OK we've had a few discussions on alternative fuels now, so its time
for a round-up. LPG with diesel 33/66% gives more power and less
particulate emissions and is rebatable at tax time(in Aus). Weight
restrictive on A/C. A good power increase for lower powered diesels
without up sizing cubes and I'm looking at it for my purposes. But
what Hasn't been clarified is the effect of H2O on the combustion
reaction, we've had to and fro's blah blah but if  it will allow
increases in range by allowing LOP due to better combustion in
rotaries why should we not investigate it as another advantage of the
no valve arrangement. Paul has been obvious in his opposition to H2Oas
a pure fuel supply, but what as a supplement. Weight and range benefit
balanced. If I was to Fly from here to Perth, 2500+ Kms could I do it
with 1 or 2 stops. BTW at our local fuel station we can now buy 100
octane unleaded 10% ethanol, it is supplied for the speedway nearby.

  I was watching some nascar and at the bottom of the screen they were
proclaiming ethanol as the first anti-nock/detonation,      NOW IT'S
BACK. could those more enlightened "please explain". Oh could you also
elaborate on the weight/volume/calorific/octane theory for complete
clarity please. a/f is measured weight for weight not volume of
fuel/weight (of air). I'm sure someone Knows the answer, if not we can
work it out by debate. I do have Chemistry knowledge and need the
scientific figures.
yours hopefully

In addition to half the range and all the other H2O drawbacks it is half the power.
That is a direct result of it gaseous form. It is hard the get enough H2O gas in the
combustion chamber to generate the power the rotary is capable of on ordinary
gasoline. It is a fundamentally impossible.

Now if you wish to use liquid hydrogen don't expect me to be within half a mile :)

To even discuss alternatives to gasoline is to distract attention from the real
issue. There is plenty of gasoline in the world and there is no real problem burning
it. It is only necessary to drill for it. The gasoline and CO2 controversy was
manufactured by Democrat liars seeking absolute political power.

Paul, I missed getting some of the discussion points that preceded this commentary.
I am of the same opinion as you in that gasoline is available in large quantities and
distributed worldwide in convenient form.  It also packs lots of energy and works
well in the internal combustion engine (ICE).  Nonetheless, I enjoy hearing the
arguments made for alternative fuel concepts, none of which are new and none of which
have become viable.
