Yup by far batteries are the bigger deal. If battery prices were minimal then it makes household solar far more feasible to begin with.

- foobarian 1y agoThe OP numbers are fascinating. I wonder how the equivalent to the "station wagon full of tapes hurtling down the highway" looks for batteries.

I think the best are only about 500Wh/kg, so a shipping container* full of them would be 28870kg * 500Wh/kg = 14.44 MWh, so if it takes an hour to the destination it's about the capacity of one not particularly thick cable. Cables are great for electricity. If the (aluminium) cable had a cross section of one square meter, you could get all the way around the planet and back to where you started with just 1Ω of DC electrical resistance. * https://www.maersk.com/support/faqs/cargo-weight-limit https://www.maersk.com/support/faqs/cargo-weight-limit
