Rotortec. Rotortec GmbH is a German aircraft manufacturer based in Görisried, Allgäu. The company was founded by Jochen Steinbeck and specializes in the design and manufacture of autogyros.

The company's initial design was the Rotortec Cloud Dancer I, a single-seat, enclosed cockpit gyro, that uses an innovative electromagnetic clutch for the Carden Drive. This was followed into production by the two-seats in side-by-side configuration Rotortec Cloud Dancer II, which was first shown at AERO Friedrichshafen in 2009. The third design, the Rotortec Cloud Dancer Light, is a simplified version of the Cloud Dancer I, without a cockpit fairing and intended to qualify for the German 120 kg ultralight class as it has an empty weight of 120 kg (265 lb).

All designs are supplied complete and ready-to-fly.

Max Holste MH.20. The Max Holste MH.20 was a French single-engined racing aircraft built to compete in the 1939 Coupe Deutsch de la Meurthe air race but not flying until 1941. A single example was built.

Design and development
In January 1939, the 26-year-old aircraft designer Max Holste began work at l'École de Réèducation Professionnelle, a Paris technical school for training the unemployed for work in the aviation industry, to design an all-metal single-engined racing aircraft. The design, intended to compete in the 1939 Coupe Deutsch de la Meurthe air race, was a mid-winged monoplane with a fixed tailwheel undercarriage. An enclosed cockpit was provided for the aircraft's pilot, situated behind the wing. The planned power-plant was a Béarn vertically-opposed air-cooled twelve-cylinder engine.

The airframe was effectively complete by June 1939, with only the engine awaited, with it being hoped that the aircraft would make its maiden flight by August 1939. This did not occur, however, and the aircraft did not fly until 25 July 1941, powered by a Régnier air-cooled inverted 12Hoo V12 engine.

Robert E. Huffman. Dr. Robert E. Huffman (1931–2008) was an American space scientist and author. He specialized in ultraviolet spectroscopy in the earth's upper atmosphere. Working for the United States Air Force, Dr. Huffman managed the Horizon Ultraviolet Program (HUP) experiments on two Space Shuttle flights: Columbia (STS-4, 1982) and Discovery (AFP-675 on STS-39, 1991).

Dr. Huffman was also the principal investigator for the Auroral Ionospheric Mapper (AIM) on the HILAT Spacecraft and the Auroral/Ionospheric Remote Sensor (AIRS) on the Polar BEAR Spacecraft. In 1983 the Auroral Ionospheric Mapper produced the first pictures of Aurora Borealis made under full daylight conditions. Although the aurora cannot be seen in the visible spectrum during daylight hours, Dr. Huffman's instrument was able to capture an image in the ultraviolet spectrum.

In the early 1970s Dr. Huffman was Program Manager for Project Chaser, a series of launches of Aerobee 170 sounding rockets from Vandenberg AFB Probe Launch Complex C. The purpose of Project Chaser was to measure exhaust plumes from  anti-ballistic missile systems launched simultaneously with Project Chaser.

His memoir "Adventures of a Star Warrior: Cold War Rocket Science on the Space Frontier" was published posthumously.

Rotor Flight Dynamics. Rotor Flight Dynamics Inc was an American aircraft manufacturer based in Wimauma, Florida and owned by Ernie Boyette. The company was founded in 1986 and specialized in the design and manufacture of autogyros in the form of plans and kits for amateur construction.

The company seems to have gone out of business in 2020.

Boyette started his company to produce his Dragon Wing rotorblade designs. Constructed of bonded aluminium and employing a custom airfoil section, they were first marketed in 1989. He used the money made from that successful venture to fund the development of his Dominator series of autogyro designs.

In 2006 the Rotor Flight Dynamics LFINO (Leap Flight In Normal Operations and pronounced by the designers as "ell if I know"), was displayed at Bensen Days. First flown in February 2006, the innovative design was constructed by Boyette and Dick DeGraw as a technology demonstrator and incorporates an enclosed cabin along with a vertical take-off capability.

Endeavour (building). Endeavour is a 30-story high-rise condominium building in Pasadena, Texas, in southeastern Greater Houston.

The building was built in 2008 on the shore of Clear Lake, originally envisioned to be the first of a number of high-rise residential buildings that would be built on the waterfront of the generally low-rise suburban area near the Johnson Space Center. However, damage from Hurricane Ike in late 2008, combined with the property-market downturn of the 2008 financial crisis, led to the developer filing for bankruptcy in May 2009, having sold only 36 of the 80 units. The remaining 44 units were purchased in bankruptcy court in December 2009 by an investment partnership, for $9.5 million plus past-due taxes. The new owners repaired and renovated the building at a cost of $2 million, and relaunched condominium sales in 2010.

Uchurskaya HPP
Hydroelectric power capacity 365 MW, average annual production 2.19 billion kWh.

Kankunskaya HPP
Power generation capacity of 1060 MW, and an average annual production of 4.77 billion kWh. It will be the first-built dam in the complex.

Timptonskaya HPP
Located on the River Timpton, a tributary of the Aldan River, Timptonskaya will have a power generation capacity of 245 MW and an annual generation of 1.48 billion kWh.

Olekminsk HPP
Located on the Olyokma River, a tributary of the Lena River. Includes Olekminsk; total capacity of 2230 MW.

Aldan HPP
Power capacity of 300 MW, average annual generation of 3.6 billion kWh. Another plant, the Verkhne Aldan, will join this station- total generation capacity is expected to be 1000 MW. Commissioning of these projects is expected in 2015–2020.

Economic importance 
The hydroelectric complex should achieve the following objectives:

♦Electricity exports to China, and possibly to South Korea, but only China has expressed interest in buying electric power from Russia.

♦Ensuring a reliable power supply to the Russian Far East oblasts.

♦Ensuring the supply of power to promising mining projects in South Yakutia, especially the Elga coal deposits.

♦Provision of electricity to energy-intensive industries, particularly aluminum smelters.

The cost of construction is estimated at $8 billion, which is less than the Diamer-Bhasha Dam in Pakistan, at $14 billion.
