It's odd to think about the danger of such concentrated energy sources. Right now I'd treat a couple gallons of kerosene with way more respect than a battery. But if this battery tech was deployed, it could be more dangerous than liquid fuels in certain ways.
- frankus 4y agoIt largely depends on how easy it is to get the energy out all at once. A stick of butter represents about 1kWh of chemical energy, and a 2000kg vehicle at 225 km/hr represents about 1kWh of kinetic energy. The latter is intuitively more dangerous because the energy could easily be transferred (to e.g. a person standing in its path) in an instant. Heck the specific energy of any given piece of matter is c squared, but we don't (as of yet) know how to get it out except under a few very special circumstances :)
- ComputerGuru 4y agoNo need to give such examples out of left field. Just compare the danger of a gallon of gasoline vs a gallon of diesel. Or a stick of TNT vs a an eye dropper of plutonium.

New York City has a big and growing problem with people charging scooter-sized electric vehicles in apartments.[1] [1] https://www.nytimes.com/2023/02/21/nyregion/lithium-ion-battery-fires.html https://www.nytimes.com/2023/02/21/nyregion/lithium-ion-batt...
