Well done!  Amazing what nonsense can be dispelled with some scribbling on the back of an envelope.

Now the job is to get that news out there, so the propagandists get sneers and jeers when they try to push these lies onto the public.  The sooner we can eliminate the credibility of the non-options, the sooner we can get policy aligned with the things we have to do.

I suspect the enthusiam for biofuels has more to do with the fortunes which could be made than the potential for a solution. It may only end up being 1% of our fuel supply - but wouldn't you like to get your hands on the revenue from that one percent?
You could say the same about CTL - it may not sense from a global perspective, but a million barrels a day multiplied by $50 a barrel is nothing to sneeze at. Who will be the first CTL billionaire?

You could probably make a lot more money from building the energy systems to make biofuels into viable replacements instead of niche products with petroleum, but the visionaries behind these seem to be keeping quiet.  I probably would too, in their position; the less attention you attract, the further you can get before the people whose interests would be threatened start to attack you.
