Finally, on the whole there would have been more sensible things to do with all this money, such as insulating public buildings, they could have saved money.
Well, this is not the debate.
MYRTLE Corsica store solar electricity into hydrogen

rather storage in molten salt for Corsica
200 to 1000 times more expensive per m3 than free land, false idea by false habit.
1 liter of salt to melt is worth one m3 of free earth with holes in it !!
In addition, carrying batteries recharged by this heat via a Stirling or turbine is easy.
Finally sherkanner is right, this money used to insulate thermal colander buildings would have been much more effective.

You have no idea how much I don't believe you. No you really have no idea ...
Go and offer that in Spain with their solar oven in Seville and you will see how they will respond to you .. they who need high temperatures to keep the power required to run the turbines and keep up all night.
The performance of what you recommend is no match.
In this case it is not the right application adapted to the situation. Sorry.

Yes, but when a proven reality is denied, you have to react well.
I ask Obamot and many others to read this informative report on this power plant in Seville, YesThey have not resolved this storage for more than 50 minutes at 50% of the maximum capacity of the steam generator, to avoid stopping shocks when an unhappy cloud passes over the mirrors !!
These are 4 huge containers of pressurized steam, real bombs, limited by their price and volume, and also heat losses at max 50 minutes !!

http://en.wikipedia.org/wiki/Solnova_So ... er_Station
This power station is supplemented at 15% by a gas generator on days without sun and nights.
So no solar power plant has real storage from day to night, because this is not possible in terms of volume, thermal insulation and price.
The molten salts cost around 1 € per liter, and the free earth (or lava of volcanoes) comes down to this price per m3 with drilling, without any container or high pressures.
It does not seem to have been understood that la free land allows this long-term high temperature storage on very large volumes, not only for heating at www.dlsc.ca , but at high temperature, as does the magma chamber of a volcano, which exists under the city of Naples and even Tokyo (Mount Fuji) and many other places, such as the supervolcanoes ..
It is appalling that this very simple, is not understood and used at all.
Yet it is the cheap solution to make solar renewable continuous instead of intermittent.

Free land? What type of aggregates (and not soil) will we find (?) And at what depth? What about the drill head when it reaches the magma ( )
Yes!
This especially since there, it is not so much the insulating power of the soil that is sought but its optimal capacity to retain heat at high temperature! (see solar thermal ovens)
Honestly, I can't see them digging underground to store the heat of the sun in the molten lavas. I'm barely exaggerating when I read the words above, but it's just to show how our national crocodede can sometimes be very funny!
Obviously, only HIM has THE solution

Obamot, blocked, refuses to understand, in bad faith systematically !!
The lava of cooled volcanoes withstand very well being strongly heated, but even the clays which end in bricks !!
Floor insulation is achieved by the slow thermal diffusion 3 to 6 m / (an ^ 0,5) or less of mm / (s ^ 0,5), like the square root of time, that Obamot systematically refuses to understand and as soon as the dimension of the almost spherical volume of soil used has a radius greatly greater than this diffusion length, we lose almost nothing in heat.
This is the case for the large amounts of heat to be stored for solar power plants.
It is frightening that this ultra simple and also inexpensive, is not at all understood or used.
Free soil retains heat as well as molten salts (a particular form of soil) to a factor of 5, but salts require expensive solid containers resistant to corrosion of these salts, and cost around 1 € per liter, against less than € 1 per m3 of earth with drilling, which it does not change, perpetual, unlike the salts and their pipes.
Finally if we reach the magma, the solar is useless, by the true geothermal energy of the magma, at more than 1000 ° C, but unfortunately no pipe can resist this temperature for a long time under pressure !!
