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.

The ArkFab Earthship Breaks Ground - Great News from the GTech Green Phoenix Project!

ArkFab's Earthship

Green Phoenix, an ArkFab umbrella project operating out of Georgia Tech, continues to develop innovative urban food production. They're putting out a call for volunteers to help with construction:

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.

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.

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.

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:

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.

LuciaStoves and Dual-Power Steam GenSets

LuciaStoves are dual-use biomass gasification stoves that have 96% combustion efficiency. 10 litres of wood pellets produce only 50 milliliters of ash... truly. When running in char mode the stoves produce biochar which is the only feasible method of carbon sequestration currently available. Biochar from millions of households using these simple stoves could reduce emissions through avoiding emissions from inefficient stoves and burying biochar in soil as a soil amendment by 40 million tons a year. Or about the amount of emissions from a small first world country such as Ireland.
