For me, none.
Any invention has advantages and disadvantages.
Even the catalysts and particle filters of cars are harmful from a point of view (they reduce the terrestrial darkening due to particles :D which accelerates warming :frown: , finally this is the thesis defended by certain labs)

Looping asked:
"When you stir a liquid, do you heat it?"

I learned that there was a system that would allow water to be heated only by mechanical effect, in other words by movement of water.

Anyone know more about this?

For my part, I will ask the person who told me about it to provide me with more information. He works for an environmental education association. He seems to know quite a bit on the subject.
It is perhaps a reverse phenomenon that that which cools the water in a jar.

You have to go to Hydrodynamics. Heating by cavitation.

Thank you jam for your response.
I read diagonally what had written on the effect of cavitation but it seems that for the moment a "heating by cavitation" is not technically developed.
On the other hand, what is written is very interesting and will undoubtedly lead to new discoveries in the future. Moreover, to make the link with a recent comment concerning "the effect of the vacuum", there is perhaps a link between the effect of cavitation and the energy of the vacuum?

Grelinette, if your wind turbine is not very far from the house, I had the same reasoning as you and thought of heating water by friction in a tank. Then I wanted to bring this warm water to the house. All isolated of course, I told myself that even can be efficient without all the expensive processing systems.
It is theoretical because I never went to practice my source of energy was 200m from the house in a land not easy to dig.

Hello Phil53

I am happy to see that I am not the only one with this silly reasoning of saying to myself first that little is better than nothing (especially when it is the result of "a Sunday leisure craft" ), and then simplicity and often synonymous with economic and above all accessibility to more people.

Leonardo da Vinci had said:
"Simplicity is supreme sophistication"

and here are others to ponder:

"Things should be made as simple as possible, but not simpler." - Albert Einstein (1879–1955)

"You can still recognize the truth by its beauty and simplicity." - Richard Feynman (1918–1988)

"Our lives are wasted on details; simplify, simplify." - Henry David Thoreau (1817–1862)

"If you can't just describe it, you can't just use it." - Anonymous

“Simplicity of character is the natural result of deep reflection.” - William Hazlitt

"Simplicity means achieving maximum effect with minimum resources." - Koichi Kawana, botanical garden architect

Good morning all...

1 - I'm new to this forum...

Grelinette wrote:Well ... well ... I think I'm not ready to warm up with my wind turbine! sniff : Cry:



2 - I am continuing a project, one of the first phases of which is to transform the energy of a wind turbine (vertical axis) directly into heat (by friction ... necessarily) and then store it via a fluid.
From what I read on the net, it seems to be the best conversion efficiency of the kinetic energy supplied by a vertical axis wind turbine.
In a first test I am going to test with a hydraulic pump for the lifting platform cylinder .... I will keep you informed of the results ... but you will have to be patient ... the wind turbine is not even started ...

I listen to any advice (advice) or ideas in this area ...
So grelinette, continue your research, and be assured that it interests the world.

wind turbine for direct water heating




by theodric » 25/10/09, 10:55

Hello
I want to encourage you for your research work
I have in fact still in my memory a file on the energy production projects of the late 70s, after the 1st oil shocks: at that time "we" proposed vertical axis wind turbines directly heating a water tank to the Plumbing of the axis, by friction, in the water of the base of the axis on a mass ("roller"): imagine a tank thus fitted out in your home, or nearby if there is noise.
But I have not found the documentation, and since the all electric went through there ...
would you have tracks in this direction, references, indications on the nature of the parts in friction,?
why is an intermediate oil friction tank more efficient?
Bravo for your research in the sense of simplicity!

And why not compress air instead? Because the heat in summer is not very useful ...
