This technology is realized integrating in a single system 1 a Stirling engine mRT-1K from a pre-engineering design of Allan J. Organ 2 a micro-heat exchanger technology to reduce the net transfer unit deficit on the hot side of the heat engine 3 a customized pellet boiler able to extract electrical and thermal power and 4 a customized hydraulic circuit connecting the cool side of the Stirling engine and the heat generation on the second section of the pellet boiler. The objective of this paper was to present a new technology for the micro-cogeneration of energy at a distributed level able to be integrated in domestic dwellings. Most part of the available biomass is used in buildings for the generation of thermal power for indoor heating and in minor cases for hot sanitary water. In the Province of Trento 88 of the biomass is used for this purpose. The full system is actually under integration for the test phase and not yet tested. The first tests on the single components have confirmed preliminary results on the Stirling engine with respect to the tolerances pressurization and proper integration of the electrical generator-driven control system. The pellet boiler has been tested separately confirming an overall thermal efficiency of 90 .
