As far as a pan liner for baking cookies and the like, this stuff is great. Quality is excellent and consistent throughout. It makes any pan non stick. But, what else can it be used for? Well, I recently am experimenting with energy production using water electrolysis to break down water into its hydrogen and oxygen components. Some of you might be familiar with the term HHO which creates a mixture of H and O gases out of water. This process creates a mixture of the two gasses which are highly combustible but cannot be stored because of this. However, if the two gasses could be kept separate and then stored, this creates a whole new realm of possibilities. Well, here is where the parchment paper comes in. I am testing it to separate the plus (+) and negative (-) electrodes and create a barrier to keep the two gasses from mixing as they form on each electrode. I have been testing it in several different electrolytes to see how it will hold up. So far results look favorable as far as holding up in various electrolytes. However, the low permeability of the parchment paper seems to add resistance to current flow between the electrodes which needs to be addressed further. So for now, the cookies will be using the bulk of the parchment paper. And, that's mm… mm… good!
