But why send it to the US for processing?

The Americans have several bio kerosene blends availible based on canola and other oil seed sources.

One processor is the Syntroleum corperation, there are others too. The former made batches for the US Air force.

Various blends have been made  for testing by various airline and engine manufactures. The reason it is not done here is due to the fact that in the UK we are risk averse and do not invest money in anything useful.

Biofuel for the airforce is hard to comprehend. I remember someone asking me once for a wind turbine which could run in 300mph winds. I asked if he was installing it on Saturn. Turned out that he ran an RAF jet engine testing facility. They run jet engines for several hours each day, and wanted to recoup some energy from the exhaust. He didn't seem to understand when I suggested running the facility for 15minutes less each day - which would result in a far greater saving.

To defend the Chap you mention there will have been a set number of evaluation hours to run on the jet engine so he wouldn't have had any choice.

The power recovery system for a gas turbine is called a Free Power turbine as it is not mechanically connected to the main turbine shaft. AFAIK they are not fitted to aircraft engine turbines, only land and marine power generators.
Unfortunately that would be designed and built to match the overall unit, although I expect a good design could act as a generic bolt-on power recovery unit for a variety of turbines, so long as it didn't affect the turbine outlet pressure.

Did you not recommend him a Proven?
