Hokei, so. Usb “packets” are 12 bytes or something, and it’s not good for performance to stop the flow. The solution is, as always, to have a buffer. Problem is that some kernel geniuses decided that GIGABYTES is a good buffer size. This was all when spinning hdds were the standard and new fast usbs were comming, but still.
Oh, and for some reason the transfer bar sometimes works fine for me.
Turning heat into mechanical or chemical or electric energy directly is really hard, you know.
It’s funny that you can get more energy from gas by using it to heat water and using a steam turbine to drive whatever. It’s just not always practical.
