On Saturday I visited a Malawian NGO called Baobab Health. They work to automate the process of caring for patients in the Malawian health care system. My friends Mike, Peter and Soyapi work there.
Here, Peter is showing me a stronger motor from a treadmill that I could drive with my windmill. It outputs 48V, 4x the power of my current windmill. He demonstrates the output using an electric drill to turn the motor. I measure the power with a voltmeter. It's the first time I have used a voltmeter and I think it is very cool. Mike and Peter gave me the motor and the voltmeter as a gift. I am very happy.
