Aérophile’s balloon brings breath of fresh air to Paris

09.07.2008
Aérophile of France, a manufacturer of tethered gas balloons, has just launched a unique moored balloon in Paris that provides a source of information on air quality that is visible from over 20km. The balloon is also a tourist attraction that provides excellent views of the city.

The tethered balloon, which is located in the Parc Andre Citroën, in Paris’s 15th arrondissement, uses an innovative lighting system to provide real-time reports on atmospheric pollution.

The balloon displays the quantity of the three most harmful contaminants (nitrogen dioxide, ozone and particles) found in the atmosphere, using an easy-to-understand colour coding – red for highly polluted air, orange for polluted, yellow for moderate, light green for clean and green for very clean.

In Paris, data is collected at several spots throughout the city by sensors set up by Airparif, an organisation monitoring French air quality. The data used complies with the new European Union air-pollution index developed for the CITEAIR project, which is currently used by about 30 large cities.

The balloon displays two measurements of air quality using Airparif’s data. Firstly, the ambient air quality is indicated by the colour of the balloon, using three projectors that are located upon the envelope’s equatorial plane, providing good night-time visibility. Secondly, air quality near major traffic junctions is indicated using a high-power rotating laser beam that sweeps the lower half of the envelope.

The Paris Aérophile balloon is filled with 6,000 cubic metres of helium and is tethered to the ground with a movable cable controlled by a hydroelectric winch. The environmentally friendly design is based on the Archimedes principle, and can lift up to 30 passengers (about 2.5 tonnes), without any noise or shaking, to an altitude of 150 metres above the city.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Studying fundamental particles in materials

Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
