Title: Hand Water Pump With a Pendulum

Hand water pump with a pendulum - where it is possible to use a little finger for pumping - is very simple solution for pumping water. It provides alleviation of work, because it is enough to move the pendulum occasionally with a little finger to pump the water, instead of large swings. The advantages compared to present hand pump solutions are: less force to start the pump, less water consumption, both arms can be used to fetch the water. It is possible to pump out a 1200 litres of water per hour and both elderly and children can use it.
