They had to drill a pretty deep hole to get a clean power flow for the Geo, and then the scrubbers, filters etc. to use it within emission guidelines. It's way more complicated than I would have thought, Gov regualtions being a major hurdle.
I was in the Engergy Consultant business for about 20 years and have worked internationally on some cutting edge stuff, some of it works, some of it doesn't. It's over the long term (years) that you begin to see the problems, which aren't readily apparent when you first start off.
I've worked on Deisel power generating systems as well (Marshall Islands group, Gaum, Hawaii) and there 'complex' in the long run as well, though commonly used. Sulphur in the fuel remains a problem, again, it clogs and eats things up in time.
I kind of wish I was involved in this new 'wave power' approach it looks real good. But consulting was another life in a galaxie far away, I mostly just drive my Cobra these days.
