Are You Interested in Long Term Storage?

The storage in your model is that all lithium ion batteries or did you find any sort of market viable longer term storage out there? Yeah, it's interesting. I know California, the state has run some programs trying to sort of juice the development of some of those longer forms like flow batteries and such. We haven't seen a lot of offers yet for flow batteries. Also compressed air energy storage or so pumped hydro. There's also some gravity storage projects. So all of these look really interesting to us. And we would love to be able to pilot new technologies because part of what they're about is innovation.
