Tom Range fuel gasification technology was an externally heated pressuries pipe with a transport screew inside when I saw it. It was very similar to the pyrolysis unit on the wiking gasifier but they had ideas to upscale it to 4 tons pr hour by stacking pipes with screew conveyers. Thinking of the challenges of making the 1 tons pr hour screew pyrolyser in Haslev i have doubts this principle will ever be competitive for energy production - even for atmospherich applications.

The appropriate use of public funding is to offset risk on new technologies. The funds are not free. Private companies often prefer to forgo public funding simply because of the time and costs involved in obtaining the funding and managing the project. I think US Department of Energy has not been pleased with the results from their funding of the "Integrated Biorefinery" pilot projects in general but it is a multimillion dollar effort and there will be failures. Range Fuels published very little about their process, even to funding agencies. Early on I understood that it involved slow pyrolysis as a first step. As such it presumably should have been a good process for making synthesis gas and biochar. Perhaps like some other processes another company will pick up the pieces and eventually make renewable fuels.

Over time, its currency will decline and its standard of living will decline. It is much wiser to keep funding research and development and just try to get better at how you do it. JAMES T.
