Nuna - coming soon to a town near you
November 08, 2002After crossing Australia in record-breaking time to win the World Solar Challenger, Nuna is now touring Europe. The tour, which commenced in Stockholm, will take Nuna to 35 cities in 12 European countries.
Nuna, in its special trailer complete with audio and video equipment, will be on display in schools or museums from 8.30 in the morning until 5 in the evening. Accompanying the car on its travels are two members of the Dutch Alpha Centauri team. As they are the ones who designed and built the car - and drove it to success in the challenge - they will be able to explain to visitors the car's design and the use made of space technology and solar energy.
ESA supplied the Alpha-Centauri team with technology first designed for use in space through its Technology Transfer Programme. Material used included space-age plastic designed for satellites to keep the body light and strong, a new kind of solar cell that will have its first test in space in early 2003, and maximum power point trackers to guarantee an optimal balance between power from the battery and solar cells, even when the sun is hidden by clouds.
Last but not least Nuna had a small strip of solar cells on the side of the car to power the communication equipment. These were rather special solar cells as they were originally used on the NASA/ESA Hubble Space Telescope and brought back from space by ESA astronaut Claude Nicollier in 1993.
The hard work and dedication of the Dutch students, plus a little help from ESA and Dutch sponsors, ensured that Nuna not only came first in the race but also broke records. Nuna's average speed of 91 km/hour set a new record as did the total time taken to cover the 3010 km - just 32 hours 39 minutes.
The Nuna tour has been organised by ESA, to interest the young and not so young in science, space and technology; to demonstrate how space technology can benefit our daily lives and to illustrate the benefits of using renewable energy sources.

Solar Cells News and Current Solar Cells Events RSSPolymer electric storage, flexible and adaptable
The proliferation of solar, wind and even tidal electric generation and the rapid emergence of hybrid electric automobiles demands flexible and reliable methods of high-capacity electrical storage. Now a team of Penn State materials scientists is developing ferroelectric polymer-based capacitors that can deliver power more rapidly and are much lighter than conventional batteries.
Flexible nanoantenna arrays capture abundant solar energy
Researchers have devised an inexpensive way to produce plastic sheets containing billions of nanoantennas that collect heat energy generated by the sun and other sources. The technology, developed at the U.S. Department of Energy's Idaho National Laboratory, is the first step toward a solar energy collector that could be mass-produced on flexible materials.
'Nanonet' circuits closer to making flexible electronics reality
Researchers have overcome a major obstacle in producing transistors from networks of carbon nanotubes, a technology that could make it possible to print circuits on plastic sheets for applications including flexible displays and an electronic skin to cover an entire aircraft to monitor crack formation.
A Colorful Approach to Solar Energy
Revisiting a once-abandoned technique, engineers at the Massachusetts Institute of Technology (MIT) have successfully created a sophisticated, yet affordable, method to turn ordinary glass into a high-tech solar concentrator.
Research helps understand factors that influence efficiency of organic-based devices
Organic-based devices, such as organic light-emitting diodes, require a transparent conductive layer with a high work function, meaning it promotes injection of electron holes into an organic layer to produce more light.
Visualizing atomic-scale acoustic wavesin nanostructures
Acoustic waves play many everyday roles - from communication between people to ultrasound imaging. Now the highest frequency acoustic waves in materials, with nearly atomic-scale wavelengths, promise to be useful probes of nanostructures such as LED lights.
New efficiency benchmark for dye-sensitized solar cells
In a paper published online June 29 in the journal Nature Materials, EPFL professor Michael Graetzel, Shaik Zakeeruddin and colleagues from the Changchun Institute of Applied Chemistry at the Chinese Academy of Sciences have achieved a record light conversion efficiency of 8.2% in solvent-free dye-sensitized solar cells.
Perfecting a solar cell by adding imperfections
Nanotechnology is paving the way toward improved solar cells. New research shows that a film of carbon nanotubes may be able to replace two of the layers normally used in a solar cell, with improved performance at a lower cost. Researchers have found a surprising way to give the nanotubes the properties they need: add defects.
Testing, radiation testing: Northwestern transistors on space station
Transistors based on a new kind of material created by Northwestern University researchers have been lifted into outer space on the space shuttle Endeavour and attached to the outside of the International Space Station for radiation testing.
Researchers demonstrate 'avalanche effect' in solar cells
Researchers at TU Delft and the FOM Foundation for Fundamental Research on Matter have found irrefutable proof that the so-called avalanche effect by electrons occurs in specific, very small semiconducting crystals.
