The Superbus is a prototype high speed electric coach-like limo car that is capable of carrying 23 passengers at speeds of up to 250 km/h on specially designed segregated highway lanes.
 The Superbus project, led by Dutch astronaut professor Wubbo Ockels of the Delft University of Technology until his death in 2014 envisages a comfortable, demand-dependent door-to-door transportation rivaling the car and the train.
 The project, which encompass infrastructure, logistics, safety, reliability and economic viability, in addition to the design of the vehicle itself, has received funding of €7 million, largely provided by the Dutch State.
Frank, Viscount De Winne (born 25 April 1961, in Ledeberg, Belgium) is a Belgian Air Component officer and an ESA astronaut.
 He is Belgium's second person in space (after Dirk Frimout).
 He was the first ESA astronaut to command a space mission when he served as commander of ISS Expedition 21.
 ESA astronaut de Winne serves currently as Head of the European Astronaut Centre of the European Space Agency in Cologne/Germany (Köln).
Ampyx Power is an airborne wind energy company founded in 2008 by Bas Lansdorp and Richard Ruiterkamp.
 It was created after Lansdorp dropped his five-year-long studies of wind energy at Delft University of Technology to found Ampyx Power.
 In 2011, Lansdorp sold a majority of his Ampyx Power shares to fund his new project, Mars One.
 Wubbo Ockels' interest in energy began when he let a kite line slip and it burned his hand.
 He became interested and started to study and research how this could be turned into electricity.
 At Delft University, he formed a team with Bas Lansdorp that worked on developing kites that could retrieve energy from the sky.
 Richard Ruiterkamp became the team leader and he created a fixed wing aircraft that allowed greater controllability and allowing the generation of more energy.
 In 2008 he founded the company with Bas Lansdorp.
 Lansdorp worked on the business aspect, and Ruiterkamp was head of the science division.
 Currently, Ampyx Power has a team of 40 engineers.
 Their current prototype is the AP3 Ampyx Power Airborne Wind Energy System (AWES).
 The system is a tethered aircraft that converts wind into electric energy.
 The aircraft is tethered to an on the ground generator.
 When the aircraft moves and flies, it reels the tether and powers the generator.
 The plane is then reeled in through the tether and then re-released into the air.
Expedition 35 was the 35th long-duration mission to the International Space Station (ISS).
 The expedition started 13 March 2013, and marked the first time a Canadian astronaut – Colonel Chris Hadfield – was in command of the station.
 Expedition 35 was also only the second time an ISS crew is led by neither a NASA astronaut, nor a Roscosmos cosmonaut, after Expedition 21 in 2009, when ESA astronaut Frank De Winne was in command.
NASA Astronaut Group 9 was announced on May 29, 1980, and completed their training by 1981.
 This group, composed of 19 candidates, was selected to supplement the 35 astronauts that had been selected in 1978, and marked the first time that non-Americans were trained as mission specialists with the selections of ESA astronauts Claude Nicollier and Wubbo Ockels.
 In keeping with the previous group, astronaut candidates were divided into pilots and mission specialists, with eight pilots, eleven mission specialists, and two international mission specialists within the group.
Liévin De Winne (Ghent, 24 January 1821 - Brussels, 13 May 1880) was a Belgian portrait painter who painted the official portrait of Leopold I on which the first postage stamp of Belgium was based.
Expedition 21 was the 21st long-duration mission to the International Space Station (ISS).
 The expedition began on 30 October 2009, with Frank de Winne becoming the first ESA astronaut to command a space mission.
Wubbo Johannes Ockels (28 March 1946 – 18 May 2014) was a Dutch physicist and an astronaut of the European Space Agency (ESA).
 In 1985 he participated in a flight on the space shuttle Challenger, STS-61-A, making him the first Dutch citizen in space.
 After his astronaut career, Ockels was professor of "Aerospace for Sustainable Engineering and Technology" at the Delft University of Technology.
Maxime De Winne (born 22 June 1977) is a Flemish actor and theatre producer.
Passacaille records is a Belgian classical music record label, owned by Musurgia BVBA, based in Halle, Belgium.
 The company's artistic director is the flautist and flute-maker Jan De Winne.
