The vibrating mass may be mounted within an aperture in the ground and secured in place using concrete to increase the vibration-transmitting characteristics of the vibrating mass. An electrical system including a source of electricity and a storage device, as well as controls, is mounted separate from the source of vibration and the vibrating mass (e.g., the concrete culvert) to isolate portions of the electrical system (including the storage device) from some of the effects of the vibration. | 06-26-2014 |
