Ooorja First Energy

“Oorja” today represents a new way of cooking and has the potential to grow into a large,
successful business in India and globally. The initiative aims at creating a commercially
sustainable business, offering clean, safe and affordable energy solutions to identified
customers in both urban and rural households in developing countries."

Teaching Renewable Energies and Sustainability in the School of Diogo Vaz (São Tomé, Africa)

This work aims to show how sustainability and renewable energies could benefit a rural area of Africa (in São Tomé) by means of using solar energy and biogas. Applying these technologies requires ingeniousness and little founding, the favourable outcomes are becoming less dependent of fossil fuels (wood, coal and gasoline) while saving time and, more importantly, the forest. We have taught how to design, build and operate systems for cooking, lighting and water-heating that use renewable sources of energy.

Magh CM Woodgas Good Stove http://e-maghcm.blogspot.com/ designed recently is a very low cost TLUD stove meant for Common Man (CM). This can be produced by the local communities with less than 8 dollars (USD). Under Magh CM series I have designed many stoves / burners in the past. This stove design is one of the most acceptable stoves, as it has the options to run on forced air / natural draft. Most importantly the convenient charcoal / ash removal facility is created at the bottom, the grate can be simply lifted using a wire and immediately refilled for reuse. The additional window for secondary air in case of no power, the primary air control and the 12 V DC powered fan makes it like a geared vehicle for multiple options to control the heat / flame / updraft. Used the most commonly available oil tin can of 12 inches x 9 inches x 9 inches with a combustion chamber of 6 inches diameter and 9 inches height for the convenience of adoption for a family of 5 members cooking needs. The tin cans are easily available all over India. Posting here the pictures and the design for your valuable comments for improvement. I am thankful to all for your valuable suggestions in the past. This is the 30th Good Stove design of Avan and Magh series since last 4 years of my research and design. Happy to share that the people who have seen this stove have paid money in advance for having these Stoves.

Paul Anderson, 2009 SeaChar Stoves Workshop

The efforts at SeaChar (Seattle Biochar Initiative) produced a 5-gallon (22-liter) TLUD.

"On Saturday, August 1, Seachar hosted Dr. Paul Anderson (Dr. TLUD) for an all-day workshop in the construction of Top-Lit Up Draft (TLUD) cookstoves. The stoves can quickly be constructed from commonly available materials, and produce charcoal while providing heat for cooking (or other uses). Paul’s TLUD stoves have been tested and shown to produce very low emissions of CO and particulates. The stoves can provide benefits wherever people rely on biomass for cooking. TLUD stoves use a wide variety of small pieces of biomass for fuel. The clean burn greatly improves indoor air quality compared with open burning and many other types of stoves. In addition, the charcoal can be used as biochar to improve soil fertility, sequester carbon, and potentially provide a source of income through carbon credits."

For More See: http://seachar.org/wordpress/?p=176

The focus was for making biochar, but this size of TLUD will be highly appropriate of institutional-size cookstoves in the developing countries.
