As the title says, if you find one that especially resonates, post it here. Watched this last night ... Joel Salatin gets passionate at the Google campus:
i liked all of Geoff's videos he used to have available, but i don't keep links to things and i'm not sure what he's up to lately other than what he posted recently to the main page. i like to see how things have progressed with the site in Jordan and i remember what it was like when he started. as for topics of interest to check on i usually look for regreening the desert and the Sadhana forest in Haiti and elsewhere because i like to see how longer term projects go. www.weforest.org does not put up much videos, but i do like their efforts. JS made more money off touring and lecturing than farming... i've read his books, they're interesting, but mostly just rants about how various issues from regulations had to be dealt with. only a few bits of practical information per book. good thing they were quick reads. i don't consider him a permaculturist, but at least it is a step in farming in a better direction (not quite sustainable but closer than most commercial ag).
This guy built a wood gasifier to run his little truck ... I watched the build videos and they were fascinating. He gives an overview of the project here and drives the truck around to show it's capabilities. Apparently wood gas powered taxis were common in Paris during the second war and he's revived the technology.
Michael Pilarski talks about beneficial weeds in a young food forest, planted in Tonasket, Washington State (semi-arid climate). Would love to see an update of this plot of land.
