Apparently my current shtick is that I talk about knives at great length. Also motorcycles.

  • If one of these were made for the US market it would obviously be configured to work at the US mains voltage and frequency. (Europe is 50hz, US is 60).

    Your home’s power input is also 240 volts in the US, regardless of being split into two 120 volt rails at the breaker box. It would be trivial to hook up a 240 volt system if you really wanted to, albeit not through one of your regular 5-15/5-20 outlets. You’d have to do it via a dryer outlet or something.

    Watts are watts. If the unit is capable of feeding 800 watts into your home’s electrical system, the voltage is irrelevant provided it can supply sufficient amps. A normal US household circuit is 15 amps, so a hypothetical US version of this thing would have to supply ~6-2/3 amps at 120v rather than ~3-1/3 amps at 240v. No big deal. It’s not even close to maxing out a single residential circuit on either continent.



  • “Common law” has no relevance to state law matters in the US (nor Federal, for that matter). Here is the relevant statute in this case:

    The bar for trespass is met only if the perpetrator has been “forbidden” from accessing the property by the owner. This does not have to be in person, or verbal. A “keep out” or “no trespassing” sign would suffice, and this is why such things exist. In this case I would be immensely surprised if there weren’t some kind of employees only, authorized personnel only, or keep out sign posted on whatever method of ingress was used to reach the inside of the sign.

    The intent of this is clear, it’s so nobody can get done for merely setting foot on a property in some situation where they didn’t realize they’d left public right of way or a property where they had authorization to be. You have to tell the person to GTFO (either preemptively or upon discovery) and if they don’t, then they can be arrested.





  • Well, metallic sodium liberates hydrogen real fast on contact with water, which I guess is tantamount to the same thing.

    Yes. But not to the same level as just dropping a brick of pure sodium in a bathtub. In a battery like this there is not pure lithium/sodium/whatever just sloshing around inside. The sodium is tied up being chemically bonded with whatever the anode and cathode materials are. Only a minority of the available sodium is actually free in the form of ions carrying the charge from cathode to anode.

    Just as with lithium-ion chemistry batteries, it is vital that the cells remain sealed from the outside because the materials inside will indeed react with air, water, and the water in the air. Exposing the innards will cause a rapid exothermic reaction, i.e. it will get very hot and optionally go off bang.
