Pressure Differential Propulsion

When you were getting on and off the air mattress, your weight was the applied external force.

I fully understand that, and I must say your wrestling match made me chuckle me chuckle this morning. TGIT :)

So, you will need a weight to place on the bladder to compress it and extend the appendage.

How will you move the weight on and off of the bladder?

How about an electric hoist?

Well, as long as you have an electric motor handy, why not just use it to do the work and get rid of that silly bladder and appendage?

What I'm thinking, (and believe me that gets me in a LOT of trouble some times,) with the technological advances in nano technology, and I'm by no means in this field, a very minimal amount of pressure could be applied to a perfectly sealed bladder to propel an object from point "A," to point "B," and in turn, back again.

I'm not trying to gain any type of financial gain from this Idea. These are Simply the things I ponder in my spare time. Maybe someone can take this idea to and run with it.

It would be neat to see the mathematical formula for this theory.

Let's say for stttts and giggles, when the small appendage, attached to the air mattress reached its fully extended state, it flipped a switch that released a weight, that applied pressure to an identical air mattress assembly directed back to a switch that releases a weight over the first air mattress we started with.

Would it cause an explosion, an implosion. or have no effect at all?
