Abstract

Embodiments of a manually-powered communication device such as a cellular mobile telephone, a satellite phone, or a walkie-talkie include a manually operable crank; a dynamo flywheel generator arranged to receive energy input from the manually operable crank; a low wattage power supply, such that the power supply is operably connected to the dynamo flywheel generator and receives energy therefrom; a capacitor with a buffer that comprises a power storage capacity sufficient to operate the mobile telephone without continuous manual input, the capacitor receiving energy from the power supply; a processor operably connected to the capacitor and able to receive energy therefrom; and a modem that is operably connected to the processor and arranged to receive energy therefrom. The crank, the generator, and the capacitor are all included in a power unit portion of the device; the power supply, processor, and modem are included in a main body of the device.
