That is incredible...
Hate to be on that boat...
Truth hurts...
i have a paralyzed friend who basically lives in a motorized wheel chair powered by a Lithium Ion battery and I warned her and she scoffed. 2 months ago she saw the news story about the paralyzed woman living in a wheel chair in Silver Spring, MS whose wheel chair suddenly burst into flames Now finally after reading the news accounts and learning that was not a stand alone incident my friend took my advice and swapped her Lithium Ion battery powered wheel chair for a heavier wet cell powered one. It is heavier, slower and doesn't last as long but at least she won't be sitting in her chair screaming as her bottom burns before the house goes up in smoke.
BTW, if you own a cell phone, never go to sleep while it is charging and be super careful if you drop it.
A few weeks ago I asked a fire fighter friend how they extinguish electric vehicle battery fires.
He said “Oh you mean like a Tesla or something? The answer is you can’t. You cordon off the area, and spray a fine mist of water on the fire to try to keep the temperature down until it finishes burning. Takes a few days until it is safe”.
The problem is, besides being highly flammable, lithium is literally the lightest metal. At atomic number 3, it is the first element in the periodic table which is a solid. The two previous elements, hydrogen and helium, are both gasses.
Lithium is so light, it floats on water (lithium density 0.543, half the density of water). Lithium is entirely happy to blaze away while sitting on the surface of a puddle of water.
So if you try to smother a lithium fire with sand, the sand sinks to the bottom, and the lithium floats on top.
Lithium melts at 180C / 356F, and burns at 2000C / 3632F –
almostmore than hot enough to melt steel, more than hot enough to destroy most composites and metals like aluminium.The fumes from a burning lithium fire are highly toxic, capable of causing death or long term dementia like brain injuries – so you need to keep members of the public at a safe distance. Fire fighters need to wear respirators if they approach the flame......
