California firefighters had to douse a flaming battery in a Tesla Semi with about 50,000 gallons (190,000 liters) of water to extinguish flames after a crash, the National Transportation Safety Board said Thursday.

In addition to the huge amount of water, firefighters used an aircraft to drop fire retardant on the “immediate area” of the electric truck as a precautionary measure, the agency said in a preliminary report.

Firefighters said previously that the battery reached temperatures of 1,000 degrees Fahrenheit (540 Celsius) while it was in flames.

The NTSB sent investigators to the Aug. 19 crash along Interstate 80 near Emigrant Gap, about 70 miles (113 kilometers) northeast of Sacramento. The agency said it would look into fire risks posed by the truck’s large lithium-ion battery.

    1. Solar panels need to run for a couple of years before they produce net energy considering the energy invested into production

    2. Source on battery production being less reliant on rare earths?

    3. Speak English, please - I am not looking up abbreviations to argue with you

    4. See my other reply here: https://lemmy.world/comment/12349903 Efficiency of an electrical car is better, but absolutely not “incredibly” better, as per the numbers I checked while writing that comment

    5. How much cleaner EVs are, depends on the source of energy mix (which at charging stations outside your home, you can hardly control) - if renewable energies are used, they are certainly cleaner. If fossil fuels are used, they are at best (not counting the waste from battery production and disposal) as much cleaner as the efficiency improvement (which is about 40% over Diesel engines, by what I calculated from sources that were acceptably credible for writing an internet comment as opposed to a scientific paper)

    6. I was not speaking about “mineral” resources, I was speaking about mineable rare earths. Because there are plenty in the Earth’s mantle, but we can’t get to those.

    7. Again, source please on how EVs do not need rare earths for batteries

    8. Agreed for the time being, but if research allows to improve the process for generation of hydrogen, it could be a cleaner combustion fuel

    In summary: I am not arguing for combustion cars, I am arguing against EVs not for individual use cases, but as a “this solves all problems with combustion engines” - because it is not a solution applicable to the world market for personal mobility.

    The best solution is a proper public transportation system - good bus connections and trains that can operate “by wire” without the need for batteries.
