1 The Basic Mechanisms of the Rocket Stove. With the lessons from people like Rok Oblak, Richard Stanley and the Aprovecho Institute the author began learning to build the holey roket stove in his workshop at Daet, Camarines Norte. With sheer perseverance and amidst scarcity, he was able to create several models and delivered skills training to poor people in Camarines Norte, Sorsogon and recently in Bulacan.

2. Among the many feedbacks from the users are the limitation of the holey roket stove in terms of (1) fragility in handling and (2) capacity to receive bigger loads when cooking for bigger occasions and events and for food business. In response, one of the models was picked up for reinforcements.

I recently discovered these aluminum cookpots with stubby rods welded to the bottom to act as fins. These should improve heat transfer to the cookpot.

From Alexis Belonio:
Good morning!!

Attached are the info on the latest development on rice husk gas stove in India. Just to update you that rice husk gas stove is now being commercialized by Navdurga Metal Industries of India.

From the India Economic Times:

The three-year-old startup based at Faizabad in Uttar Pradesh has created rice husk-powered, smokeless biomass cooking stoves that significantly reduce the cost of household spending on conventional fuel sources such as LPG, electricity, kerosene, wood and wood charcoal. "Rice husks can give about 3,000 kilo calorie of energy, compared with wood that gives between 3,800 and 4,000. These stoves reduce carbon emissions, and cooking costs significantly," said Jaiswal, 31. Nav Durga's first product, aptly named Janta Chulha Smokeless Stove, was launched in 2009 and priced at Rs 500. It has now launched a range under the brand name, Agni, which caters to both domestic and industrial customers. "We currently manufacture up to domestic 10,000 cook stoves and about 50 commercial stoves a month. We want to ramp that up to 20,000 domestic and up to 1,000 commercial stoves soon," Jaiswal said.

According to recent industry data, about 67% of Indian households, adding up to about 166 million households, continue to use solid fuels as their primary source of cooking fuel. While conversion to modern fuels has accelerated in urban areas, rural areas have been slow. Saurabh and the firm's co-founder Arvind Jaiswal, 56, have set up their own distribution and supply chain system. The startup currently has about 50 distributors spread across Uttar Pradesh, Bihar, Assam and Punjab. The company employs about 50, spread across two facilities in Faizabad and Faridabad, in Haryana. "The manufacturing is done by local talent alone," Jaiswal said.

The original news article, and instructions sheets for the stoves are attached as pdf files.

ove Camp 2013 ----- July 22-26,2013 ----- Cottage Grove, Oregon

“Great Stoves” to meet the Global Alliance standards for clean, efficient, and safe cooking.”
Co-hosted by InStove, Aprovecho Research Center, and Paul “Dr. TLUD” Anderson
The Global Alliance for Clean Cookstoves is establishing standards, and this summer’s stove camp is going to focus on the design and delivery of stoves that meet them. We will be looking at the various proposed tiers of stove performance and see which stoves fall into what classifications. We’ll also be exploring design considerations for producers who are interested in building top-tier stoves.

Schedules will be available in early June.
