Equipment and products that enable us to use renewable energy instead of fossil fuels and conventional electricity are highly beneficial. Examples include solar thermal systems, solar electric (photovoltaic) systems, and wind turbines. Other power generation equipment, such as fuel cells and some energy storage systems (like batteries) are included here because they help us accommodate varied energy sources so that we may eventually move beyond fossil-fuel dependence.

    BioMacht
    Biomacht provides medium-size (50 kW–2MW) generators fueled by waste heat from biogas, diesel, or other types of engines often used for combined heat and power at the district scale. Importing technology developed by Biomacht’s European partner, GMK, the modular systems offer a plug-and-play design. By using a proprietary organic compound as a heat-exchange medium (in a process known as the organic Rankine cycle, or ORC) rather than generating steam to turn turbines, the Biomacht systems can make use of relatively low-temperature energy that would normally be ejected. The system can also provide combined heat and power from geothermal sources or from industrial or even electrical waste heat (e.g., from a data center). ORC systems have been in use throughout Europe for many years in combination with biomass systems. Biomacht has brought GMK’s technology to North America and is distributing in Canada and the U.S.

    SMA America offers several Sunny Boy inverters designed for residential-scale photovoltaic applications. The company offers 700-, 4,000-, and 8,000-watt inverters with low frequency transformers, as well as a 3,000-watt inverter with a high frequency transformer. Transformerless designs accompany 5,000- and 11,000-watt inverters. A module-level, 240-watt micro inverter, applicable in shaded situations, eliminates the need for a trunk cable. These German-made inverters carry a 10-year warranty. SMA America also offers PV control and monitoring equipment.

    Blaze King’s Chinook CBT (Clean Burn Technology) wood stove uses catalytic technology to reduce emissions to 1.0 g/hr. The Chinook has a heat output of 40,000 Btu and uses an automatic thermostat to constantly adjust the draft for optimum performance. The Chinook uses two fans to improve heat circulation throughout the room but with those fans consuming 60 watts each while running, there is an energy penalty to using them. These stoves are available with straight or curved sides.

    Quadra-Fire’s 3100 and 4300 Millenium ACC non-catalytic wood stoves use four-stage combustion while having particulate emissions of only 1.1 g/hr. The 3100 is for areas up to 2,600 ft2 and has a heating output of 51,100 Btu, and the 4300 has a heating output of 56,000 and is for areas up to 3,000 ft2. The company’s Four-Point Burn System consists of a primary burn zone at bed of coals, a secondary burn zone, a tertiary burn over the baffles, and the final burn zone above the baffle, which helps eliminate fine particulates. Both stoves come with Automatic Combustion Control (ACC), a heat-management system that controls the airflow for an efficient start and consistent burn cycle.
