1. An apparatus for use in a wellbore, comprising:
- a tubular configured to flow a fluid within the tubular that includes pressure pulses generated by a source thereof; and
an energy conversion device in the tubular, the energy conversion device including an active member configured to generate electrical energy in response to pressure pulses in the fluid, wherein the pressure pulses for generating electrical energy are generated by a modulater that is different from a telemetry modulator, the pressure pulses having at least one of a different frequency and a different amplitude than telemetry pulses.
