BMW Group installed an Aeromine rooftop wind system at its MINI Oxford Plant as a pilot announced on 4 September 2024. BMW said the trial would assess the technology’s potential at its sites and other UK commercial buildings. The announcement described how the system works, but reported no measured output or trial results.
What BMW installed at the Oxford plant
BMW called the installation the UK’s first “motionless” wind energy system. It was designed by Aeromine Technologies and placed on the roof of the Oxford Plant, where MINI vehicles are manufactured. BMW presented the site as a testbed for assessing the system’s potential to improve energy efficiency at BMW locations and commercial buildings in the UK. BMW Group’s 4 September 2024 announcement does not give a measured generation figure for the Oxford unit.
How Aeromine’s “motionless” system works
BMW says the unit is installed at a building edge and oriented toward the prevailing wind. Its vertical, wing-like airfoils create a vacuum effect that draws air behind an internal propeller, which generates electricity.
“Motionless” refers to the unit having no visible moving parts. It does not mean there is no moving component: BMW’s description includes an internal propeller. BMW says the design is intended to minimise noise and vibration and have a low impact on wildlife, but its announcement provides no independent measurements of those effects.
#1 Best Overall
- 【VERTICAL WIND TURBINE】The blade material is synthetically injection molded with high-strength FRP material. At the same time, the fashionable The spiral blades are aerodynamically designed to make the rotor run smoothly and reliably, which leads to stable electricity generation. The wind turbine can start from the breeze and adapt to the wind 360°, no yaw system is needed.
- 【LONG SERVICE LIFE】Maglev generator provides lower start torque/wind speed and longer service life.Design service life 10~15 years. Maximum RPM protection. No higher than 300RPM, regardless of the wind speed.
- 【EXCELLENT PERFORMANCE】Designed with three-phase AC PMG, it boasts low torque, high-power tracking intelligent microprocessor that can effectively regulating the current and voltage. It obviously increases wind energy utilization and annual power generation.
- 【LOW NOISE】 Drawing on the design principle of aircraft wings and the horizontal plane rotation, noise can be reduced to a level that cannot be measured in the natural environment. Due to its compact shape, low starting wind speed, and large windward area, the wind turbine can generate electricity at lower wind speeds.
- 【MULTIFUNCTIONAL USE】Vertical wind turbine is easy to install. Vertical wind turbines can easily adapt to various environments.It is ideally suited for boats, gazebos, cabins or mobile homes, as well as for green windmills, home, corporate and industrial energy supplem.
What the stated size and building uses mean
BMW describes typical Aeromine installations as 50 kW or larger and lists large, flat-roof buildings—including warehouses, big-box retailers, data centres, offices and apartment buildings—as intended settings. These are descriptions of the technology’s typical scale and target applications, not confirmation that the Oxford installation produced 50 kW or that every building in those categories is suitable.
How it fits with solar at MINI Oxford
BMW says the wind pilot is intended to complement solar arrays already at the plant. According to BMW’s MINI Plant Oxford page, the Body Shop solar installation has more than 11,000 panels and generates enough electricity to power the equivalent of 850 households for a year. Those figures describe the plant’s solar installation, not the wind pilot’s output.

Assessing how rooftop wind and solar work together would require information such as generation over time and in different weather, roof space, installation and maintenance needs, noise and vibration, wildlife effects, and integration with storage. BMW’s announcement provides no comparative performance data on those factors, so it does not establish that the pilot outperforms solar—or the reverse.
What the pilot has—and has not—shown
The announcement establishes that BMW installed the system and intended to evaluate its potential. It does not state measured electricity generation, how long the trial would run, whether the unit is still operating, or whether BMW chose to deploy it elsewhere. The 50 kW figure is BMW’s description of typical system installations; it is not a reported result for Oxford.
