Earth is far from running out of resources. Earth had limited charcoal resources until coal was found and then the other fossil fuels. While fossil fuel is limited at an accelerating rate of consumption (maybe 100 years or more), it doesn&#

Any idea why they can't use hydrogen and oxygen directly? Or are they just using a smaller quantity of helium as a 'working refrigerant'?

I suspect it was done in the usual manner with wiggling requirements and re-writes several times over. Plus the people you may be replacing with software may be the only ones knowing the ins and outs of the system, thus dragging their feet
