Diesel anyone?

This is pretty interesting.

160lbs, 100hp, burns jet fuel, supercharged, 2000 hour TBO.

Fascinating theory.

Sounds pretty exciting, other then the $25K price.... :-)

A very interesting and unique design. Thanks for the link $25k price would put it right with Rotax, the most popular engine for Light Sport (other than Sonex). Could be invaluable if as expected government messes up lead free av-gas so much as to make it un-available and/or un-affordable. Our engines will run on good Mo-gas but quality varies so much as to make it unreliable when traveling away from home airports.

My initial take on this is its promising for slow type airframes that are currently using Rotax's.
I'm a skeptic when it comes to a Sonex airframe. For the same reason the Rotax is a marginal install.
Gearing. This is using reduction instead of direct drive and turns to slow for our style of airframe with its broad speed range.
I don't see a Sonex using a 70" prop very successfully. I'd guess that's going to be about in the range of diameter this engine is going to be pared with. Maybe even a touch longer.
If I was building something along the lines of Highlander, I'd be looking hard at something like this.

Interesting take.
Wouldn't you just be able to increase the pitch of the prop to deal with a lower RPM with the same diameter?
