Purple-Days: Regarding the "20th Century Design" photograph showing brass and steel PD diffusers, are these the main heaters (heat sinks/exchangers)? Or are these accessory (slip on top) aromatherapy diffusers? Regarding what I presume is the current 72-finned stainless steel heat...

magicflight: You neglected to mention that through the LB's design, besides optimizing infra-red heating, you have apparently tried to attain as much convection as possible. The air flow appears to be rather precisely designed, with air flow above and below the load, and the induced swirling...

With your full disclosures (publication) on FC ( prior art disclosure), you no longer can receive patents in most every country in the world, except the U.S., where you have 1 year from first public disclosure to file for a patent. Do you have a real (patentable) breakthrough in small heater...

Can you relate any of your experience purchasing this heater? When I searched, I could not find any stock low-voltage (12-14 volt) cartridge heaters anywhere, with companies agreeing that this is what they would expect (no real market). Was this heater from stock or a custom order? About how...

I particularly like the compact unit. It looks like it could even be used as a hand-held? Could you post pictures of the units as they are used? For example, what are you inhaling through and how does it connect to the heaters? ?

High purity, non-toxic latex (natural rubber) is probably going to melt or at least lose its shape at temperatures likely to be encountered with vaporizers. I would presume that natural rubber products that can withstand vaporization temperatures contains additives, including toxic...

Everyone seems to be ignoring Teflon (PTFE) tubing. Any reason for this? Other than generally costing more than silicone tubing, virgin PTFE/Teflon seems to offer some advantages for vaporizer use. It is much smoother (more sanitary and cleanable) and unlike silicone, dirt will not stick to...

Depending on particle size, shape, how dry, fluffy, etc. (how densely packed) the herb is and how high the stem/tube is filled, the amount (weight) held by the stem/tube could vary greatly. Is there any consensus on how much a stem/tube generally holds, in terms of weight? Has anyone...

THC and cannabinoid molecules are inherently very sticky, sticking (by adsorption) to themselves and to other plant components, particularly cellulose. Thus, what we refer to as vaporization of herbal material is, more technically, thermal desorption, using a blast of heated air to violently...

CORRECTION: The link for the example jump starter was for connecting to another vehicle. What is needed is a battery jump starter, such as http://www.amazon.com/Black-Decker-VEC010BD-Start-Starter/dp/B000E1HAIK/ref=sr_1_1?ie=UTF8&s=automotive&qid=1250910480&sr=8-1 This even has a "12 volt DC...

A fail-safe and probably the best option is to get a basic car jump start battery device (or a plain battery with similar cranking power). So even if your vehicle battery runs down, you can always jump start your car. For example, see...

While on the subject of power requirements to heat air, does anyone know the formulas for the amount of power stored and delivered by a heat sink/exchanger to passing air? The Purple Days (PD) at <10 watts, my prototype vaporizer at <25 watts and other low-power convection vaporizers with a...

They aren't exactly heat guns, but check out digital air heaters (solder rework stations), such as http://www.circuitspecialists.com/prod.itml/icOid/7343 This has a digital controlled and read-out hot air gun, air flow rate display and adjustment, readily adapted nozzles (with many others...

Thank you very much for posting this data. It will be useful for anyone designing a vaporizer, and is a significant contribution to the community. This is the first empirical data I have seen comparing actual hit length and average air flow rates. That you also include the amount of heat...

Maybe asserting ones rights and saying no when asked "May I look in your car?" works in some places, but in my area (northeastern U.S.), this response is almost guaranteed to get your car searched and get yourself detained on site, and who knows what from there. Here, if they've stopped you...

I like that. It could pass as a model of a portable solar-powered battery charger (with electronics going where the screen is).

In my view, telling this to a skeptical policeman or other person in authority would be worse than simply saying "I don't know." Referring to incense and burning should just make someone more suspicious. You would be explicitly admitting that the LB is used for what many or most would...

Can anyone suggest names/explanations for what the Launch Box is, other than its intended use? For example, if your car were being searched and you were asked, "What's this?," what would you say?

It's got solid-state variable temperature and air speed controls, an air flow meter, a built in external arm/holder, probably more heating power than needed for vaporization, has lots of attachments that look likely to interface with parts from existing vaporizers, has a ceramic heating element...

Another way to cut down on coughing (due to immediate membrane irritation) is to thoroughly dry (heat) your material such that you drive off (evaporate) most or all of the non-active lower molecular weight aromatics (terpenes, phenolics, etc). This may mean using a finer powder, heating it...
