Biomass gasifier cookstove: manuefacturing and perfomance test and Carbon nanotubes from banana peels

Abstract

Up to now, efforts to replace solid biomass fuels have largely failed as vast numbers of people still use them. The absolute figures are even set to increase in the next decades being that solid biomass is the most abundant source of vital and renewable cooking energy worldwide. The most effective way – as measured by cost, health benefits and adaptation rates – to address the current situation is to re-engineer the devices themselves as well as the practices used in converting solid fuel into useable cooking heat. Gasifiers offer just this opportunity: they are devices that produce their own gas from solid biomass in a controlled manner. Gas generation occurs separately from subsequent gas-combustion, and both stages of combustion can be controlled and optimized separately. Gasification is not a new concept but micro-gasification is a relatively new development; it was long a challenge to create gasifiers small enough to fit under a cooking pot. The volume one of these theses is aimed to portrait our achievement on this regard.
