A discovery by Australian scientists could potentially open up ways for sea vessels like submarines to go much faster under water.
A team led by a Swinburne University professor showed that drag (resistance) on hot bodies moving through liquid can be drastically reduced by up to 85 percent, potentially doubling their speed.
In practical terms, this finding could help a submarine and other vessels to virtually double their speed while moving under the sea, the journal Physical Review Letters report.
