Engine powered by solar energy - a toy of a teaching demonstration. Figure
explain the essence and image of the structure. The dimensions are determined owned solar cell (often a single cell can be purchased for so-called. Pennies on the Allegro).
Notes on construction:
- motor efficiency (work on "weak" sun) depends primarily the accuracy of the axle assembly - the socket axis and the balance across the border - useful at this point patience and pinpoint accuracy,
- the beginning and end of the coil, we combine directly with (+) and (-), solar battery,
- glue a magnet to the wooden support "a drop" or resin.
to start the engine needs a setting sun and the manual start.
