Kenyan students charge cellphones with pedal powerThis DIY gadget is dubbed the “smart charger” and it’s from two Kenyan students who reside in rural areas without electricity. They also use bikes to get around. Jeremiah Murimi and Pascal Katana use a dynamo attached to the bicycle in order to charge cellphone batteries. The whole process costs practically nothing.

They used parts from old discarded radio and television sets to assemble the small charger. The user is able to plug the dynamo lead right into the device. An hour of pedaling can fully recharge the battery in about the same time it would take if it was plugged into an electrical outlet. The idea is that the user would avoid paying $2 each time for battery recharges by making a one-time smart charger purchase worth about $4.50.
