Moreover the use of solid fuels is strongly rooted in the daily cooking habits: charcoal before and wood currently are more practice and energy-dense than rice husk. However, access to firewood is becoming expensive, unreliable or difficult, thus the provision of the population with a wider energy technology portfolio may protect them from price shocks or fuel shortage. The eventual possibility to use other fuels (such as other biomass residues or firewood itself) in an efficient way with the stove model proposed is a feature that is under investigation.
