I added a mirror instead of a light detector after the shutter line to my setup to test the speed of light unidirectionally and simultaneously verify the symmetry of the speed of light in all directions.

The detector is now at the beginning of the line.

Everything has been done to bring mathematicians and their games into reality.

THE DEVICE

A straight line of optical shutters is placed at equal distances.

A laser on the left shines continuously along the line.

On the right, a controller sends a traveling wave of shutter‑opening signals using light.

The control signal must be light, because only light propagates at speed c.

Any slower signal would break the synchronization and destroy the traveling wave.

The phase of the traveling wave is tuned so that each shutter opens exactly when the forward‑moving laser light reaches it.

This creates an optical green wave: the light passes through the entire line.

On the right end, instead of a detector, there is a mirror that reflects the light back.

OPERATION

Forward

light moves at speed c,

delays between shutters are fixed,

the traveling wave opens shutters at the correct moments,

the light passes through the entire line.

Backward

the mirror reflects the light,

it travels back at the same speed c,

with the same delays,

but the traveling wave was tuned only for forward motion,

backward arrival times do not match the phase,

shutters are closed,

the light does not pass back.

Rotating the entire setup by 180° gives the same result:

forward passes, backward does not.

THE MATHEMATICAL TRICK

Some theorists claim:

You can choose a time‑synchronization convention where

one‑way speed of light forward = c/2,

and backward = infinite.

In that convention, backward light supposedly

arrives instantly, with zero delay.

Therefore, if the shutter line is

momentarily all open at once,

the “infinitely fast” backward light

should pass through completely.

They also claim:

“No experiment can test this, because any one‑way measurement requires two synchronized clocks.”

HOW THE DEVICE CUTS THROUGH THIS

My device:

uses no clocks,

uses no synchronization,

uses no remote observers,

does not depend on coordinate conventions,

operates entirely in one local physical time.

It shows:

backward light travels at the same speed c,

real delays exist,

the traveling wave phase does not match backward motion,

shutters are closed,

backward light does not pass,

no “instantaneous return” occurs,

no “infinite speed” appears.

Even if the entire shutter line is open for a brief moment,

the backward light cannot “appear everywhere at once,”

because it physically moves at speed c,

and the traveling wave has already moved on.

RESULT

The device demonstrates physical reality:

one‑way light speed cannot be skewed,

no “infinite backward speed” exists,

no “instantaneous return” happens,

and this is experimentally testable,

without two clocks and without philosophical tricks.

The mathematical fantasy survives only inside their abstract synchronization convention.

My device operates in real physical time, where light always moves at speed c.

For decades we’ve been trying to store energy by “lifting a weight.”
Towers, mine shafts, rail systems - all of it tons of concrete and metal.
Height costs billions.

And the solution was hanging… in the air all along 

 The atmosphere is a free 10‑km “mountain.”
Archimedes works here too: light things float, heavy things sink.

 A dirigible is a weight that wants to go UP.
We simply attach its tether to a heavy block on the ground.

Day:
solar panels pull the airship down, charging the system.

Night:
the airship floats up, spinning a generator.

Result:
- no expensive tower,
- no expensive mine shaft,
- no expensive mountain rail system,
- just cheap components - a tether, an airship, a junkyard truck filled with sand as the anchor, and physics.

The low lifting force is compensated by the length of the path.
Because the air itself is the free tower, the free rails, the free shaft.

Wind stability comes from the cigar shape and the airship turning like a weather vane.

A simple mechanism clips small float‑balls onto the tether during unwinding and removes them during winding, storing them in a cassette - so the tether’s weight is compensated.

An airship with 1 ton of lift × 5 km = ~13.6 kWh.
Enough to get through the night without batteries.

This is the cheapest gravity storage system you can install even on a farm.
And scaling it is trivial - just add more airships on tethers. 

I simplified the my setup, and now it’s no longer two wings with the controller in the middle.

A single wing is enough, with the control light moving in the opposite direction relative to the beam being tested for speed through the shutters line.

Step‑by‑Step Description of the renovated Device and Operation of My One‑Way Speed‑of‑Light Measurement Method

1. Components of the Device

1.1. Line of Optoelectronic Shutters

A straight linear array of N identical shutters (e.g., 100 units).

All shutters are spaced at equal distances.

Each shutter opens for a very short moment when triggered.

1.2. Constant Light Source

A laser that emits continuously, without pulses or a defined start moment.

The beam travels along the shutter line.

1.3. Light Detector

Placed at the far end of the shutter line.

Detects whether the beam successfully passed through all shutters.

1.4. Controller

Located next to the detector.

Generates a sinusoidal signal.

Sends this signal to the shutters using control laser beams that propagate in the opposite direction to the tested beam.

Creates a traveling wave of shutter openings.

2. Operating Principle

2.1. The laser beam is always on

No start pulse, no synchronization event.

The method does not rely on knowing when the light “began” its journey.

2.2. The controller creates a traveling wave

The sinusoidal waveform is distributed so that shutters open sequentially, forming a moving “window.”

2.3. Light passes only if the wave matches the beam speed

If the traveling wave moves exactly at the same speed as the beam,

the beam reaches each shutter when it is open.

If not, the beam hits a closed shutter and never reaches the detector.

2.4. The detector confirms only successful synchronization

A visible spot on the detector means:

the traveling wave was synchronized with the actual one‑way speed of light.

3. What the Method Measures

3.1. One‑way speed of light

Control light travels in one direction.

The tested beam travels in the opposite direction.

Both interact with the same shutter geometry.

If speeds are equal → synchronization is possible.

If speeds differ → synchronization is impossible.

3.2. Self‑consistency of opposite light paths

The method relies on self‑consistency:

control light defines shutter timing,

tested light must “catch” the openings.

If their speeds differ, the phase relationship drifts and alignment fails.

4. Why the Method Works

4.1. No two clocks → no synchronization problem

All timing is local.

No remote clocks exist.

No Einstein synchronization is required.

4.2. The controller does not measure time-of-flight

It simply adjusts the wavelength of the traveling wave.

When the wave matches the beam speed, the beam passes.

4.3. If light speeds differ in opposite directions → shutters never align

The control light sets the phase.

The tested light must match that phase.

If their speeds differ, alignment is impossible.

5. What Successful Transmission Proves

If the beam reaches the detector, it means:

The traveling wave moved at the same speed as the tested beam.

The control light (opposite direction) has the same speed as the tested light.

The speed of light is symmetric in both directions along the shutter line.

If anisotropy existed, synchronization would fail.

6. Conclusion:

This experiment is fundamentally different from all previous attempts to measure the one‑way speed of light because:

We begin the experiment knowing nothing and assuming nothing about the speed of light or its directional symmetry.

There are:

no preset assumptions,

no synchronization conventions,

no built‑in symmetry conditions.

All information comes directly from the experiment itself.

By manually adjusting the controller’s sinusoidal waveform — turning the tuning knob and changing the wavelength of the shutter‑opening wave — we search for the condition where the system becomes self‑consistent and the light finally passes through the entire shutter line.

When self‑consistency is achieved, the system reveals the true one‑way speed of light in that direction.
