Condensation in vacuum container

AI Thread Summary
Condensation in a vacuum-sealed lens can blur vision, especially if moisture is trapped inside. Using rice or silica gel is a common suggestion for drying out moisture, but it may require drilling a hole in the lens body to insert these drying agents. Simply placing the lens in a dry environment may not be sufficient to eliminate the condensation. Drilling a hole could allow for better airflow and evaporation of the trapped moisture. Addressing the condensation issue is crucial for optimal lens performance.

Hi,

I'm building a lens and stupidly rinsed one component before putting the lens body together with epoxy glue. Now when I leave the lens in the sun the trace of water left in the vacuumed lens body turns into condensation and blurs out the vision. I've seen loads of forums suggesting using rice or silica to dry it out, will this work for me? Or will I need to drill a hole in the lens body to air it out again?

thanks
Ian

any help would be greatly appreciated
 
Wouldn't you have to drill a hole to put the silica/rice in as well?
 

Thread 'Why can't Solar panels be hemispherical, or a curved strip type?'

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
