Ballard (a fuel cell leader) is making some stationairy power systems, but they are designed for fairly larger installations. They are also expensive. I also have no idea of where you would think a fuel-cell based plant could used somewhere a traditional diesel/natural gas/propane generator could not. A common technique in large office buildings is to purchase two parking spaces in the parking garage near the outside wall. Build a room around the parking spaces, install the generator, fuel storage, ducting for the air intake and cooling, and exhaust pipes. Cooling air is exhausted back into the parking garage. One of our locations has a nice 125kW generator installed in a such a configuration. Tom To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
