Of course, I have analyzed the chemistry and energy physics here:
The problem is liquid transportation fuel. Even if we had penny a kWh
electric power, building the plants to make liquid fuel takes
time--decades of time. And we don't have the low cost power.

Even bypassing the current hurdles, big engineering construction
projects take time. It's not entirely clear that we will be able to
make power plants by the time they are seen as the appropriate
