uDrive - Fuel-free on-site power, measured (not magical)

What it is

• A stationary mechanical power cabinet that turns the stored energy of a pre-loaded coil spring into steady, useful shaft torque, which then drives a standard electrical generator.
• Fuel-free and quiet. No combustion, no exhaust, no fuel logistics.
• Hybrid by design. Drops in alongside the systems you already use (grid, batteries, generators, fuel cells) to add clean base kilowatts on site.
  

How it works

Like pushing a swing at the right moment: uDrive uses precisely timed contact geometry to steer mechanical forces so the spring’s elastic energy becomes smooth, time-averaged rotation. The timing/geometry do the “push at the right angle,” turning rapid force changes into a steady output a generator can use.

What it isn’t

• Not a battery replacement. Batteries excel at fast spikes; uDrive supplies continuous base power.
• Not a fuel engine. There’s no combustion cycle.
• Not “over-unity.” All energy flows are metered (input from the spring, output at the shaft/generator, and losses). We improve conversion quality; we do not create energy from nothing.

Why it matters

• Resilience without fuel. Keep essential loads alive with quiet, on-site kW.
• Lower runtime on existing assets. Fewer generator hot starts, smoother duty cycles, less wear and noise.
• Simple hybrid fit. Let batteries handle fast transients while uDrive carries the steady baseline.

Evidence so far

• Independent lab measurements. High-precision torque testing at EMPA (Swiss Federal Laboratories for Materials Science and Technology) observed the effect on an early, non-optimized prototype.
• Transparent discipline. We verify with controls any engineer expects: a symmetry-null test (if geometry/timing are symmetric, average torque collapses near zero), rigidity sweeps, and materials/tribology upgrades¹—then re-measure.

How we measure (classical mechanics, instrumented)

• Work per cycle: Wcycle=∮τ(θ) dθWcycle​=∮τ(θ)dθ
• Cycle-average torque: τˉ=Wcycle/(2π)τˉ=Wcycle​/(2π)
• Average power: Pˉ≈τˉ ωˉPˉ≈τˉωˉ
• Mechanical efficiency: ηmech=Wout/Winηmech​=Wout​/Win​ (losses include friction, bearings, seals)

Controls we use:

• Symmetry-null: with symmetric geometry/timing (no phase bias), τˉ→0τˉ→0.
• Rigidity & tribology sweeps: stiffer drivetrains and improved contact pairs should increase ηmechηmech​ under identical protocols.
  All quantities are metered (torque–angle ττ–θθ, speed, electrical output) with shared procedures and uncertainty bands.

Where it fits first

• Homes & small buildings: essential circuits and background loads; batteries cover short peaks.
• Critical facilities & microgrids: quiet baseline power that trims demand peaks and reduces generator hours.
• Industrial sites & data rooms: steady kW for auxiliary loads; smoother operation for the fleet you already trust.

What’s next

• 1 kW-class demonstrator with upgraded rigidity, bearings/coatings, and closed-loop timing.
• Hard metrology at every gate: cycle-average output, efficiency vs. design changes, runtime stability, and clean integration to standard controls.

Strong Force Engineering & Conversion (SFEC)

uDrive is engineered in classical mechanics; any deeper SFEC coupling remains a research hypothesis and is not required to understand or evaluate performance.

[1] We improve materials, surfaces, and lubrication at all friction/contact pairs to reduce friction, wear, and stick–slipand raise mechanical efficiency. Scope includes: Materials & heat-treat (e.g., upgrade Al/standard steels → hardened tool steel, 17-4PH/440C, titanium; ceramic/hybrid bearings where appropriate); surface finish & micro-geometry (superfinishing, Ra < 0.1 µm; edge rounding/crowning; controlled fits/preload; Hertzian contact optimization); coatings(DLC, TiN, MoS₂, CrN, hard anodize, nitriding—to lower μ, wear, fretting/galling); lubrication strategy (viscosity selection, EP/AW additive packages; boundary/mixed/hydrodynamic regimes matched to speed/load; oil vs. grease, dosing, sealing systems); bearings/seals (precision classes—ABEC/P; hybrid Si₃N₄ balls; high-grade seals/labyrinths); material pairings (e.g., steel/DLC instead of steel/steel) to avoid adhesive wear.
