Hi everyone! What's the next trend in vaporizers? I've done some search and found these: The AroMed Halogen Vaporizer The Oracle Infrared Vaporizer Then i started wondering what will be the next thing after that and came up with something like this: That's a 1st post so i wondered what to write about, actually... Anyway, i'll be glad if this turns out to be entertaining! My appologies otherwise: i didn't mean to bother or anything, i just hope i've chosen the right thread. Now my crude drawings might call for an explanation i guess. Well, the closed-loop temperature regulation problem is something which catched my attention early. It became quickly obvious that the bag was always located outside of the controller's feedback loop so i started thinking about finding a way to correct that. In the example from above, the bag is located inside a cavity coupled to a fan and that fan creates a vacuum to fill the bag whenever necessary. The heater injects hot air from the shortest path possible, when the target temperature is reached the vapour starts being collected and this brings back the temperature to a safe level. The heater can be tamed down by the servo-controller if it's still too hot and there's a fan in case more cooling is required. The vapour passes through a water filter and an ice cooler, then a radiator coupled to a fan finishes the conditioning... At that point the user has the option to draw the vapour directly by pluging his mouth tube to a valve, that valve also allows the bag to be emptied at the end of the vaporization cycle without removing it from its cavity for more convenience... The fan in the heater cavity cools the element when the machine is turned off, that cavity is insulated to avoid heat migration to the bag cavity but it's better being safe than sorry. In short, just enough heat is generated to vaporize the good stuff. The bag is filled only when the proper temperature is reached but there's the option to operate the machine semi-manually (without a bag, in emergency cases for example!)... This setup should be versatile enough to vaporize substances other than weed (e.g. salvia divinorum, etc.); please tell me what you think of my dream (imaginary) machine, your comments are most welcome!
