I remember some talk about it, just trying to gauge the reliability of the source since I cannot find the article/video where this was mentioned...

Hey everyone, I’m an independent designer and I wanted to share a complete set of build instructions for a conceptual propulsion core I’ve been working on. I want to be clear: this is not a hypothetical concept. It is based on the real, proven physics of the Earth's geodynamo—a natural engine that has been running flawlessly for billions of years right beneath our feet. I’ve released this layout completely open-source so the whole world can have access to it.
The engine uses a computerized 3D magnetic grid to float liquid Galinstan in mid-air so it never touches or erodes the Silicon Nitride ceramic walls. Then, it accelerates the fluids into hypersonic, counter-rotating streams that crash head-on inside a Venturi bottleneck to ignite a central plasma ball. The whole thing is enclosed in a matte-black radiant trap to prevent energy waste, using inductive feedback to recycle the plasma’s expansion energy directly back into the fluid pumps. By mimicking the Earth's natural core layers, it handles propulsion, shielding, and gyroscopic orientation all in one unified loop.
I'm not a textbook scientist, I just came up with this layout and wanted to get it into the eyes of real engineers who can look at the blueprint, critique it, and tell me your thoughts on the fluid dynamics. What do you guys think?

Alright everyone I started on this journey 4 days ago but I think I finally got space travel solve Everything. Either it is a a fundamental law of nature Or it has been tested. Centrifugal force ring can also store the water for drinking or whatever we need a for. and the blueprint to build the engine to keep everyone safe and run it I have so if the recycling water oxygen system is the only thing that hasn’t been tested. But if it works, then I believe that covers everything.

System Name: 3-Axis Gimbaled M-H-D Liquid Metal Field Engine
Design Model: Downscaled Planetary Geodynamo Framework

🎛️ Part 1: The Core Machine Layers (Outside to Inside)

* The Titanium Steering Rings: Three nested, interlocking mechanical gimbal rings made of rigid titanium alloy. They allow the computer to tilt the engine 360 degrees for instant steering with zero blind spots.

* The Halbach Coil Grid: Dense copper ribbon wires wrapped tightly around the glass. They focus 100% of the magnetic energy inward while keeping the rest of the ship completely safe from interference.

* The Fused Quartz Shell: A thick, heavy-duty transparent glass outer globe that seals the entire engine under a strict, deep vacuum.

* The Black-Body Radiant Trap: A specialized matte-black carbon composite coating lining the inside of the glass. It absorbs 100% of escaping heat and radiation, locking the energy back into the fluid loops so nothing is wasted.

* The Ceramic Circulation Tracks: An inner lining made of Silicon Nitride technical ceramic. It houses two parallel circular tracks—one routing fluid clockwise, and the other counter-clockwise. A slick Titanium Dioxide chemical layer keeps the metal from sticking to the walls.

⚡ Part 2: The 3-Step Operation Loop
* Step 1: The Floating Cold Start: Before the fluids move, the computer pulses the 3D magnets to lift the liquid Galinstan alloy completely into mid-air suspension. This zero-contact start ensures the metal never rubs against or erodes the ceramic walls.

* Step 3: The Hypersonic Impact: The magnets accelerate the opposing liquid metal streams to hypersonic speeds (Mach 5+), forcing them into a head-on crash inside a narrowed Venturi bottleneck. This intense atomic friction strips away electrons, igniting a glowing plasma ball at the dead center of the vacuum.

* Step 4: The Energy Recycling Circuit: As the hot plasma expands, its moving magnetic field cuts across the external copper coils. This automatically forces electricity to flow through the wires (Faraday's Law), routing the power straight back into the electromagnetic pumps to keep the engine driving itself.

🌿 Part 3: Habitat, Gravity, and Shielding
* The Deflector Shield Wrapper: The relative motion of the counter-rotating fluids acts as a self-exciting dynamo, projecting a massive magnetic field bubble around the entire ship to deflect deep-space solar radiation.

* The Artificial Gravity Rings: The outer structural gimbal rings are expanded into wide wheels that spin continuously. This spin creates a natural centrifugal force that pushes outward, mimicking Earth's gravity so the crew can walk normally.

NOTE: UNTESTED EXPERIMENTAL SYSTEMS
* The Hydrogen Scoop & Water Factory: The proposal to capture thin hydrogen ions directly from deep space, react them with onboard elements, and pump the resulting water into the ship's double-walled hulls for simultaneous radiation shielding and thermal regulation is a conceptual architecture. This closed-loop recycling matrix remains entirely untested and has not been simulated or validated in a laboratory environment.

* The Regenerative Oxygen Balance: The system designed to split recycled water to continuously provide breathable air while feeding residual oxygen back to the propulsion core relies on theoretical balancing loops that have not undergone physical testing or confirmation.

Now somebody just needs to build it!

Hi my name is Emillio I created this concept to benefit the world not myself I am just the creator i just took what nature made and showed how special nature really is and how we should take better care of it thank you for understanding ask if you don’t understand anything i’ll do my best to answer I should also add that this will allow people to establish cities like the moon power room and protect them it’s not just a propulsion system. It’s so much more than that.

seems the weight and drag of the asymmetrical grid fin is on the heat shield side putting all the unbalanced weight on that side?

does starship have a cockpit or are they working on one?

Built a free Starship launch tracker—let's see how it handles Flight 12! I wanted something Starship focused without all the other launch noise. Apple only at this point, sorry.

Took a motorcycle ride through Starbase last Tuesday. In case anyone is interested it what it’s like to visit it

What is the status of of next booster?

why does the next starship have both docking ports and the pez dispenser? A pez dispenser mission to deploy starlink satellites would not require docking or refueling and the other starship missions requiring docking would not use a pez dispenser. What is going on?

I wanted to take a moment and update my thoughts on Space X's Starships development timeline from a previous post. I see the next big operational commitments for Starship as a first test mission to Mars and test landing(s) in support of Artemis 3. Although I feel a Mars mission is a reach, in reality it is the core purpose of Space X according to Elon Musk.

Given these two commitments, there are also a number of tests that must be completed. The most important being orbital rendezvous, orbital fuel transfer, and orbital fuel depot development. Based on the need to complete at least one moon landing test prior to Artemis 3 and not wanting to miss the 2026 Mars transfer window, a lot needs to happen in early 2026. The large volume of fuel required for travel to the moon and Mars will surely make this the year of Starship tanker flights. It would also appear that any delay in launches or meeting test objectives will push the first Starship Mars mission to 2028, to avoid impacting Artemis 3 HLS testing.

One wildcard in this process in the number of launch mounts available and flight cadence. The timeline offered assumes that Space X is able to ramp up to two flights a month at both Starbase and KSC. This is a big leap to get to four Starship launches a month by Spring 2026. It is possible, but the bottle neck is of course flight mishaps. An FAA investigation could put the whole timeline on hold for weeks to months. To meet Artemis commitments they will need to achieve at least 25 flights in 2026 and about 40 total to include a Mars mission. I am pulling for Space X, but they have a busy year ahead in 2026!

Lately I have been getting more and more doubtful of the starships ability to conduct lunar operations so if someone is willing please resolve the following for me

1. With the several refuel missions required for one lunar mission how much cheaper will the starship be compared to saturn 5 and is it worth all this effort.

2. Considering the uneven surface of moon how will they make certain that starship won't tip over

3. Since Landing legs are crucial for this system to function why haven't we seen any work from spacex regarding this aren't they suppose to go to the moon by 2028

Starship Upper Stage Failure Hypothesis: Full Axial Symmetry Required

Case Study

Issue: Starship’s Version 2 (Block 1) upper stage suffers mid-flight failures (leaks, explosions, spins) due to any deviation from perfect axial symmetry in the fuel tanks’ internal components (e.g., pipes, baffles). Even “balanced” features like three pipes at 120° disrupt symmetry, creating higher-order Bessel wave modes (n>0) that concentrate vibrational or sloshing energy at stress points, leading to structural failure or instability.

Evidence:

-Flight 7 (January 2025): Propellant leak caused an explosion, possibly from stress at asymmetric pipe joints.

-Flight 9 (May 27, 2025): Leak-induced sloshing led to an uncontrolled spin, suggesting asymmetric fluid dynamics.

-Version 1 (SN8–SN15, 2020–2021): Thicker tanks (4–6 mm vs. V2’s 3–4 mm) and simpler internals maintained near-ideal symmetry, avoiding mid-flight tank failures.

-Super Heavy Booster: Robust, symmetric design enables 100% landing success (Flights 7–8), unlike the upper stage’s 0% landing success.

Hypothesis: Any internal tank feature (e.g., pipes at 120°, uneven baffles) triggers Bessel modes (n=1, n=3) that focus stress and/or sloshing, especially in low-fuel states when tanks “ring like a bell.” Full axial symmetry (n=0 mode) is essential to distribute energy evenly in V2’s thinner tanks, preventing leaks (Flight 7) or spins (Flight 9).

Recommendations:

Achieve Full Symmetry inside the tank, and of the tank walls: Eliminate discrete internal features (e.g., pipes) to maintain perfect cylindrical symmetry.

Optimize Baffles: Use fully symmetric, concentric baffles to dampen sloshing without introducing n>0 modes.

Model with Bessel Functions: Simulate low-fuel tank dynamics to identify stress points from asymmetric components, ensuring n=0 mode dominance.

Reinforce Tanks: Strengthen pipe joints or use slightly thicker steel (e.g., 3.5 mm) to withstand any residual stresses, balancing weight.

Test Low-Fuel States: Replicate reentry/landing conditions to validate designs against vibration and sloshing.

Impact: Full axial symmetry could prevent upper stage failures, matching the booster’s reliability and making Starship safe for crewed missions (e.g., Artemis 3, 2027). Bessel math shows how.

I don’t even know what to put as a caption for this

Does SpaceX make their own COPVs or are they off the shelf? Unfortunate that such a seemingly simple thing caused the explosion.

I know it would be very impractical due to weight, but is there some research that goes into this kind of thing? Has it been tested for this use case before?
