Urgent Evoke

A crash course in changing the world.

My sketch of how it could work.

I started thinking seriously about the kind of scale of intervention that might allow us to get back to 350 ppm CO2, and I did a calculation in this post following our useful discussion. Planetary management is a reality now, we humans are just doing it very badly at the moment. Step up!

Intensive worm beds are fed from inedible green waste scraps. (Lots of research exists about what worms will digest and what their outputs are.) The worm bed needs to be encased in a gas containment membrane to make sure that the greenhouse gas N2O doesn't escape into the atmosphere. (I've emailed some specialists about what kind of technical specification might be necessary for this. I imagine it will need close monitoring and that might be the most labour-intensive part of the project!)

The exhaust air from above the worm beds is drawn out through a treatment chamber (centre of sketch). N2O can be harmlessly decomposed to N2 + O2 through heat or catalysis so something like that is in the treatment chamber. Another option could be purely natural biological treament, for example venting the exhaust gases through beds containing high levels of denitrifying microbes.

The treated air goes out into a greenhouse, which also contains plants growing in the worm casts. Worm casts, the fixed carbon and treated compost that the worms make, is excellent as a growing medium. The air exhaust is monitored a second time when it vents from the greenhouse to make sure we have got rid of the N2O.

Although N2O is a very useful gas - it has medical and propellant applications - the partial pressure will probably be much too low in the outflow from the worm beds to make it possible to harvest it. Any ideas about how to harvest it very welcome!

Wow-- what a great post, Starling! I especially like the idea of using a biological treatment system. It reminds me very much of the work done in the '70's by John Todd (and written about by his wife, Nancy Jack Todd) in their old organization, The New Alchemy Institute, and also the Integral Urban House and Farralones Institute. The scientists here were all interested in developing sustainable cycles, where the waste product of one organism was used to enrich the environment of another, whose waste products in turn supported others, etc. Sort of an early precursor of 'Biomimicry'.

Another great post from Agent Starling!! +1 for creativity

May I suggest you to look at how organic "bio-bees" combats pests without pesticides in Israel and how another New York based enterprise has productively used worms to create natural composts.

Thanks for the links Sarah and Rahul :)

Fourth of July on the Lake

This past weekend was the annual celebration at the lake house in Connecticut. It is amazing that the lake is still so clear and beautiful after all these years. The watershed association has done a wonderful job protecting these waters from the damaging effects of development.The wood grill was finally ready to cook on, so we didn't miss the propane tank fueled grill anymore. The food actually tasted fresher than in the past and was easy to keep fueled.Dad was very proud of the solar hybrid…See More

Stinging Nettle

In this blog post I will focus on a plant that is abundant in our nature, and which is immensely nutritious. It's of course the Stinging Nettle. Let's start with the chemical constituents of this plant:37 % Non-Nitrogen-Extracts19 - 29 % Ash9 - 21 % Fiber4 % Fat22 % ProteinOnce the leaves are drid, their protein content can reach an astounding 40 %, which is much higher than beef, which even under the best of circ***tances can never exceed 31 % protein. In addition the Stinging Nettle consists…See More

The meal

It is 7'oclock, I was late home from work due to an assignment that i wanted to get ahead on. By the time I get home I am feeling extremley tired and I cannot be bothered to make a proper meal. I walk to the fridge and open it to see what there is for me to eat. All of the out of date foodstuffs have been automaticaly thrown away by the fridge, they will be recycled tomorrow as animal feed or something. I see i have organic local eggs and some local cheese. Foods are vacc** sealded for easy…See More

FutureToday is 2020/1/1. It is just like yesterday. The war is still continuing. It has started since 2010. In 2010, that year was a horrible year. Almost every energy ran out. Every country’s governments were crushed down at the same time. There were riots everywhere. All of the big company’s bosses were killed xdeadx in the riots. Troops fought each other everywhere. Food was bought up xawayx at once. There were no more food supplies in any shops. The economy was all crushed down. All the…See More

public servants

The exchange works directly for state and public workers and servants. It gives them credit in exchange for the amount of public work they contribute to the community. The more constructive they are based off a base rate the more credit they recieve.
