  • I’ve found a couple plugs “upgraded” to 3-prong by jumping the load and ground together. That made for a fun firework show when my metal fan touched something metal. Even the landlord was impressed by that stupidity.

    Ah, the good old reverse polarity bootleg ground.

    Fun fact: RPBG is the one fault that those plug-in outlet testers can’t recognize

    Edit: Wait, no, that would be hot bootleg ground, they should catch that. RPBG has the hot and neutral switched, and also a bootleg ground to the neutral that’s actually hot







  • The comment you’re replying to is deleted, but from your comment I assume it was about hydrogen as fuel?

    Hydrogen fueled vehicles are generally electric, using a hydrogen fuel cell, rather than being internal combustion using a hydrogen engine. Compared to battery electric, hydrogen has the benefit of fast refueling and higher energy density, but has the drawback of difficult storage and lack of refuelling infrastructure.

    As a vehicle fuel, I think hydrogen does have a future, but only in commercial/industrial, particularly shipping. Semis already have predictable routes and stops/depots, and building hydrogen refuelling stations into those depots wouldn’t be too complicated.

    Hydrogen passenger vehicles, with gas stations being replaced with hydrogen stations, will never happen.








  • 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.
