POWER EMITTED BY THE SUN

The amount of energy reaching the surface of the Earth every hour is greater than the amount of energy used by the Earth's population over an entire year.

The total power emitted by the sun is calculated by multiplying the emitted power density by the surface area of the sun which gives 9.5 x 10²⁵ W.

 The total power emitted from the sun is composed not of a single wavelength, but is composed of many wavelengths and therefore appears white or yellow to the human eye. These different wavelengths can be seen by passing light through a prism, or water droplets in the case of a rainbow. Different wavelengths show up as different colors, but not all the wavelengths can be seen since some are "invisible" to the human eye.

ARTIFICIAL SNOW MOUNTAIN

Boreal is the site of the first North American demonstration of a relatively new technology called Snow factory. The process parallels that of an industrial icemaker — essentially, a large-scale version of the icemaker in the door of many household refrigerators.

An ice-maker takes water chilled with a heat ex-changer and sprays it onto a surface. The cubes are created by imposing the ice onto a grid. In a unit about the size of a trailer, such as the type pulled by 18-wheeler trucks, Snow-factory uses the same process to produce flat flakes that are collected on a panel and fed into a conveyor belt. The flakes are then blown through a pipe up to 600 feet (183 meters) long to the desired location on the ski slope. [Photos: The 8 Coldest Places on Earth]

ROBOT TABLE TENNIS TUTOR

The robot, called FORPHEUS, was named the "first robot table tennis tutor" for its ability to play and teach the sport.

Table tennis also probably known as Pin Pong got its start in England towards the end of the 19th century when after dinner, some upper-middle class Victorians decided to turn their dinning room tables into miniature versions of the traditional lawn tennis player field. The robot, called FORPHEUS, was named the "first robot table tennis tutor" for its ability to play and teach the sport.
Guinness World Record officials said the robot's "unique technological intelligence and educational capabilities" earned it the title.The record-breaking robot uses vision and motion sensors to track a
match, with cameras following the ball 80 times per second. The robot can project an image of where the ball will land to help a competitor or student. Algorithms and artificial intelligence also allow FORPHEUS to rate players, assessing their gameplay to better tailor the lessons.
