This paper presents and discusses the results of the first stage of an ongoing research program to improve the design of wave powered navigation aids using the oscillating water column principle. Wave tank testing has shown that the heave motion of current tail tube buoys is the predominant feature of the hydrodynamic response. A Wells self rectifying air turbine, coupled to a 100-W generator which produces an optimum level of damping to the water column for peak performance, has been designed and tested. It has been concluded from preliminary sea trails that a simple, efficient, reliable, turbine-generator has been developed to meet the requirements of the current design of navigation buoy. However there is considerable scope for improving the hydrodynamic design of wave activated buoys.

Mems Technology

As portable devices become smaller and more convenient, they increasingly require miniaturized batteries that preserve the light weight of the device while delivering sufficient power. However, miniaturization of conventional magnetic devices is precluded by the magnetic material and helical structure of the coil. To solve this problem, we introduce a multilayer ceramic technology that realizes three-dimensional miniature magnetic devices. The miniature components are fabricated by micro-electro-mechanical systems (MEMS) technology. This paper describes an electromagnetic motor and an electromagnetic induction type air turbine generator developed through MEMS and multilayer ceramic technologies. The fabricated motor is 4.2 [mm] in diameter and 6.0 [mm] in height, runs at 1080 rpm, and has a consumption power of 0.11 [W]. The air turbine generator is 10.6 [mm] long, 10.6 [mm] wide, and 3.6 [mm] high. Connected to a 4 [Ω] load resistor, its output power is 195 [μVA] at a rotational speed of 9000 rpm.
