Solar Steam machine

This project demonstrates that it is possible to use the heat of the sun to produce a movement.   The technical principle consists of boiling a liquid (e.g. water) in a closed tank using solar energy. To obtain a temperature sufficient to boil water, parabolic mirrors are used to focus the sun's rays ... »

Water rocket

This water rocket project shows how you can stock energy and illustrates the action-reaction principle.   With the help of a bicycle pump, air is compressed in a tank (bottle) containing some water. By releasing the air, the water is expelled and the rocket is launched high in the air. To optimize ... »
