TU Delft students want to win largest solar-car raceA team of TU Delft students from various faculties, named The TU Delft Alpha Centauri Team, is working on a car that is powered only by solar energy.
They hope to join the world solar challenge 2001, in Australia. Some five hundred teams will compete in this 3010km race. TU Delft’s executive board has been asked to sponsor the project. Teachers at TU Delft give the students technical advice. Besides wanting to win the race, the TU Delft team also plans to promote vehicles driven by sustainable energy in lectures and at conferences.
Food can be preserved by an electric field
A strong, pulsing electric field can kill micro-organisms in food, thus slowing decay, according to Sjoerd de Haan of the ITS departement of Electrical Power Processing. The main advantage is that the food is less effected. Traditionally, milk, for example, is heated up to 140°C. This heating also consumes lots of energy and cleaning products, which are necessary for cleaning the heating elements that get burned slowly.Researchers at TU Delft, the Dutch research institutes ATO and TNO, and the milk company Coberco, are now trying to find out whether it’s possible to kill all the micro-organism and also to deactivate all the spores of those microbes using a pulsed electric field. The experimental setting that’ll be built in Delft uses one gigawatt of power. “That sounds strange when you want to save energy. However, the pulses are very short and therefore the energy use is quite low.” The researchers in Delft will look for the lowest pulse that is required for the desired effect.
