Could trees provide another model for wind power generation?
Obviously windmills extract some power from the wind using blades that rotate etc, but I wonder if it would be possible to get energy from the wind by mimicing the rocking swaying motion of trees on a windy day?I believe that larger windmills with a larger area of blade space exposed to the wind will spin with less wind speed. A tree or something like it provides a lot of space for a less powerful wind to push against...so...would it be possible to construct something like a sail on a hinge to extract more power at lower wind speeds? I apologise if this all sounds like nonsense. I m not a scientist, hence the question and I m guessing that windmills work in a way that is more efficient than my oddball suggestion idea.What do you think anyway?Is this nonsensical or impractical?Any thoughts comments appreciated.Thanks
What is the average cost of a wind power generation system for residential purposes?
US wind power generation increases as fossil fuels decrease - a sign of times to come?
The wind energy industry installed over 2,800 megawatts MW of new generating capacity in the first quarter of 2009 double what it installed in the first quarter of 2008.climateprogress.org 2009 04 28 us wind power industry 2800 mw in q more 6153Meanwhile the drop in coal fired generation was the largest absolute fuel specific decline from December 2007 to December 2008 as it fell by 5,198 thousand MWh, or 3 % . Natural gas fired generation was down by 4.4 % and was second only to coal fired generation in its contribution to the national drop in net generation, as it was down by 2,907 thousand MWh from the December 2007 total .Net generation from wind sources was 67.2 % higher than it had been in December 2007.On top of that, as the auto industry continues to close plants, wind energy companies are building facilities and bringing jobs to Michigan.climateprogress.org 2009 04 10 wind turbine plant near detroit to hire 250 wind powe Is this increase in renewable energy production and decrease in fossil fuel use a sign of things to come in the USA?
If solar and wind power generation were judged on 40 year old models?
Like nuclear power is. How would they compare?
Wind power generation, thoughts and opinions on this potential design.?
flodesignwindturbine.org turbine Obviously it is still just in testing stages. However, I am curious if this device could be incorporated in non conventional ways ie. car and or airplane , especially since it seems that a building in my home town is using a similar design in a skyscraperecogeek.org content view 1486 66 Thanks GoofIn regards to perpetual motion, it really wasnt what I was thinking at all. So let me ask this for your brains to chew on.Why is it animals, particularly ones in the sea lakes have bumps on their surfaces fins, trunk . Ordinarily I would presume a smooth suface would be aerodynamic, but that is not the case curse vortices and fluid dynamics . I can think of many cases where adding disturbances actually makes products more aerodynamic golf balls, and that design for a boat that uses two hulls with nothing in the center for example On a final note, I am continually disappointed by immediate dismissal of both new and old subjects, its not scientific in the least either.Discuss
