Hi everyone. I'm trying to help my son with his 7th grade science project. We are testing a model of a geothermal power plant. Basically we will use steam to spin a turbine connected to a motor to make electricity. We would like to connect the motor to some kind of charging circuit connected to an 18650 and then connect that to a USB port to charge a phone just to show a useful application. We can do whatever soldering we need to but I'm not sure of the pieces we will need to charge the battery and output via USB. Any help will be much appreciated.
