Ditto for anaerobic digestion !!!

Nothing is easier than storing methane, at a low additional cost.

And to "let go" of the mechanical horses during consumption peaks (at an additional cost for the investment on the group) ...

On condition of paying a little more for this "peak" electricity, it would be easy to adapt the anaerobic digestion stations as soon as they are built. And to value the fact that luckily, energy is easily stored!

During this time, millions of very expensive experimental stations are being built to store solar energy (salt fusion, etc.).

It seems to me that we always manage like idiots what should be "SMART GRID"! [for those who are not English speaking: smart = elegant, intelligent ... Hence my emot game with "con"]

This is no reason to write such rude bullshit!

I quote, so that we can see the absurdity! I underline.


Thus compared to a conventional gas boiler, you'll be able save 45% electricity and 25% gas, or financially, an annual gain of around 500 euros for an old detached house of 160 square meters.


Even Jesus was content to multiply the loaves and walk on the water! There, we create energy and we walk on the head?

This alone is yet another demonstration:
store solar energy (salt fusion, etc ...).


because to store the solar heat of the day for the night or of summer for the winter underground, it free, is much less expensive than the molten salts (factor 1000 to the m3) !!

To heat for free in winter with summer heat, it has been working since 2007, with good efficiency, at:
www.dlsc.ca

All its heating per year saved entirely, with a system much more wear-free than a cogeneration boiler, which also can be used in addition to the free wood in excess, which I leave or see rotting!

and we can store inexpensively underground solar heat at high T concentrations, similarly, so that the solar works 24 hours a day.
This possibility of geothermal solar is despised and never considered !!

One more proof that we manage in an absurd way, to stay polite !!


Methanization recovers everything that is wasted and lost in waste everywhere, but with a low overall solar yield.

Finally try to make seriously consider, the serious real risk of solar mega-eruption, before it happens, with an armada of nuclear power plants bogged down all over France, and as in Japan for the tsunami and Fukushima, we did not know, we could not predict, what scientists had said before !!

in the event of a serious disaster there will be no more gas either

in case of too serious disaster we will all be screwed ...

but in the event of an average disaster like the storm of December 99 there was 15 days of power outage and telephone!

there was no gas cut, but with the same power cut today there will be a gas cut, because most of the compressor stations on the GDF pipelines have been modernized 100% electric. the old compressor driven directly by a gas engine has been scrapped!

the people I knew who always had gas did not have any more heating anyway because boiler does not work without electricity

the generators sold everything on the first day ... but it was difficult to find gasoline: the service stations did not have electricity to run the pumps

fortunately the big box stores had their generator for EJP and were the only ones to sell gasoline

with smart prices like this it will give profitability to something really productive ... unlike the intellectual masturbation bonus bonus on the current energy that will confuse small consumers who can do nothing

Informative, we are less and less able to live as at the age of the caves, this over 12 years !!!

The mega-eruption or earthquake with a millennial tsunami (as in 1859 or 1755) will be much worse than the centenary storm !!

This system interests me as part of a project related to my work.

Unfortunately, I have not found any financial data: how much does all this installation cost: drilling, pipes, connectors, pre-tsocking and the control system? For what surface (or what heating power? [Well, the power, I can guess via the assessments that are put].

I put assessments of orders of magnitude and links on this type of interseasonal heating (on google) on econology to fix the guiding principles, which have been discussed on econology, with fairly disparate techo choices, shallow or deep, by Obamot often, and especially the serious problem of the circulation of deep waters, to be blocked if they exist by injections of product blocking this circulation, cheap cement ou same product making water solid by soaking up water.

A basic figure that fixes the ideas is that one stores roughly 10KWh / m3 earth (clay for example, a little more in the rock) by heating it from 36 ° C in addition to 20 ° C to 56 ° C (a Canadian well having 3 times minus 12 ° C, in variation of T gives 3 times less in reserve before freezing, with a heat pump)
You have to descend more than 3 to 6 m.

There are other various achievements and studies with published technical articles to read, which I did not research thoroughly.
For dlsc.ca, there must be detailed articles in paid trade journals to have the article.

The price in my opinion is very strongly a function of the methods of realization, the nature of the ground, soft or hard, the method of drilling holes which can be of small diameter with pipes of small diameter, as made by the specialists of injection of expanding foam to straighten houses and buildings with collapsed foundations ( Uretek or Géosec ).
I saw them do it, they pierce the foundations and the ground underneath manually with a long drill like butter with a perforating drill, quickly to thread pipes of small diameters, about 20mm, easily already a good depth of several meters.
I think that with the same system there is a way to greatly reduce the price compared to large wells of 150mm or 200mm well conventional for wells, a price however not astronomical.
It is better to increase the density of these small diameter boreholes;

At home, I want to try, to measure, with the simplest material, hand drill, long drill, since it is very simple with a simple inexpensive 16mm hose (the one for drip irrigation is very well, solid more than 10 years in the sun in my garden, usable in earthen holes, as well as for simple and cheap thermal solar collectors of summer shown on Apper, econology and internet, just under plastics.

It's super easy to make, except for me, get me long drills, put end to end of small diameter 20mm or 30mm.
You can easily find up to 1m but no more.
There are also sellers of drilling equipment who can generally supply larger diameters, 150 or 200mm or less as 50mm with a geotechnical borehole.
For a large project, the price of such an auger is not excessive, (price of car or van) used and owned by all soil survey professionals.
We should be able to rent them.
So the price is that of labor to drill, and then much lower than that of larger diameter drilling.

I want to try at home by drilling in my gardens with a perforator, far from the foundations of houses, (heating the ground is like having a heat wave that cracks the clay under the foundations and therefore the house). The best place is under the asphalt of a nearby car park, by drilling at an angle.

The only problem for me is to have long bits put end to end of small diameter. So trying and measuring the thermal properties of the soil is easy.
The problem is that professional equipment is not very accessible to DIY enthusiasts.

Otherwise the development of inexpensive and fast simple drilling would be interesting, with drill at the end of the small diameter pipe to bury and thread, with circulation of water and pressurized air to rotate the drill, and to remove debris, which would allow the pipe to follow a path in large U underground, as a kind of micro-robot (or like a robotic mole).
In my opinion, with a little imagination there is a way to greatly reduce the cost price, to very little.
Everything else can be very inexpensive, the pipe costs less than € 40 per 100m, put underground as well as under the sun !!

For the circulating groundwater, there is also a way to block it by injection of the product which swells and solidifies the water, or with pressurized cement, a method already developed for large-scale works.

I think, to identify the best solutions, that we must try simple, by investing not too much, just what is necessary, by avoiding spending too much, in what is not essential, and thus by trying different variants, of this system which is basically very simple compared to any other technological system currently used, such as a heat pump, a Stirling or a nuclear power plant.

It is accessible to DIY enthusiasts to develop with imagination.

In France we prefer big projects and we despise what is to be made cheap, specialty of the Japanese who made the general public inexpensive in large numbers, very expensive systems at the start, such as the microwave oven or the heat pump .

There is already a subject on this but this poor Dédé cannot do without rotting the subjects as usual !!!


He is good at everything and knows everything even if we always expect proof of his "achievements" which despite his 86xx "reply" do not appear but if we do a search on dlsc.ca we find Dédé more often than the site itself !!!
: Evil:


>> You say off topic ???


He is the king !!!
