  • I think it is more specifically electric planes as large as commercial airline passenger planes are impossible. It has a lot to do with battery mass to energy content ratio. Kerosine is about 46.4 MJ (megajoules) per kilogram. Lithium-air batteries, for example, only have about 6.12 MJ/kg.

    So, that means you need 7 times as much battery (in mass) to have the same energy content of kerosine fuel. Naively, we can maybe say that means electric planes only have 1/6 of the range of an equivalent kerosine plane.[^]

    Interestingly, lithium-air batteries theoretically have the largest possible energy density for any battery at 40.1 MJ/kg.

    ^ The calculations are really basic and probably only slightly reflect reality (since there are many other important factors. For example, Hydrogen has a lot more energy per kilogram than kerosine, but because it is much less dense, it has much less energy per m^3 than kerosine. This has made hydrogen gas very impractical for either internal-combustion engines, or planes), but I think it gives an idea of what the problem is.


  • It works very well for me. My evidence that it is private is that I download plenty (more than 1 TB per month) and I never get a copyright notice from my ISP. When I torrent non-privately I get plenty of copyright notices, sometimes several times for the same torrent.

    It does have, however, some major performance issues. It can be very slow, and it can use up a lot of RAM and a lot of CPU. Its internal database, which saves state of downloads, frequently gets corrupted at which point it has to be re-generated, meaning the list of torrents (not the downloads) is lost. It can be quite a bit slower than other torrent downloaders, and sometimes torrents stall for a while as it waits to prepare the network, especially at start-up.

    It’s been getting a lot better though with every update, which is quite frequent.
