BioEnergy Dome in Arizona’s Bennett Freeze Area

bioenergy dome

This BioEnergy Dome lies in Arizona’s dune-pocketed plain at the foot of Dook’o’oosliid.  The unique one-of-a-kind BioEnergy Dome might be the answer to all kinds of questions.  It is a self-contained system that generates electricity emission-free, produces food and can recycle graywater- wastewater from all household sources except the toilet.

In addition to an Earth Day Peace Prayer and Concert scheduled here April 22-24, the BioEnergy Dome will be unveiled to locals and anyone else who might be interested.

It is Harold Begay, age 74, and Lillie Redsteer’s, age 77, home site, which is a “sprit-lead journey” according to one of the main sojourners, JoAnne Armenta.  Armenta came to the conclusion after working for the U.S. Department of Energy’s Clean Cities program, that the main obstacle to America’s implementation of clean energy technology was that so few people were trained to operate and maintain it.

She went back to school for a doctorate in educational leadership, moved from California to Arizona and found a nonprofit called Purpose Focused Alternative Education, which consults with manufacturers of green technology to create training curriculum.

Meanwhile Armenta connected with an anonymous woman who wanted to donate a BioEnergy dome to a Native American family, which were Redsteer and Begay.

Volunteer college students were at the Begay-Redsteer spread this week to dig the pond and install the dome. The couple is on their own to complete the project after next week’s Earth Day prayer and concert.  Begay and Redsteer have taken care of cattle and horses but never fish, which they will learn to do in the BioEnergy Dome.

The fish eat the duckweed and algae, which forms on the pond and their waste fertilizes the duckweed.  The pond has a filtration system that re-circulates the water, preventing oxygen depletion.

Then you cut the duckweed and feed it twice a day into a biomass-burning generator.  This produces enough electricity to power a one-family house and takes only one hour of maintenance per day.

The byproduct is mostly potash and micronutrients, which goes back into the water as fertilizer. The only emissions are carbon dioxide and water vapor, which are cycled back into the dome for the duckweed – and whatever else you want to plant in hydroponic racks alongside the pond.

Infrastructure in the Bennett Freeze area is lacking due to the Bennett Freeze, which the government placed in the 1980’s when none of the Navajo Nation was allowed to improve their homes until Congress approved a settlement between the Navajos and Hopis over the use of the partitioned land in 2009.

Now the Freeze is lifted, however, the people’s homes have deteriorated to the point no one can afford to repair them.
