It is more so rapid cooling that is the fundamental problem with an on demand conduction vape.
Can't they use the same rapid cooling technology that's in the convection vapes?
Yeah just look at the designs, we finally have it with the firewood 7 and on, BAK is less on demand but can be thanks to the removable chambers and full power capability, I think it's pretty easy to see why mainstream devices are the way they are, the mass production, but Solo 3 is a pretty solid one
(The title of your post says why aren't there more on-demand convection but then your post seems to describe the question being why isn't there more on-demand conduction? So that is what I answered, but convection on demand would be a different response)
Wow yes you're correct about the title. Sorry I'm a little sleep deprived right now
The Firewood came up in my search and looks great, though apparently not available right now. The BAK I'd never heard of and looks gorgeous, but also seemingly unavailable. I've seen the Solo 3 mentioned a few times, maybe I'll look into that more seriously.
Magic flight launch box is your answer
Haha I guess that basically is what I want. That's what we had back in college but I guess I thought maybe there'd be something new since then. But also I suppose if what I want is simple, maybe it would be something that was invented a while ago
To me, the joint smoking experience would be session. A one hitter would be on demand.
The Vaponic is a conduction / convection / radiation hybrid device and definetly can be used on demand like a one hitter. (It's a microdoser though, maybe not for everyone)
Hmm maybe? My only reservation is usually I'd like to hit a joint on and off for 15-20 minutes, my image of a session vape is that it extracts it all at once. Is there a way to stretch it out over time?
on demand is tough - that's what a BIC does so well for a joint. i can get the heater to 400°F in 10 seconds - still 10 times slower than a BIC ... but the heat transfer to the herb is too slow ... the herb needs a 2 minute heat soak at just below vape temp so that a draw can cause the final 50°F temp increase that releases the vapor.
i'll be a session man until space lasers can do the job.
Interesting, I'd never considered about the time it takes for the heat to get to the herb. I guess is that what's cool about convection that heat can get to it quicker? And are there any devices that can hold at that just below vaping temp or quicker conduction?
