Rocket Stove Principles are profound and powerful.

We demonstrate how rocket stoves are able to bring humanity into an age of personal energy independence and truly sustainable living.

Working with Dr. Larry Winiarski, the inventor of the rocket stove and author of the Ten Principles of Combustion, we have designed, built and implemented the rugged forge-like SR100 Rocket Stove Combustion Chamber –Thermal Battery — Radiant Heat System which provides continuous heat and keeps people warm in their homes, heats greenhouses and work spaces, and provides hot water for kitchen, showers, bath and hot tub.

The Combustion Chamber design follows and evolves from the Rocket Stove “Principles of Combustion”.  This larger size rocket stove uses 90% less wood and the fire  burns as hot as possible to achieve complete combustion and therefore produces the least pollution. 

The tall insulated chimney allows additional combustion and creates a powerful draw of outside air right into the center of the fire and sustains a very hot rate of burning.  Remember the time you blew into a campfire.

An incredible amount of pure heat is captured into water circulating through a copper coil placed right inside the chimney and heats the water in the “Thermal Battery” (a hot water tank). 

This Thermal Battery is the core of the Radiant Heat system.  For Space Heat, hot water is pumped from the thermal battery into hoses that heat from under the floor or alternatively, hot water is pumped into a radiator with a fan blowing air through it.  The radiator and fan combination provides fast and efficient heating.

Running hot water for faucets and showers is on city pressure and is heated by running city water through a long coil within the actual hot water tank and then to the sink or shower or or hot water hose.

The first video is one of the early burns of the pellet hopper automatic feeding system.  Larry’s voice in the background is saying that this stove burns pellets in the same heat range as coal.  The pulsing is called the thermoacoustic effect and can be used in a sterling engine to produce electrical flow or  to create refridgeration.   

The second video shows that we are able to burn wood (biomass) with a blue flame.  A blue flame is quite pure and burns hot.  Our research leads us to develop in-stove methods of refining the chimney gases that will be able to run internal combustion engines and to run electrical generators.  

The third video is taken through an opening between the bricks in the back of the stove and shows the flame as it leaves the combustion chamber and flows down the burn tunnel and up into the chimney.  This is how the stove normally burns and this is the level of heat that is sustained for hour after hour of burning.  This heat then surrounds the sixty feet of copper coil in the chimney and heats the water flowing through the coil and raises the temperature in the thermal battery. 

Complete combustion is when all the carbon bonds are broken and only water and carbon dioxide come from the chimney.
