great posts in the 'alternatives to butane, and my solar legionair's salute to all solar hitters.

however, it needs to be stressed that solar vaping is not just a substitute to a butane lighter (although it is that, too) - it is a vaporizer that is natural, inexpensive, 'cordless' (and no batteries required), endlessly reusable, cheap, clean, compact, light-weight, wind-proof, water-proof, with an 'instant trigger' and precision fire and heat control - and solar vaping should be used that way to get the full efficiency. otherwise, only the first hit is vapor (or very clean smoke that is minimally iritating to the throat), but the rest is regular smoking if the herb catches fire and burns itself.
