Hello Paul,

I would like to thank you once again for the informative and interesting
website. To refresh your memory.  I am building a SeaWind for an around the
world flight challenge making my own fuel as I go. Ethanol probably but
biodiesel is much much easier.  I choose the SeaWind because I will use it
afterwards in exploring the South Pacific. It also gives me more options on
where to land.  I am now completing the body and sanding and sanding.  I
have contacted Mazda Motors (I live in Japan) and am making tentative
inquiries to the cost of a Renesis engine.

I like your drawing of the turbo compound system and would like (with your
permission) to test the concept. Any idea that improves fuel mileage would
be helpful. Of course blade profiles as well as potential heat transfer into
the PRU would be some challenges to overcome.

Perhaps going over 18,000' with a turbo assist may give the best fuel to
mileage range. Your thoughts?

Gee Doug I was just over there. I could have visited.
My wife and I had a wonderful time in Japan and thanks to all the people at Mazda.

You have my permission to build anything you see here as long as you share
any data you might acquire. My guess is 20% less fuel burn is possible
using a turbo compound engine. Perhaps a turbo charger turbine might
be more suitable than the larger diameter turbine shown on the web site.

I am very excited about your project and wish you the best of luck.
