Summary

Story summary

Researchers have developed a method to make aluminum tubes unsinkable by trapping air bubbles inside.
The tubes are about one-fifth of an inch in diameter and can form larger floating structures for energy harvesting from ocean waves.
Chunlei Guo, a professor at the University of Rochester, notes the ocean's potential as a resource.
Andreas Ostendorf, a professor at Ruhr-University Bochum, described the development as "really interesting."
