Can We Transfer Energy from the Sun? - James Bond "Day Another Day

AI Thread Summary
Transferring energy from the sun to Earth is theoretically possible, as energy transfer occurs in various forms, such as solar power. However, the practical implementation of such technology raises significant scientific and technical challenges. Current methods of harnessing solar energy involve capturing sunlight and converting it into usable energy, rather than direct transfer. Safety concerns also arise with any large-scale energy transfer systems, especially if they are weaponized. Overall, while the concept is intriguing, the feasibility of safe and effective solar energy transfer remains speculative.

Dear PF Forum,
I know that this question is purely speculative. And I should have googled it, but...
In James Bond film, "Day Another Day", we saw that the villain, portrayed by Toby Stephens tries (and I might say, succeeds) to tranfer energy from the sun to some spot on earth, whether it can be used as a weapon is beside this question.
My question is,
A. Is it scientifically possible to transfer energy?
B. Is it technically possible to (safely) transfer energy?

Sure, energy is transferred all the time.
 
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...
