100-year-old Tesla invention is useful in ways we hadn’t realised, scientists say

A 100-year-old Tesla invention is actually useful in ways scientists had not realised, according to new research.

Nikolas Tesla won a patent for the device he created in 1920, one of many breakthrough inventions created by the engineer and futurist.

But more than a century on, scientists have found that the “Tesla Valve” is not only more useful than previously realised, but that it could have other entirely new applications.
