Hey Kent,
First off, thank you for this opportunity as guest article-author on your blog, and and additional thanks to yourself, and the others out there (Janzen, Kahn, Stiles, Pino, etc) who have been very helpful and supportive of what I’m doing (in regards to my 100% independent tiny housing book, and video/tv show).
As for the “Tiny Yellow House” series on youtube, the vegetable oil space heater (woodstove alternative) that was briefly shown in Episode #2 http://www.youtube.com/watch?v=LmR3kx660gw is something that I understand you (as well as I) have gotten a ton of email questions on.
All in all, since its rather difficult to just blurt out every constructive detail of the heater, I’ve sent you a hand sketched diagram of it instead, that was drawn as part of my follow-up to the book “Humble Homes, Simple Shacks…” which I’m still working on as we speak…er…as I type. The sketch, albeit busy and detail laden, should help give people the general idea I came up with, and I’m sure there ultimately will be twenty better ways to build this thing. All in all, while using a multi-wick system (more flames = more heat), this veggie-oil heater gives off a rather decent amount of heat that should be adequate for well-sealed tiny cabins, or should at least prolong your season or stay in a cabin, depending on your climate, naturally.
