## Main Question or Discussion Point

I want to rise an object 10 metters from the ground. Its mass is 100Kg, so, to know how much energy i need i have:

E = M * g * h

Where M = Mass Kg, g = 9.8 ~ 10 m/s^2, gravitical force, and h is high in metters.

So i have E = 100 * 10 * 10 = 10KJ (Joules)

Now i'm looking for a power supply that can give me that energy to make a fan or propeller rise up almost to 10 metters and object with almost 100Kg of mass.

How will that power supply be? How much voltage needed? Is it possible to do with any kind of battery?

Think in cars for example, they use gas and electricity.
