Dust and the Eye of Feet

So at Burning Man, there's some dust.
In fact, LOTS of dust.
If you haven't been, you can't understand how much dust.
So I'm building a photography booth.
For feet.
Invariably *dusty* feet.
And it will sit on the ground.
At foot height.
Where all the dust is.
Except for the dust in the air,
which is sometimes so thick
you can't see shit
five feet away.

So my poor camera
which will be in a camera condom
and have other forms of protection
still has one very big problem.
It has to see things
without the lens being cleaned
possibly for days
when the air touching its lens
will be full of dust
at all times.

So I had an idea
involving a computer fan.
An tiny, quiet, persistant fan.
A blessedly 12-volt fan.

Fantastic.*

How much drain will it put on my batteries?
Will a 24/7 flow of air across the lens
convince the dust
it has somewhere else to be?
Only time will tell, my friends.

Only time will tell.
