UNDERWATER TECHNOLOGY

On land, GPS helps cars and phones pinpoint their location in seconds. But underwater, these signals vanish almost instantly. Saltwater blocks satellite waves because seawater conducts electricity, absorbing the radio frequencies GPS relies on. Even advanced systems like GLONASS and BeiDou face the

In the world of renewable energy, a Dutch company has made a big step forward. They've just finished testing a new underwater device that turns wave energy into electricity. This isn't just any device—it's a point absorber, which means it can catch wave movements from all sides. The best part? It's
