Great job Julian! I purchased your book through Amazon and read it cover to cover. It is nice to see forum members’ photos in book form. I really appreciate the careful research and the time you took to dig up and go through all the published SAE papers and paraphrase them for us. I have been a member of this forum for a long time but I still learned much from your book.

As I was reading, I kept thinking “Where is the build thread for your Insight?” Would you be so kind as to start a thread on this forum and enter your gas log? There a several Insight threads here and I think your build would be of great interest to our readers. You could mention your books in your signature.

Thank you for the praise - and if you could put some of that into an Amazon review, I'd appreciate it.

I don't really have time at the moment to do anything like a build thread, but if some circumstances change, I'll consider doing it.

I don't have a lot of money, and I already have too many books.

I've been thinking about plasma actuators. The middle layer is a dielectric. Glass is a dielectric material. IF, for instance a VW Beetle had a strip of copper along the outer top and sides of the back window, with a second strip inside, and a AC waveform applied across them; THEN would the aircooling be improved? The wake?

Bought the book and have already read it cover to cover. Now to go back and figure what would be best to do...can't do everything.

Again, if you could get the word out there, I'd appreciate it. AFAIK, it's the only aero book ever produced aimed at amateur modifiers.

And re price: if anyone had to buy all the SAE papers I have summarized, it'd cost a lot more than the book price!

Not a technique I've seen others do: https://youtu.be/f6oJ1wjSUI0

Using eroding clay to see very fine detail of airflow patterns.
