Why no new diesel radials?

Just wondering, exactly why are radial diesels not part of the

cowling as the engine was still running (the single Otter had
just landed).

If I won the lottery I'd buy a machine shop. My fist project would be
to machine a radial case to accept cylinders off a deutz engine

There are excavators using those, screaming full tilt all day
long with next to no airflow!

BTW, weren't there some diesel radials in the early days of
aviation? I've seen some photos I think. The high torque
of diesel almost begs for that can't-keep-from-turning
radial geometry.

Anybody know if the Lycoming/Detroit will be air-cooled opposed?

2 lbs/hp, but that was then. I'm sure 1/1 could be
had today (for air cooled).

Yeah I work in an underground mine. I've seen first hand what kind of
abuse these engines can endure in the hands of union personel that
hate the things.

John Ousterhaut told me last week that my idea for a diesel rotary engine
needed more time back at the ol' drawing board. Translation: It won't work.

I didn't tell him I was planning on running discarded Chinese buffet
"grease" through it. g

Heat the grease with exhaust tubing - start and shut down with a small Jet-A
tank. See, I've thought this all through.

Any comparison on energy content diesel v vegetable oil?

On Dutch television they showed a diesel truck that could switch from
regular diesel to chicken fat, garbage from a chicken processing plant. The
truck ran equally well on both types of 'fuel'...

Can you imagine stuffing chicken waste in your diesel-powered plane?

Two thoughts:
1. See, chickens *can* fly!
2. Finally a positive effect of a bird strike..

All you need is something like a Bussard ramscoop, and you can fly forever.....

Some buses in Halifax ran on fishing industry waste oils.
For all I know that could be the whole fleet by now.

What I like about diesel in airplanes is the possibility
of low rpm power for sometimes double the range (at lower
speeds). A radial will turn very smoothly at 1000 rpm
and the diesel would be torquing near optimum just audible
around 1400-1600 (?).
