Mike, I have spoken to the UK agent(?) for Ormat It seems that they are only about 10% efficient (hot water in to electricity out) which is a bit disappointing from a CHP point of view but apparently very reliable for unattended operation.- unlike our woodchip gasifiers!! I am following up some potential applications for the Ormat and will share any further technical info.

I'm assuming you mean 280C. Ormat in Sparks NV has a binary system to use low quality heat (www.ormat.com). They won't tell you anything technical as I sure it's all proprietary. However, it is worthwhile to understand what other have been able to do commercially.
