I am no sientist when it comes to burn times and boiling water.
This stove dose boil 2 cups of water within a resonabul amount of time.
The real selling point of this stove is its strength.
This stove will hold up to a lot more abuse than other stoves.
Here is a test I did with it.

I wanted to try and convey how tough this stove really is compared to a regular pepsi stove.
Before
(please excuse the shoddy craftsmanship of the pepsi stove, Knowing it was doomed I didn't feel like making it pretty)

During
I couldnt get a pic of it totaly on top of the stove because the tire swallowed it up and you couldn't see it.


After

Sorry pepsi stove, you loose frown

I have two built and ready to go.
$25 and I will take care of shipping
