Earlier this month, Beena Sukumaran, a professor at Rowan University, and a number of students have developed a pedal-powered grain crusher. This is an entrepreneurial version of the successful Doctors Without Borders and Engineers Without Borders models.
The aluminum grain crusher can be attached to any bike mounted on a stand. When a rider begins to pedal, the back wheel turns a pulley that moves plates in the crusher that process grains until they're suitable for cooking.
Their aim was to create a device for people in developing countries to use to process various grains for cheap. Furthermore, it could also help generate income for people traveling from village to village.
