So, as it turns out it's not necessarily the energy demand of #syntheticFuels/#eFuels that is mind bending.
Its #water demand is even more mind bending.
Falter et al come to the conclusion that: "The water footprint consists of 7.4 liters per liter of jet fuel of direct demand on-site and 42.4 liters per liter of jet fuel of indirect demand"
By the way: I don't see any reason why the numbers should significantly differ for car fuel.
Let's say the 42 litres will magically solve itself by #innovation and somehow #efficient processes (yeah, we hear you FDP, the future is going to be great!).
Then there is still a demand of 7 litres per litre of fuel on-site. On-site (as discussed in Germany at the moment) means: sunny regions towards the equator, deserts, South America, Africa, well basically were ever the colonies were.
This debate is stupid, utterly, utterly colonialist.
