    Bats are awesome!
    Recently read a post by some biologist, who was wondering how bats avoid crashing into each other, when they all leave or return to their narrow caves at the same time. He speculated that they must use their echolocation to evade other bats.
    But his sound recordings didn’t match his theory. So he set up a high speed camera at a bat cave entrance to film them.

    Spoiler

    They crash into each other all the time.



  • One more time, for those in the back:
    New types of nuclear power can’t be developed and built fast enough to help prevent the climate catastrophy. We need to (and are on track to) be carbon neutral in 20 years.
    Building new nuclear power plants is more expensive than any other form of energy.
    They hamper building renewables because they can’t be switched off quickly, which means they don’t fit into the flexible energy infrastructure that is needed to use renewables.
    They are unnecessary. Germany already replaced the power from nuclear with renewables, and are continuing to reduce coal power.
    Solar and energy storage capacity are exploding (pun not intended), and the costs are dropping through the floor right now.

    Even if nuclear power is 100% safe, it’s obsolete already.
