The creation of the SR100 rocket stove was inspired by the courage of those in the Standing Rock 2016 effort to safeguard the purity of our water. The purpose of the SR100 rocket stove is to provide continuous heat to keep people warm in their homes, to heat greenhouses and workspaces, and provide hot water, in winters that last up to six months with temperatures down to minus 17 degrees. “SR100” refers to a rocket stove engineering specification for the combustion chamber which states: The SR100 Rocket Stove shall be capable of producing 100,000 btu per hour 24 hours a day continuously for six months without failure. The “SR100” specification was written by, and the prototype SR100 rocket stove, seen in this video, was designed and built by John Robert Zielinski under the mentorship of Dr. Larry Winiarski, ten year best friend and inventor of the rocket stove and author of the “Ten Principles of Combustion”. Nick Moses, formerly of the Instove Corporation, rendered the SR100 design in Autocad and CNC cut and formed the stainless steel exoskeleton to hold the firebricks to create a combustion chamber similar to a forge. After the Beloved Festival the pot was replaced by a long chimney with a copper coil inside. Several measured burns confirmed that the SR100 is capable of heating a large tank of water, which stores the heat, and then the water can be pumped to heat a house, a greenhouse, a workshop and a hot tub, thereby demonstrating that the SR100 can function as a central component of a homestead allowing it to be more sustainable and more capable of off-the-grid living. Special thanks to the staff at the Oregon Country Fair Ritz Sauna for guidance in choosing to develop the copper coil technology which is several times more effective than using a pot.

The Rocket Stove Institute is in the process of refining the design and finalizing a real-time demonstration system. We are creating an Indiegogo campaign to be launched mid to late summer 2019 with a second video showing the full potential of the SR100 to fund the development of new features that will include:

  • a hopper that will burn wood pellets or chips continuously for up to four hours or longer with one filling
  • a microprocessor controller run by solar energy which will maintain the proper ratio of air-to-fuel for the cleanest and hottest burn
  • a new technique to manufacture stoves quickly by casting them out of a cellular refractory which would bring the costs way down to around $10 and allow for multiple stoves to heat a tank several times faster.
  • a pioneering new method to create water tanks made on site quickly and inexpensively which are insulated with cellular cement.

This size of a rocket stove has been laboratory tested to emit 90% less pollution and use up to 90% less wood (biomass) than an open fire.
