Superconductors Could Increase Wind Turbine Efficiency

Benji Jerew — Tue, 08 Jan 2013 17:18:18 +0000

One of the great limitations in any electrical or electronic system is resistance. Electrical resistance, measured in “Ω” or ohms, is not a constant, but dependent on temperature. As the temperature increases, resistance also increases. When considering wind turbine generators, there are limits to the amount of electricity can be generated. The problem is that […]

As they say, details make all the difference when it comes to big things. Following this principle, the huge wind turbines that you see on fields all around the world, need small adjustments and a little intelligence to act efficiently. Called SpiDAR, a newly-developed system can predict where wind is coming from and is going to be a step ahead and over currently-existing monitoring systems.

Makani Power's New Wind Turbine Producing Energy Cheaper Than Coal Plants

Ovidiu Sandru — Fri, 24 Sep 2010 05:56:23 +0000

Makani Power, a company that innovates in the field of wind turbines, has recently received a grant from ARPA-E for developing their Airborne Wind Turbine (AWT), they call Makani M1. Unlike other wind turbines, this one is made of a wing equipped with three small propellers which spin endlessly around its ground anchor point.

$4,500 WindTronics Ultra-Efficient Low Speed Wind Turbine Available This Fall

Ovidiu Sandru — Tue, 09 Jun 2009 19:26:13 +0000

Using big things to create electricity is generally good - but not always. Big things tend to be inefficient, hard to handle and to install. Wind turbines are just the case of this example - if they are too big, they are too noisy and insensitive to slow winds - that leads to inefficiency in all related aspects.

Wind-It: Electrical Towers Transformed into Wind Turbines

Ovidiu Sandru — Wed, 20 May 2009 21:02:54 +0000

This project aims to adapt the current infrastructure of electrical high voltage towers into electricity generating towers. Because they are so tall and well grounded, electrical towers are best for supporting wind turbines (of course, adapted to the towers' shape).
