The smiling sun
Today, NASA’s Solar Dynamics Observatory caught the Sun “smiling.” Seen in ultraviolet light, these dark patches on the Sun are known as coronal holes and are regions where fast solar wind gushes out into space.
The V 22 Osprey is an engineering marvel.
Take off like a helicopter, then change the mode while flying and fly like an airplane…and finally land like a helicopter and fold it back to rest in a corner of the ship…can you imagine such a design? But there is such a plane in this world….its name is V22 Osprey owned by US Defense…..

Clean Energy
The location is the 4,000-acre bottom of dry Ivanpah Lake in California’s Mojave Desert. Three hundred thousand movable mirrors, curved around the three towers, capture energy from the sun, reflect it, and vaporize the water at the top of the tower at temperatures above 500 degrees Celsius. This steam is used to spin the lower…
