Kite photo from Shutterstock How can we generate more power from renewable sources without using massive plots of land for solar and wind farms? Go fly a kite . According to David Olinger , an associate professor of mechanical engineering at Worcester Polytechnic Institute (WPI), tethered underwater kites could be used to generate large amounts of electricity by harnessing the power of ocean waves and currents. Olinger recently received a three-year, $300,000 grant from the National Science Foundation (NSF) to develop this technology, and work is scheduled to begin in January.

Comments Off on Old-Fashioned Steam Engines Could Solve Solar Energy Storage Problem

Australian engineers might have solved one of the biggest obstacles to scaling up solar energy — the lack of affordable storage technology that allows solar to be used at peak demand after the sun goes down. Their California-based startup Terrajoule is applying an older technology, namely steam engines, to build a storage system that could lower the cost to under $100 per kWh, which is less than 20 percent of what it costs for current battery storage systems. This new system will also last longer (it has a 25 year lifecycle), thereby eliminating use of the toxic and rare materials contained in batteries.

Photo of factory chickens via Shutterstock A study by the UK government’s waste advisory body the Waste & Resources Action Programme (Wrap) reveals that UK households throw away the equivalent of six meals every week. Although avoidable household food waste has been cut by 21 percent to 4.2m tons since 2007, saving consumers almost £13bn a year, up to 24 meals a month and 4.2 million tons of wasted food and drink that could have been consumed goes to landfills instead.
