  • “If we don’t change direction soon, we’ll end up where we’re heading” There are few signs that the urgently needed change in direction in global energy trends is underway. Although the recovery in the world economy since 2009 has been uneven, and future economic prospects remain uncertain, global primary energy demand rebounded by a remarkable 5% in 2010, pushingRonald Wennersten/Industrial Ecology/KTH to a new high.

  • First flight of the Wright Flyer I, 17 December1903, Orville piloting, Wilbur running atwingtip. The distance over the ground was measured to be 852 feet (260 m); the time of the flight was 59 seconds. Ronald Wennersten/Industrial Ecology/KTH
  • What on earth can this be used for?Ronald Wennersten/Industrial Ecology/KTH
  • Who would have imagined this? Airbus A380Provides seating for 525 people in standard three-class configurationor up to 853 people in all economy class configuration Ronald Wennersten/Industrial Ecology/KTH
  • Solar Impulse Ronald Wennersten/Industrial Ecology/KTH www.solarimpulse.com
  • Solar ImpulseAerodynamicsThe wingspan of Solar Impulse is 80 metres, slightly wider than thewingspan of an Airbus A380. The ultra-light structure must usecustomised carbon fibres.EnergyPhotovoltaic cells will generate electricity during the day, which willserve both to propel the plane and to recharge the batteries to allowflight at night.PropulsionThe average power provided to the engines will be on the order of 12hp, comparable to that of the Wright Flyer Ronald Wennersten/Industrial Ecology/KTH
  • What will happen in the next 100 years? Ronald Wennersten/Industrial Ecology/KTH
