Hydrocarbons how come we never thought of that

If only there were some process that scrubbed the atmosphere of CO2, combined it with hydrogen to make hydrocarbons, and released the oxygen as a gas.

Seems far-fetched, I know.

This is good idea, but what about nitrogen? CO2 is too dilute in the atmosphere. We could use ammonia rather than methane.

That sort of reduces to the problem of getting the hydrogen. And the higher energy density of nitrogen compounds is not always a benefit. See Texas City, 1947

Hydrogen from water, or bio material. But, yeah, burning ammonia probably will lead to need for some heavy duty catalytic converters, I bet, to avoid smog from NOx. VW will be like, 'you thought we were bad. Wtf?'.

A pity that we can no longer burn them.
