Nuna7 nabs World Solar Challenge title in Australia

Filed under: Automobiles,Science,Sustainability by Orangemaster @ 3:30 pm

The Delft University of Technology won its fourth title back in 2007 with its solar powered car Nuna4, but this year with Nuna7 it picked up its fifth title in Adelaide, Australia yesterday.

The Dutch beat their archrivals of Tokai University, Japan who had won the last two editions.

There were obstacles on the way to the finish line: temperatures of almost 50 celsius in the cockpit, taking big chances with specially designed lenses to soak up solar rays, and a grasshopper that bounced around the cockpit.

Solar car from Eindhoven rated street legal

Filed under: Automobiles,Sustainability by Branko Collin @ 10:05 pm

A team of students from the Eindhoven University of Technology has created a solar powered family car that is street legal, Telegraaf reported last Tuesday.

The car called Stella was created by Solar Team Eindhoven in a bid to win the Cruiser Class of the World Solar Challenge in Australia this October. Stella is 4.5 metres long, 1.65 metres wide and seats four. It can go 430 kilometres on a single charge. The solar panel has only got an efficiency rating of 22%. Spokesperson Wouter van Loon told Bright last month that this was a conscious decision: “We could have opted for a space-grade panel, but this way we keep the car affordable.”

The car’s top speed is only 120 km/h because the special low-friction tires cannot handle more. In the past teams of the universities of Twente and Delft also participated in the World Solar Challenge. Delft’s car Nuna, shown here, won the race 4 times out of the 7 it entered, and in 2011 it finished second after Japan’s Tokai Challenger.

soyuz_clogNews from the tech trenches.

– The Nuna 5 solar powered car ran into a ditch last Saturday while preparing for the annual World Solar Challenge, writes Telegraaf (Dutch). The student-built car was driving at a speed of 110 kph at the time. Driver Jelle managed to get out unhurt, but several components of the car, including the solar panel, turned out to be damaged. The team from Delft University expects to have repaired the damage before the October 25 start.

See here for a drag race between Nuna 5 and its predecessor, Nuna 4, during happier times.

The Netherlands has its own space organisation. The NSO (Netherlands Space Office) was kickstarted last Wednesday by Minister Maria van der Hoeven (Economic Affairs) and astronaut André Kuipers. The NSO is supposed to help design and build a Dutch space programme, according to Algemeen Dagblad (Dutch).

Kuipers was recently selected for a half-year stay at the International Space Station starting December 2010.

The Nuna 4 unveiled today

Nuon solar challenge 4

Today in Delft, South Holland (and hopefully with some sun) the unveiling of the Nuna 4 solar-powered car (see the car here) will take place, an event open to all.

The team designed a whole new solar-powered car in order to meet new rules of the World Solar Challenge: less solar cells on the car, the driver needed to be sitting up straight and security measures were tightened. In short, this new car is the first step towards an actual solar-powered car that is more like an ordinary car.

Oh, and the Delft University of Technology is looking for its fourth win in a row.

The Nuna 4 was designed and built by 11 enthousiastic students from the Delft University of Technology, who will be leaving for Australia this summer for the World Solar Challenge, the world championship of solar-powered cars, held from 21 to 28 October.

The unveiling will take place at 16:25 at the field in front of the Delft University of Technology on the Mekelweg for anyone in the neighbourhood.
