Hello all
We are launching a camera up in a high altitude balloon (no rockets invovled but high altitude, I figured you all know about that) to hopefully 80 000 feet. We are worried about frost forming on the windows and blocking the veiw.
This is going to be a long flight, on the order of 3 or 4 hours, so sustained power consumption (heater) might be an issue, but there is capacity for batteries if this is the best idea. This is still in the concept stage, so different materials for the window are a definate option.
We have already tried a couple of things that do not work, including those silica gel drying salts, and a presurized window box.
Any previous experiences with this sort of thing, or If anyone has some ideas, I would be delighted to hear. Thanks in andvance for all your help
Jack
