I was perusing the April 1999 issue of Yachting Magazine and saw and
interesting type of tubing on page 61- a co-axial copper nickle tubing used on
marine air conditioning units- perhaps it might be useful for some type  of
water/ oil heat exchanger?

I was fortunate to see Chuck Harbert's turbo three rotor Velocity today- 
a really well thought

should have a very nice aircraft indeed when he gets done.
