Thermal wind turbine?

[sicetaitsimple]

Regardless of the date of the articles, what counts is the factual content and besides they are not all old!

Obviously not .... An article from the 80s/90s on what can be called "new renewable energies" (solar PV, wind power) is in the vast majority of cases totally obsolete given the progress ( in performance and cost) achieved by these technologies.
PS: as for the "Danish nuclear lobby", you would have to tell us more. Are there nuclear power plants in Denmark?

In the 70s and 80s, and as said in my file, there were nuclear power plants but currently "Denmark imports but does not produce nuclear energy, which is in line with a 1985 law passed by the Danish parliament, prohibiting the production of electricity from nuclear energy in Denmark1,2. In 2014 and 2015, nuclear energy (imported) accounted for 3-4% of electricity consumption in Denmark.

Instead, the country has focused on renewable energy such as wind power to reduce the country's reliance on coal. In 2007, approximately 11,4 TWh of electricity was exported and 10,4 TWh imported. Imports from Sweden amounted to 5 TWh, those from Norway to 3,9 TWh, and those from Germany to 1,5 TWh. Sweden and Germany have a share of nuclear energy in their electricity production3.

As of 2003, three nuclear research reactors at the former Risø National Laboratory have been closed4 and are being dismantled. The reactors were named DR-1, DR-2 and DR-3, and had the following properties5"

As usual false...Three research reactors of less than 10MWth, but no production plants.

I based myself on this source (included in my file):
« It's very classic to nuclear and the gas that the Danish electricity companies proposed to turn to in 1976 to get Denmark out of its almost total dependence on imported oil at the time. »

Admittedly, after research, it therefore seems that all the projects yet voted for the construction of nuclear power plants have failed.

I don't know what was being discussed in Denmark in 1976, I'm just saying that there was never a nuclear power plant in Denmark, and therefore your statement [i]"In the 70s-80s, and as said in my file, there were nuclear power plants" is false. Point.

Thank you for these answers Mr. Baudouin Labrique
Very useful for those who know nothing about this field.

Edit by Rémundo: removal of HS

B. Labrique's professional activities are what they are, but from my point of view that is not the point. And, at least to my knowledge, he doesn't offer to regrow arms with carrot juice?
In short, let's stick to his "summary" document on the "thermal wind turbine" and what revolves around it, in particular the comparisons with other forms of energy conversion, for once we have a subject of character. "technical", try not to spoil it.

There is what Joule did: Joule's machine,

and who intends to manufacture this kind of hypothetical machine?

By reading the file, you could have learned that there were 34 Calorius manufactured:
* " The performance of one of Denmark's first small heat-producing wind turbines was officially tested. [Built in series,] lhe Calorius type 37 – 9 meters high and equipped with a 5 meter diameter rotor – produced 3,5 kilowatts of heat for a wind speed of 11 m/s (strong breeze, Beaufort 6). This is comparable to the heat produced by smaller boilers used for space heating. Between 1993 and 2000, the Danish company Westrup built a total of 34 wind turbines, 17 of which were still in operation in 2012. »

Always the same link that leads to nothing.

I asked bing:

Search for “Calorius type 37”
Message received. I found information about Calorius type 37 on the web page wind-turbine-models.com. The wind turbine type 37 is a production of Calorius, a manufacturer from Denmark. Since year 1993, Calorius is no longer active. The rated power of Calorius type 37 is **3,50 kW**. The rotor diameter of the Calorius type 37 is **5 m**. The rotor area amounts to **19,6 m²**. The wind turbine is equipped with **2 rotor blades**.

And on the site there is nothing about the production of heat ...

Another question :

Search for “wind turbine calorius heat production”

I couldn't find any information about the heat output of the Calorius type 37 wind turbine. However, I found an article on the lowtechmagazine.com site that explains how a mechanical wind turbine with an oversized braking system can be an economical, efficient and sustainable1 heating solution. The article explains that renewable energy is almost entirely devoted to generating electricity. However, the energy we use the most is in the form of heat, which can only be produced indirectly by photovoltaic panels or wind turbines with a fairly low yield. A solar thermal collector makes it possible to avoid the stage of conversion into electricity and thus provides renewable thermal energy in a direct and more efficient way. Moreover, it is much less known that a “mechanical” wind turbine can perform the same function in a windy climate: by oversizing its braking system, a wind turbine can generate a significant amount of direct heat by friction. It is also possible to couple a mechanical wind turbine to a heat pump, which can be less expensive than using a gas boiler or an electric heat pump powered by a wind turbine (wind turbine dedicated to the production of electricity ).1l

The link still broken.
Are you leading us on or what?

Are you leading us on or what?

When you are in the process of "research and development" there are all sorts of processes that are put in place mentally, so seeing a wind turbine on a boat is not so incongruous, on the other hand to see something intentional in a desire to dissimulate is again defamation. .. And I believe that in different aspects you don't have a lesson to teach anyone (if at least you were in good faith and you answered the messages, but overall all your sources are VERY biased (I mean that they have no interest because they are not credible or second-hand)

The wording of the link was correct but for some unknown reason, the page (in French) disappeared from their site (luckily I was able to take extracts
You can see it here by clicking on the first link

So don't take it out on me and throw me "Are you taking us on a boat or what?"

On the other hand I found it here in English (on the same site): https://solar.lowtechmagazine.com/2019/ ... -windmill/ - I made a copy just in case...
