The video show a Briggs and Stratton running on gasoline alcohol and
 acetylene, I wish it were possible to do this with the rotary to
 test some ideas

 Can you share those ideas Alex? :-)

 Paul Lamar



 I was thinking along the ideas and modifications you Frank and
 others were talking about a few weeks ago, guiding flame fronts,
 additional spark pugs (side by side) more complete combustion of
 hydrocarbons instead of mixture igniting while going out the exhaust,
 changing compression ratios with inserts, additional shapes to induce
 more swirl for complete combustion.

 If you could film it in real time what a great way to test these
 ideas if it were possible to have a clear view on to the rotary
 combustion chamber.

 Attempts have been made to do that in the recent  past (2015) on the
 rotary but due to the geometry and other temperature considerations
 it has not been very successful.

 What has worked recently has been CFD. CFD gives you velocity and
 pressure. CFD is improving all the time. If somebody built my idea of
 a multiple piece  rotor that bypassed squish air it would be very
 very difficult to see that optically. It was CFD results that gave me
 the idea.

 For interest try checking the website for RX7 Specialties or REC in
 Calgary, Alberta. Last I looked he showed some interesting projects
 he has worked on. Built some rotaries to run small compressors for
 the gas industry that burned sour gas to 3% H2S.

I always thought that was a good idea.

Many oil wells burn the gas in the atmosphere when it could be generating
electricity and feeding it back into the grid.

The huge Ingersoll Rand rotary ran on oil well gas.

The advent of the Silicon Nitride 20,000 hour apex seal would make
that more economically viable as the engine could run 24 hours a day for
years.
Lets say it was 200 HP. That is  149 Kilo watts per oil well.

At ten cents a kilowatt that is  15 dollars a day.  About $5000 a year.

in LA  CA  it is about 12 cents a kilo watt.

What does a kilo watt of electricity cost in your home town?.

I pay 29.5 NZ cents/Kw

That is about 21 cents US. If there are any oil wells in NZ burning off
natural gas
a rotary powered generators running on natural gas  would have a big pay
off.
The generator would pay for itself in six months.

Does NZ have any big river  dams with hydro electric power generators?

Hey Paul, if you are ever in New Zealand on the South Island a Tour of the Manapouri Underground
850mw power plant is highly recommended.  Just a great engineering marvel.  It is a large hydro electric
plant built inside of a mountain connecting a lake and the Ocean... Hard to imagine someone even
coming up with the idea.
