Freewatt (www.freewatt.com) and Marathon Engines (www.marathonengine.com) are each selling systems that produce electricity and capture heat with generators with natural gas engines.
They each claim to have a very long duty cycle and be cost competitive.
The Freewatt system is Honda engine based, with units in Japan.
The Marathon Engine system is made in Michigan with units sold
in Europe and generator units sold into telecom and railroads.
They seems to be selling them mainly in the northeastern US.
Does anyone have any experience with either?
