Train

AI Thread Summary

When a train enters a tunnel, the change in air pressure can cause ears to pop, similar to what happens during altitude changes. This phenomenon is due to the rapid compression of air in the confined space of the tunnel. High-speed trains are designed to be sealed to minimize this pressure effect. The discussion also touches on humorous references to train systems but remains focused on the scientific explanation of ear popping. Understanding this pressure change can enhance the travel experience on trains.

how come when a train goes through a tunnel your ears pop a little? is it due to the pressure increasing?

or are my ears just weird

Yes - high speed trains have to be sealed to prevent this.

There's a joke in here about the eu-station tube, but I can't work it out just now.

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...
