Para-skater uses parafoil to propel himself across a frozen lake in Ohio, demonstrating the power of wind. People have been harnessing the wind for thousands of years for many uses, including transportation, power and recreation. Wind occurs when there is a difference in pressure between two adjacent air masses, with the air flowing from an area of higher to lower pressure. | |
