    Well just like Formula E it's going to be a dumpster fire of entertainment anyway, This just happened without the dumpster.

    Foam works better but water will still get the job done. On both EVs there's an easily accessible cut off that kills the high voltage power from the car and keeps any high voltage things from being energized. If the HV battery cells are compromised and you have a run away the only way out is the batteries to discharge, that will either be a conventional electrical discharge or it'll runaway and catch fire.

    Commifornia is requiring solar panel installation on all new homes come 1/1/2020. It's not the same as retrofitting the systems and because it's designed into the home it will have lower costs, you'll also have lower panel cost as a factor of economies of scale. I can see both sides of the coin, it takes away the option from the homeowner but it's also pretty much guaranteed to pay itself off in almost every situation and reduces stress on the grid that people seem to complain about in that state. There are also ways around installing them on the individual home, things like community shared energy options. It removes the individual mandate and lets the developer determine how to implement the requirements.

    They probably have insurance on them for things like fire, flood, theft, damage and whatever else can happen off the race track.

    Serious question. What if the entire car is completely engulfed in flames? How do you get to the cutoff?

    If you're at that point whoever is in the car is fucked at that point. The purpose of the cut off isn't to prevent a fire it's to protect the occupants and first responders from getting shocked by the high voltage DC battery 350 or 400v depending on model. If you cut the safety loop it contains the power in the battery and de-energizes things like the motor(s), charger(s), charger port, heater, DC-DC inverter, etc. All of these items run directly on 350/400v while everything else in the car operates off of normal 12v like a typical car. All the cut off does is remove high voltage power from those things so firefighters have less concern about getting shocked by anything trying to get someone out, it has nothing to do with stopping or preventing a fire from the main battery.

    Cool. Thanks for the explanation. Makes sense. I wasn't aware you could be shocked by one. :eek:

    Obviously I know nothing about hybrid/electric cars. :D

    Perhaps not if they went with eInsurance. :crackup:

    Could be the tech but it could be as simple as the power they ran to the tent was done wrong or badly. On that note I was wondering where they get the juice, from the track or do they need a huge genset to charge everything?

    Batteries versus a power plant. The juice isn't the issue it's the battery packs.

    Fake news:

    From this study:

    "Based on investigations to date, all of the claims stating that the fire brigade could not extinguish a house fire due to the PV system have been found to be false.”

    Let's be honest. The pit fire was far more exciting than the racing would be.

    The actual situation seems more nuanced than what you said, of course the presence of PV panels on a rooftop changes the firefighting equation and adds some hazards that are not present otherwise. Given the proliferation of rooftop PV panels in Germany particularly, it's simply not true that firefighters there as a general policy simply refuse to combat fires in these structures and just "let them burn". That's ridiculous.

    I would bet that all the chargers would fit into a decent sized three phase disconnect. 200 amps theee phase maybe? Less than what you need to out on even a small concert.
