Especially frustrating is that it's entirely within the realm of hobbyist technology to build the bloody things. Indeed, if you're okay with making soap and canning food, you probably have everything you need to safely make them. I think part of it has to do with little opportunity for repeat sales or lucrative maintenance contracts. They're typically marketed as "the last battery you'll ever need," which can also make people more willing to spend more on them. I think, if SRP hadn't grandfathered us existing PV customers with their new "fuck you" rate schedule, I'd probably be building a nickel-iron battery right now. Instead, I've got a monthly auto-deposit to a savings account going...when the confluence of battery prices, utility policies, grid stability, and how much I've saved up in that account come to the right balance, I'll buy something off the shelf. Might even be a Tesla several years from now.... b& -------------- next part -------------- A non-text attachment was scrubbed...
