For more effective ventilation from the room floor, where polluted air and dust arise, a new ventilation system located on the ceiling has been developed by using fresh intake air and generating a tornadolike vortex to ventilate the air near the floor both locally and directly. In a water tank, which simulated a room space, the same tornadolike vortices were visualized using ink diffused from the base, and the ventilation efficiency was measured. In order to apply this new ventilation system to local cooling, the heat transfer performance at the floor was also investigated.

Technologies for the load-leveling of electricity do not directly contribute to the reduction of CO_2 emission which is now the critical political issue in development in the energy field. Though lowering of the load factor is inevitable from a natural feature and a socio-economic activity of Japan, it is a great social loss, considering the operation time of the large-scaled centralized power stations. In this development, we aim at the preparing the technical alternative for the load-leveling and pioneering the new field for hydrogen energy uses in the near future. Here we describe the test fabrication of an reversible cell with enlarged-electrode area to prospect to the technical feasibility of kW-class cell stack and the system integration among a water electrolysis, a hydrogen storage and a fuel cell to optimize both functions of co-generation and energy storage.
