"Power of a vacuum" is the air pushing inward on the empty tank.
Vacuum doesn't exert any force, it's atoms and particles that exert forces, and they can be strong when there's nothing pushing back.
Typically atmospheric pressure is 14lb/square inch. That's quite a lot. Usually there's an equal pressure inside the tank exerting that same pressure outward, but when it's totally empty that isn't the case, and you get hundreds of pounds of force on that tank.
This is true. Placing a vacuum on one side doesn't create a force pulling up, it creates an imbalance of atmospheric pressure that pushes the object up.

You've never understood physics in the first place. Why start now?
