Vacuum Motor / Generator - Concept.
By using a large prefab cylinder with a vacuum already pulled inside, we can now use this stored up energy in reverse, we can now use the prefab vacuum like a battery, or storage of energy, just like a motor in reverse becomes a generator, so can wind be blown through or sucked through in reverse in order to move the same magnets past the same fixed stator coils. magnets and electricity are shown to perform inside a [partial] vacuum.
If we created a pressure valve to control the speed of the gas [air] entering the vacuum chamber, which you would need to create the vacuum anyway, we could suck back the air back into the [empty] cylinder THROUGH a rotor/fan coupled with a motor/generator combination in a controlled manner. By controlling the speed of the air entering the vacuum, we can control how fast the rotor generator part rotates, and thus how much energy we can have as output.
In the example images i show tiny [Micro] Aero slits, somewhat like how Tesla used discs for his Turbo, in order to gain maximum rotation speed from air or fluids moving past them, rotating the entire rotor, becoming a flywheel of sorts, powering either a coupled modular motor or generator unit. Using a vacuum like this [potential battery], we could quickly switch between prefabbed vacuum pulled cylinders [coupling/decoupling system], so that we can pull a new [partial] vacuum inside the first cylinder while a second one is being filled up and used to generate rotation and therefore electricity in turn supplying its vacuum pump. We could just use a actual vacuum pump in line directly, depending on if that would cost less or save more energy than it could generate by intelligent usage. This system might perhaps make electricity generation possible or practical in new or different locations.
I guess a vacuum cylinder weighs a lot less than an actual battery, and could be used in places where we could generate electricity, for when space is not the problem but mass is. maybe a couple more use-cases can be thought of. vacuums are said to be very strong, maybe even stronger than we can push wind or blow it, so i predict it can even power multiple in line generators, multiple rotors in a single device if need be, just create a serial vacuum-line and pull air through multiple inline generators.
