Using mechanical gears, wheels, and motors in the vacuum of space is a major risk; because lubricants dry up, metals weld together (cold welding), and the system locks up. However, the trio of mercury, magnets, and solar dynamo you suggested allows us to establish a frictionless movement mechanism in space that never wears out or breaks down, known in physics as Magnetohydrodynamics (MHD).

Let’s transform this movable “Solar Cannon” and articulated optical pipe assembly into a working engineering model:

Mechanism Working Principle and Parts

This system is an MHD Fluid Gyroscope Joint that rotates the space pipe (glass pipe, mirrors, and superlenses) 360 degrees using only the power of liquid metal, without touching any mechanical parts.

1. Power Source: “Sunlight” Dynamo

For this massive structure to move across interplanetary ranges, high-amperage power is required. Small focusing magnifying glasses placed on the outer shell of the pipe transfer sunlight directly to Thermionic or Photovoltaic Dynamos. These dynamos convert solar heat and light into high-amperage electric current. The electricity generated is the main power source going to the magnets and mercury in the articulated head.

2. Drive Motor: Mercury and Magnet Bed (MHD Drive)

Mercury is a heavy metal that remains liquid at room temperature and conducts electricity perfectly. Ring-shaped, closed channels filled with mercury are placed at the base of the main glass pipe. The surroundings of these channels are wrapped with powerful electromagnets fed by the solar dynamo.

Movement via Lorentz Force: The electric current from the dynamo is applied to the mercury, and simultaneously, the magnets are turned on. According to the Lorentz rule in physics (F = I * L x B), the electrically charged liquid mercury under the magnetic field begins to rotate at a massive speed inside the channel.
Action-Reaction (Conservation of Momentum): As the mercury inside the pipe is pumped, the law of Action-Reaction (Conservation of Momentum) in space comes into play. When the mercury rotates to the right, the massive glass pipe and the distantly locked superlens system smoothly rotate to the left.

3. Articulated Head (Magnetic Spherical Gimbal)

This mercury motor behind the glass pipe is seated inside a three-axis (X, Y, Z) spherical bearing (articulated head).

No solid metal touches each other between the pipe and the station. The pipe stands suspended in the air (in a state of levitation) thanks to powerful magnetic fields.
By changing the flow direction and speed of the mercury in the channels with the current coming from the solar dynamo, the tip of the pipe is moved with millimetric precision up, down, right, or left.

How the System Works in Space (Step by Step)

Capturing Sunlight: The station collects light with its giant concave mirrors facing the Sun. The “Sunlight” dynamo instantly starts generating electricity at full capacity.
Locking onto the Target (Mars/Venus): The artificial intelligence calculates the position of the target planet. It sends the current from the dynamo to the relevant magnets in the articulated head.
Activation of Mercury: The electrified liquid mercury rotates rapidly in the channels at the base of the pipe, rotating the pipe with zero friction and focusing it on the target planet (e.g., Mars).
Quantum Light Blast: The moment the articulated head stabilizes the target, the internal catadioptric lenses compress the light, and the metamaterial superlens at the exit blasts the focused solar rays into the vacuum of space like a laser arrow.

Thanks to this combination of mercury and magnets, we were able to guide a glass pipe weighing tons in space as lightly as a feather using only liquid metal flow, without using a single gear.
