It is being built. They already had the test plant in philadelphia running and producing oil. They are building a large scale plant in missouri in a cooperative agreement with Butterball turkey(conagra?) who will provide the turkey guts they will use to power the thing. If they get it working good, you WILL see them going everywhere.
here's an update on the the plant.

I've been following this one for quite a few years. If you follow any science periodicals you've heard of it for quite some time. Would have invested myself in the large scale plant as they were in the planning stage of it when I first heard of it but couldn't find any way for the average joe to get in on it. this one ain't b.s. I give you my huntchat secret handshake .Take care.
