A vehicle (400) such as an aircraft is provided (101) with a source of light (401). An optical conduit is then used to couple (104) this source of light to a light-to-electricity conversion apparatus (408). which then converts (105) such light into electricity. A rechargeable power supply (407), such as a battery, uses (106) at least part of the electrical power output of the light-to-electricity conversion apparatus to be charged. |
