Question about Stainless Steel tubing

[Yucca]

Thanks Yucca,
I wonder if the bit about magnetic stainless is true.

I don't know for sure, but i've seen losts of people on videos checking their pipes (especially in joe cells) using magnets, they like it when the magnet isn't attracted at all. I'd go for non magnetic stainless if i had the choice.

Hello all.  Forgive me for mistakes I'll make in being new to this forum (and to forums in general).  I apologize in advance if any of my questions are obvious or inappropriate but I am not an engineer nor an electronics guru of any sort.  I am - on my best day - an inventor that is fed up with the oil and energy situation.  With that said, I too am looking for a supplier of the 316L stainless steel tubes as used in the Meyer WFC.  I know this is an international forum so any supplier would need to be willing to ship to the U.S. if out of country.  And as with many inventors (especially those of us in a country with an incompetent idiot as a leader) I need to try to stretch my funds as far as they will go so the less I spend, the sooner I can get busy with this project.  I have read that the tube configuration seems to be more efficient by a considerable sum.  If there is any information otherwise, would someone please point me in the right direction?  I have done a search of the forums but I'm sure I will need to learn to be more effective to find the info I'm looking for.  I have also read a short piece that suggested titanium might be used in a plate configuration with better results than steel...?

Thank you in advance for your patience and assistance.

Stan says T304, RAVI says something else. I use 304 from www.speedymetals.com  Stan also demonstrated with plates for a variable gap. The tubes are configured to be waveguides which plates aren't so good at. Another example of a waveguide would be a cantenna. like this... http://www.cantenna.com/

Notice where the wire is connected to the can...

Thanks for the info Heair Bear.  I really appreciate your help.  With the 304 stainless, is it still critical to get it annealed or does it really matter with this alloy?  It seems many people just use it as shipped with good results.  As for the length, is there an optimal measurement for the tubes?  It seems if they're too long, you might lose useable area from all of the bubbles displacing the water as they rise towards the top - especially with such a small gap (the longer the pipe, the more bubbles, right?).

Thanks for the quick reply and the info.  This will help me get going.  I have some interesting ideas that I'm slow to share just yet as I don't want to look like a fool if I'm wrong.  If I'm not, I'll be sure to post all I learn.

Magentic stainless?maybe 409 or "304" and it can only be detected with a ceramic magnet other then that stainess should not have any magnetic properties. Try 316 stainless or Al6XN, Chromium, Hastiloy or  inconel or use distilled water. type stainess materials on the internet
