Manually-powered mobile telephone

A manually-powered 2-way radio communication device comprising:

• a manually operable crank;
• a dynamo flywheel generator arranged to receive energy input from the manually operable crank;
• a low wattage power supply, wherein the power supply is operably connected to the dynamo flywheel generator and receives energy directly therefrom;
• a supercapacitor comprising a power storage sufficient to operate the communication device without continuous manual input, and wherein the supercapacitor receives energy from the power supply;
• a low power-microprocessor operably connected to the supercapacitor and able to receive energy input therefrom, and wherein the microprocessor is sufficiently efficient to operate solely with energy from the supercapacitor;
• and
• a low power radio modem that is operably connected to the microprocessor, and arranged to receive energy therefrom,
• wherein the communication device is able to communicate with a second 2-way radio communication device by way of receiving incoming data from the second device and transmitting outgoing data to the second device, and wherein the incoming data and the outgoing data consist of text message signals.

A method of operating a manually-powered 2-way radio communication device comprising:

• receiving kinetic energy by way of a manually operable crank;
• transferring the kinetic energy from the manually operable crank to a dynamo flywheel generator and rendering into a 3-phase electrical energy;
• transferring the 3-phase electrical energy from the dynamo flywheel generator to a 3-phase AC/DC power supply and rendering it into DC electrical energy;
• transferring the DC electrical energy from the 3-phase AC/DC power supply to a supercapacitor;
• transferring the DC electrical energy from the supercapacitor to a low power microprocessor;
• transferring the DC electrical energy from the low power microprocessor to a low power radio modem;
• and
• operating functions of the communication device by way of the modem.
