Re: Counterproductive environmental measures
You will then explain to me why Augustine or Thomas Aquinas, who could have prematurely made "scientists" like Newton, only sought to rationally demonstrate the existence of God :roll:, or why in the Middle Ages, apart from portrait painters, we have no works of painters other than...

Re: Inter-season water storage "basins" to fight against droughts...
Nothing that Nature has done so far is really valid, everything is in agreement. It just allowed the survival of the human species, while humans want to live, and as best as possible. Nature didn't even invent the wheel, even though it's so practical, what a big loser! By definition the n...

Re: Vortex-effect wind turbines: synthesis
I don't see why we would produce 180 MW of mechanical energy constantly with a tower, whatever it is. Convection or vortex, it's semantic dressing. The vortex is only a special case, a swirling convection. What patents are we talking about exactly? Convection or vortex n...

Re: Vortex-effect wind turbines: synthesis
The civil engineering of all these dizzying structures is systematically problematic, especially since, as already mentioned, the yield is always lower by at least a factor of 2 than the simple installation of photovoltaic panels on the ground. Generally this is true for a typical convection tower system...

Re: Heat storage in sand
Hi, it seems to me that Guy had linked a solar concentration project with energy injection into the subsoil. There is no shortage of patents but in practice it is quite complicated to store such high temperatures over the long term. . Otherwise there are heat pipes or heat pipes, a te...

Re: Vortex-effect wind turbines: synthesis
Synthetic images are beautiful! :mrgreen: If these chimneys are 5000 m high, they are 150 to 200 m in diameter according to the width / height ratio of this model (1 to 30?)... not 10 or 20 m as announced before... You have to be lenient with the video, the objective is to show in the blink of an eye...

Re: Vortex-effect wind turbines: synthesis
Small aside: It's a basic trend on the internet (Facebook effect etc...) which reveals behavioral tendencies (unflattering!) which consist of systematically criticizing in an unconstructed way without having even had a single second. Kindly consult the source (although linked...
