The Sound of Science: towards robust monitoring of the optic and acoustic environments

There is a companion article at TopOc which takes a more detailed look at the science of environmental sound and light

If you look up at the sky, and it seems to glow orange and drown out the stars, you're looking at light pollution.

CO2 Trouble: Arkfab's First Feature Length Report

A companion article at TopOc discusses the importance of correct documentation and an unexpected observation I made while crunching numbers for this research.

Announcing ArkFab's First Working Paper : Thermodynamics and Poker

There's a more technically oriented discussion at TopOc

The current version of the paper can be found here.

Tragic News

Liam Rattray, who founded the ArkFab project, died on May 30. A drunk driver hit his motorcycle, throwing him into oncoming traffic. The whole story is here.

Ocean Acidification: A Short Video

At a local community center, ArkFab gives a short talk and chemistry demonstration about the environmental chemistry of carbon dioxide.

The Political Economy of Antiscience

When it became clear that CFCs, a class of halocarbon refrigerant, were degrading the layer of ozone which protects us from ultraviolet radiation, the industries manufacturing the halocarbons began to turn their gears:

Experimental Flat-Panel Photobioreactor

With funding from the Center for Biologically Inspired Design I designed and built an open source experimental algae photobioreactor. Open Source Hardware plans will be released when I complete the research report.

How to grow gourmet mushrooms in your back yard

On February 20th this year I seeded a 20ft. garden bed mulched with 30lbs of wheat straw with two quarts of Pleurotus ostreatus (Oyster) mushroom spawn. Less than 8 weeks later on April 13th I harvested my first flush of mushrooms, about three ounces. This is how I did it with some notes on you too can easily incorporate tasty mushrooms into your home garden.

SPORE v2... for post-disaster recovery?

Once we've built SPORE v2 we will be able to begin considering the application of similar kinds of systems to post-disaster recover scenarios, but I can't help myself from considering the possibility right now after hearing what has happened in Japan.

SPORE v2: a vertical farming facility for mushroom cultivation

The original hoophouse designs for the ArkFab farm have an estimated lifetime of only four years... and they don't stack. I took the multistage bioconversion process from these first designs and incorporated it into a standard repurposed shipping container structure with an estimated lifetime of 10 years.

DIY Spectro II

There is a companion article focussing on the technical details of this project over at TopologicOceans

At long last, second generation DIY spectro has arrived!

The spectrophotometer. Yes, that is an invisibility cloak. You can't see the stuff that's under it can you? Then that stuff is invisible!

Garage Mycology

Great news! ArkFab is a finalist in the Georgia Tech Ideas 2 Serve Business Competition. This makes us eligible for a $2,000 prize that could help us move on from our garage. Like many start-ups we're using the space and resources we have to make our way. ArkFab currently operates a small wet lab and a few garden plots where my fellow collective members Nicole Bluh, Vincent Castillenti, and I are experimenting with natural and intensive mushroom cultivation. Here is a photo tour of our "garage" facilities:

Building Capacity for Vertical Farming in Atlanta

We're developing a vertical farming capacity building program in Atlanta. Our greenhouses can provide the Truly Living Well Wheat Street Garden, a training center for urban agriculture in downtown Atlanta, with capabilities for mushroom cultivation and eventually, through integrating systems, aquaponics production. Our multistage bioconversion process cultivates gourmet mushrooms, vegetables, and fish by upcycling organic waste streams from local businesses.

The ArkFab Open Source Living Machine Series

Living machines are conventionally known to be engineered biological systems that treat waste water. ArkFab living machines extend this definition to convert any kind of organic waste into value-added products, like food, fuel, biomaterials, or ecosystem services like wastewater treatment.
