1. A method for ensuring available power in a downhole environment, comprising:
- generating acoustic waves;
directing the acoustic waves downhole into a wellbore;
converting the acoustic waves into electrical energy at a downhole location; and
using the electrical energy to provide power to a downhole device.

Abstract
A technique is provided by which energy is physically/mechanically transmitted down through a wellbore. The transmitted energy is directed downhole along a fluid channel and impinges on an energy converter positioned in the wellbore or at another subterranean location. The energy converter converts the physical energy into electrical energy that can be supplied to a downhole device.
