Steve Spevak, Clean Burn Solutions, is an “Inventors’ Inventor”, according to artist Gary Castell. During childhood, his curiosity was not always appreciated as he took things apart to discover how they worked. But as he matured he excelled in architectural and mechanical model making as well as drafting, which later enabled him to draft his patent drawings. Steve’s other mechanical inventions include a tool container, internationally patented by Potomac Applied Mechanics Inc. This developed into the pursuit of computer scrap gold and silver smelting and refining. In 2002 Steve authored the Kindle book Backyard Gold Refining Photo Journal, which led to the formation of the Gold Refining, with currently over 30,000 members. In the renewable energy arena, Steve and a team from Monegon Ltd. received Special Construction/ Solar category awards in 1983 from the Washington Building Congress. Later his fervor shifted to renewable heating, with combustion experiments and smelting, along with the clean production of wood charcoal. Now Steve has developed off-grid, biomass gasification stoves, including the VibraStove™, as well as some model boilers/ furnaces. They burn very efficiently, with low emissions and low stack temperatures.


We are the Stony Brook Wood Stove Design team. Our group consists of undergraduate Chemical Engineering students brought together by a desire to study combustion and make an impact in the field. We began this project in January of 2015 with an application for a grant through NYSERDA under the Renewable Heat NY initiative (award No 63043). We began our research in earnest September 2015 with two goals. First, to take a dated wood stove and make it as efficient as possible and second, to use the experience we gained to create "A Next Generation Woodstove". At this point in time we are in the development and testing phase and we would like to share some of our results.

The University at Buffalo design team has purchased and set-up a commercially available pellet stove as part of a NYSERDA funded project for the Alliance for Green Heat Pellet Stove Design Challenge. A Quadra Fire Classic Bay 1200 pellet stove was selected based on references from trusted sources. The first year of the project required the team to create an experimental setup to define the baseline emission level and combustion efficiency of the pellet stove without using any available specifications provided by the manufacturer. Therefore, by using a combination of undergraduate knowledge and engineering judgment in conjunction with the equipment selected, the team is confident in the accuracy of the experimental setup.
