Another interesting invention i discovered listening to Treehugger podcasts. It's a small wood stove about the size of a gallon paint can. It operates by gasifying wood in a lower section and burns the gas in a hot upper section. Cuts down on smoke, need for charcoal, forest requirements.
It requires a fan which requires energy. There is a small battery pack using 2 AA batteries which are said to last about 10 hours. Cost is just under 200 bucks (sample of one testamonial) which seems a bit rich for third world countries. I'm sure Walmart could bring that down to about $30-$40, no?
It looks to be marketed now as a camping stove (car camping) but enthusiasts claim this will be good for Africa and other developing areas. Theoretically, any kind of wood could be used but in practice, it seems to favor the use of dense, pourable pellets.
So is this a good solution to deforestation? Or just another 'disposable' consumer product that will find its way to the scrap heap in a few years. Or is it just a marketing ploy for pellet manufacturers?
5 Stars for ingenuity.
