Whenever wires don't make sense, as is the case for aircraft, synthetic liquid fuels can make sense. In a world where the inputs are free, the inefficiency of the process is not relevant.

Power-to-Liquids (PtL) have air as inputs, but that doesn't make them free. There's a high capex requirement to create the processing plants, and then the energy required to run them isn't free either.

i think his point was that if you are in a remote location with solar and or wind power, the power is free because you can't do anything else with it (without transmission lines)

		So apparently what you can do with that, is mine Bitcoin. This is a thing that happened. Which is fucked but that's a whole other discussion.
