Some cheats are using PCIe FPGA boards to get access to game memory totally outside of the OS. The boards are controlled from a separate computer.

From linked reference:
Silver oxide-aluminium (AgO-Al)
Silver oxide-zinc (AgO-Zn)
Lithium-Ion (Li-Ion)
Lithium-polymer
Lithium-iron phosphate (LiFePO4)
1,040 Wh/kg
490 Wh/kg
600 Wh/kg
600 Wh/kg
520 Wh/kg
The F21 is powered by a new generation of silver oxide-aluminium (AgO-Al) sea-water primary battery using dissolved sodium dioxide powder as electrolyte and incorporating a new electronic closed loop electrolyte circulation system.
In comparison with silverzinc and other technologies, AgO-Al energy density is unrivalled. It ensures both maximum speed beyond 50 knots and endurance around 1 hour without compromising safety.
TIL: A silver-oxide battery (IEC code: S) is a primary cell with a very high energy-to-weight ratio. They are available in small sizes as button cells, where the amount of silver used is minimal and not a significant contributor to the product cost.

Probably some sort of safety reason .

Note: all of my messing around was just changing settings. No hardware/firmware hacking, so technically the machine is just as fine as before.
And I've bought the machine specifically for coronavirus, since my country health system is quite poor, I don't use it during the night.

We dont know if physical randomness truly is so. It could be pseudo random with a seed (superdeterminism)

Only if you're unconscious, and in that case you should be in a hospital anyway.
If you're conscious you'll just pull the mask off if you start feeling like you are not getting the right air. These machines, and masks, have all kinds of safety features and safety valves on them.
I have a CPAP, oxygen concentrator and assorted hoses and masks, and I've messed around with them these days while watching ventilator 101 videos on YT. If you're a technical person, the basics are not that hard to grasp.

Not sure if you are aware of "dissipative energy systems", a possible top down principle:
