Nobody thinks they'll get net energy out of this. They're spending energy to make carbon-neutral liquid fuels. The energy would have to come from renewables or nuclear for this to be useful.
- Gibbon1 8y agoThe energy return on energy invested is going to be abysmal. No more than 20% if that. That translates into synth gasoline at $30/gallon
- ip26 8y agoConsidering electric planes aren't feasible yet, how else do you plan to decarbonize airplanes?
- strainer 8y agoShort range electric planes are being manufactured presently. This wont be able to decarbonize anything until surplus carbon free energy is generated for it use - that need not take decades with proper governmental policies, but it means this technology will not lead the way.
- D_Alex 8y agoReplace, as far as practicable, with fast trains and maybe Hyperloops.
- aaronblohowiak 8y agoHow do you figure?
- Gibbon1 8y agoEstimate the cost of the energy inputs per gallon of gasoline. Account for the inefficiency and you get $15-20/gal.
