Joulee the Free Salvage Tesla has an 85 kwh battery. Our solar plant has a 20 kwh battery. That means that we can easily send all the energy in the plant battery to the car, leaving the house in the dark.
Of course, we’re not likely to do so intentionally but Joulee occasionally decides to start charging on her own. So if I’ve plugged her in to charge, then stopped charging because our reserve is low, there’s a risk that she’ll start charging during the night and leave us with no power until the sun is shining the next day or we start the emergency backup generator.
I have a snapshot memory from my youth of a Star Trek (the original series) episode where Star Fleet is testing a new artificial intelligence called M-5. As so often happens in cheesy SF, M-5 decides to take over and make its own decisions, since it clearly is smarter than the puny humans. M-5’s creator defends it as it is still learning and bound to have some “minor difficulties.” Kirk feels it’s too dangerous, and orders Scotty to disconnect M-5’s power supply…
(Scott and an engineer get the device they use to attach M-5’s power supply to the ship, and head over to the junction box. But as soon as the engineer steps in between M-5 and its power, he is disintegrated.)
KIRK: That wasn’t a minor difficulty. That wasn’t a robot. That thing murdered one of my crewman and you tell me you can’t turn it off?
DAYSTROM: It wasn’t a deliberate act. M-5’s analysis told it it needed a new power source. The ensign simply got in the way.
KIRK: And how long will it be before all of us simply get in the way?
Since nobody can deliver like Shatner (you’ll have to manually stop the video after 30 seconds or so):
