VIEW FINDER A PASTIME TO TAP POWER This giant kite can generate 100 mw of energy, sufficient to light 10,000 homes. Scientists from Delft University of Technology, the Netherlands, designed this 1,000-ha multiple kites, called Laddermill. It taps the high-altitude wind, where winds carry a hundred times more energy than on the ground, and

Orlando Wagner and Jochen Hauff compare the booming renewables market with other sectors where a boom has been followed by a bust, on the lookout for danger signals.
