This concept will remain in the notebook for the foreseeable future, no time to develop it this year. But, I like to let my ideas brew for a good long time, so that's okay with me. I feel like it'd be a good idea to get some outside perspectives on this concept before I let it evolve any further. I'm really on the fence as to whether or not it's good...or trash.
I'm not too experienced with desktops, and while I see this as a portable desktop... It's still out of my realm. I could use a little help to figure out if this is even a realistic concept to begin with.
I don't have a super clear idea of what the end...thing... might look like, but I have the concept.
Here is a little drawing for reference, I'll explain what's going on below.
Here are some very rough possible vaporizer shapes. There are endless directions you could go, so this part is not really important, it's just an example.
The thing I like about this shape is that the herb chamber is loaded like a traditional pipe, which I find convenient. I think a WPA version would be a must.

The concept is to design a vaporizer that uses already available hotplates (designed for cooking, electrical soldering, lab work, etc.) as a source of heat. The hotplate would heat soak small heat batteries that are placed on top. These heat batteries are then moved from the hotplate and loaded into the vaporizer where the stored heat is used as a convection heat source.

The idea of "stored heat" is nothing new, the couch log and other vaporizers with a large heat store can be decoupled from their electrical cords to be used in a semi-portable way. There are also butane heated vapes like the elev8r that use stored heat for fully portable use.
I also think this is similar to a coil driven wand vape in that they also decouple the heater from the herb chamber.
Where my concept differs, I think, is the use of the hotplate.
So, why hotplate? In short, versatility. You have the option of using ANY hotplate that you can find, electric, gas, or charcoal. For stoves that do not have a smooth heated surface (butane stoves, for example), an aluminum or copper plate would be available for the heat batteries to sit on.
Here are just a few interesting options available.
On the electric front, I like these micro lab grade hotplates. These are built like tanks, UL certified, with fairly accurate analog temperature control. I like this one for its small size, with a 3.5" diameter plate. These are $300 new, but come up all the time on Ebay in the $50-$100 range. You'll find many similar lab grade hot plates out there that would be well suited. Some of the vintage ones look very cool.
Want something a bit more rustic?
The tea world is full of cool looking small stoves to be used with iron/clay kettles.
Want something smaller, with USB C, battery bank compatible, and digital temperature control?
For those of you with PID control boxes already, you can get hotplates that are compatible.
For gas, something like this would be neat.
Or for something super minimalist, charcoal.
Okay, but still want accurate temperature monitoring with these analog heat sources? Use a mini surface thermometer directly on the hotplate.

Advantages of the hotplate concept:
You can heat multiple heat batteries at the same time. By swapping out the heat battery every couple hits, you essentially have an endless supply of heat.
By using commercially available hotplates you get to take advantage of the economy of scale. Better and safer technology for cheaper.
A flat plate against a flat heat battery provides good heat conduction. Gravity keeps them in contact. No issues with different coefficients of thermal expansion.
The heat batteries remain at a constant temperature on the hotplate until you are ready to use them.
Great for groups, where everyone could have their own loaded herb chambers, but share a central hotplate with a handful of heat batteries.
Great for slower and longer sessions or heavy usage.
If using a butane heat source with a central hot spot, the temperature difference from the center of the hotplate to the edge could be used to our advantage. Heat batteries near the center would be hotter, and thus could be used for instant temp stepping.
__________
Now, the downsides. I'm sure there are many, but these are the obvious ones...
This is not the most economical way to use heat energy.
A coil driven wand vape (especially those with enclosed coils), uses most of the heat from the coil to heat the heater. A hotplate, on the other hand, wastes a lot of heat.
I don't think having a searing hot hotplate in your vape lounge is the safest thing. You would need to treat this thing as you would any other cooking stove, and I personally wouldn't feel comfortable leaving it on unattended.
Heat up time for the hotplate could be slow if using electric... or especially with charcoal, ha!
__________
So, what about a torch?
While it would certainly be possible, temperature control would require some practice.
I also think that there are better ways to make vaporizer if you want to only heat it with a torch.
_________
So, is this concept just pure madness setting in? Have I been in the workshop for too long?
If it seems like a decent concept, I'll just use this thread as a way to brainstorm and tease out the direction of where it could go. Maybe in a few years something will come of it.
