Tesla Fires

The stuff they made the space shuttle tiles out of is pretty good, but I don't know about the cost.

This stuff is very cheap to make,with off the self material:corn starch,baking powder and PVA glue.The exact ratios are not know,or not revealed since the inventor died.

A carbon source,a substance that will expand when heated and something to hold i tall together.There are many copy-cats on the market,but I don't know if they are as good as the original.Some may even be better since they know the principle of operation

This guy discovered it by a serendipitous accident.He was trying to make a cheap hair gel.(He was a hairdresser). When he threw it away in his trash burn barrel,it did not burn,so he experimented with it to see what it would take to burn it....the rest is history,kinda like Vulcanized rubber was created when Mr Goodyear spilled sulphur on the rubber on his stove.

I am going to try in in a home made LP forge.

For what it's worth...

"The American company Thermashield, LLC, which owns the Starlite formula, stated in a radio interview that Starlite is not made from household ingredients and there is no PVA glue, baking soda or baking powder in it.^[3][16]"

..."In order to meet the growing need for battery shipment safety, PACT (a US-based packaging and crating company) developed a patented technology called Thermo Shield fire suppressant wrap. This one-of-a-kind solution consists of a lightweight pleated material with a non-toxic moisture vapor application that ensures the safety of lithium-ion products in transport by suppressing the fire and shielding the surrounding environment. It is the first of its kind capable of containing a lithium battery fire within specified corrugated containers for shipments on land, sea, and air."...

Then you could always use Teslas as hearses and save the need to build crematoriums, seems like they would be fit for purpose.

I agree with Lehman57 on post 7, and gave him a GA.

There are products in final design/final testing that will solve this problem.

These batteries don't create their own oxygen during combustion (like magnesium) so removing the heat will put them out.

Water can't put out such a fire as the boiling point is too low to remove the heat, which is required for combustion.

I'm not giving away any trade secrets here, but aren't these clues are enticing?

50 years ago, metal fires were quenched with graphite,used to extinguish cars with magnesium\aluminum engines and aircraft.It works by absorbing the heat of combustion. Some also had copper powder.That was a class D fire extinguisher.

Would these not work on lithium fire?

Some fire departments do not have these but should.

I have also wondered about using the Rockwood (Navy) nozzle with a long extension (to keep firefighters away from potential explosions) that is downcurved at the end to flood the battery with water.

The lithium battery fires are so hot they split the water into hydrogen and oxygen,and increase the flame intensity and increase the risk of explosion.

Water will cool down the area to prevent spreading but that's all it can do.

Then could we feed Starlite thru the applicator?

We called those "personnel protectors" in the Navy. We couldn't run from a fire or wait for it to burn itself out on a ship. They sure do put out a protective fog. I don't know why Municipal fire departments don't use them.

The problem with water (other that HTRN observation) is that the boiling point is too low to effectively cool the battery's heat of combustion. Water flashing to steam from the heat, removes that heat from the ongoing combustion process, which will cause the process to cease, once enough heat has been removed.

In this case, a much higher boiling point liquid is needed, such that more heat, per unit volume of liquid applied per time unit, is removed from the process.

Class D fire extinguishers should never be used on LI battery fires.

A better option is a dry chemical extinguisher, although there is no ideal method, yet.

Why don't they build the battery with a fire-suppressant wrapping that is permanently attached?
