I am starting a new velomobile. The last one I built had alot of straight lines and angles. The new one is going to be curved whereever possible and very streamlined. The wheels will be under the fairing. Here is a rough artists conception of what I am shooting for.

Now it is even hotter here in Texas. To increase airflow I took off the top and tried a small windshield. This worked well, maybe too well. I finally took off the windshield altogether. Now I can ride in 95 degree weather in relative comfort.

I found the scoop on the bottom didn't help at all so I put in some Naca ducts. I first tried the ones on the side but found they draw out instead of in. Then I put the 3 vents on top and they work very well.
