Not disagreeing with you at all; just keep in mind that these conditions are ultimately no more dangerous than camping — where exposed, temporary electrical setups are common — which probably gave them a false sense of safety about the setup.
Real NASA systems would need to be orders of magnitude more safe/reliable, but I suspect this experiment was at least partially designed to identify potential failure points that engineering solutions need to be built for (I.e. what things can a human fix safely and what needs failsafes and self-healing).
- walrus01 8y agoThe Wh stored in their battery and the AC power of their inverter are significantly larger than that you'd see camping. Maybe what you'd see "camping" in a $90,000 50 foot luxury motorhome. I'm guessing the habitat has a battery bank of at least eight 12v 100Ah batteries (if AGM lead acid, or equivalent capacity), and at minimim one 4000W sine wave inverter feeding several 120v 15a circuits. Also sounds like somebody shocked themselves on the AC power side, maybe the generator transfer switch, maybe just exposed wiring. Either way there are safe ways to do temporary ac power with twist lock receptacle extension cables and distribution boxes that are insulted up to 600 or 1000V and won't shock people.
