Wind turbine with blades made from 160 mm diam PVC pipe. Rotor diam 2m. Housing made from same PVC pipe. Double air-inlets angled in wind direction with outlet at the back for generator cooling. 2-pole power feed allows 360 degrees rotation without cable twisting used swivel-weel with ball bearings. Wind direction blades made of aluminium. Erected on a 3,6 meter tall wooden pole with four metal wire supports. Base attached to concrete block and metal support with two bolts allow one person to handle maintenance. 12V to 220V 50Hz 100W inverter connected for show, but will connect to a deep-cycle lead-acid battery instead. Housing designed for Ametek PM motor, but video shows operation in very slow wind without generator installed. Still working on electronic controls. A PIC microcontroller will handle charge control and switching to a 12V kettle heating element when battery is full. Planning to install wind speed, RPM and current sensors which will be fed to the microcontroller. Communication from micro fed to serial bluetooth modem with 100m range. Datalogging can then be done in-house and in real-time for finding optimal RPM at a certain wind-speed. Feel free to add comments, suggestions and questions.
