Hi Stovers,

On a slightly different note, does anyone have access to the CFD simulation work done for the Bio-lite stove.

Cheers

There are very few initiatives that support pro-poor energy policies, compared with the largesse that flows to energy for the rich. The disparity has always been a sore point for appropriate technologists as many of us know.

Several devices for chopping and for grinding cassava were brought to SD-land, to the agric research centre in Malkerns. There was obviously a difference in approach to ‘A-T devices’ for local manufacture. There is no way we could copy them for local use as they would not have lasted long enough to secure the reputation of the vendor.

Those things are still around. India is full of copies of such technologies. My question to you is where are the Guatemalans on this scale?

The comment ‘it can be made without welding’ is odd in that welding is one of the near-universally available skills in fuel-deprived areas that might be interested in biomass briquettes. The reason the fuel is short is because there are so many people and where there are people there is transportation which means vehicle repairs which means welding.
