The main reason why this process isn't "something for nothing" is that it takes twice as much electrical energy to produce energy in the form of gasoline. As Aircela told The Autopian:

Aircela is targeting >50% end to end power efficiency. Since there is about 37kWh of energy in a gallon of gasoline we will require about 75kWh to make it. When we power our machines with standalone, off-grid, photovoltaic panels this will correspond to less than $1.50/gallon in energy cost.

Doesn't it sort of defeat the purpose of gasoline being used because it's so energy dense? Like, this seems to suggest little more than the benefits of electrification in transport.

Yeah, I was figuring similarly, but still. I've seen enough "harmless" "local" environmental changes spiral to know that at least some thought is warranted about it. I absolutely did not mean to suggest it would be harmful, just that I don't know enough about it and would hope that somebody knowledgeable looks into it before they recommend scaling.

Oh absolutely. I would never feel comfortable about any such projects unless several and different scientific institutions signed off on it being low to zero (or hopefully positive) impact.
