hydrogen lighter

 electrolysis of water

I always hate it when my lighter runs out of whatever is in that damn thing. here's a solution that would allow you to simply fill it back up with water and some salt rather than run down to the store. When you press down on that red thing on the top it would activate the battery. This 1.5V battery and some small graphite rods could separate the hydrogen and oxygen from the water. Then you'd use the flint at the top to ignite them. I don't know if the flow of these gases would be enough to keep the flame going, but that's why this idea is half baked.

or would it just explode?

       It wouldn't "just" explode, but it would certainly have the potential to do so, hence [+] for dangerously inadvisable and reckless production of a stoic fuel/oxidiser system in a confined space and the presence of electricity.

       I just let [8th] make these decisions for me, as he knows best!

       Could the electrolysis function be incorporated into a base station of sorts, so that you can simply "charge" your lighter whenever it gets low?

       ooo, being able to charge the lighter would be even better. Is there any way to keep the oxygen and hydrogen from forming Oxyhydrogen? because if so I might actually try and make this

       Wouldn't you have to run down to the store and get new batteries?

       [+] for totally inadvisable mixing of hydrogen, oxygen and sparks

       I'd like a lighter with the power of dihydrogen monoxide, but I am frightened about this chemical. Hundreds of people die every day around the globe by ingesting this!

       CP, surely di-H mono-O is more toxic when inhaled than when ingested, no?
—goldbb, Jul 05 2010
   

       Excess of either is fatal.

       Excess of ether is fatal.
