Outline of Final Research Achievements

In this study, an improved power generation system using a rocket stove and a water heater were developed for use in times of disaster. Both systems are portable and can be moved in times of disaster. The Stirling engine power generation system was capable of strong combustion by using an incinerator that was designed and fabricated. However, although initial power generation was confirmed, continuous power supply was difficult.
The hot water system used a copper tube with a diameter of 8 mm and a total length of 140 cm, which enabled stable combustion and hot water production, as well as steam production by increasing the water flow rate to 1.0 L/min. In addition, a movable LED streetlight using a charcoal accumulator was also produced, and these were shown to the public at classes and other events to raise awareness of disaster prevention.

Academic Significance and Societal Importance of the Research Achievements

ロケットストーブは簡単に製作できるため、東日本大震災でも使用され、その活用方法は注目されている。災害時には、電気や水だけでなく、シャワー利用できる温水も必要であり、本研究はそれら解決を目指したものである。
発電機にはまだまだ課題点が残るが、スターリングエンジンを用いた可搬式の発電機は、これまでなく、外部機関の評価は高かった。また、温水器は、水蒸気までつくることで、蒸留水の獲得も可能で、避難所での活用だけでなく、発展途上国での簡易かつ低コストで安全な水の確保もできる画期的なシステムである。
