Sandia innovation eliminates reliance on rare-earth magnets for large-scale wind turbines

Green Car Congress

Motivated by the need to eliminate expensive rare-earth magnets in utility-scale direct-drive wind turbines, Sandia National Laboratories researchers have developed a fundamentally new type of rotary electrical contact. Most of the current utility-scale wind turbines are dependent on rare-earth magnets, Koplow said. 1 milliohm).

Study suggests arrays of closely-spaced counter-rotating vertical-axis wind turbines could enhance power density of wind farms by up to an order of magnitude

Green Car Congress

Dabiri suggests using optimized arrays of smaller vertical-axis wind turbines to increase the power density and reduce the cost, and visual, acoustic, radar and environmental impacts, of wind farms using giant horizontal-axis turbines. constraint limits the amount of power that can be extracted from a given wind farm footprint.
