We haven't fished there since, and now spend the early season upriver casting into rushing pools chilled by snowmelt, instead of warmed by turbines.
For regeneration, the still-warm post-turbine fluid is passed through a heat exchanger to pre-heat the fluid just entering the combustion chamber.
At night, when air at ground level is cooler than that found a few dozen meters up, turbulence generated by individual wind turbines stirs warm air downward to heat the surface, the team reports online today in Nature Climate Change.
But beauty lies in the eye of the beholder, and my appraisal of the Longlands Lane turbine on a warm spring evening is not likely to echo that of locals who once knew and loved the empty sky it now fills.
Adopting a controller with parameter updating capability together with using passive structural control techniques such as tuned-mass-dampers may be an effective control design strategy for wind turbines founded in warm permafrost.
Field monitoring data provide evidence of excessive vibration on the wind turbines founded in warm permafrost (referring to soils frozen for more than two consecutive years with a temperature close to its melting point), which was attributed to resonance between the rotor and the tower-foundation system.
It felt a little strange as I drove to the Anclote River Power Plant, my only landmark a belching smokestack on the horizon, where warm water from the plant's turbines presumably attracted all manner of game fish.
Furthermore, the performance of geothermal power plants based on air-cooled Organic Rankine Cycle systems (ORCs) markedly decreases at warm ambient temperatures because of the higher turbine exhaust pressures.
The building will generate its own light from the turbines and heat from stored warm air.
[Sky News] Drawing on readings by sensors aboard a NASA satellite, researchers find that large wind farms slightly increase local temperatures near the ground as the turbines' rotor blades pull down warm air.
