Students at the Marin City Conscious Kitchen Community Garden at Martin Luther King Academy and the Sausalito New Village School are participants in 2050kids Cookstove Challenge, using infographics to build a biochar producing cookstove. The Challenge will help determine if the project would work in communities around the world which are most threatened by climate change.
The stove is made from tin cans using basic hand tools and other simple materials and produces biochar, a type of charcoal first used by Native Americans as a soil amendment thousands of years ago. Scientists have discovered that this simple charcoal, if used correctly, has the ability to store harmful carbon for thousands of years.
The infographics to construct, assemble, and use the cookstove employ universal symbols and images to guide individuals through the processes of building, assembling, and using the cookstove.
“We’re working on this project from the perspective of helping and ‘reclaiming’ ancient practices rather than the ‘pitch’ or angle of doom and gloom of our future without remediation,” says New Village School teacher Gabe Cohen.
The Cookstove Challenge began last fall with a cookoff between boy scouts from Elk Grove, CA. 2050kids plans to expand the challenge to other communities in the North and East Bay. They will be holding their first fundraiser on Earth Day, April 22 at Yoga of Sausalito.
Students at the Marin City location, who begin work on constructing cookstoves next week, last month prepared test garden plots with organic biochar compost donated by
WM EarthCare Landscape Center in Novato. They will be planting tomato starters in both biochar and untreated beds to determine if the biochar compost impacts the growth and production of the plants.
Why Biochar?
By 2050, climate change from carbon emissions is expected to drastically alter the lives of some 9.7 billion people. In the decisions all of us make today, we need to find ways to reduce the levels of carbon in the atmosphere. This includes rethinking how we grow food, how we manage forests and farmlands, and even how we cook our meals.
Biochar could be a game changer in addressing climate change. Experts suggest that it has the potential to store one gigaton of carbon per year by 2050.
Some 3 billion people worldwide use polluting cookstoves as their primary source of heating food. Household air pollution is a major global health problem. This cookstove will not address these global health problems: It burns for about 30 minutes, enough time to cook a simple meal.
2050kids is using it as an educational tool to engage people in a hands on learning experience about how a simple cookstove can be used to produce biochar, improve their soil, and store carbon.
(In the diagram to the right, the biochar is what remains after the burn. An airtight top must be placed on the pan below the stove to ensure the char is not exposed to oxygen. This biochar can be added to new compost.)
If you are interested in accessing the infographics, let me know. We’d love folks to help us test drive this entire process. Eventually, the entire pamphlet will be downloadable from the 2050kids website.
Kitchen Table Kibitzing is a community series for those who wish to share part of the evening around a virtual kitchen table with readers of Daily Kos who aren’t throwing pies at one another. Drop by and tell us about your weather, your garden, or what you cooked for supper. Newcomers may notice that many who post diaries and comments in this series already know one another to some degree, but we welcome guests at our kitchen table, and hope to make some new friends as well.
Join the People’s Climate Movement this April 29th in Washington, D.C. and across the country to stand up for our communities and climate.
Throughout the first 100 days in office, the People's Climate Movement is organizing a country-wide arc of action, culminating on April 29th in Washington DC in a powerful mobilization to unite all of our movements.
To change everything, we need everyone!
