Solar electric motor
This project helps to understand how an electric motor works (how it is possible to create a movement with electricity). Many electrical appliances use this technique (mixer, cd player, hair dryer, etc.).
By generating electricity from the Sun, this DIY shows that there are alternative energy sources to produce electricity which are renewable and environmentally friendly.
The use of photovoltaic cells to power electric motors is already used for cars or boats prototypes .
The "reed switch" used in this DIYs project replaces the traditional contact brushes as it reduces friction. With less friction, it is possible to run a very roughly made motor powered by the electricity coming from a small solar cell.
