There are very few contraptions devised from waste and fewer still, which are embracing owing to their simple functioning and worthiness. After Bicilavadora, the bicycle washing machine and the Bicimolino, the corn grinder, yet another application from waste Bicibomba movil has transformed lives of the people in rural Guatemala.
Bicibomba movil is a bicycle powered water pump worked out by Jon Lear, a Mechanical Engineering student from University of Sheffield along with Guatemalan NGO Maya Pedal. The machine under question is human powered and is attached to the rear of a normal bike in a frame with an old electrical pump converted to a friction drive attached to the back wheel. The back tire of the bike makes direct contact with the former armature of the motor covered with rubber from an old tire to give better grip. Tested to a range of heights and on flat grounds the pump can achieve a flow rate of 40 liters per minute – equal to about three normal showers whereas on flat ground the pump can achieve a flow rate of 5 liters per minute.
Built from disused bicycle parts and other scrap materials Bicibomba movil machine has helped improve the daily lives of Guatemalans, without them having to resort to expensive electrical or environmentally damaging fossil fuelled machines. It has become a regular production there.
