low voltage output

Hi, I'm trying to get a small dc motor to run for the longest possible time from the energy of a small solar panel with a liion battery (or cap). The solar panel output up to 40mA at 0.5v (close to max max power point). I have tested the motor, it starts at 0.142v/11mA (I can also do 24mA and...
