Not really -- at these sizes, axial flow engines are incredibly inefficient and complex. A single-stage centrifugal compressor with single-stage axial-flow turbine is a far more practical way to build a small turbine.

Note the blue flames coming out the tailpipe... *not* a good thing. The EGT must be *way* over-temp in those pictures. You don't see blue flames coming out the tailpipe of a jet engine when it's running properly -- there should be no flame at all -- unless you're looking at an active afterburner nozzle and that doesn't have an AB.

I love the way it's intermitantly spitting bursts of flames so one of them sticks his head down their to look up it
I'm never wrong, once I thought I was but I was mistaken.

Thanks for the info so simple is better when size is small

yes the blue flame was only there for a spli second

I did wonder about the guy putting his head apparently in the way ;}

thanks for the responses i will read up on "single-stage centrifugal compressor with single-stage axial-flow turbine"

Still an impressive piece of engineering, look very pretty.
-but for effectiveness if lack a lot, compared to model-jets-engines

Bruce is right, EGT appears way too high. Efficiency is everything in our scaled down world, and them blue flames are telling a whole different story than the man trying to sell it. Mind you, this would make an awesome conversation piece, fire it up in front of your guests, and say "DISCUSS!" while they stare at you in awe.. Okay, I'm a little strange...
