  • I saw a Project Farm video where they tested various AA batteries, alkaline and lithium.

    One of the tests was how long each battery could run a fan with a constant energy draw and Varta Longlife got the worst score by far.

    Those had a made in Indonesia label though, I don’t know if they have different plants in Germany with better specs under the same name.


















  • The Saturn V could lift 141t to LEO…once. Also it’ll be at least another 5 years before we reach a stable max power version of Starship.

    For example the Falcon 9 v1.0 first flew in 2010 and the current Block 5 version first flew in 2018 with more than double the LEO capacity when fully expendable.

    If they configure Starship as fully expendable it can lift 250t to LEO (per SpaceX, so grain of salt there to be fair).

    As for the shuttle, I love it to bits and I’m sad it had to be grounded. It was refurbishable but not really reusable and the massive liquid fuel tank was discarded in each flight.
