Wow, although I'm not really into BHO, this may solve a lot of the drawbacks to using butane - safety and cost. He even shows you the plans and parts on how to make one: Lil’ Terp Passive BHO Extractor - Passive Butane Extractor and Reclaimer. There's also a bigger model called the Mk III Terpenator. I like the name of his company too - "Skunk Pharm Research".
