Thanks really this helped me a lot. Could you explain me a little more about the ground effect? Are there any propeller alternatives that could be more efficient like magnetism?

I was really wondering if the number of blades in a propeller influenced the power it has, are too many blades bad also? At last I will like to know how much force will you need to elevate a person 1 meter over the ground an mantain the person at that height?
