Feng Systems Inc. (a subset of Footprint Engineering)

Innovative Eco concrete, geothermal HX, and wind turbines.

Feng System Inc. specializes in providing innovative designs for industrial, commercial, and residential applications in the domains of concrete, geothermal heat exchangers, and wind turbine innovation. On the concrete side, Feng Systems Inc. has developed comparatively low-carbon solutions with compressive and tensile strength outcomes exceeding those best commercially available, without using any steel rebar. On the geothermal heat exchanger side, Feng Systems Inc. has innovated a semi-open ground source solution for space heating and cooling, which in sync with a heat pump can provide higher COP (useful energy efficiency) than currently commercially available -- with lower drilling costs. Moreover, the system has no long-term thermal efficiency decreases from thermal reservoir accumulation because it is the first ground source system to also use the air as the source or sink, depending on atmospheric conditions. Feng Systems Inc. also developed the first zenith axis-of-rotation wind turbine, which can be mounted on top of the geothermal heat exchanger to yield power generation on top of the heat-cool functionality. This approach allows net-zero energy extraction and generation, which can also be deployed for off-grid dwellings, as much as supplementary solutions for commercial and residential.
