The best absolute energy!

[dedeleco]

is just a way like any other to heat, it will not help us to propel a train ...
Besides, renewable energies are often sidelined for their inability to generate as much energy as petroleum or nuclear.

is archival because you do not read what I write!
On can store underground intermittent summer solar heat concentrated by parabolic or other cylindro collectors at 300 ° C, exactly as it has been stored underground in volcanoes for 4 billion years, and use this stored heat continuously day and night, from summer to winter, in smoke-free thermal power plants.

It suffices:
1) become aware of it !!
2) to reflect and to convert our minds to adapt existing technologies which are working towards this heat, what is already being done in geothermal energy in Iceland or elsewhere !!

Finally I am frightened by the difficulty of ecologists to imagine combinations with existing technologies !!

What falls from solar heat on our roofs, paved areas, roads and parking lots is enormous, and wasted completely, concentrable in summer and can be stored underground, for example in car parks and used in winter.

The sums sunk in nuclear, ITER, the military, would be largely sufficient for this conversion just start !!
Since we copy most like Panurge sheep.

The best energy is not that which we do not consume, because I am not an ardent supporter of degrowth.

My little comfort, I want it like the apple of my eye!

No, the best energy refers to technologies still to be built, those of surunity.

Long live surunity!

Well, initiate the conversion. Start at home and then help your neighbor do it at home. That's how it works, not while waiting for a gesture from the state.

PS: please stop banging on the green. If they weren't there, we wouldn't even be questioning ourselves, and most importantly, don't put everyone in the same basket. Thank you.

[chatelot16]

there are only 2 sources of energy on earth: solar and nuclear

coal and oil are only solar energy stored in the basement for thousands of years

deep geothermal energy is only the exploitation of the heat from the center of the earth of nuclear origin

looking for solar energy is also nuclear, since the sun is only a big bomb H

before exhausting the fossil fuels we will have to organize ourselves to be satisfied with the solar energy that falls on us every day, either by direct solar collector, or by crops or trees

firewood is the oldest use of the sun for energy! the total yield is not huge but the trees build themselves

[FPLM]

It makes sense but a bit radical as a shortcut ...
You forget gravity too.

[dedeleco]

Agree with Chatelot16, except that Coal and petroleum is rather solar energy stored for hundreds of millions of years, over nearly 600 million years with certainly methane and abiotic oil of origin 4,5 billion years of the solar system, like on the Titan satellite !!

So there are huge quantities of them underground enough to multiply CO10 by 2 as 56 million years ago and raise the seas by 70m over one or two millennia to 2 to 4m per centuries, inexorable rise, impossible to stop, once started, as there is 15000 to 10000 years it happened spontaneously !!!

So we will grill at 15 ° C more on earth by taking refuge at the poles, long before having completely exhausted the fossil fuels !!

Also, you have to make the conversion very quickly, by ceasing to want to amortize over 10 years, by seeing only our immediate nose.


Finally the energies in our universe are not only nuclear and solar (which is also nuclear) but also the expansion energy of the universe which has been released for 13,7 billion years, with even a measured acceleration, energy of the real vacuum, which allows us to exist, which started with the energy of the Higgs quantum field full of condensed Higgs bosons which imbibes us, enormous release of energy which was the beginning of our universe, which is intimately mixed with the structure of the gravitational space time of our universe and therefore the properties remain to be discovered, certainly unimaginable, as quantum mechanics was unimaginable in 1900, with properties that the goofy of free energy or emptiness are incapable of imagining, since reality is always surprising, much more subtle, than the capacities of our brains which derail without the proofs of experimental reality.

Calm down!
I was referring to the drake solar landing system only.
For geothermal storage you preach a convert, but it is not concentrated solar that offers the most solution, given the limited sunshine in our latitudes, unless you use Desertec.

[FPLM]

Or it is dedeleco absolute energy!
Watch out for burn out guy.

[dedeleco]

pretty wrong idea in summer, heat wasted totally now !!!
Especially all the south of France, and also in the north !!

First, we have to change our preconceptions with real numbers and stop thinking with depreciation over 10 years instead of profit over 1000 years, avoiding the inexorable rise of the seas of 70m !!

Do not forget that our ancestors between -15000 and -8000 years saw go up the seas inexorably, 120m and if we lived in this period, we could do nothing, with peaks at almost 4m per centuries, huge gigantic debacles digging 1000m deep valleys (in the USA), engulfing entire countries in one day (Atlantis, North Sea, Baltic), without being able to do anything, even with the CO2 then very low.

If we start this process with CO2 (only the threshold is subject to dispute in a factor of 4), it becomes irreversible inexorable for 2000 years of rising 70m from the sea !!

Southern Europe is the most promising: Spain, Portugal, Calabria, Sicily, Greece.

In metropolitan France, solar islands should be used (quite feasible).
However, the most efficient solution in terms of energy conversion with a low thermal gradient remains the vortex tower, with heat storage underground / greenhouse in summer and recovery in winter using heat transfer fluid collectors.
