Salutations Thomas Davie,
...don't want to go near a torch again...
There's more than 1 way to use a butane torch, as i found out myself, but i understand it's not matter for debate.
Once butane fire has been eliminated - including all other types of fires with it - euh... Lets hope you'll find a few remaining options that can meet your selection criteria. Which are...
Something like Dr Dabber Boost, Cloud V Electro or Kandypens Icon... ... ...electric dome... ...not sure if I like dabbing. ...portable setups any good? Powerful? Easy to operate (dexterity wise)? ... ...looking for opinions.
Indeed, actually i'd like to read those replies as well!
Does it have to be awfully slow?? How about quick-cycle toking, somewhat reminescent of dabs but yet much more conventional ultimately. I'm thinking of quick vaporizers based on a halogen lamp, for example. Those are still a bit slow by my own standards but the no-fire criteria is met, i ganrantee.
Next there's the determining trade-off which consists in putting portability on one side of the balance: this one can represent some heavy toll to pay, that might obscure the rest and especially if semi-portable will do.
As i recall there's the Venus, 2nd (newer updated) edition i think. That's one example. Then i don't know how versatile it can prove to be with all of the consumption formats mentioned above. It might be interesting to ask, though i don't expect lots of power from its 50 Watts lamp. In addition i don't suppose this heater can stand oily prints on its glass envelope a long while (...), so i wouldn't be surprized if that's not a favourite option with the Venus after all. Then other options would become more appealing, or maybe it's even possible the Venus changed more than i can imagine, etc.
Good day, have fun!!
