[1] We examine the characteristics of the initial stage (IS) in object-initiated lightning derived from current measurements on the Gaisberg tower (100 m, Austria), the Peissenberg tower (160 m, Germany), and the Fukui chimney (200 m, Japan) and their counterparts in rocket-triggered lightning in Florida. All lightning events analyzed here effectively transported negative charge to ground. For ...

Solar chimneys are attractive because they contribute increasing efficiency in air conditioning processes dwellings and buildings, therefore also aid reduction greenhouse gas emissions. A wide number works dealing with (a...
