The Peko Pe TLUD project in Zambia is going well.

Paal describes it best:

" The main principals for our projects I will call it community based participation both for fuel and for stove productions. Utilization of local resources with other words.. The Peko Pe is designed for production by local tinsmith with the tools they might have. They only need a template and a model; they have the knowledge how to make it.

" First of all we discuss the need of changes, and then on the fuel side we start up with registration of alternative biomass for fuel for briquetting, energy forestry for fuel production. We always start with the fuel .to be sure there is sufficient quantities and to an affordable price.

"The charcoal business, which represents about 15 % of the adult population, has to be involved from an early stage of the project. All kind of activities on the household energy sector will in one or another way have an influence of their business, and with biochar we don’t know what will happen, but that is one of the ting we will try to find out. Any how for the charcoal business it is just to change from charcoal to alternative biomass for household energy.

"The energy loss by production of biochar for soil improvement is almost equivalent to the energy needed for the farmer to cook if you include the African way of thinking time is coming not like by us time is running That is a big difference. A household need about 2,7 kg charcoal a day for cooking. Form about 10 kg of dry wood you will get 2,7 kg of charcoal for one day cooking and no biochar. From .10 kg of dry wood you will get 10 kg of woodchips and that will be for 2 ½ day of cooking into a TLUD-ND. and about 2.7 kg of biochar. The pilot project will tell us if this is right or wrong."

" A common Miombo forest in Africa will give about 3 ton wood per ha a year. 3 ton of dry wood will give 800 kg of charcoal. A household of 5 consume 2-3 kg charcoal a day or about 800 kg a year. To produce 3 kg of charcoal you need 10-12 kg of dry fire wood in a common kiln. That will give one day cooking on a charcoal stove, and almost no biochar. 10-12kg dry chopped wood will give 3 days of cooking on a TLUD-ND or another FES and 2.5 kg of biochar
Energy forestry using just the sprouting every year can give up to 10 ton wood per ha a year, easy to cut to appropriate fuel for TLUD-ND’s or other types of FES. By adding some biochar to soil of bad quality 20-30 % increased yields can be obtained, which will give more food, more household energy, more jobs, better economy, better health for women and children and saving the forest. It can probably be as simple as this and is that not some of what we are looking for and need?
We know some changes have to take place on the household energy sector and we have to start somewhere. Why not start with small scale farmers on sandy soil, and from there develop the new household bio-energy strategy for developing countries. Probably also with the charcoal business, they have the whole infrastructure intact and can easy change from charcoal to alternative biomass like chopped wood or pellets from agriculture and forestry related waste. "

Biochar Industries part of Biochar Project in Kunghur Australia is now selling Biochar TLUD cook stoves as part of our plan to make more people aware of the benefits of biochar.

T l u d

is an acronym for Top Lit Up Draught meaning you lite it at the top and the air is sucked up through the fire. Fantastic device that is light to carry and will work with all woods great survival tool . The best feature of this Tlud is when the flames go out you then have biochar. All you have to do is drop the embers on the ground and spray some water on them so they don’t continue to burn.

This particular model was imported from India and has a very nice finish and somehow I ended up with some to sell so I wanted to let my readers know first before I start selling them at stores and markets.

My little iCan made from a 3 lbs Costco coffee can boiled 1.75 liters of water in 42 minutes this afternoon. Ambient temp was 47 [8.33C]. This was done in 5 batches averaging 350 ml each. A very clean burn. Some soot at the start of each batch when the water was cold. Just a soon as the water in the cup warmed up a bit, the soot stopped.

Of course I also made some biochar as well.

Fuel was a good quality wood pellet. Cost of fuel: about 17 cents assuming pellets at $230 per ton. They can be bought for a good deal less, but I am using a higher number to be safe.

Cost per liter boiled: ~ 7.4 cents, allowing 4 cents as the value of the biochar captured at the rate of 17.5% of the dry weight of the fuel.

I am looking to get some Anila stove units in India for some small-scale trials - if you can help please get in touch asap with sarah.carter [at] ed.ac.uk

Testing of the Sampanda stove in Cambodia 12.07.2010
Sarah Carter, UK Biochar Research Centre

See http://www.bioenergylists.org/content/testing-andersons-tl for a similar test on Anderson's TLUD, and http://www.bioenergylists.org/content/testing-everythingni for testing of EverythingNice stove, and Anila stove http://www.bioenergylists.org/content/testing-anila-stove.

Stove: Sampanda stove. Produced by the Samuchit Enviro Tech Pvt Ltd in India.
Test: A water boiling test (time to boil 2.5 litres of water, in a pan without a lid)
Location: The Iron Workshop, Siem Reap. A well ventilated building – 2 surrounding walls, and a roof. Wind conditions were low, but blustery at times.
