  • Case study - Smith Gardens, Inc., Bellingham, Washington, USA

    “In 1993, Sid Abma installed a new 350 HP boiler along with his SRU stack recovery condenser, to heat a section of our greenhouses in Bellingham, Washington. While the boiler requires yearly service and maintenance, the condenser requires no maintenance. It just sits on the floor next to the boiler and gives us free heat. Sid was able to pipe the condenser in a way that takes maximum ...

  • Sheep–for–meat farming systems in French semi–upland area. Adapting to new context: increased concentrates and energy prices, and new agricultural policy

    We used simulation to study how three French sheep production systems could adapt to a new context created by a surge in cereal prices associated with changes in common agricultural policy support. The evaluation criteria were economic performance, energy efficiency, emissions of greenhouse gases, and sensitivity to technical and economic fluctuations. We found the most intensive system was the ...

  • Tetra–stable bifurcation structure of the climate system of Earth: mechanisms triggering potential transition to the greenhouse steady state

    The emissions of human–made greenhouse gases may trigger transition from the pre–industrial climate to the greenhouse steady state, which was for the last time abandoned 49 million years ago. The study provides an energy balance climate model with temperature–dependent parameters, which illustrates the tetra–stable bifurcation structure of the climate system. Bifurcation structures can evolve in ...
