RE: Landfill Gas Cogen Project in Delta, B.C.I studied the MXG system quite closely. In this instance I think that they are simply supplying the excess heat to the Greenhouse operator. In other combined cycle operations they use the heat to turn steam generators thereby improving the net eletricity recovered from a given amount of gas.
I've been buying more CAE (picked up more today) and have held my AIQ. I am a bit ansy about large holdings in small companies after a few bad investments so I will keep my AIQ position modest.
