I spent quite a while chatting with this guy, Micael Murray at OSH. He was
also exhibiting a turbine but was also talking realistic numbers. He had a
"firewall aft" display suitable for a Long-EZ or other pusher on display that
is slated to go into a factory Velocity. WOT flights in a Long-EZ would be
very short, something like 24-30 GPH.

What is more interesting is his other research into "propfans" like the 8
blade unit he is currently working on.
An intrigueing quote "It was designed specifically for use on the little
T-62T-32 turboshaft engine, but could be used with any engine capable of
turning it at 6000 rpm, and possessing a small frontal area; perhaps a small
rotary."

Small turbofans have the same scale boundary problems Monty mentioned. I doubt seriously
that Williams will get the .5 pound of fuel per pound of thrust they
claim for their small turbofan engine. They refuse to give me test numbers
even though I have asked for them for the past three years at OSH. The engineers 
recognize me coming and and exclaim: Oh no! Not Paul Lamar! He is going to ask 
us what the actual fuel burn is again. Frankly they have scammed us for  100 million
of our tax money.
