The REASON Why SAND BATTERY So IMPORTANT Is For The Coming Future!!

[@Strazi7]

My grandfather built a house in the early 80's on Cape Cod that used this technology and it still works today! He used finely ground pebbles instead of sand. The front side of the house was a slope. The first story was all greenhouse windows and the second story part of the slope was solar panels, but the solar panels were not electric. They consisted of simply empty space between the glass and black aluminum foil on the back side. When the sun was out, a fan would blow the heated air that was trapped in the empty space between the glass and the black aluminum foil to the underground rock bed where the heat was stored. 1 sunny day would store enough heat to heat the house for several days. To heat the house, a fan would simply blow air through the rock bed and up through heating vents positioned on the floors. The water in the house was also heated using the rock bed. He was an engineer for Grumman.

Amazing

The concept is awesome. Your idea could use a little tweaking and I know of another source that is available and the volume of excess heat generation is substancial, it is within electrical generating power plants, there is a 30% loss of energy potentiol due to heat generation, it only makes sence to use this sand battery system to convert heat loss right back into usable electricity.

15 years that I hear the same story... "IT WILL REVOLUTIONIZE BATTERIES", they already said...

Blah blah blah. For someone who thinks realistically, it’s clear that this innovation is just crap… I wouldn’t even consider to be an innovation
