  • I’m hoping that as EVs become more common, conversion kits become a thing. Both straight-electric and PHEV; I would love to pull the oversized engine from my truck (it’s a 4.0 in a Ranger, wtf, it doesn’t need that kind of power) and replace it with a diesel-electric motor-battery-generator combo. With a half decent battery, I would be running on electric 95% of the time; for the other 5% (which is camping on rough trails, no I’m not renting a truck for it), there’d be the diesel generator backup



  • If you’re making your diesel from CO2 pulled from the air, pollution aspects don’t really apply (at least, CO2 emission issues don’t, there’s still NOx, but that’s what cat piss is for).

    Problem is, converting atmospheric CO2 back into fuel makes the efficiency issue drastically worse. Maybe with enough solar panels and windmills, and use the Fischer–Tropsch process with the excess energy that the grid isn’t consuming.

    Of course, that would be for mobile fuel, if solar plants were going to do anything like that for later use generating electricity during peaks, making diesel is dumb; you’d want to use hydrogen or ammonia for in-place energy storage.

    A pound of dead battery doesn’t help me when I’m camping 10km from the nearest access to the power grid. (There are actually powerlines not even a kilometre from my favourite campsite, but those are going to be measured in kV, and so aren’t really useful to me.)

    Now, if I had enough solar panels in a mobile setup, probably folding out of a trailer, I could make it work, but solar panels are expensive.
