Ozone vacuum-ultraviolet (VUV) ozone generators, employ a light source that generates a narrow-band ultraviolet light, a subset of that produced by the Sun. The Sun's UV sustains the ozone layer in the stratosphere of Earth. UV ozone generators use ambient air for ozone production, no air prep systems are used (air dryer or oxygen concentrator), therefore these generators tend to be less expensive. However UV ozone generators usually produce ozone with a concentration of about 0.5% or lower which limits the potential ozone production rate. Another disadvantage of this method is that it requires the ambient air (oxygen) to be exposed
Pursuit of the Sun & Allure of the Earth Pursuit of the Sun & Allure of the Earth Pursuit of the Sun & Allure of the Earth is the first full-length album by the Canadian black metal band Woods of Ypres. It was recorded in 2004 at Spectre Sound in Tecumseh, Ontario. This marked Woods of Ypres' first release with David Gold on vocals and guitar as well as drums, along with the first appearance of keyboardist Jessica Rose. Steve Jones & Connor Sharpe supplied most of the lead guitar and bass work for this album, but were uncredited in the album booklet due to leaving Woods of Ypres
