This is not at all far fetched.  Several people are bulding teir own turbines and other things like pulsejet engines etc.  However you can get surplus APU's (auxiliary power units) at bargain prices if you look around.  Check here:   http://freespace.virgin.net/dyno.power/gasturbine/

Fun stuff!  Pulse jets are not just for the military anymore! There is even a guy talking about building his own personal cruise missile. =-O           Talk about civil disobedience!

Apparently, it's not as far fetched as one might think. I'm still unsure of thermal efficiency and if it's competitive with other cycles. In theory, it should be.
 
Has anyone done similar research?

Don and John have both built fine shaft engines so there is no reason
why you can't build yourself an auxilliary generator. You should be
abe to use a very small gas generator perhaps couple to the turbine
of a slightly larger turbo. replace the compressor with a step down
gearing and into a generator.... see what John has built here...
