New York Power Authority may be the first to use "Highway Energy Barriers" -- or wind turbines along the median of motorways, says Omni Magazine. The devices are designed by Thomas Wither, who has worked with engineers from Michigan's Wayne State University to find wind speeds of 10-12 mph for 18 hours daily along freeways. "It's an intriguing concept and we'd like to help him get funding from the Department of Energy," Mark Kapner, manager of the utility's alternative energy programme, told the magazine. "After a prototype-scale demonstration, we'd be interested if this approach compares favourably with other ways of capturing wind energy." The Green institute in Minneapolis also hopes to erect Wither's windmills along a highway in 1996 or 1997, although no official money has been committed. More measurements may be conducted later this year in Michigan.
