Abstract
Power is provided to a remote device by receiving external energy from a laser source and storing the energy in a storage battery. A photovoltaic receiver capable of alignment in a preferred reception direction for receiving energy is used to receive energy from a source of excitement energy, and is configured to receive energy from a laser which is directed to the photovoltaic receiver. A charging circuit receives power from the photovoltaic receiver and is used to charge the storage battery.
