  • I’m no electrical wiz, but it seems like we’re dealing with a misunderstanding?
    When I hear “3 phase support”, I jump to it can be powered by at least part of a 3 phase supply without transformers. Which is what they clearly state in multiple sources:

    SAE J3400, with the support of a supermajority of OEMs, has made sound engineering decisions that will pay dividends for decades by lowering barriers to electrification in North America. … It supports AC voltages commonly available in commercial areas, streets, parking garages, and dense housing locations, specifically 480/277-V three-phase power, one of the most common configurations provided by utilities in the United States.

    I am not sure I understanding you correctly, you wanted them to feed all 3 phases to charging EVs? Batteries are DC, wouldn’t that mean sticking a heavy 3-phase to DC converter in the car?






  • Everyone else is saying vinegar, which will certainly work.
    But if you’re like me and cannot stand the stench of vinegar, then I recommend citric acid. 2 tablespoons to a liter of water is a good place to start, but you can most likely find dosage specific to your machine with some googling.
    Also, you can get ~2kg of citric acid for 15~25 $or€. I use it to descale everything from coffee contraptions, to shower heads; and a big bag of it lasts us 1½ years. Our water is fairly hard too, about 160 TDS.


  • It is a combination of how tall the front is, and if it sweeps backwards a bit, or is practically perpendicular to the ground.

    What matters is how likely a pedestrian is to be pulled under the vehicle, instead of pushed up onto the hood. You can have a fairly tall grill, if it is angled backwards somewhat. And it won’t be a near instant death bulldozer for pedestrians.
    Tall and flat is the most dangerous combination, and that is exactly the trend of most big and giant trucks & SUVs.
