Someone has coverted the Mazda rotory engine for aircraft use, Google it

The only problem with that is we don't fit into the military's same financial realm. If you or I produced that same engine, would we sell it to us little LSA people for $5000 (our budget) or to the military for $5 zillion with their budget?  We as little LSA and Experimental type people cannot compete with the military demand dollar for dollar for the same product.  Also we need a tiny fanjet or turbo prop because we only need to go 100 mph and less than 250. The efficient turbine to turn that will be very small especially if we utilize all the heat.  

 

Google "nano turbine" technology.

 

We need the kid or thinker who can think backwards. One that begins with the light single place aircraft, with a nominal speed of about 60 to 100 that requires x amount of energy converted to x amount of power/trust and then design that power unit for that need, what ever technology that would be. That same power unit would then supply many needs, auto, aviation, motorcycles, generators ATV's etc. The 50 to 100 hp is probably the most common and needed range of power conversion there is. It will propel 1 to 2 people where ever and however they want to go. Kind of like "one horse power" The only problem with the horse is he only had one speed. He was very efficient though. He could eat unfossilized vegetation and convert it directly into motion, something that NASA scientists have yet to do or even conceive. And the horse was even personable. You could even love him!

 

Funny how we can get 300 to 600 people from here to there but we have trouble getting 1 to 2 people there.

 

We should have a few great minds thinking about that.

Aren't cruise missiles powered by small turbine engines? Perhaps one of those would be a good fit for a small aircraft?

Not that many years back. Allison Aircraft Engines, now Rolls Royce, built a small turbine that produced about 150 HP and weighed in at around 70 Lbs. It was installed in some "experimental" vehicles and they were driven by company personel. That same engine is stil in production and is used by the military.
