Wave Energy Converters: Are They Ready For This Century?

Arsenij Percov — Tue, 24 Jul 2018 10:51:54 +0000

Wave energy converters are always specially designed to ensure that they generate maximum possible electricity from the movement of the waves around them. The design and adaption are made on the basis of data from the past. However, according to Alain Ulazia, lecturer at the UPV/EHU’s Faculty of Engineering, the timescale taken into consideration is […]

Energy Scavenged from Wireless Signals More Efficiently Due to New “Special Materials”

Danny Harper — Wed, 13 Nov 2013 07:52:40 +0000

Think of it as an energy-producing Bug Zapper. But rather than enticing and systematically destroying curious insects, this harvesting device gathers unused wave energy (ala microwave, Wi-Fi, satellite signals) and tunes them for useful applications. While gathering energy in such a manner has been done before, researchers at Duke University’s Pratt School of Engineering have […]

Toshiba Planning Commercial Underwater Ocean Turbines

Ovidiu Sandru — Thu, 01 Dec 2011 20:38:02 +0000

The issue with the various alternative energy sources is that they are intermittent. You can’t trust the sun or the wind to provide a constant power output, and people can do at best is to predict. Ocean currents, on the other hand, are moving steadily, and could provide us with endless amounts of energy while […]

Wing Waves: Harvesting Wave Power By Swinging Beneath The Surface

Ovidiu Sandru — Fri, 03 Dec 2010 09:36:45 +0000

A wave power test plant has been deployed on Nov. 17 two miles offshore of Fort Pierce, Fla., and is now being tested by its designers, researchers from Florida Institute of Technology's College of Engineering. The power plant has been named "Wing Waves," and works by harvesting the elliptical motion of waves 30 to 60 feet deep, and converting it into electricity.

Researchers Use Wind Turbine Technique to Build Efficient Wave Powered Generators

Ovidiu Sandru — Mon, 23 Nov 2009 13:22:21 +0000

Mankind has been adopting the working principles of natural phenomenons and animals since ages. Now, when it's time to learn from fish to develop wave-powered generators, it's also time to learn what others have learned from birds - and use them in the seas, to gather energy which they would later turn into electricity.
