I liked his post "Why Energy Storage is About to Get Big, and Cheap". In this article he says that Tesla Storage is not quite cheap enough for most to buy on a purely cost-benefit basis, yet. But it will be in 3 to 5 years, if not sooner. I find that really exiting. I'm wondering if they will be able to keep the supply up with the demand once this really becomes a smart cost effective move for a lot of people. Even with the huge battery factory Tesla is building.
Yes, it's really exciting. I'm convinced that this kind of storage will open big new markets.
