Hey Tom, I think small generation is feasible, but not with Cyclone/Q2Power equipment.

Here's an example. Yanmar (the Japanese diesel engine manufacturer) makes small units that run on bio-methane. Specs for the 25 kW unit are at http://www.yanmarenergysystems.eu/Products/Micro-Cogeneration/CP25WE-BIOGAS-34/

Notice that the maintenance interval is 6,000 hours. If you don't run it all night (when electricity prices are low) you only have to change the oil and filters once a year. Yanmar offers extended warranties on this model for up to 60,000 hours or 10 years.

Yanmar doesn't seem to let dealers advertise price, but a 25 kW Kubota diesel genset in a soundproof outdoor enclosure goes for less than $20K. Let's suppose the Yanmar converted to run on biogas goes for twice that. That would be a 25kW system with controls and an outdoor enclosure with two year unlimited hour warranty for $40K, the price Harry Schoell had speculated on for his bare 10kW WHE generator.

Also note the conversion efficiency to electricity is 33%. Q2Power will be lucky to make 6% with their low temperature and pressure, long cutoff steam engine with little or no expansion of the steam.

That means a sewage plant would get 5x the amount of electricity from their methane by going to the Yanmar rather than the Q2Power system. So 5x the revenue from a lower cost and more reliable system.

But we are still talking a small town sewage plant or a good sized cattle farm to fuel one. Harry's original boasts about homeowners burning their garbage in a Cyclone WHE generator to power their homes wasn't anywhere near reality even if the engines did work.
