If they continue to grow foodstuffs to make liquid fuel, I might be the only person on Earth.
Much the same for making fuel in a lab. It takes a lot of energy to create 'liquid energy'. For example, there's massive electrical energy being wasted to create crypto currencies.
E-fuels make me wonder... They raise so many questions that I haven't resolved in my mind like:
1. Where does the fuel come from and what are the non-CO2 environmental costs?
2. Is this farm based fuel? If it is, how much land is required and what happens to the soil... farming is an intensive process and are you robbing valuable topsoil nutrients (for food) for fuel?
3. What's the difference between Gen I and Gen II biofuels? I am leary of the GenI Bio-Fuels (Ethanol) that we currently use... there has been evidence that it's a bad idea. How are GenII fuels better?
4. Do the fuels perform poorly versus standard fuels? (eg. Ethanol engine corrosion)
5. I think I saw it being called 'sustainable' fuels... does that mean they have some sort of equivalency formula for the cost of deforestation/land use? Or is this all CO2 based?
