ENERGIESTRO invented a flywheel made of concrete, that will reduce the cost of energy storage by ten.
Solar energy has become the cheapest of all energies, but it requires storage to become available night and day. Batteries are too expensive because of their short life. Current flywheels have an infinite life, but expensive materials: steel and carbon. Energiestro is developing a new flywheel made of low cost concrete that can store solar energy at a fraction of the cost of batteries.
