The Greenway Smart Stove is an insulated metal stove, that appears to be a rocket style design with bakalite handles and a metal pot rest and fuel rest. You can see more details in the Greenway Smart Stove flyer.

This stove is marketed as an improvement over the mud Chulha, which is familiar in India.

UNEP and the GACC is working with (COAM) the Conservation Organization of the Afghan mountains.

There are a couple of additional pictures of their stoves here:

The pictures show how I use a wax-card-board milk-box as fire-starter.
The idea could be stimulating to use other types of wax-boxes in a similar

- 8 in-cuts into the edges of the milk-box,
- Push-in the in-cuts
- Fill-in with some small wood-spoons (They look heavier in picture, because close to the camera)
- Light on two in-cuts and let burn for a while.
- When the "bridge" between the in-cuts burns, turn that part down and
- Put in that position into the stove upon the logs
- Add some small wood upon the burning milk-box.

So I start my commercial stove (Rink-Kachelthermo) and use it in Top-lit updraft mode.
After the woodgas is burnt, the primary and secondary air-slits are closed.
By the rest of air comming into the stove, where-ever, all charcoal is burnt slowly during hours. Naturally the stove has to be inside really hot, to work like that.

the wood-sticks are split from logs down to about pencil-diameter or little bigger. I let dry my normal (beech-)logs for at least one year. Naturally the small sticks split easier when fresh, but with a good hatchet that is no problem, they only "jump" more aside.
But if a fresh log is cut in pencil-like sticks, one can cut it directly and the pencils are very fast dry. Simplest method to see and use them if they are dry: weigh a handful of fresh cut sticks by a kitchen-scale let the sticks dry in house and test the weight-difference. I suppose they will dry within a short week or less. They loose about half the fresh-weight. -I do that as well with bigger logs to see how they loss weight under roof on the balcony, an mark the weight on the log with date.

I only put the sticks into the prepared box to light the sticks quicker. If you can put them above the laying wax-cardboard-box (without rolling aside, what sticks like to do :-) ) it is not necessary to introduce them into the box.
Certainly you have some other form of wax-cart-board-boxes. Then you must change the in-cut-geometry.
I have not every day a milk-box from one liter, so I am tinkering to pre-warm the kindle-sticks outside the stove before the stove. -If the sticks are pretty pre-warmed, e.g. in a not yet cold oven-box of the stove (few less than 100°C!) one can light them amazingly quick. I think, it can be achieved to light them with a match.

I want to share with you some data abaut solar cookers in europe!

**What is a solar cooker?**

It is not so complicated, a solar cooker, or solar oven is a box which uses the energy of sunlight to cook meal or sterilize.

Biocharproject.org announces the stumpy biochar combination cooker.

Its a tlud its a rocket stove it has many applications and fully customisable.
Simple design utilises waste LPG tanks to provide safe efficent cheap cooking.

Designed and Made in Australia by Biochar Project and Labrador Mens shed.

The system uses

  1. Biochar reactor to convert all residues and purpose grown crops (especially bamboo and acacia) to biochar for use as a growing media, filter and for feeding to fish with wood vinegar (1% biochar with ,25% wood vinegar).
  2. Heat from biochar reactor maintains optimum temperature for fish and pl,ants
  3. Biochar used as a medium for improve nutrient uptake in either pots tanks or troughs. Note with biochar water flows through troughs for only 1-3 hours per day reducing electricity requirements.
  4. Aeration pond to grow water plants, fingerlings and filter water

An Efficient Cookstove with two burners, two heating surfaces and a small oven:

This stove is designed to work with Vetiver Grass, they also have plans to encourage small scale productions of Vetiver grass straw pellets for use by the wider Haitian community.
