Problem is packing more energy together and using more plastic than steel. We don't hear too much about Leaf battery fire, because there are lots of steel between cells. It's low range, but i can add external long range storage when needed.

The industry typically uses MW to specify generating station capacity. For instance, Burns & McDonnell specify the output of the Rocky Mountain Cabin Creek pumped storage hydroelectric plant as 300-MW: https://www.burnsmcd.com/projects/cabin-creek-hydro-electrical-controls-upgrade Danke, -- Don, KB7RPU, https://www.qsl.net/kb7rpu There was a young lady named Bright Whose speed was far faster than light; She set out one day In a relative way And returned on the previous night.

The state of the art is this: https://cfpa-e.eu/an-extinguishing-agent-specifically-developed-for-lithium-ion-battery-fires/ There's no reason it can't be scaled up for the 3MW jobs. Bunch of demo videos showing how fast it works. https://www.avdfire.com/videos/

Good for garages.

No need to save burning batteries. Just let them burn out. Perhaps using smaller containers and space them out apart. There are plenty of spaces around the power plant.

I guess local fire departments would have to haul around tanker trainers of this stuff. Battery packs could be designed with space between the cells to let this stuff in. Makes them bigger. Lithium battery fires in garages are at the very least bad press for electric cars. -- John Larkin Highland Technology, Inc The best designs are necessarily accidental.

My bad. I was thinking of Halifax in 1917 which was about three kilotons. A fire onboard the cargo ship SS Grandcamp docked at Texas City in 1947 detonated 2,300 tons of ammonium nitrate, which is in the same ball-park. A disaster in the Rhineland town of Opac in 1921 seems to have been just as bad. I have seen write-ups talking about a million tons of ammonium nitrate in warehouses going up but that must have been journalistic license.

When you are right, you are absolutely right. Stuffing such highly combustible reactants so close together is so dangerous. Gasoline and oxygen should be kept at least 6 feet apart in all vehicles. If they did that this would not happen. 1,400 cars in one fell swoop! https://www.thedrive.com/news/17287/massive-new-years-eve-parking-garage-fire-destroys-more-than-1400-cars-in-england Hundreds of cars destroyed, parts of the parking deck collapsed and even airline flights were delayed! https://www.thedrive.com/news/31763/norwegian-airport-parking-garage-fire-torches-hundreds-of-cars-grounds-flights It would be hard for any other energy means to rival the destructive power of gasoline. Isn't that the basis of the most massive conventional ordinances?

That is why I like driving my Tesla. It is just so responsive to the accelerator. Every car I've driven has issues with the engine response to the throttle even if they are small. The most common is the abrupt turn on of power at light throttle settings. The Tesla has a nice gentle touch but is ultimately controlling 500+ HP. Nice car. Never caught fire either. I've seen any number of gasoline cars burnt up along the road. I've never heard of car insurance being higher if you keep it in a garage, but your home insurance is higher if you have an attached garage. Yeah, a gasoline fire spreads VERY quickly. -- Rick C. + Get 1,000 miles of free Supercharging + Tesla referral code - https://ts.la/richard11209
