1. can someone give me an idea or scope on how to make an object float in the air.
2. then how can it be controlled in the air for human use.
no idea is useless and all points are valuable.
The Mythbusters program had an episode where they tested a claim about using static electricity to make a lightweight, kite-like contraption float in the air. There was no visible means of support.
They built the device and it worked. The static created a continual wind which lifted the device off the table.
