Is the gravitation source of energy? And yes then can we use this

AI Thread Summary
Gravitation is not a source of energy but rather a means of storing energy, as exemplified by water wheels and hydroelectric power, which rely on gravitational potential energy. The energy utilized in these systems originates from the Sun, which drives the water cycle and elevates water to higher altitudes. Therefore, while gravitational energy can be harnessed, it is derived from other energy sources rather than being a primary source itself. The idea of directly using gravitational energy on a universal scale suggests potential but remains theoretical. Understanding these distinctions is crucial for energy discussions and technological advancements.

Yes, water wheels rely on gravitation for their source of energy. Also hydroelectric power from dams.
 


No - it's not a Source of Energy. It's only a way of Storing Energy. The energy to drive a water wheel has to come from the Sun driving the water cycle, raising water from sea level to a lake / river / dam. That's the gravitational energy that you can use and it's 'second hand', not a source, exactly.
 


i think that if we can use it directly then we can ride whole universe
bcs in whole universe everywhere r gravition
 
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...
