What's there to disagree with ?
At 10 gph more that's 180 lbs more in take off
weight for a 3 hour flight.
A piston engine consumes about 0.5
lbs/hp/hr
That turbine is just over 0.8
lbs/hp/hr
For 200 HP output, that difference is 10
gph
. . . so 125lb turbine + extra fuel or 305lbs for a
piston and less fuel cost . . . for the life of the engine.
. . . take your pick.

I have to disagree with
Wolfgang on this one, but I do accept his premise that a 240 HP turbine will
consume a lot more fuel than a 240 HP recip.
But the amazing thing is getting 241 HP out of a 125 pound engine.
*That* is impressive!
Put it in context - my IO-360 gets 180 HP and weighs 260 pounds.
Marv's engine provides 33% more horsepower and weighs less than half. We
can run every comparison under the sun and argue all day long to no conclusion
-- how much extra fuel weight we need to carry, how much less engine weight we
need, and so forth -- but the bottom line is that this little engine enables
some aircraft designs that just would not be possible with a recip.
