Featured Experiment: Harvesting Wind from Moving Vehicles

Experimental Methodology and Design

A team at Sebelas Maret University conducted a fascinating experiment to quantify the potential of harvesting wind energy from moving vehicles 2 .

The researchers installed mini horizontal wind turbines on a vehicle to capture the relative airflow generated during movement. As a vehicle moves, it creates airflow containing kinetic energy that can be harnessed through strategically placed turbines.

Experimental Setup
  • A mini-wind turbine system was mounted on a moving vehicle
  • Connected to a generator that converted rotational energy into electricity
  • Tests conducted at speeds ranging from 20 to 100 km/h
  • Data analyzed using Python-based regression modeling

Experimental Results

Vehicle Speed (km/h) Generated Power (W) Efficiency (%)
20 0.46 74.2
40 2.09 84.3
60 5.80 96.8
80 12.68 127.8*
100 24.46 157.8*

*Efficiency values exceeding 100% likely indicate measurement limitations or additional factors contributing to energy generation 2 .
