>You were careful to say "on land," but I wanted to highlight it for anyone who isn't familiar enough with the argument to spot the hedging.
I didn't know saying what I meant is such a heinous crime. :) But to make things fun here's a nice strong claim:
E-Gas won't work for airplanes either.
That's because A) E-Gas converters are not free and not 100% efficient, so it's more like 5x the cost in best-case-scenario (vs 10x today), and B) the aviation industry is well aware that corruption is simply cheaper.
E-Gas will not happen. What will actually happen is more of the same:
1) aviation will continue to use E-Gas (and some costly demo flights) as a greenwashing tactic while behind-the-scenes working to soften climate goals,
2) eventually the intermediate technical-economic-policy compromise will be to only use fossil fuels for aviation, and
3) in the long-long term aviation will go electric too, only with slightly different routing and network design to accommodate the reduced range (this has a cost, but by then fossil fuels will be costlier).
E-Gas is good for nothing except greenwashing fossil fuel assets, hence the big push on HN. Gotta fool your talent pool that they're not 'really' part of the problem. This both lowers labor cost and delays effective regulation, since engineers tend to be thought-leaders in crafting future policy.
