Regenerative braking requires a motor-generator on the drivetrain and only activates during braking. RPHS deploys proprietary harvesting units to any rotating mass regardless of whether it's mechanically connected to the propulsion system — and harvests energy from their continuous rotation, not just deceleration events. Every non-driven axle, every trailer wheel, every spinning shaft is a generator waiting to be activated.
Continuous Rotation Harvesting: Energy captured from spinning masses during normal operation — axles turning at highway speed, trailer wheels rolling under load, industrial shafts spinning through full shifts. Deceleration Recovery: Additional energy captured during every braking event, speed reduction, and direction change. Together, these modes harvest energy across the entire duty cycle — not just the fraction of time spent braking.
Unlike solar, RPHS harvests energy whenever something spins. Night, clouds, tunnels, underground mines — irrelevant. If the wheels are turning or the shaft is rotating, energy is being harvested.

Non-driven axles, trailer wheels, industrial shafts, and free-spinning components carry rotational kinetic energy every second they spin. RPHS harvests a fraction of that energy continuously during normal operation. On a highway semi, trailer axles spin at 500–800 RPM for hours without interruption. That is energy available for harvest across the entire drive — not dependent on braking events.
During braking, speed reduction, and direction changes, rotating masses shed kinetic energy rapidly. RPHS captures this burst energy in addition to continuous harvesting. A garbage truck braking 200+ times per day generates massive deceleration energy — but between those stops, the axles are still spinning and still harvestable.

Harvested energy stored onboard can be exported to the grid during peak demand periods when electricity prices are highest. A fleet of 50 garbage trucks harvesting 18,000+ kWh each doesn't just reduce fuel costs — it sells power back. The vehicle becomes a rolling power plant.
Individual vehicles contribute small amounts. Aggregated across a fleet — hundreds or thousands of vehicles — those contributions become utility-scale power. A municipal fleet becomes a virtual power plant without building a single solar panel or wind turbine. The energy comes from motion that already exists.
Grid operators pay for fast-response power injection to maintain 60 Hz stability. RPHS-equipped fleets can participate in ancillary services markets — getting paid to stabilize the grid with energy that was otherwise wasted.
Fleets returning to depot during evening peak hours can discharge harvested energy, reducing the facility's peak demand charges. Demand charges can represent 30–50% of a commercial electricity bill. RPHS cuts that directly.
When the grid issues demand response signals, RPHS-equipped vehicles can export stored energy or reduce their own draw. Fleet operators get paid for participation. The grid gets relief. The energy comes from wheels that were already spinning.
