The air motors, generating 250 kW each, powered a ferry on a predetermined route in Finland. This technology offers a cleaner, quieter, and more cost-effective alternative to conventional marine engines, especially for short-distance operations. The pneumatic system can be integrated into the ferry&#8217;s body, enhancing buoyancy. This innovation promises a sustainable and energy-efficient solution for maritime transport.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers have developed pneumatic propellers powered [&hellip;]<\/p>\n","protected":false},"author":9,"featured_media":6876,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[66],"tags":[],"class_list":["post-6875","post","type-post","status-publish","format-standard","hentry","category-66"],"_links":{"self":[{"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/posts\/6875","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/users\/9"}],"replies":[{"embeddable":true,"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/comments?post=6875"}],"version-history":[{"count":1,"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/posts\/6875\/revisions"}],"predecessor-version":[{"id":6882,"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/posts\/6875\/revisions\/6882"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/media\/6876"}],"wp:attachment":[{"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/media?parent=6875"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/categories?post=6875"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/unescoalfozanprize.org\/zh-hans\/wp-json\/wp\/v2\/tags?post=6875"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
