How many AA batteries is that?
- lazide 2y agoI suspect tongue in cheek - but - this seems funny to analyze. I found an estimate for a typical AA batteries energy content as 4 watt-hours. (14.4 kj). Rounding the energy output from ‘the geysers’ to 6 Terawatt hours (6000 gigawatt hours), means 1.5 trillion AA batteries per year, every year. That’s a lot of battery changes! In fact, if someone went around doing nothing but changing batteries, 1 per second, 12 hours a day, 365 days a year, they’d need a staff of approximately 100,000 of those people to keep up. I can see why it was more economical to do what they’re doing. Also, apparently only 4 billion AA batteries are made per year [https://www.sciencedirect.com/science/article/pii/S2351978920307794/pdf https://www.sciencedirect.com/science/article/pii/S235197892...]
