The solution proposed by the Ticino start-up is an electricity storage battery consisting of blocks of concrete that weigh 35 tonnes each and a six-arm crane with a novel design. These “bricks” are stacked one on top of the other in the shape of a tower, like pieces of Lego, to store up power when there is surplus. .

Hundreds of billions of francs are likely to be invested in production of large-scale batteries in the next few years. Research has been pursuing a. .
The electric battery project was originally the initiative of an American, Bill Gross, whose company Idealab in California has already promoted 150 start-ups active in new technologies and the renewable energies sector. To.
