Scientists have figured out how to pump water upwards in a thick tube using a combination of surface tension and water-repellent materials. Before you get your hopes up, it's definitely no ...

Designing a gravity rain barrel pressure pump doesn’t have to be difficult to be functional. One of the most overlooked aspects of using collected rainwater is the amount of water pressure it ...

When the region needs water, water pumps utilize the pull of gravity to provide high water pressure. Because they work with gravity, they have to be taller than the buildings they’re providing ...

As the waves continue to pump, they can drive radiation in the universe to extremely high energies, causing the spontaneous appearance of photons: gravity generating light itself. The researchers ...
