Seriously though that question is to vague to be of any use. What is the application?

Sorry about that. I'm measuring the force of impact by a paintball at various distances using different types of paintballs (different shell to liquid ratios). This is actually part of a larger study in which I'm studying bruise healing. I'm creating bruises under controlled application of paintball. But I'd like to determine the level of force, so that I may minimize it for participant comfort. So I'm looking for an inexpensive force sensor to measure paintball impact. Thanks.
 

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...
