forums energies: society, ecology and clean technologies

With their "VPA-2", Areos-Energie AG sets new standards in terms of efficiency, cleanliness and profitability in the world of solar energy.
The unique system completely reinvents solar energy and impresses with its compactness and unprecedented multifunctionality.
It is therefore not only the missing element in the energy transition but a sustainable investment with ethically clean returns for institutional and private investors.

The "VPA-2" stands out on all these points from the already known solutions. Instead of just collecting solar energy, this system focuses on a single topic. There, unlike photovoltaics, it is stored as thermal energy and is not converted directly into electric current.
Thanks to the patented storage system, energy can then be stored almost without loss for many months. The system can deliver large amounts of energy 24 hours a day, 24 days a year. The thermal energy produced can be used as electrical energy or for district heating (eg hot water) or cooling (eg cold rooms), for seawater desalination or for several other purposes.





Thanks to the pooled solar energy, the heat storage heats up to 950 ° C.
There is a basalt stone infill inside the storage rack, which allows a storage capacity of up to 400 kWh / m³.
Due to the enormous surface structure of the heat storage mass (96 m² / m³), ​​the collected heat can be quickly absorbed, but also instantly delivered if necessary.
The patented structure of the heat accumulator allows thermal energy to be stored almost without loss for many months.
Even after six months of unused and stored reserves, almost 90% of the accumulated energy is still available!

How can you dare to say that after an article that has just shown the contrary?

Preliminary analyzes carried out following the 2018 eruption show that the average thickness of the lava flows in the LERZ is around 10 to 15 meters. Based on the calculation of the cooling rate, it can be deduced that it could take between 8 months and a year and a half for castings with such a thickness to solidify. Cooling and solidification of castings 20 to 30 meters thick could take between two and a half and six years.

Yes, but until then stored in molten sodium (which explodes and / or ignites on contact with air and / or water ...)
It is therefore a major technological breakthrough, ...

Tuesday, October 4, 2011 is officially inaugurated the Gemasolar plant in Fuentes de Andalucia near Seville in Andalusia (Spain). Based on concentrated solar thermal technology, the plant is the first of commercial size to use molten salts (a mixture of molten potassium nitrate and sodium nitrate) to store energy and thus smooth electricity production over 24 hours.

Kiki defecated:
Since the time that we seek to store heat, no one would have thought of rocks, volcanic or not?
