What do you expect to do, open the valve, flick a Bic, and the water is going to start flowing? Come on. This was a fun nonsensical thread, and you're now trying to turn it into a magic trick rather than goofy science. You have to capture the flame's exhaust, pressurize it, and whatever other sciencey stuff to get the waste into a liquid

> pressurize it

You "just" have to capture and cool it down.

I mean, it's completely outside of viability, but it's not breaking ground science. You could do it perfectly well in a lab (if you had any reason to).

[dylan604]

There's a lot of things that can be done in a lab, but bringing it to the real world is totally different. Nevermind fitting this in the original concept of backpacking

Liquid methane can use normal thermos technology, with the venting fed through a burner to create your water.

[marcosdumay]

Ouch. No, go read the thread again.

You can turn methane into water in theory. And you can technically do it in a lab (even though the easiest way by far to do it uses a lot of water). You can't do it on your backpack.

The way I was picturing it, you light the balloon and, besides some burn marks and a boom heard miles away, water appears in its place and falls into a bucket you placed below.

Not like I know how this stuff works. Someone says methane turns into water when burned, I imagine based on farts that it floats like in a nice balloon or Hindenburg, I figure this do be how this was intended ¯\_(:))_/¯
