servatius here develop the technology and scale it up to rival today's wind turbines.we're starting small and have a long way to go while always starting over. for now the kite is attached by cable to a telescope a car mounted on a truck when fully deployed it should soar high in the sky trials are conducted at an airfield in the country saucily but the team is based in berlin. and. the big challenge right now. he's programming the computer to steer the kite with cables like these. the generator that produces the electricity is in this truck. in off grid locations the dirty diesel generators are often used in are quite technology could replace them. today's wind turbines are mounted on towers the kites tethered to lines would rise to a height of two or three hundred metres where the wind is stronger and more persistent than closer to the ground. the intercut laboratory is on a campus of the technical university of berlin the engineers started experimenting seven years ago with fabric kites. when the kite goes up the lines on furrow and turn a turbine which generates el
