minus-squaredickalan@lemmy.worldlinkfedilinkEnglisharrow-up9arrow-down1·4 days agoI know I might get shit for this, but I thought I would share it anyways because you asked. Ultimate Requirement for Ballistic Bovine Methane Production: ~2 kg/s sustained (400x natural rate). LOX Supply: 10 kg/s (requiring cryogenic tanker trucks). Thrust: > 7,000 N (per cow-nozzle). Structural Integrity: Cow reinforced with carbon nanotubes (to avoid rapid unplanned disassembly at ignition). Ignition System: Tesla Coil Spark Plug implanted in the rumen. Trajectory: Vertical launch pad (avoiding trees, barns, UFOs). Final Verdict: Technically possible if you: Treat the cow as a meat-based fuselage. Ignore ethics, biology, physics, and local fire codes. Have a NASA-sized budget and a death wish. Outcome: Success? A charred cow fragment reaches low Earth orbit. Failure? A crater smelling of burnt hair and rocket fuel. Better Use: Flare the methane. It’s cheaper, safer, and the cow lives. Disclaimer: No cows were harmed in this thought experiment. Please do not weaponize livestock. 🚀🐄🔥

Ultimate Requirement for Ballistic Bovine
Final Verdict:
Technically possible if you:
Outcome:

Achieving Ballistic Velocity (The Tsiolkovsky Cow Equation)
The **Rocket Equation** is brutal:
`Δv = Isp * g₀ * ln(m₀ / m_f)`
Where:
* `Δv` = Change in velocity needed (`11,186 m/s` for escape).
* `Isp` = Specific impulse (`~360 s` for CH4/LOX).
* `g₀` = Gravity (`9.81 m/s²`).
* `m₀` = Initial mass (cow + engines + LOX + methane).
* `m_f` = Final mass (just… cooked cow?).
**Assumptions:**
* Engine mass: `300 kg` (mini-Raptor).
* LOX mass: **5x** methane mass (rocket ratio).
* Methane stored: `500 kg` (we’re pumping hard).
* `m₀ = 700 (cow) + 300 (engine) + 500 (CH₄) + 2,500 (LOX) = 4,000 kg`.
* `m_f = 700 kg` (cow, assuming engines/tanks detach).
**Calculation:**
`Δv = 360 * 9.81 * ln(4,000 / 700)`
`= 3,531.6 * ln(5.71)`
`= 3,531.6 * 1.74`
`= ~6,150 m/s`.
**Result:** **6,150 m/s < 11,186 m/s**.
→ **Verdict:** Suborbital cow. Maximum apogee: **~1,000 km** (a very high moo).
→ **Impact Velocity:** **~3-4 km/s** (kinetic energy = 0.5 * 700kg * (3,500m/s)^2 ≈ **4.3 gigajoules**).
→ **Effect:** Creates a **10m wide crater**, vaporizing the cow and any nearby farmers. A true “pasture bomb.”

Because everyone is broke af
Because you aren’t making cow propelled rockets even though you know how.
You missed out the part where cows are frictionless and spherical. Also there are 322 of them in the truck.
