petrecki has a vision he wants to build a gravity assisted battery to compensate for the fluctuating nature of solar and wind energy if it works it'll be able to store millions of times more energy than a conventional household battery. vision is a system for storing large amounts of energy so we can increase the sheriff energy is in the grid. or right now it's about 30 to 35 percent that's the limit because the sun doesn't shine constantly what we need is a more economical and efficient storage system. and this is what his batteries will look like towers 60 to 120 meters high made of hundreds of cement blocks built around the 6 armed crane when there's excess energy in the grid it will power electric motors which move the crane arms to lift and stack the $35.00 ton blocks. now the battery is charged. when electricity is needed the blocks are let down again generators in the crane arms turn the potential energy of the stat blocks into electrical energy which is returned to the grid this leaves the tower discharged. to try to cement blocks essentially function the way the water in a p
