Philip, Here in Vietnam bottled gas costs more than $21.00 US per bottle. There is no distribution problem here at all. Some households use up a bottle in less than one month. When the monthly wage is not more than $120 US per month, the situation is extremely dire.
In many parts of Vietnam, rice hulls and coffee husks are often dumped in rivers and valleys. Sometimes they are uselessly burned as a means of disposal. With the right type of stove, these agricultural residues put out a beautiful blue flame that rivals that of bottled gas. When we derive energy from fossil fuels, there is nothing of value left behind. But when we gasify or pyrolyze biomass, a valuable biochar remains. When incorporated into the soil, biochar promotes plant growth and sequesters carbon. Why derive energy from fossil fuels when we can get it from renewable biomass? Are you not, in any way, concerned about global warming? Thanks.
