  • Windows kept doing things I didn't want it to.

    The last straw was when I had a 24 hours render running, and Windows decided to update and reboot 1 hour before it was done. I was using the computer at the time, RAM, CPU, and GPU were all at max, the mouse was being moved, I clicked "later" every time the update pop-up appeared, and it still rebooted.

    Linux does what I tell it to, and doesn't do what I tell it not to do. I didn't think that was a big ask until Windows.

  • The current cost to drive a car with green hydrogen from electrolysis (not blue or grey hydrogen from methane reforming) is roughly equivalent to $50/L (AUD) for petrol, or $120/Gal (USD) for gas. This is one of the reasons most hydrogen today is made from fossil fuels.

  • A hydrogen engine is so much worse for efficiency than a hydrogen fuel cell, and even that is not good compared to batteries. I'd estimate the round trip efficiency of a hydrogen engine to be about 10-15%. So for the same energy that could be used to drive a battery EV 100km, this car from Toyota could drive 12km.

    Additionally, hydrogen is not very energy dense per volume. A compressed hydrogen tank that replaces the boot/trunk of the car would have enough hydrogen for about 100km of range.

    Please let me know if I'm wrong about any of these numbers. For Toyota's sake, I really hope I'm wrong.
