Salutations VaporOnly,
...vapocane/gnome type vape with metal instead of glass...
It happens i was about to post this picture in the VaporGenie dedicated thread but i'm thinking maybe it can be more productive here:
I've been curious about it but there doesn't seem to be much prospect for upgrades since it's about to stop being sold (only 1 left the last time i heard!), unless i'm mistaking of course. In any case, the Supreme is a very convenient example for what i'm about to suggest: take my right set of "aerated shield" & "foamy rock", treat it as a basic unit and imagine piling up duplicates inside some glass wand until it's full... What you'll have it a heat wand, you just need to find a way to heat those tiny metal shields in order to turn them into
radiators capable of heating air via pucks nearby, actually.
Well, aluminium turns out to be in used by PhyTherm composite alloys and these particular kitchen metal products have 2 main properties i find most appropriate for vaporizer applications:
1) Energy injection can be done magnetically (no wiring/parts to fail)
2) The alloy's Curie effect implements temperature self-stabilization!
Perhaps you can transpose my pile of metal/ceramic to a layout which matches your expectations better. I view a metal body heated from outside, in contact with metal bits inside, similar to those illustrated above... Definitely something not to be dropped on a toe while being in use!...
But that should work great, IMO. As a matter of fact i already got an idea on how to add inlet moisturization too.
...heat up in a matter of seconds...
An IH cooking plate can do that, IMHO. See for yourself, let imagination wander!
