    I like the idea of off-the-shelf tech, the contained nature of the facility (many siting options), and the plausible 60%(?) efficiency, but I sent it off to my sister (our dad calls her the “Pump Queen”) for skeptical review and assessment of its safety and maintenance. AFAICT, there are no community-toxic components.

    Footprint seems OK at 6,000 km**2 for 2,000,000 gWh


  3. The confusing graph ten minutes in illustrates an important drawback in expensive battery schemes (and they are all expensive) such as this. When you use such schemes to cover for hopelessly intermittent wind and solar, you run into increasingly infrequent but longer periods of no wind and sun. In order to cover for the longer periods, you need more of this expensive storage capacity, but since these periods are infrequent, all this expensive storage is hardly ever utilized.
