Imagine having no good public transport

Only send updates of position of the players that are likely to be visible ?

I could actually “feel” my body turning off but then I notice it and move which makes me fully awake again and I have to wait for myself to fall asleep again

You can use liquified hydrogen which need to be chilled and insulated, and will evaporate away in a short time if not properly sealed

Or you use compressed hydrogen which means you are basically carrying an IED that weighs several hundred kilograms with the amount of pressure inside the gas tank

And hydrogen combustion is as others have said, inefficient.

Another issue is that you also need to use basically pure oxygen if you want to use a hydrogen fuel cell, otherwise the catalyst inside the cell would get poisoned

And well, there is a car that did all that, the Toyota Mirai, but that also pretty much ended in commercial failure, due to lack of hydrogen filling infrastructure and a whole load of other reasons.

Which is why I use my mouse in onboard mode after setting it up with someone else’s computer

Ever heard of domestication?
