  • I think we still need more time/data to get the whole picture. EVs are still in their early stages.

    It would be interesting to look at fire rates for vehicles at rest. These types of fires have the potential to become quite serious, as they are often not immediately noticed, especially if the vehicle is parked in a garage or remote area. This additional time allows the fire to spread and intensify.

    Since EV fires are typically more intense than ICE vehicles, we should expect EV fires to cause more damage to the surroundings and to spread faster. Though, this danger could be offset if EVs have a lower probability of self ignition.

    We should also look at fires while refueling/charging. Lithium cells are most dangerous when charging and discharging. While an overfilled gas tank is easy to spot and may catch fire, a continually overcharged battery is invisible and will catch fire. Also, because of the long charge time of batteries, many EV owners leave the vehicle unattended while charging and would not immediately notice a fire if one were to occur. In addition, EVs are often charged at home, in close proximity to residences and other vehicles, and often within garages. These residential locations do not have the same fire safety requirements and suppression systems as gas stations, so a vehicle fire at home is already much more dangerous and has the potential to severely damage your home.

    We have had a century to figure out ICE, but it's still very early days for EVs, so only time will tell.

  • LiPo batteries of the same capacity actually have the potential to be much more dangerous than the sodium cell shown here.

    LiPo packs typically use flat, soft walled cells which are far more susceptible to being punctured. In the event of a puncture or overcharge event, high temperature enduring flames are produced, with the severity and duration largely depending on the amount of energy within the cell. LiPo batteries also degrade at a much faster rate (both over time and with charge cycles) and have been known to spontaneously combust in storage while at rest.

    With the sodium battery, the thrust produced by the puncture could have been easily been overcome by properly securing the cell.

  • Yep, less/no fire is very important when creating battery banks with many cells. The probability of single cell failure spreading to adjacent cells is reduced, making a catastrophic failure of the entire bank less likely.

  • The United States leads globally in school shootings, with 288 incidents from 2009 to 2018

    Over the same time period, Mexico suffered the second highest number of school shooting incidents with a total of 6.

    https://worldpopulationreview.com/country-rankings/school-shootings-by-country

    So, the USA had 48x more incidents than Mexico, the country with the second highest.

    Hum, gee, I wonder what modern data looks like...

    America number one bay-bee!

  • Does anyone even use FB anymore besides boomers?

    Ok, so boomers are not actually people, facebook's 3 billion active users don't exist, and 250 million of those fake people are certainly not from the fake US.

    But TikTok...

    Amazing how we are talking of Chinese surveillance while the US just renewed another one of its surveillance bills.

    So much "I am immune to, and can spot all propaganda" in this thread.

  • No, it's:

    "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

  • Come on. Those who actually believe in "neutrality" are either fools or liars. Of course China would have an opinion on the conflict.

    Anyways, the article is garbage and provides no evidence of any wrongdoing. It literally states that there is no evidence of China sending weapons to Russia, but then starts fearmongering and implying that whatever common goods are being sent are actually being used for war. Iraq's aluminum tubes pt 2.

  • Nah, mate. Killing random civilians isn't the same as killing slave masters. Random people on the street aren't the ones to blame. Needless blood is counterproductive and just fuels hatred. Being designated as a terrorist org means the slim possibility of receiving foreign assistance is reduced to zero.
