Haven't been here in a while, any developments?
The Metal
tanks I've seen are not Painted, but are Anodized Aluminum, which should be safe to use, though I'd still like (prefer) one that has not been anodized a color!!!
Well, mine is black, so I assume it is painted, or something like that. It does seem to be holding up though, over the last few months.
But I still constantly run the tank dry coz I can't get used to how quickly the ViVi Nova eats juice, seems arbitrary as well, I don't know where it all goes!
It's like it disappears sometimes.
I like the glass over metal idea, I wonder if I could send the tube off to a glass blower to have it done, I'm gonna have a look around this week to see if I can find anyone who can do it. Might have to see if it's possible to also shave down the outside to make it thinner, so that the glass is flush with the rest of it.
Also, not sure if this was mentioned as I can't remember the thread correctly, but what about "clear aluminium"
http://en.wikipedia.org/wiki/Aluminium_oxynitride ?
Or even
http://en.wikipedia.org/wiki/Transparent_ceramics since it can be made thin as well.
Would be expensive, but worth it IMO.
