From the podcasts, I know Paul Wheaton is a fan of Rob Torcellini's rocket mass heater autopsy video on youtube so maybe someone can let him know that Rob has a kickstarter going for 16 more days. A lot of permaculture folks are interested in aquaponics and even those that aren't will surely see aquaponics as a vector for increasing permaculture interest - and more infected brains. Also those just interested in rocket mass heaters may just want to support Rob for all the great content he has posted on youtube. I'm just a fan trying to spread the word. Thank you!
