inter seasonal storage solar thermal

[lilian07]

I add that we did not look further because the ecology was in no way a problem. Which is potentially like thinking people were stupid before, but AMHA is not.
It is simply that we are above all a society of waste from the air of mechanization and that everything is going well so far.
To return to storage it is true that between theory and practice there is a world and that everything is not achievable in renovation but the spirit of recycling is starting to make its way little by little.
I have cited a few industries with high fatal energy losses, but there is one that would be the champion in all categories and which is already a boiler by design that produces a lot of heat (I am thinking of power plants).
In addition it is a stable heat exchanger in the ground (no variation in climatic conditions nor sensitive to extreme weather variation).
But the devil is probably hiding in the details and I do not know the reason that prevents this type of exchanger.

Certainly. But why aren't all homes in France super-insulated, equipped with condensing boilers or heat pumps, PV on the roof, ... and / or connected to a super-efficient heating network?
There must be one or more reasons?

- You should NEVER piss off the industrialists with severe and changing standards. "When the building goes, everything goes".
- The client must have the impression of getting value for money with cardboard housing.
- With everything nuclear, electricity savings have rarely been up to date.

The reason is that a power plant rejects water at maximum 30 ° C in summer and much less in inter-season. So no chance to significantly recharge a buried seasonal storage, it will certainly even unload it .....

Or it is cogeneration, but there is no longer any need for storage.

- it is sure that if you annoy French founders or cement manufacturers beyond European standards the problem will be quickly resolved .... They will melt or calcine elsewhere. Super result.
- To my knowledge, thermal regulations apply for new constructions.
- Ah, I thought that electricity was expensive?

Not on paper.

ok, indeed 30 ° is not much, I thought that the towers which strongly condense in the atmosphere cooled warmer water.
There is still 75% of thermal losses on a power station which makes a lot of GWh lost in nature.
However, the stable exchanger / cooler function in the soil remains without climatic problems.

More precisely, 66% for an existing French nuclear power plant, 60% for a "modern" coal plant, and less than 45% for such a modern gas plant.
It may be nerd, but it's just physics ...... The will will not be able to do much!

So, if I understand you correctly, is there any way to recover this waste of calories? Am i good?

Cogeneration, trigeneration ...
Guy you can get hot with the loss of power from your PC for example

Ah well, the losses from my PC directly heat the room where my PC is located.
