We have had other interest from waste recycling companies to adapt our technology to capture redundant waste heat and generate electricity, we are working on a large standalone unit which will produce over 300 Kw.

Abstract
Wastewater treatment plant (WWTP) utilization of combined heat and power (CHP) systems allows for the efficient use of on-site biogas production, as well as increased annual savings in utility costs. In this paper, a review of biogas energy recovery options, CHP prime mover technologies, and the costs associated with biogas cleaning give a broad summary of the current state of CHP technology in WWTPs. Even though there are six different prime mover technologies, the main ones currently being implemented in WWTPs are micro turbines, fuel cells and reciprocating engines. Different prime movers offer varying efficiencies, installation costs, and biogas impurity (H2S, siloxanes, HCl) tolerances. To evaluate the long-term savings capabilities, a techno-economic assessment of a CHP installation at a case study WWTP shows the payback, annual savings, and initial costs associated with the installation of a CHP system. In this case, a study a payback of 5.7 years and a net present value of USD 709,000 can be achieved when the WWTP generates over 2,000,000 m3 of biogas per year and utilizes over 36,000 GJ of natural gas per year.

Lots of mention of Stirling engines - I wonder how our proposed 300kW model stacks up, e.g. in contaminant tolerances "Table 2. CHP prime mover tolerance to biogas contaminants." and NPV "Table 4. WWTP utility and operating characteristics used for the case study analysis.". Should be significantly less than their assumption of $2,500 per kWe capital cost.
Of course we have no idea what "will produce over 300 Kw." actually means. Heat? Electricity? Both? Sigh...
