-=0ASince we're on this topic of engines, when are they going to develop

sounds too good to be true, the Zoche aero diesel, the wonder engine which
is compact in size, lighter in weight that most gas engines, and will prob

natural 300HP http://www.zoche.de/zoche_brochure.pdf=C2-,which the compan

The problem is, a light weight diesel is by no means lighter than a light
weight gas engine. A diesel is heavier by design : more pressure in the
combustion chambers, more torque variations, etc.

Got to be something like that, someone is paying him to keep it off the mar
ket.- I would think he'd make much more money though if he'd just release
the thing to the general public as it would be in huge demand.- He's eve
n got-the prototype in a video that is-so quiet it was amazing.-Most
of the noise came from the propeller blades.- Patent the silly thing and
get it on the market, because there's nothing remotely close to that diesel
now. It makes the-Thielert Centurian- and DeltaHawks engines looks lik

I've been watching this thing for 15 years. If something sounds too
good to be true it probably is!! I did hear that he is getting some
kind of government financing while in development. So why finish
development? Also, maybe the thing really can't do what he is promising
so he just keeps on promising and living off his government.
Much of the above is hearsay, but I certainly would say, 'Don't hold
your breath for this engine!'
