The MOVA Globe rotates peacefully and silently using only the energy from light and the force of the earth’s magnetic field. The MOVA Globe has an inner globe that rotates and is contained within an outer shell, which does not rotate, made of clear acrylic. The thin space between the inner globe and outer shell is filled with a safe, perfectly clear fluid that buoyantly supports the inner globe. The graphic features on the surface of the inner globe are magnified and appear to be on the surface of the outer shell giving the optical illusion that the outer shell is actually moving.
A carefully designed, and highly efficient drive mechanism within the inner globe drives the rotation. Energy for the drive is provided by very advanced solar cells within the inner globe, illuminated by light passing through the graphic. The drive includes a magnetic element that reacts with the Earth’s magnetic field, much as a common compass does, to provide torque to drive the globe. All of these elements work together to create a beautiful and magical object perfect for any room.
How do we create the optical illusion, you ask? And, how does the globe turn without batteries or wires? Here we explain the technology behind the visual magic.
The solar cells are placed inside the globe and behind the globe’s graphics. Most of the ambient light is blocked by the graphics. To produce useful electrical energy from such a low light, these solar cells have to be specially designed and tested.
For the MOVA globe’s motor to get started, and to keep the globe turning, the motor needs a source of countertorque. The MOVA globe uses the Earth’s magnetic field to push against. Think of the needle in a compass. The motor is, in effect, pushing against the needle, which is held stationary by the earth’s magnetic field.
This type of motor is at least an order of magnitude lower friction than current motors used for consumer applications. This makes it possible for the motor to turn, in complete silence, with extremely low power in the micro watt range (a micro watt is one millionth of a watt).>
A very thin layer of fluid between the outer shell and the inner globe makes it possible for the inner globe to levitate, start up, and turn continuously, without ever touching the outer shell.
The optical parameters of the fluid between the inner globe and outer shell, and the distance between the inner globe and outer shell, are designed so the turning graphics of the inner globe is projected onto the outer shell. This makes the outer shell appear to be turning on the stand – in apparent violation of the laws of physics. This technology also makes it possible for the MOVA globe to turn on any surface (except for those made of magnetizable metal, such as iron).
When motion mechanism is placed inside a rotating object. Traditional rotation, such as a fan or an electrical drill, is where motion mechanism is placed outside of the rotating object. Self-rotation may find broad applications in consumer, commercial and industrial markets.
In industrial applications, self-rotation is used to generate motion where the traditional "outside rotation" cannot, such as:
In consumer (business to consumer (B2C)) and commercial (business to business (B2B)) applications, self-rotation may be used to create a broad range of unique and innovative products for decorative, functional and educational uses when combines with the following design capabilities:
