The Wheel, Reinvented.™ 5,000 years after its invention, the wheel still does one thing: it gets pushed. Two billion vehicles on the road today prove it. ReWheel — the Recovering Energy Wheel — changes that, turning the wheel itself into a self-propelled green engine.
The wheel hasn't fundamentally changed in 5,000 years. It has always BEEN driven by an external engine — human, horse, steam engine, internal combustion engine, EV motor….
NOW, the intelligent Recovering Energy Wheel can at times act as its own engine, transforming energy between kinetic and potential forms, back and forth, and conserving the external energy source — i.e. gasoline, electricity, or any other outside energy source
The significance of ReWheel — the Recovering Energy Wheel — is difficult to overstate, particularly in light of the following three aspects:
(1) The energy savings here are independent of the original energy source — ICE, EV motor, etc.
(2) Being free of limitation of fundamentally different technology of EV regenerative braking:
(a) Battery Charge Limits
(b) Temperature Constraints
(3) The ReWheel can operate across a much broader range of vehicle speeds and driving conditions, making it universally applicable to all vehicle types and powertrains.
ReWheel— the Recovering Energy Wheel — vs. EV Regenerative Braking.
(1) The energy saving by ReWheel is independent of the original energy source — ICE, EV motor, or any other. Therefore, a largest portion of the fleet — those powered by Internal Combustion Engines — which today is not covered by any energy-saving technology, will finally benefit.
(2) Compared to the fundamentally different technology of EV regenerative
braking, which suffers from the following limitations:
(a) Battery Charge Limits: Regenerative braking effectiveness drops when the high-voltage battery is at or near (100%) capacity. The battery management
system (BMS) restricts energy capture to prevent overcharging.
(b) Temperature Constraints:
When the battery is cold-soaked or overheated, its chemical ability to accept a rapid charge decreases, limiting the regenerative force to protect cell health.
(c) Motor - vehicle speed - Limitations:
As vehicle speed approaches zero, the back-EMF voltage drops significantly, causing the regenerative torque to fade. Friction brakes must engage to bring the vehicle to a complete stop.
(3) ReWheel will save energy in
EVs as well, reducing the infrastructure expenditure required for electricity generation
ReWheel Technology Overview
ReWheel captures, stores, and reuses energy directly within the vehicle’s
wheel—without drawing from the existing fuel or electric charge systems.
To decelerate the vehicle, ReWheel converts its kinetic energy (see [1])
into potential energy, storing it inside the ReWheel device (see [2]).
Unlike traditional regenerative braking, which depends on the vehicle’s motor, battery, and drivetrain, ReWheel is a fully self-contained system operating entirely within the wheel. It requires no changes to the vehicle’s powertrain and is more efficient, especially in stop-and-go conditions.
This makes ReWheel a uniquely independent, retrofittable, and universally compatible energy-saving solution.
This makes ReWheel compatible with all vehicle types—whether powered by
internal combustion engines (ICE), electricity, hydrogen, ammonia, or any
future propulsion system.
For ICE vehicles, ReWheel improves city-driving fuel economy by an average of 56%, and by 38% overall, resulting in proportional reductions in carbon emissions.
For EVs, ReWheel complements existing regenerative braking, delivering an
additional 32% energy savings in urban driving, and 22% overall.
Since electricity generation for EVs may still rely on fossil fuels, these energy savings also result in proportional reductions in CO₂ emissions.
Beyond reducing refueling and recharging costs, ReWheel also extends the lifespan of the vehicle’s native braking system, which becomes a secondary, a backup, system.
ReWheel installation is as simple as replacing a wheel. It can be implemented on both new vehicles and the 2+ billion vehicles currently on the road worldwide.
Scientific Basis
[1] Kinetic energy is proportional to a vehicle’s mass and the
square of its speed.
[2] During deceleration, ReWheel converts kinetic energy into stored
potential energy. During acceleration, the process reverses, releasing the
stored energy to assist movement.
ReWheel is based on two core physical principles:
- Inertia — the universal resistance to changes in energy states. This principle enables energy capture within ReWheel.
- Conservation of Energy — energy cannot be created or destroyed, only converted from one form to another.
