In the MFLB discussion that has grown weeds for a while now, some serious and very helpful advice pointed me to the VapMan setup. I like it a lot and will probably buy the full kit at some point. But it had me thinking and something troubling came to mind... also fueled by another discussion as to appropriate 'globes'. Picture this (since I am still working on my 50-gazillion posts before posting images); a) Take a light bulb... no internal coating, good spherical size, and a standard fitting. Key design element is 'thin glass for thermal response'. Go in through the metal end and scavenge out the innards. b) Take a motor jig of sorts and rotate the bulb slowly. This is a critical element in this discussion... this becomes the 'regulator'. c) Place a heater unit, similar output to a heat gun with minimal velocity but a good solid instant heat source and place it below the light bulb. d) Now affix a mouthpiece that; 1) ...has a carburetor that extends into the bulb [for fresh air]. 2) ...is fixed to a base [not rotating]. 3) ...uses a technique to allows a decent 'vacuum' from a draw although not physically connected [ref: 2-stroke engine chamber pressure]. Okay, so the rotating joints in our venture is not simple and that is where the true development would reside but the type of unit I am describing is available for labs (evaporators). This is mostly a consideration for herb because things get a whole lot simpler for other source matter as things don't have to spin. Why the spin? 'roasting'... That is what I am envisioning. You set a tumble speed and a heat range and the thin glass will quickly develop vapor and also quickly cool down as it spins away from the heat source. Of course, a lot of development could make this a really cool and sought after device. But considering I hadn't seen anything that fits this description in herb vaping, I though it a novel consideration. What say you?
