I know it's June but I want to be ready by December!
I found this page about blowing an HPV fairing and it intrigues me very much. http://www.wisil.recumbents.com/wisi...hpvbubbles.htm
I don't ride a recumbent bike but I would like to try a fairing on a bicycle. I rode all last winter and considering I live in Alabama the winters are not what you would find up north but it still gets cold and it can be miserable in the wind. Having a bubble up front to draft behind sounds like a good idea but having never road a bicycle with a fairing I have no idea what it would be like. Anyone here ever does this? I would think if it works on a 2-wheel recumbent bike it should work on a standard bike as well. I have several different bikes to choose from that could have the fairing mounted to it. A classic roadie Bridgestone that’s made for speed. A Suteki café bike with finders, chain guard, rear rack, and Moustache bars, or a Specialized Cross Roads hybrid. I am leaning toward doing the hybrid bike as it's my commuter and it has all the eyelets that would make mounting the fairing easiest of them all. Am I nuts for thinking about mounting a fairing for winter use?
Not nuts, biggest problem is storage if you use bike lockers, and some adjustment in riding for side winds.
Do a forum search, some have used them. They were experimenting last year and should have some experience now.
Zipper for one makes them, there are others. Zipper makes both fairings for road bikes and mtn bikes. Cost is about $300 to $400. Some issues with lights. Smoke ones will decrease lighting, clear will have to be cleaned for light thru, some reflection, may require mods, ie light holes, to avoid this.
I am going to take the plunge and build the oven and blow some fairing bubbles. I am going to start with the cheap ABS material until I prefect the technique and a design. I am defiantly going with the hybrid bike for fairing use. I can mount my lights in the fairing. We have very little public transportation here and no bike lockers or even racks in front of any of the local business. Most retailers let you bring your bike right in the store and park it inside as so few people bike commute here so rack use is no problem as well. I will post pictures when I have a good bubble and have the design correct for my hybrid.
If you're going that route, google for bikes and fairings for ideas. There are some besides zzipper, I just don't remember their names. One in Mich looked interesting. Check out zipper, they have interesting photos of uncompleted experimental fairings. Also look at motorcycle fairings. Often they have 3 inch holes on left and right side with open/close plugs. They do this to increase ventilation. But there is no reason you couldn't use this idea for a light opening. Normal daylight riding, with plug in, for nighttime, pop the plug so you have no light loss and reflect back into your eyes.
Just for fun I bought a used small light duty universal fit motorcycle
windshield for my winter bicycle a couple years ago. I mounted it on
the handlebars really easy with the result looking not a bit out of
place. Kinda looked good actually. Much to my suprize this little
windshield makes winter riding a lot more pleasant by blocking
much of the cold wind from my torso & face. Since I ride slower
in winter the drag doesn't bother me that much.
Cruise E-bay for universal windshields to see what you can find.....cheap.
My school actually has a hpv design team, which uses a fairing on their recumbent bikes, gets them to about 45-50 mph average during the sprint events. They use carbon fiber over a custom sytrofoam mold (very expenzive) but its light and it works great.

Not much. In the 1989 RAAM two four-man relay teams raced two faired up-right bikes across the USA from Huntington Beach, CA to the west MUP onramp of the George Washington Bridge near new York city. Six days, 5 hours and ~ 6 days, 14 hours. In the 2006 the top 4 man relay teams did it in about the same time without fairings. I've used a fairing on an enclosed recumbent in winter in Denver and it frosted over almost immediately. I stuck with a bike and goggles after that. I can see using a bike fairing thru a cloud of locusts, otherwise . . .

You know how to keep it from frosting over, don't you? Quit breathing!
