A quick science question. Fan into a funnel?

I still think my idea of a jet engine is better, how about injecting some parafin in the exhaust too

That'll blow the. Uck away

That was an Idea I thought about before, but I am not sure if putting more water on there might make things worse/just as bad.

I'm not helping really am I?

The wife's told me about that.



I'll go away now...

I guess a small radio control servo would be the sort of motor, but I think that may actually be more complicated than blowing air over it as I would have to do it twice, once for each lens.

The problem is, the lenses are recessed into the unit about 4 or 5 mm, and has such a wide angle view, anything right by the lens would be continually visible.

The Ram air could be interesting, to try it out, I could mount some sort of pick up on the rear spoiler, and pipe it down, see what happens. Only thing is, I am not sure how to do that, and keep it looking smart.

And the exhaust... Mind you, I always fancied being able to shoot flames out the exhaust..

As you have a lower pressure at the lens all you need is a feed at ambient pressure, inside the car will be higher than outside while you are moving, so a feed from inside should do

Interesting idea. I could start with that, and if it does not work, then go ahead and fit my fan, as the piping will all be in place.
