The incredible scale of our existing fossil fuel infrastructure is pretty mind-boggling, though. Apparently there are 145,000 gas stations in the United States.

The incredible scale of our existing fossil fuel infrastructure is pretty mind-boggling, though. Apparently there are 145,000 gas stations in the United States. If someone today proposed building out an energy infrastructure that required the construction of one hundred thousand sites that each hold thousands of gallons of combustible fuel, fed by a network of trucks and pipelines from a vast array of refineries, fed by tanker trucks, extraction and drilling sites all over the planet...they would be considered nuts. The energy density for electric planes just isn't there. So we need to do something. Generating jet fuel from some carbon-neutral source is about the only sustainable path we have to keeping an airline industry going. A few thousand of these sites would be almost nothing compared to what exists.
