As a former engineer, I found it interesting to read about a new fuel easy to produce,
How did you manage to pooch this so badly? Did you fail to understand because you're not very bright, or was it because you just read a headline from a conspiracy blog?
and costs only 85¢ a gallon,
No. The article didn't say it could make gasoline for 85 cents a gallon. It didn't say it could make ammonia for that price. It said that's how much ammonia _sells_ for. Do you understand the difference between a selling price and a production price?
A competent engineer would understand that there's no free lunch, energy-wise. If you're making a fuel that contains energy, that requires an energy input. A catalyst can make the process happen faster or at a lower temperature, but it doesn't change the required energy input.
So, your miracle process, if done on a large scale, would require grid energy to work, which comes mainly from fossil fuel, so you'd be burning fossil fuel to make new fuel. But since there are losses in the process, it would be a big net loss in terms of money and CO2 emissions. In some utopian future where fusion power gives us unlimited clean electricity, the process would be useful, but we are not in such a utopia.
Liberals understand such basic concepts, because such understanding is based on science, engineering and common sense, and people possessing such qualities are almost always liberal.
