Dr. Mercola Discusses Chickens with Joel Salatin at Polyface Farm

Movable chiciken coops used in permaculture


Internationally renowned natural health physician and founder, Dr. Joseph Mercola and Joel Salatin of Polyface Farm, show how chicken live on the Polyface Farm. Joel’s techniques grow healthy chickens and develop top soil in a balanced manner. Using a mix of chickens, cattle, pigs, and turkeys the technique has transformed his family’s land from a barren rocky plot to a robust pasture with over 8″ of perfect topsoil. His methods are scalable and can be implemented in everything from backyards to huge tracts of land.

An Excellent Example of a Well Built Aquaponics System

Nelson's Aquaponic System


This large scale Aquaponic system is designed from the A-Frame Deep Water Culture Column (ADWCC) Prototype designed by Nelson Mmbando, 256 square feet foot print capable of producing approximately 400 heads of lettuce every two weeks. This system also incorporates vermiculture to break down food waste and introduces the nutrients back into the system.

Nelson utilizes the concepts he fine tuned during his thesis project and is a great example of a well thought out aquaponics system the expands the standard model into vermiculture.

Introduction to Black Soldier Fly Larvae

The black soldier fly is a widespread fly whose larvae are commonly found in compost heaps. Larvae are also sometimes found in carrion. This is fascinating as they are able to break down animal matter where other composting techniques fail.

When the larvae have completed their larval development, they enter a stage called “prepupae” wherein they cease to eat, they empty their gut, their mouth parts change to an appendage that aids climbing, and they seek a dry, sheltered area to pupate. This migration instinct is utilized by grub composting bins to self-harvest the mature larvae. These containers have ramps or holes on the sides to allow the prepupae to climb out of the composter and drop into a collection area.

Black soldier fly larvae (BSFL) may be used in manure management, for house fly control and for the bioconversion of organic waste material. Mature larvae and prepupae raised in manure management and waste bioconversion operations may also be used to supplement animal feeds. The larvae are highly efficient in converting proteins, containing up to 42% of protein, and a lot of calcium and aminoacids. In 432 hours, 1 gram of black soldier fly eggs turns into 2.4 kilograms of protein.

Larvae are sold as feeders for owners of chickens, herptiles and tropical fish, or as composting grubs. They store high levels of calcium for future pupation which is also beneficial.

Invelox Wind Turbine


[Full Story]

This wind turbine makes use of funnels and tubes to harness wind energy. The Invelox turbine is capable of harnessing wind energy from winds which are as slow as 2mph and that is made possible by directing the wind into a funnel and then channeling it via a tube to the generator of turbine located on ground. Usually the wind turbine generator is situated on top of the tower. However, Invelox keeps the generator on ground and directs wind to it. The other obvious difference being that in conventional methods, wind energy is harnessed when it passes through the blades. With this design, that wind is captured via a funnel that leads to the generator.
