I present two inventions can solve at least in part the water problem.
Personally I love both of the them, because my country have enough
water ( we have a lot of Reservations of underground water and many rivers with sweet water), the problem is the contamination and the distribution of it.
1) System of water pumping with a bicycle - A great Idea!!
A Rotary Club in Zaragoza Spain developed a System of water pumping with a bicycle, the three properties were there it can function with almost without effort, with a little maintain and low cost. The inventions allows pump 500 lts. of water by hour. This invention could help developing countries in agriculture and another areas.
You can read about it in the next link.

2) Water system with pedal (I love this one, I probably make it my Act4 - Will see)
The winning Aquaduct Mobile Filtration vehicle was designed to help
people living in developing countries, who often do not have access to clean water. The Aquaduct vehicle transports water and cleans it while
in motion. Many women in developing countries need to walk great distances in order to bring water to their families. The new vehicle offers an easier way to cover these distances, and is intended to reducethe pollution caused by motorbikes or trucks used for water transportation.
