Dy) is increasing much faster than production. These metals are used in […]

High Efficiency Electric Motor Freed of Rare Earth Elements
April 16, 2012 | 4 Comments
Both U.S. and Japanese news services have picked up the announcement that Hitachi has developed a high-efficiency 11 kW (About 14.75 hpe) permanent magnet synchronous motor without using the rare earths neodymium and dysprosium. The announcement has the new 11 kW motor’s efficiency rated at about 93% and running at the highest of the International […]
