During the development of the geothermal-solar system, Mr. Rappaport engineered a biomass power project and developed the business plan as well. From this work the development of Biomass One, L.P. emerged and the construction of a 22 MW plant in Medford, Oregon, that has been in commercial operation for the past 30+ years.
