Bicycle Powered Mobile Phone Center

Llamadassa has put together a Bicycle Powered Mobile Phone Center. The idea is great since it doesn’t require AC power, transporting the phone center charges the battery and the battery can also be charged while the unit is stationary by lifting the wheel off the ground.

“The one essential thing that a cell phone has that a call shop doesn’t is a battery, so using parts found in a junk yard we created a constantly recharging battery by pedal power. Electricity is generated as the person is traveling to his destination, if the battery runs low at the destination he can drop the kick stand and start cycling in place. Generating electricity from pedaling allows us to travel to the central park, a remote town or a big festival increasing access to inexpensive telephony anywhere.

Because this bike is built for the developing world we had to use parts that could be easily found. To generate the electricity we used an old car alternator that sends the electricity generated to a car battery. The electricity stored in the battery is accessed by an old computer UPS to convert the electricity to 110V.”
