Spindrift Spindrift Spindrift (more rarely spoondrift) usually refers to spray, particularly to the spray blown from cresting waves during a gale. This spray, which "drifts" in the direction of the gale, is one of the characteristics of a wind speed of 8 Beaufort and higher at sea. In Great Britain "spindrift" is the telltale sign used by mariners to define a Force 8 (Beaufort Scale) wind (not higher) when observed at sea. See this example of information provided by Lymington Harbour authority, Hampshire, England, UK, explaining the whole scale, the associated wind speeds, and its telltale signs. Text from the site
Wind lens Wind lens The wind lens is a modification on the wind turbine created by Professor Ohya from the Kyushu University as an attempt to be more efficient in production of electricity and less invasive to both humans and nature. While still in progress, the wind lens has a few changes in design which have led to impacts on how wind energy can be used and harnessed while changing how it impacts the world around us. As the normal wind turbine does, the wind lens harnesses the energy of the wind but has a few modifications in order to increase efficiency
