Making Biodigesters, Aquaponics, and Other Self Sufficient Systems from Everyday Materials at ECHO

Continuing my tour of ECHO Farm, this time I talk about the demonstrations of their sustainable systems. So many incredible things to see at ECHO. Rocket stoves, water filters, aquaponic systems, biodigesters, water heating, oil pressing, and many other appropriate technologies mostly made from reused and reclaimed materials. You can also find open source directions and how to info about making all of these sustainable systems at their website
