Darwin200 Episode 18: Wind turbine project

The young scientists design, create and test their own mini-wind turbines to discover which blade shapes and sizes generate the highest voltage output!

Five teams of young scientists created very varied designs using nothing more than craft items and equipment found on the Darwin200 ship!

Some of the finished entries resembled real wind turbines, which we have observed at wind farms during our UK voyage, while others were somewhat unconventional.

The finished mini wind turbines were tested by me, equipped with a hair drier to create artificial wind, a toy electric motor run as dynamo and a voltmeter to determine the output generated.

The results surprised everyone, and goes to show that biggest is not necessarily best!
