| Outline of Final Research Achievements |
A toy called "drinking bird" is a heat engine that continuously repeats swinging motion and a mimicry of drinking motion by evaporation of water. In this study, we estimated the surplus energy of the drinking bird in the swinging motion and developed a recovery device in order to examine the possibility as an energy plant. First, we constructed an experimental system to measure the toy’s motion. Then, we established an estimation method of the surplus energy by analyzing experimental data. Finally, based on those results, we designed and produced a drinking bird about three times as large as commercially supplied drinking birds, but could not obtain the same motion as them. In addition, we devised a generator suitable for the drinking bird and demonstrated its effectiveness by making the principle model of it.
