Dan, There is a company that builds a rotary engine stationary generator. They are located in Texas around the San Antonio area. Sorry, but I don't have an address as my hard drive crashed last week and I lost all that valuable information. As I recall, the TBO on them is in the thousands of hours, only being shut down for oil changes. I once had a chart that shows bearing loads. Its lowest at 5900 rpms. Mark Steitle
