NaOH is one of the most used chemicals all over the world. I need it for a few reactions but cannot get my hands on high concentrated solutions or pure crystals(bloody switzerland...). I tried the good old meathod which involes woad ash and running water through it. I got some PH 11 solution, which is not strong eanoth for my needs. Here is my question; Would it be worth while to make a simple electrolosis cell and to make NaOH by the electrolosis of NaCl solution, or would the time and money consumed by such a cell be out of proportion?

There are already a few threads on this matter if you do a quick search, which highlight the electrolysis processes. As for your ash method, if you already got some dilute solution out you could just boil it down.

I could make it from calcium carbonate but i am not sure where i would be getting K2CO3. Perhaps I could some how get Na2CO3 from sodium bicarbonate and then go from there?

If I remember correctly, you can produce Na2CO3 by a simple decomposition reaction by boiling a NaHCO3 and water solution.
That would work - wiki says it decomposes around 50C.
I understand you are in Switzerland, but I imagine that even the Swiss encounter slow/clogged drains occasionally . . . look around for some drain openers - some even list NaOH as one of the ingredients right on the bottle. I'm assuming you've thought of this but keep looking - you're bound to find something eventually.

The extract of wood ash is largely K2CO3 solution. Na2CO3 would work too but, as has been said, you might want to keep looking. What do you want it for?

Well i need it mainly to produce hydrogen and as a general reagent. The swiss love doign all sorts of in practical and expensive things. First of all once your drain cloggs you call the clogged drain expert, he will the look at the drain for 2hours and then tell you this is a serisous case and needs serious treatment, next he will bring in a high pressure air tank and will stick a rubber bong in your drain, he will open the valve and 50bar air will push the hair down the drain, he will notice that he only worsened the situation and start taking the drain apart blowing air into every pipe, then he will say that a chemical solution will be needed and so will go get his special mix of highly toxic sodium hydroxide. He will call in an expert for unclogging drains with chemicals and they will try to unclog the drain. Next they will agree that the pneumatic solution was best and will blow air into the drain. From all possible angles.
After 500$ and a few weeks the drain will be fixed...you understand don't you?
