My only objection is that LENR-CANR is choicest snake oil
so far. I.e., there's no EROEI to make as there's no ER.

Synfuels. See infrastructure. The challenge is to move on
from high pressures and temperatures to mild conditions,
where you need less energy input and the catalyst doesn't
Ideally, you'd run something at standard conditions. Just
what the plants and animals do.

Trucks are our main source of transportation of goods in most of the world. Not just within urban centres but between them as well. And buses would be the only hope for personal transportation if we can't, or choose not to, replace the personal vehicle fleet in a realistic timeframe.

You can derive everything from C1 feedstock. So basically,
if you have CO2, H2O and energy, you're golden.
> ????? What the hell am I missing when I react that someone's up their ass whenever they start talking about replacing oil with something that's only good for static electrical generation? How much oil is really used for static electrical generation anyway? Isn't most of it used for untethered transportation of one sort or another plus chemical feedstocks? Isn't coal the main hydrocarbon used for electrical generation? Isn't natural gas the primary liquid hydrocarbon used for electrical generation? ?????
