One more brilliant invention is to be added to the list of great inventions by teenagers. Hannah Herbst, a bright student at Florida Atlantic University High School, developed an instrument that has the potential to save […]

These plants will use seawater from the oceans’ depths to generate steady amounts of renewable energy and drive massive heat engines. The technology is based […]

There were plants residing on the bottom of the ocean, plants who sway back and forth, as the water moves around them. So, BioPower Systems from Australia thought that making an under-ocean energy collecting system whose movement resembles with the one […]
