Vacuum Container for Levitation;- summary


Important Note:I conceived this idea/invention in South Africa in 1978, as a totally original idea, pondering the possibilities and difficulties in creating a vacuum container as a means of levitation in the air. On the 5th Aug 1997, living in Brisbane Australia, I finally submitted a Patent Application as outlined below. I have had to retype the pages below for my website, but have the original documents, including the police fraud investigation against someone in the Patent Office, who may have illegally passed on my patent application to outside source(s) at that time. A debilitating depression, starting some years before, became life threatening from early 1998 onwards, and halted me from progressing on any of my ideas including this application.




Brief Description & Claim

The invention is described in the following statement:

The creation and use of a vacuum or partial vacuum within a container or vessel to achieve levitation of this container or vessel in the air.

Terms and Their Meaning(s) (relating to the Brief Description above)

  • The word “vacuum” is to mean vacuum or partial vacuum.
  • The word “container” is to mean a container or vessel and may include attachments and cargo including people. “VC” will mean “vacuum container”.
  • The word “levitate” or “levitation” is to mean the ability of the vacuum container to lift or move upward in the air to a level in the atmosphere where it achieves buoyancy or a floating state.
  • The word “air” is to mean air and/or atmosphere.

The Underlying Principle(s)

The underlying principle behind the ability of the vacuum container to levitate is that the weight of the vacuum container is to be lighter than the volume of air it displaces to allow lift in the air. When the vacuum container (VC) rises no further in the air the weight of the VC will be (approximately) equal to the weight of the air it has displaced and will then achieve a floating or buoyant state. An increase in the volume of the vacuum will achieve lift to ascend to a greater height in the air. A decrease in the volume of the vacuum will achieve descent to a lower height in the atmosphere, under the same or similar atmosphere conditions.

Creating the Vacuum

One of the methods for the creation of the vacuum within a container can be achieved by the pulling apart (or away) of one surface or plate from another surface or plate in such a manner that no air is able to enter the space between these surfaces or plates.

Another method of creating the vacuum within a container is to assemble and seal a container within a vacuumed room or space in such a way that a vacuum is sealed within the container. Other methods for creating a vacuum within a container will not mitigate this patent.

Optimum Achievement and Aims

The optimum (but not necessary to this patent) achievement or aim will be to create as small a vacuum container (s) as possible, to weigh as little as possible, with maximum lift or levitation ability. A (large) number of (small) VCs held together as a levitating vessel has the advantage of safety i.e. if any possible malfunction of a small number of VCs occurs. Adjustment of the volume will be a method of altering the height in the air at which the VCs float, i.e. to rise further from or descend closer toward the ground or relative surface below.


The following example uses described for the levitating vacuum containers are not to be considered the only uses to be covered by this patent.

  • Levitations of enormous platforms or structures into the atmosphere, whether tied back by line to the earth or not. The possibilities for uses of such floating structures may include sky restaurants, hotels, viewing areas, launching of rockets into space, skydiving etc. Some such platforms may require vast numbers of smaller VCs.
  • Recreation activities where a single or collection of a number of vacuum containers are used to lift people in much the same way as hot air or gas balloons, for ‘flight’ in the air. Additional attachments may be added to achieve controlled direction. Adjustments to the volume of vacuum will achieve ascent and/or descent. By achieving a durable VC that resists penetration of air, the advantage over hot air or gas filled balloons is that there is no requirement to replace gas or fuel. The VC is a permanent (or long term) levitating object, or group of objects.
  • Levitation of objects for advertising, sport, games etc. This may involve tying the VCs by rope or line back to another object or person on the ground.
  • Support of a lightweight roof structure over a space below, such as a stadium, using the required number of VCs attached to the roof fabric.

Design of the Vacuum Container

The following design methods, information and description are not to be construed as the only methods, information and descriptions to be covered by this patent for the design of the vacuum container or method of achieving a vacuum within a container. Shape, materials, size and method of construction may vary significantly to achieve levitation of a variety of VCs in air.

Refer to the diagrams attached to illustrate the following design types:

  1. Simple Shell Structure

This design illustrates a method for creating a vacuum containing structure based on a rigid cylindrical (or other shape) outer shell, sealed both ends, which can withstand outside air pressure. The total weight of this structure is to be lighter than the volume of air it displaces, to levitate. Possible adjustments to increase and decrease the volume of vacuum may be structure.

  1. Complex Shell Structure: Internal Supports

This design illustrates a method for creating a vacuum contained within an airtight structure based on internal supports to aid the bracing of the outer shell against air pressure and retain the internal vacuum. The total weight of this structure is to be lighter than the volume of air it displaces, to levitate.

  1. Complex Shell Structure: External Supports

As item 2 above, except that the support(s) for the outer rigid shell(or flexible skin) is external to the outer shell. A combination of external and internal structural support may also be created. The same general rule for levitation applies.

  1. Structures in a Vacuum or in Space

A lightweight sphere (or other container shape) of glass, plastic or other material can be created and then the inside air, gas or liquid (used to create the sphere or other shape) be released within the vacuumed room or ‘outer’ space, in such a manner that a vacuum will then exist within this sphere (or other container shape). This sphere can then be sealed and released into the air.

It may be possible to create and release such spheres (or other container shapes) in and from ‘outer’ space in such a manner that they fall toward Earth into the atmosphere, where they will reach a level of buoyancy, and float. These spheres (or other), which may be very large, could then be collected from the atmosphere eg using pre-attached lines or other methods.
