Energy
in motion.

A moving vehicle already generates a continuous air flow. Today that flow is treated as nothing but drag.

The GEAC — Kinetic-Coupling Wind Generator — is MARHON's architecture for converting part of it into electricity the vehicle can use.

01 / The problem

The electric vehicle
spends energy
while it moves.

And motion itself — the one thing never missing during operation — remains almost entirely unused as a source of onboard generation.

Range
Range stays bounded by battery capacity and by the energy density available today.
Recharging
Operations depend on stops and external infrastructure — the real bottleneck for fleets and mass transit.
Available energy
A continuous air flow surrounds every moving vehicle, and is currently treated only as aerodynamic drag.
02 / The solution

GEAC
Kinetic-coupling
wind generator

A compact, modular architecture designed from the outset for vehicle integration — not a scaled-down conventional turbine. It captures the air flow of travel, converts it into electricity and releases the air through an enlarged outlet, with low aerodynamic penalty.

03 / Markets

Where motion
is constant.

The more hours in motion, the greater the value of onboard generation. That is why the GEAC targets fleets and mass transit before the retail market.

01
Commercial fleets
Logistics, distribution and road freight — high daily mileage and a measurable energy cost per kilometre.
02
Metro and BRT
Continuous operation, fixed routes and predictable speed: the most favourable case for onboard kinetic generation.
03
Marine vessels
Adapted configuration for charging battery banks aboard commercial and support craft.
04
Retail automotive
Private vehicles, first as an installed accessory and later as factory-fitted equipment.
05
Public sector
Municipal and state authorities, transport concessionaires and fleet decarbonisation programmes.
Each market, its own path
Configuration, unit count and commercial model differ by segment.

Business.

MARHON Desenvolvimento de Tecnologia Ltda. is a Brazilian engineering company dedicated to technologies applied to energy and mobility, headquartered in Rio de Janeiro.

The GEAC is its first project. The next stage is physical: build, instrument, measure and validate — without anticipating experimental results.
