How to use gravity to store energy
Gravity batteries are a new big hope for storing excess renewable electricity. The idea is ingenious. Does it pass the reality check?
#PlanetA #GravityBattery #EnergyStorage
We're destroying our environment at an alarming rate. But it doesn't need to be this way. Our new channel Planet A explores the shift towards an eco-friendly world — and challenges our ideas about what dealing with climate change means. We look at the big and the small: What we can do and how the system needs to change. Every Friday we'll take a truly global look at how to get us out of this mess.
