Purdue wind tunnel key for 'hypersonic vehicles,' future space planes

By using the only wind tunnel capable of running quietly at "hypersonic" speeds, Purdue University engineers have conducted experiments to yield critical data for designing an advanced aircraft called the X-51A, powered by engines called scramjets.

2. Policies key as ethanol 'revolution' links agriculture, energy sectors
   02-15-2008 · EurekAlert!
   The recent boom in production of ethanol from corn grain has tightly linked the agriculture and energy sectors in an unprecedented fashion. Purdue University researchers developed a model, based on a range of possible oil prices, that predicts impacts of federal economic policies on future consumer and government costs, ethanol production and many other aspects of the two sectors.

5. Astrophysicists find fractal image of Sun's "storm season" imprinted on solar wind
   05-25-2007 · EurekAlert!
   Plasma astrophysicists at the University of Warwick have found that key information about the Sun's "storm season" is being broadcast across the solar system in a fractal snapshot imprinted in the solar wind. This research opens up new ways of looking at both space weather and the unstable behaviour that affects the operation of fusion powered power plants.

7. Pellets of power designed to deliver hydrogen for tomorrow's vehicles
   08-21-2007 · EurekAlert!
   Hydrogen may prove to be the fuel of the future in powering the efficient, eco-friendly fuel cell vehicles of tomorrow. Developing a method to safely store, dispense and easily "refuel" the vehicle's storage material with hydrogen has baffled researchers for years. However, a new and attractive storage medium being developed by Pacific Northwest National Laboratory scientists may provide the"power of pellets" to fuel future transportation needs.

8. Photo favourite: ATV rendezvous simulation
   11-13-2006 · European Space Agency (ESA)
   A choice from our ESA photo galleries
   
   Tests conducted at Val de Reuil, France, to simulate the rendezvous of the Automated Transfer Vehicle (ATV) with the International Space Station (ISS). Sensors mounted on an articulated industrial robotic arm (image) acted as the ATV, whilst a 120-tonne mobile platform represented the ISS. During simulations the platform was made to approach the robotic arm in a motion identical to the one expected when the real vehicles rendezvous in space next year.
