In the Betz hypothesis (non-ducted wind turbine), part of the air can escape by bypassing the area traversed by the blades; which is not the case in the hypothesis of a ducted vertical flow with controlled overpressure. So yes, we are getting closer here to the problem of gas turbines (b ...

Does anyone have news of Mr Coustou and his project ??? Hello to Sen-No-SEN and to all of you, I had many concerns (health and financial) and still some disappointments in contacts that looked promising, but which my interlocutors recoiled before the importance of. ..

+1 with Maloche ... But hey would already need a real prototype in real life ... to have a chance to convince them ... it can take years or even decades given the stakes and the inertia ... I hope that we will not have to wait for decades, given the contacts currently underway in Gironde, departing ...

It is true that when reinforcing a power plant, behind the turbines, there is still a bundle of calories to recover. It would suffice to replace the cooling towers perfectly. A nuclear power station currently balances 2/3 of the heat released by reactors in nature. The towers ...

Hello, This is very interesting, and what would be the daily / monthly / annual production of such towers? Nighttime operation? Investment / production ratio? Comparison with wind turbines? All the answers are on my site http://groups.msn.com/ToursAerogeneratrices2/ Alain

Negotiations (arduous) underway with two companies and institutions. So far no official help, only verbal encouragement. No contact with universities or labs: Alary and I developed everything on our own, with only the advice of three engineers ...

I think I can avoid or limit this risk. At the turbine outlet, the flaring of the top of the structure produces a certain expansion of the air. The frustoconical fairing constitutes at this level a cold surface on which some of the moisture will condense. Pure recoverable water ... The rest ...

Remember that wind turbine towers are not conventional solar towers. They combine all the possible natural forces and effects (plus, if possible, low calorie recovery) in a unique structure optimized for this purpose. In addition, open peripheral shutters ...

You can also try to use the fan (or other blades) by building a streamlined flow wind turbine. If the air duct is tapered, we can even benefit from the Venturi effect. This effect will concentrate the energy of the wind on a smaller surface (that of the fan) while accelerating it. I don't ...

technical question: is the performance better if: 1) there are no covers so there is additional water vapor that rises in the tower, and despite the energy consumption to evaporate this water ( around 540 calories / g), water vapor being lighter than dry air, the result ...
