Parasitic Power Pack (P3)

Parasitic Power Pack (P3) is a modular power generation device that will fit into a 3-inch diameter free floating buoy on the ocean surface. P3 will not interfere with the antenna on the upper portion of the buoy and will not occupy more than 20 inches in length producing a steady power output of at least 4 milliwatts with a capacity to store at least 60 joules of energy. Of the different energy harvesting concepts for powering wireless sensors we use the incessant oscillations of the ocean waves under which the buoy is excited. Unlike regular wave energy devices that are tuned to ocean waves, we have a platform whose dimensions are preset for a specific purpose. Our intent in this effort is to design this platform which is not tethered to the ocean bottom, but a robust maintenance free design that can survive the shock loads that will be imposed on delivery and one that will survive other operating conditions that it could be subjected to. We will demonstrate the effectiveness of our technology through mechanical and electrical modeling.
