airflow for the testing of small wind rotors.

Current system is insufficient & inadequate. Consists of:

Lego Generator & LEDs to measure power output.

The channel tube is a box shape made out of scrap material.

ProblemDesign & build a wind rotor testing system. Capable of testing wind rotors up to 30 cm in

diameter. Automated, so the user can obtain

measurements of rotor power output to wind speed.
