One of them, an electrical power generated by thermal difference of a ocean water (EPTD) has been exploited for practical use. The EPTD is generated by expansion of liquefied ammonia, but an electrical power produced by water vapor (EPWV) is generated by thermal expansion of water vapor. However, the EPTD system has an extra equipment for liquefaction of ammonia, comparing with the EPWV system, because an ammonia of b.p. -33.5℃ can not be liquefied only by cooling the ammonia gas which is vaporized from the liquid ammonia, using the bottom water (～4.5℃) of deep ocean. The thermodynamics says that a thermal engine can not obtain 100% efficiency with every efforts, since a thermal engine needs the pseudo loss energy, which is, for example, the energy for resetting the piston to the top of cylinder, which is not changed to a work, but is indispensable to a thermal engine. Even the Carnot engine which is free from energy losses, the efficiency μ = (Q1-Q2) / (Q1+Q1'+Q2+Q2') is calculated to be 50% at T2 = O°K, due to the pseudo loss energy, Q2 and Q2'. The thermodynamical calculation of the thermal energy which is necessary for obtaining some electrical energy shows that the ratio of the thermal energy for the EPWV system to that for the EPTD system for the same generation powerr is 1 : 2. It means that the EPTD system wastes more fossil fuels than the utilized perennial natural energy. The water cell, whose electrodes of Cu and Zn are immersed in water shows the same potentials as that of Voltaic cell. When a cell Pt | H2O | H | Pt is used as pH=-meter, the voltage of O.41V is measured and pH=7 is calculated from pH=ΔE/0.059. This shows that a pH-meter also is a kind of water call. Anyaway, a water call is very hopeful as perennial energy source, since we can use a water instead of electrolytes, and it is theoretically possible for us to get the voltage of ca. 4V.","subitem_description_type":"Abstract"}]},"item_3_description_64":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"長崎大学教育学部教科教育学研究報告, 15, pp.17-28; 1990","subitem_description_type":"Other"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"38255","nameIdentifierScheme":"WEKO"}],"names":[{"name":"浜田, 圭之助"}]},{"nameIdentifiers":[{"nameIdentifier":"38256","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Hamada, Keinosuke"}]},{"nameIdentifiers":[{"nameIdentifier":"38257","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Morishita, Hirofumi"}]}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長崎大学教育学部"}]},"item_3_relation_29":{"attribute_name":"論文ID（NAID）","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"40004337865","subitem_relation_type_select":"NAID"}}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00178258","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03882810","subitem_source_identifier_type":"ISSN"}]},"item_3_text_62":{"attribute_name":"sortkey","attribute_value_mlt":[{"subitem_text_value":"03"}]},"item_3_text_63":{"attribute_name":"出版者別言語","attribute_value_mlt":[{"subitem_text_value":"Faculty of Education, Nagasaki University"}]},"item_3_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"濱田, 圭之助"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"森下, 浩史"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-22"}],"displaytype":"detail","filename":"kyoikuKK00_15_03.pdf","filesize":[{"value":"914.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"kyoikuKK00_15_03.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/9477/files/kyoikuKK00_15_03.pdf"},"version_id":"4e526dd0-e1d4-4476-a995-21a59318c3e1"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"不枯渇エネルギーの利用とその理論的考察 ―海洋温度差発電および水電池―","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"不枯渇エネルギーの利用とその理論的考察 ―海洋温度差発電および水電池―"}]},"item_type_id":"3","owner":"2","path":["698"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-12-21"},"publish_date":"2012-12-21","publish_status":"0","recid":"9477","relation_version_is_last":true,"title":["不枯渇エネルギーの利用とその理論的考察 ―海洋温度差発電および水電池―"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T01:45:04.187534+00:00"}
