Power+ / Energy


At least 300,000 people in Africa use rollers to carry water more easily now, but they still face the
problems of power shortage, so we propose a simple but very meaningful concept: add the power
storage device in the water roller, When people have got enough water walking a long distance by
water roller, power+ stores enough electric power for night lighting, mosquito repelling, phone charging, ect. Power+ is made of PE plastic, and the shape of the handle is more convenient for people use. Power+ can ease Africans’ shortage of electricity using, and effectively improves Africans’ living conditions in a way.
