I've actually been thinking about the issue of energy storage a lot recently -- I've read a ton about how lithium-ion battery production is exploding (usually not literally), but it seems unreasonable to store enormous amounts of renewable energy in a device that itself has to be replaced after a certain number of cycles. The device used for pumped energy storage -- a tank (to simplify greatly) -- basically never needs to be replaced.
It's really cool to see a feasible alternative to batteries. I think climate change is the single most important problem anyone can be working on right now -- amazing that you've found such a massive lever to pull on this issue.
