We, Miombo and the inventor of the TLUD ND Gasifier PekoPe, Paal Wendelbo, are travelling to the PCIA conference in Lima, Peru and would like to communicate with others working on gasfier units and prosessesd fuel out of any type and kind of dry biomass, World wide.

I am not clear about the situation in other countries. But in China, because of the pressure on mitigating climate change and the increasing price of coal resources for heating in Northern China, companies and governments in China are now focusing on renewable rural technologies, e.g. solar technology and improved biomass cook stoves. In terms of stoves, governments and companies are now focusing on designing and producing newly improved semi-gasifier biomass heating stoves for rural households and institutions. However, the technology is still not good enough. Most of stoves in the market still have the tar problem.

This is timely, household energies would be at a no risk truck , if we had this some years back. come this be , we need every bodies effort. Who will mobilize the mass to this life challenging matter?
All needs active participation at all levers, lets start with easy numbers if we a to win this challenge.

Thank you for the comments.
In response to Chongying Chen I think any coal burning combustion stove will produce tar in the same way that wood burning results in poly aromatic hydrocarbons. Depending on the main fuel source of a country, which for China is coal, even improved stoves do not solve all the problems, however by improving combustion efficiencies, and using chimneys and smoke hoods at least the levels of indoor air pollution can be reduced.

The only way to avoid this as you say is to use renewable alternatives. Like using a biogas stove or ethanol stove though these do still release greenhouse gases. There are many stoves on the market which offer improved designs even though there is no one design that is perfect and what is appropriate for different countries is also important to consider here. (See http://www.hedon.info/Stoves+Database) however so far we have not succeeded in introducing viable alternatives in many areas. What can be done to improve this? Do you think solar is a viable alternative for China?

I'm looking for an NGO that might be interested in developing a low cost device to convert stove waste heat into electricity using thermoelectric TECs.
It requires someone able to follow guidance to cut/drill metal as well as having a stove in regular use.
