A new alloy with unique properties can convert heat directly into electricity, according to researchers at the University of Minnesota. The alloy, a multiferroic composite of nickel, cobalt, manganese and tin, can be either non-magnetic and highly magnetic, depending on its temperature.
The federal government is investing in a one-of-a-kind power-storage plant in New York that will use a network of flywheels to store energy.
Massachussetts-based Beacon Power says the plant will buffer 20 megawatts of power on the grid, according to CNET. That's a big jump from previous installations, which have provided about a megawatt of power.
