Scientists use drones for inexpensive ice prevention on wind turbines

Not unlike the wings of airplanes, the blades of wind turbines need to be kept ice-free in order to function properly. Scientists have now developed an inexpensive method of using drones to apply an eco-friendly anti-icing coating to those blades.Conti… Continue reading Scientists use drones for inexpensive ice prevention on wind turbines

Bill Gates backs novel device promising wind energy at 1/3 the cost

It looks nothing like a typical “fan on a stick” wind turbine, but this oval track with evenly spaced wing blades could be an enormously disruptive addition to the renewable energy mix, since it slashes the cost of wind power to unprecedented lows.Cont… Continue reading Bill Gates backs novel device promising wind energy at 1/3 the cost

Climbing crane shimmies up turbine towers like a kid up a coconut tree

To build or maintain today’s colossal wind turbine towers, you either need an absolute monster of a crane – or something like this. The KoalaLifter self-climbing crane is quick, compact, handles heavy loads and creeps up turbine towers of any height.Co… Continue reading Climbing crane shimmies up turbine towers like a kid up a coconut tree

Extraordinary contra-rotating floating wind turbines to begin testing

A wildly innovative turbine that could halve the cost of offshore wind is set to go into testing in Norway. The 19-m (62-ft), 30-kW, contra-rotating vertical-axis turbine is a prototype of a design that could scale to unprecedented size and power.Conti… Continue reading Extraordinary contra-rotating floating wind turbines to begin testing

Gargantuan 22-MW wind turbine will be among history’s largest machines

The bigger the wind turbine, the better the production and the economics. Hence, they're scaling up to ludicrous proportions.

Imagine something as tall as New York’s Chrysler building, but spinning. China’s Mingyang Smart Energy has announced plans for a colossal 22-megawatt offshore wind turbine, and standing in its presence will be an unprecedented human experience.

Single-bladed floating wind turbine promises half the cost, more power

We haven’t seen a floating offshore wind turbine like this before. Touchwind claims its innovative single-blade turbines will solve several problems to drive down cost and downtime, using a single, huge blade with no fancy active pitch controls.Continu… Continue reading Single-bladed floating wind turbine promises half the cost, more power

Active wind turbine control aims to cut bird deaths by 80%

It’s hard to ascertain how many birds fly into the spinning blades of wind turbines and die as a result – and indeed, the topic is so politically charged that I’d recommend a radiation suit before even googling it. The American Bird Conservancy has wad… Continue reading Active wind turbine control aims to cut bird deaths by 80%
