This Aussie’s ‘rocket stove’ cuts pollution in the Himalayas
Russell Collins, a tinkerer by nature, knew he was onto something when he stumbled across a way to get rid of the smoke killing more people in India than HIV, TB and Malaria combined. (WHO stats link below).
Based in the small coastal town of Byron Bay, Australia, Russell had heard about the efficiency of a technology known as ‘Rocket Stove’ and wondered if it could be adapted to the Himalayas, where he had been running tours for over 25 years.
“It was basically a hobby that got me out of the office and into the shed for a few hours each week. I loved the process of welding and experimenting to see what would work. When something actually did work, I was as surprised as anyone!”
Russell’s ambition was to reduce deforestation in the Himalayas by making a combustion heater that was more efficient than traditional designs. The challenge was to make something that suited the cultural context where women would sit low to the ground to cook on top of a wood fired heater throughout the long cold winters. “Height was the key challenge. Rocket Stoves are typically quite large, so the innovations I developed were focussed on how to make it work in a low-height format to suit the way women sit whilst cooking, having a view of the children in the warm winter room which the whole family inhabits during the cold winter months.”
After 2 years of trial and error, Russell came up with a prototype he felt was ready for testing in the Himalayas. “At this point I got lucky. A guy I had met in the Himalayas 13 years previously heard what I was doing and offered to fund me whilst I set up prototyping and development in India. This support enabled me to quit my other work and focus exclusively on developing the technology.”
That was in 2016. Now, less than 3 years later, the social enterprise Himalayan Rocket Stove Pvt Ltd has made and sold more than 700 clean burning high efficiency combustion heaters with an average wood savings of 50% and a reduction in pollution of 90%. Russell is now interested to talk to social impact investors to scale the project to reach the wider Himalayan belt as well as global markets. “I have been approached by people from Chile, Tibet and Mongolia, all looking for us to set up factories to make and sell the combustion heaters in their regions.”
By dramatically reducing both fuel demand and pollution issues in a low-cost format, we have found a way to make a positive impact on so many levels. Each stove in the field reduces CO2 released to the atmosphere by 2-3 tonnes per year.”
