　　據(jù)報(bào)道，這艘名為Vindskip的貨輪以船身為帆，靠風(fēng)推動(dòng)，不需使用燃油，十分環(huán)保節(jié)能。這艘船體形狀十分特殊，在適當(dāng)?shù)膹?qiáng)度和角度，船體可以作為風(fēng)帆從海風(fēng)中獲得動(dòng)力持續(xù)前進(jìn)。

　　在船身前進(jìn)角度接近逆風(fēng)的情況下，風(fēng)可以產(chǎn)生在船前進(jìn)方向上的推動(dòng)力。由于船體的形狀像一個(gè)對(duì)稱(chēng)的空氣箔片，傾斜風(fēng)穿過(guò)船身必須行進(jìn)更長(zhǎng)的距離，這會(huì)導(dǎo)致真空，拉動(dòng)船前進(jìn)。除了風(fēng)能驅(qū)動(dòng)以外，這艘貨輪采用液化天然氣發(fā)電機(jī)來(lái)補(bǔ)充剩余的能量需求。
