This interactive tool lets you explore quantum vacuum physics, the Casimir effect, rotating fields, cavity QED, and non-linear up-conversion. It also includes rigorous diagnostic tools to test claims of anomalous thrust or vacuum energy extraction.
No over-unity hype. Just honest physics, open source, and educational.
What This Simulator Offers
- Seven interactive tabs covering Casimir forces, rotating fields, cavity coupling, optical cavities, non-linear sideband generation, a predictive device model, and diagnostic tools.
- Real-time parameter sweeps with logarithmic axes, Lorentzian resonances, and Bessel sidebands – the same mathematics used in real quantum electrodynamics.
- Preset famous claims (Podkletnov, Searl, Biefeld-Brown, Manchester spheres) that the tool quantitatively explains using mundane artifacts.
- Plain-English explainers and colour-coded verdicts that teach experimental physics reasoning.
- Fully open source – no hidden agendas, just verifiable science.
What You Can Do in the Classroom
1. Demonstrate Casimir force scaling F ∝ 1/d⁴ live
Students slide plate separation and watch the force update instantly. They see that the vacuum is not "empty" – it has measurable physical effects.
2. Show that a rotating polarization wave is not a magic rotor
The rotating field tab animates a circularly polarised wave. Students learn that a "virtual rotor" is simply a rotating electric field – no moving parts, no violation of physics.
3. Explain why the dynamical Casimir effect is negligible at low frequencies
The device model includes the term (v/c)². With a 500 kHz drive and micrometre-scale rotor, (v/c)² ~ 10⁻¹⁹ → DCE power is astronomically small.
4. Test historical claims with rigorous artifact budgets
Load the "Podkletnov" or "Searl" preset. The tool attributes the claimed weight change to vibration, ion wind, or electrostatic forces. Students learn how experimental physics actually works.
5. Challenge students to design an experiment that survives the leakage budget
They adjust shielding, vacuum level, vibration isolation, and temperature control. Only when residual remains does the verdict become "Unexplained excess". This teaches the mindset of a real experimental physicist.
Why This Matters
A working free-energy device would be world-changing – but it would be a single data point. This simulator is a platform for thinking – a tool that thousands of students and researchers can use to understand quantum vacuum physics, test their own ideas, and avoid the pitfalls that have trapped so many before.
This simulator doesn't hand you free energy – it hands you the truth about your experiment.
Getting Started
Browse the tabs above to explore different aspects of cavity physics. Start with the Casimir Effect tab to see basic vacuum forces, then move to the Device Model to see how to extract power (spoiler: you can't). Finally, try the Thrust & Weight Diagnostic to test real claims against mundane artifacts.
For structured lessons, see the Teacher's Guide and Lab Worksheet tabs.
Go Build Something
This simulator is a playground for ideas – but physics happens in the real world. The vacuum doesn't care about your sliders; it only responds to copper, glass, and voltage.
Build a Casimir demonstrator
Two gold-coated plates, a piezoelectric actuator, and a sensitive scale. Measure the attraction. It's tiny – you'll need patience.
Construct an asymmetric capacitor (lifter)
High voltage, thin wire, aluminium foil. Watch it buzz and lift. Now put it in a vacuum chamber. That's how you learn ion wind from antigravity.
Design a vibration-isolated thrust balance
A torsion pendulum, laser pointer, and camera. One afternoon of shaky data teaches more than a hundred hours of perfect simulation.
The simulator helps you design better experiments and interpret your data. But it will never replace the thrill of seeing a real needle move – or the humility of seeing it not move when you expected it to.
When you do, come back to In Fini and plug your real numbers into the diagnostic tabs. Let the tool tell you: "Unexplained excess" – or "Fully explained by mundane artifacts." Either way, you'll know the truth.
The vacuum is infinite. Your curiosity should be, too.
