The Yeomans ‘Carbon Still’ is currently on display at Monash University Museum of Art “Shapes of Knowledge” exhibition. 

ALLAN Yeomans’ invention, the ‘Yeomans Carbon Still’, was designed by Mr Yeomans to measure the carbon content of soils.

The still is intended to be used by farmers as a means of quantifying the carbon sequestration performed through their agriculture practices.

In a future carbon economy, farmers could possibly be paid for drawing down carbon dioxide from the atmosphere through regenerative farming. According to Allan Yeomans, up until now soil carbon testing procedures have been complex and prohibitively expensive, meaning payments to farmers could be cancelled out by the cost of carbon measuring itself.

 

During the ‘Shapes of Knowledge’ exhibition presented by Shapes of Knowledge artist Lucas Ihlein at Monash University – Caulfield Campus, a working model of the Yeomans Carbon Still is on display and is being used to test the carbon content of soils of various farms throughout regional Victoria.

Excursions to collect the soil samples may involve Monash University students, scholars and members of the wider community and will double as opportunities for learning about regenerative farming processes more broadly.

Alongside these material investigations, public discussions will take place in the gallery involving engineers, climate scientists and carbon farming advocates about the potential viability (economic, legal, botanical) of an agricultural approach to carbon sequestration.

While the Yeomans Carbon Still is not yet an approved methodology for testing soil carbon, part of what Ihlein aims to do at MUMA is to explore the viability of getting the Carbon Still accredited by the Australian Government.

The still is currently on display at the Monash University, Caulfield Campus, Melbourne, Victoria until April 13, 2019. Opening hours: Tuesday to Friday: 10am-5pm and Saturdays: 12-5pm; Open to all. Cost free.

Yeomans LOI Soil “Carbon Still”© test takes two hours. Accepts huge 2,000 gram test sample. 550°C

“The urgent problem is getting rid of the excess carbon dioxide that’s already there. Soil can do that, emissions reductions must become zero, but that can be phased in over the next two to three decades,” Allan Yeomans.
