I'll be writing, here, about TRILOBOATS, 'square boats' and our life on the water in SE Alaska. It's a blend of engineless, junk rig sailing, shoestring living and voluntary simplicity, with a few yarns thrown in for good measure.
In the third world, much of the cooking is done around open, wood fires. We shantyboaters, living as we do in a third world of our own, can benefit from recent innovations in stove technology. Their workings are high tech, but their construction is low tech (or appropriate, if you prefer).
One of the odd facts about wood fires is that, without efficient combustion, up to half the energy of wood goes up in smoke. This means twice as much wood need be gathered for a given amount of heat, leading to deforestation in many areas. Smoke is, of itself, toxic, and women and children (predominantly the ones doing the cooking), suffer heavily from emphysema and other lung conditions and cancers.
The Approvecho Center, with Dr. Larry Winiarski, developed the Rocket Stove to address these problems.
It is essentially an insulated, L-shaped combustion chamber. The horizontal portion accepts wood and air, the hard turns at the angled join provide efficient mixing, and the upright portion is the chimney. The combined effect is a very hot burn, both of the wood and the smoke. Remaining hot gasses emerge from the upright chimney under appreciable pressure.
There are many ways to adapt this concept, including cookstoves, thermal mass heaters, steam generators and so on. For inside use, they may be enclosed in a box and vented outboard.
Holey Roket Stove with Holey Bio-briquettes
One of the more intriguing variations is the Holey Roket Stove. Instead of wood fuel, this uses donut shaped bio-briquettes. These are DIY from slurried biomass (manure, paper, sawdust, peat, weeds, etc.), formed and baked right on the stove. In areas where wood is scarce or protected, bio-briquettes offer a wide range of options for scroungers.
Of course, they needn't be mutually exclusive... with good design, a Holey Roket could burn either wood or Holey briquettes.
StoveTec is offering ready made (outdoor) rocket stoves in a roughly 5-gallon pail format for quite reasonable prices. These would make great deck or 'patio' cookers. You may also purchase stoves for Third World families at very low cost.
So look this stuff over. See how it can be worked in to your situation. The technology is highly scalable and versatile. Chances are, some variation will enhance your life.
