Acid Explosions are bad emkay?

Yes

it's already been done. just ask the passengers of the Hindenberg.

That some kind of new meth lab or something?

It's not magic. Lead acid batteries generate hydrogen when they are charged.

I don’t think hydrogen creates a big orange flame does it?

 

[OLDRAAT]

I believe it does when it hits O2

 

[coolchange]

The bright white flame you see from top fuel cars is hydrogen.
I think the hydrogen from that battery is just a rich low temp burn.
Ever have a battery blow up in your face?

 

[Mandelon]

Is there a benefit to this experiment?

How long would it make a flame?

as long as you keep a charger to it and there's water in the cells

 

[OLDRAAT]

Watch a ULA Delta IV Heavy launch video and you will see the hydrogen flames reach upward around the craft.

Hydrogen generator!

 

[Taboma]

Hydrogen generator!

Yes, just imagine if you placed several batteries rigged similarly, then piped the hydrogen to your car's intake, you could run your car on self-generated hydrogen gas ---- and then claim the car runs on distilled water you simply continue to add to the batteries.
(For the sake of the added dramatic effect of perpetuating a conceptual hoax, let's all forget the battery requires a power source to generate the power to charge it ----- but wait claim critics ---- what if the engine that the hydrogen powers is also used to charge the battery ?
Great question, and that folks gives birth to the magic of perpetual motion, the laws of thermodynamics be damned. )

To bad those that rule the very fibers of our beings, would never allow it.

@OLDRAAT provided the answer. The flame is almost 100% hydrogen. It's explosive when mixed with oxygen in concentrations above 4 or 5%.

Some data centers I built used large wet single cell batteries to back up the UPS systems. Each battery holds several gallons of electrolyte. Each battery produces two volts, and in most installations they're strung together in series of 180 or 240, which makes the open circuit voltage 360 or 480 VDC. The float voltage is 2.25 volts per cell. Recharging is done at 2.35 VPC.

NFPA codes require exhaust ventilation in the battery rooms that keep the hydrogen content of the the room's total volume below 1%. That's not hard to accomplish. The room I have pictured below would have an exhaust fan moving less than 1,000 CFM.

All you need to make it work is a wind turbine generator mounted on the roof of the car. It would provide electricity to charge the batteries while driving, which would produce hydrogen to be burned in the engine.



Actually the amount of hydrogen produced by a lead acid battery being charged is quite small compared to battery mass. All of those batteries pictured above wouldn't produce more than 200-300 CFM of the gas when being charged at 2.35 volts per cell.

 

[pronstar]

[DaveC]

Take away from all this is lead acid batteries have explosive gas emitted when charging. Plan accordingly

I thought everyone learned this is shop class? I did

Gotta get those batteries boiling baby
In a past life I knew a young budding sparky wearing Army green who performed an experiment.
On a boring cold winter day while working in the boat repair shop, he placed an empty glass coke bottle upside over just one of the cells of an 8D battery after it had been charging for awhile.
Held it there for probably less than a minute. Returned to his desk, sat in the chair, turned the bottle upright and immediately lit it.
The explosion that followed was far more dramatic than expected --- by a LOT.
In addition to the deafening sound and two feet of orange flame that shot straight up, the sparky found himself still holding only the bottom half of the coke bottle, the top half, having cleanly separated from the bottom half, lay shattered on the shop floor about 40' away. The separation was so clean, it was as if somebody had wet sawed the bottle in half and not a single crack was visible.
How that sparky went home that day without missing his entire right hand is a miracle, but I can personally attest to the fact -- the dumb shit never, ever attempted to repeat that experiment.

Kids, do NOT try this at home

That was like a 747… waaay over my head

What was the purpose of initially shorting out the hot to the negative?

Reminds me of the oxy/act bombs I tried once. Smothered a good flame off the welder and filled an inertube with it. Poured some gas in the parking lot and light it on fire. Then threw the innertube in the flames. The sound that went off set off car alarms for blocks. We were all surprised we didn't blow out any windows in the buildings it was so loud. We ran away because we were sure someone had to call the cops on it.

To prove the battery had no charge. It would have sparked if it had a charge. He basically vented the battery so the hydrogen gas that emits when charging would vent out and he lighted it to show the flame.

exactly, haha. Can't be bothered with a volt meter. The other thing he doesn't tell you is that is full of acid. Get some on your clothes and wash them and see what happens.

The warrant officer that ran the shop was not one bit amused ---- if looks could kill
If I recall, he rewarded my success by having me mow the grass out front of the shop for a month.

This is a post I made last year about amateur oxy-acetylene bomb making. It details just one of many times I was fortunate to escape my own stupidity without permanent repercussions.



My best friend's parents were out of town. His dad had an oxy-acetylene rig in the garage. Around midnight one Saturday, we decided to fill a large trash bag with the mixed gases by setting up the torch with a nice blue flame, turning off the bottles so the torch went out, then placing the tip in the bag and turning on the bottles again.

I had opened up the bag first by swinging it through the air like one does when putting a new bag in the trash can. We filled the bag until it was nice and plump, then put it in the backseat of his mom's new Oldsmobile Delta 88 coupe and headed for the park. When we got there, we set it on top of some crumpled newspaper, lit the paper, and ran.

The explosion was epic, sounding like the result of an F-15 dropping a GBU-24 laser guided bomb on the park. It echoed nicely. Car alarms went off, porch lights clicked on, and we hauled ass. Back to the house to make another one, of course.

But this time we left the bag folded when filling it, so it expanded unevenly. When it was over half filled, my bud leaned over it to kinda flump it up a bit. That apparently triggered a static electricity spark, and the bag blew up. Ohh fuck, my ears were ringing and the air was filled with a dusty fog. There was an open bag of Portland cement on the floor right under where the bag was, and that shit went everywhere.

His dad was a retired Air Force Colonel, and ran a penny gumball machine business out of the garage. There were dozens of those glass ball vending units and huge quantities of boxed gumballs on the floor and on shelves. The cement dust had covered everything in the garage. It took us hours to clean up the mess.

While doing that we speculated on what would have happened if the first bag had blown up in his mom's car. We both agreed the Colonel would have killed us if the explosion hadn't. My ears quit ringing after a couple of days, it was a week for my fellow idiot.

And yeah, we may have been stoned at the time.

 

[napanutt]

Ever have a battery blow up in your face?

Twice.
I drove a tow truck just out of high school. First time touched the terminals “BAM”. Second time connected terminals, had the owner turn the ignition switch “BAM”.
Neither time I was hit but it was fucking loud and pieces of battery flew.
