Question: What non-profit organization did one of the builders of the UC1 Freya co-found?

full_context: Document 1: Ampyx Power: 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.

Diamandis ( ; born May 20, 1961) is a Greek American engineer, physician, and entrepreneur best known for being the founder and chairman of the X Prize Foundation, the co-founder and executive chairman of Singularity University and the co-author of "The New York Times" bestsellers " and ." He is also the former CEO and co-founder of the Zero Gravity Corporation, the co-founder and vice chairman of Space Adventures Ltd., the founder and chairman of the Rocket Racing League, the co-founder of the International Space University, the co-founder of Planetary Resources, founder of Students for the Exploration and Development of Space, and vice-chairman and co-founder of Human Longevity, Inc.
Document 3: Deepsea Challenger: Deepsea Challenger (DCV 1) is a 7.3 m deep-diving submersible designed to reach the bottom of Challenger Deep, the deepest-known point on Earth. On 26 March 2012, Canadian film director James Cameron piloted the craft to accomplish this goal in the second manned dive reaching the Challenger Deep. Built in Sydney, Australia by the research and design company Acheron Project Pty Ltd, "Deepsea Challenger" includes scientific sampling equipment and high-definition 3-D cameras, and reached the ocean's deepest point after two hours and 36 minutes of descent from the surface.
Document 4: Rocket Madsen Space Lab: Rocket Madsen Space Lab (often called RML Spacelab) was a laboratory established by Peter Madsen on 16 July 2014 in Copenhagen, after he left Copenhagen Suborbitals.
Document 5: Argonaut Junior: The Argonaut Junior was the first successful submarine built by engineer Simon Lake. Her main attribute, like that of the sub built by Lake in 1897, Argonaut (submarine), was an air lock. Her dimensions were length 14ft, beam 4 ft, depth 5 ft. Different sources incorrectly identify "Argonaut No 1", and "Argonaut No 2" as the name of this vessel. "Argonaut No 1" was built in 1897 and is 36 feet in length, "Argonaut No 2" was a reconstruction of "Argonaut No 1" finishing in 1900 with a length of 60 feet and significantly different profile.
Document 6: Peter Kamnitzer: Peter Kamnitzer (1921–1998) was a German-born American architect. Born in Germany, he emigrated first to Israel and secondly to the United States, where he settled in Los Angeles, California. He was a Professor of Architecture at the University of California, Los Angeles (UCLA). With NASA and General Electric, he invented a graphic design tool used to predict what impact buildings would have on environments. He was a proponent of adding greenery and leisurely facilities to apartment complexes. He designed many residential buildings in Downtown Los Angeles, including public housing.
Document 7: Russian submarine Forel: Forel (Russian: Форель , German: "Forelle" - Trout) was a midget submarine designed by Raimondo Lorenzo D’Equevilley-Montjustin and built by Krupp in Kiel, Germany. The design was an experimental design built as a private venture by Krupp in hopes of attracting a contract from the Imperial German Navy. Although the design proved moderately successful, the submarine did not attract German naval attention. She was purchased by the Imperial Russian Navy in 1904 and served with the IRN until she was lost in a diving accident in 1910. She had the distinction of being the first submarine to have been built in Germany, preceding SM U-1. "Forel" was succeeded in service by the "Krab" class (one ship).
Document 8: Speleonaut: Speleonaut (named from the Greek words for "cave" and "sailor") is the submersible used by the cave diver Jochen Hasenmayer. After the 1989 decompression accident that left his legs paralyzed, Hasenmayer designed the "Speleonaut" with his friend Konrad Gehringer in order to continue exploring the Blauhöhle cave system, which begins at the base of the Blautopf spring in the Swabian Jura mountain range. The "Speleonaut" is 72 cm wide and has nine engines, making it easy to maneuver in all directions. It is the first submarine designed specifically for the exploration of caves. According to Hasenmayer, the "Speleonaut" has been tested in Lake Constance to a depth of 105 m and has a design limit of 180 m .
Document 9: UC3 Nautilus: UC3 Nautilus is a privately built Danish midget submarine. It was built over a three-year period as an art project by Peter Madsen and a group of volunteers, and cost approximately US$200,000 to build (1.5 million DKK). The submarine was Madsen's third submarine design, and at the time of launch on 3 May 2008, was the largest privately built submarine in the world.
Document 10: UC1 Freya: Freya or "UC1 Freya" (in Danish: "Freja") was the first private Danish submarine, and thus first amateur electric sub in Denmark. It was built by Peter Madsen and Claus Nørregaard in 2001-2002, as a demonstrator to try submarine technology. Having made over 500 dives, it was decommissioned, as it was not designed for a long service life. It was decommissioned in 2006 after UC2 Kraka had been worked up. The submarine was then docked and allowed to decay. Final decontamination was done, and it was towed out to sea by UC3 Nautilus, in August 2008, and sunk as an artificial reef near Copenhagen.
Document 11: Freeman Cruisers: Freeman Cruisers was a British manufacturer of cabin cruisers that was active between the years of 1957 and 1983. It took its name from its founder, John Freeman. Freeman had been previously manufacturing caravans and towing trailers before Second World War broke out, but production ceased due to the war. In 1983, the assets of the company were sold to "Sheridan Marine", which still produces spare parts and sells used boats from their boatyard in Moulsford, Oxfordshire. Over 28 models of boat were produced by the company, and they are frequently seen on the navigable waterways of the UK. In addition, Freeman Cruisers are easily able to go to sea, with a few slight modifications to their plumbing and flushing systems.
Document 12: Peter Madsen (inventor): Peter Langkjær Madsen (] ; born 12 January 1971) is a Danish aerospace engineering enthusiast, "art engineer", submarine builder, entrepreneur, co-founder of the non-profit organization Copenhagen Suborbitals, and founder and CEO of RML Spacelab ApS.
Document 13: Boyan Slat: Boyan Slat (born 27 July 1994) is a Dutch inventor, entrepreneur and Aerospace Engineering student drop-out. He was born to Croatian immigrants from Istra.
Document 14: UC2 Kraka: Kraka, or "UC2 Kraka" was an amateur-built midget submarine completed in 2005, the first diesel-electric amateur sub in Denmark. It was built by Peter Madsen, Claus Nørregaard and several other people. The overall length was 12.6 meters and it displaced 6 tonnes. The propulsion was diesel-electric with a 16 hp diesel engine and an 8 hp electric motor. Kraka can be seen at Denmark's Technical Museum in Elsinore (aka Helsingør).
Document 15: Peter L. Jensen: Peter Laurits Jensen (16 May 1886 – 26 October 1961) was a Danish American engineer, inventor and entrepreneur. He founded Magnavox Company and Jensen Radio Manufacturing Company.
