Alcohol Stoves

you can smash up side walk chalk and use a layer of that instead of fiberglass

how much money would you want for all of them

I tried one today when the power went off, used rubbing alcohol, open chimney type with jets at the top, placed pot directly on stove. Rubbing alcohol (70%) did OK, but not great, was able to heat up a can of beans and pork though.  Need bettter fuel and lower design, pot was a little tippy. Even my slapped together one did OK for a first try, now I want to build a better one and get more style points next time.

What's a "desing"?

Why should the can explode if you don't put the screw in? is it a build up of some kind of pressure? I mean if your using alcohol that should not happen, if gasoline the fumes could build up and blow up like that. Just woundering why that happens when you dont put on the screw. My friend and i want to make one, have any suggestions for first timers besides screw in the screw?

The Explode is when the Air and Fuel Vapours are at optimal mix inside the can.
Its like 10% Fuel Vapour 90% Air

It only needs flame to make it inside the can to ignite this rich vapours mix and you get a fireball inside the can that will force its way out. 9:26 is what happens when the gas mix hits perfect inside the can and when a flame makes it inside the can due to incomplete burn on the outside (Ie The flame was sucked into the can via the ignited side of the can)

More cont... The can turns into a very crude Combustion Engine which is why it shot 2 feet across the floor

i dont bother with screw. i make 5 pin holes and fill in middle. then put penny over. it wont explode. i have had one "explode" but all it did was pop off fast! put fiberglass inside the can!

I just use gasline antifreeze so whatever that is. Its really easy to get at most stores.

nice video.
