Aquaculture and aquaponics on a family-sized scale in Maui, Hawaii. They are growing mainly tilapia whose waste they filter out and use to grow food plants.

Danny Rhodes of Desert Fungi in Velarde, New Mexico gives us a detailed tour of his greenhouse mushroom farm operation. I found the wet wall/swamp cooler system he rigged to control the temperature in his mushroom growing greenhouse in the summer especially interesting. Danny produces between 100-150 lbs of Oyster, Shiitake, and Lion’s Mane Mushrooms per week, most of which he sells at the Santa Fe Farmer’s Market and direct to local restaurants.
This video has us meeting the Simonsens, in Nebraska, who grow sorghum. They use no-till rotational planting. They mill sorghum flour themselves and sell it direct through mail order. The grit left over from the milling gets fed to their livestock.
This mini documentary is a bit rough because it’s old and grainy and in German (narration) and French with English subtitles, but it is worth watching because of the amazing energy innovation it shows.
“Jean Pain – A French innovator who developed a compost based bio energy system that produced 100% of his energy needs. He heated water to 60 degrees celsius at a rate of 4 litres a minute which he used for washing and heating. He also distilled enough methane to run an electricity generator, cooking elements, and power his truck. This method of creating usable energy from composting materials has come to be known as Jean Pain Composting, or the Jean Pain Method.”
Will Allen walks us through the Growing Power farm operation in Milwaukee, Wisconsin. They use vertical growing techniques to maximize yields and growing space for vegetables and mushrooms and they also produce tilapia (in heated tanks) and yellow perch (a lake fish that can no longer be fished for in many places because of contamination) in unheated tanks. The greenhouse producing all of this food is heated by compost.
