How can water be used to generate electricity at home?

How can water be used to generate electricity at home? A new turbine uses running tap water to generate electricity at home. Vortical Tech LLC launched the first prototype of their turbine, which generates electricity whenever tap water is used. The hybrid Tesla turbine converts kinetic energy produced by the flow of water into electricity. […]

Why diffusion is faster in water?

Why diffusion is faster in water? This is because in hot water, the water molecules have more energy and are moving faster than the molecules of cold water. Because diffusion happens from high concentration to low concentration, the more molecules are moving, the more opportunities they have to mix together. What is the slowest diffusing […]
