John Kenworthy. John Kenworthy B.Sc., F.R.Aes (1883–1940) was an English aviation engineer and aircraft designer.

John Kenworthy appears in the 1901 Census of Darlington, aged 17, living with four sisters, one brother and his parents George and Ellen Kenworthy at 65 Greenbank Road, Darlington, County Durham. His father was listed as a Schoolmaster.

In his early years he was a design assistant at the Royal Aircraft Factory formed out of the HM Balloon factory in 1911 at Farnborough, Hampshire. His first design in 1912 was the B.E.3 (Blériot Experimental), also known as the Goldfish because of its horizontal tail fin. He also designed the H.R.E.2 (Hydro Reconnaissance Experimental), a floatplane version of the earlier B.E.2 designed by Geoffrey de Havilland. Following closely in 1912 was the (B.E.4, B.E.7 and in 1913 the B.E.8) After the outbreak of the First World War in 1914, the Royal Flying Corps (RFC) needed fighter and reconnaissance aircraft from the Royal Aircraft Factory and Kenworthy as Chief designer produced the F.E.8 (Fighter Experimental) from 1916, and the R.E.8 (Reconnaissance Experimental), used from 1917. In 1916 he was part of the project team as chief draughtsman who designed the 150 hp S.E.5 (Scout Experimental), and its follow up, the S.E.5a which arrived several months later with the same basic designs, but a more powerful 200 hp engine.

In 1917 he left the Royal Aircraft Factory and joined the aircraft division of Austin Motors as chief engineer and designer in 1918. He specialised in small light aircraft, designing the prototypes of the Austin Greyhound, the Austin Whippet and the Austin Kestrel, but were not developed further by Austin Motors. In 1922 he joined Westland Aircraft Works and was chief designer at the Aircraft Disposal Co. (ADC Aircraft) in 1923. By 1930 he had designed the Robinson Redwing, which was built at the Robinson Aircraft Company in Croydon and was designed for flying clubs and private use. In 1931, the Aircraft Company was reconstituted and became the Redwing Aircraft Co Ltd. In 1932, as designer and founder of the company, he was appointed to the Board and the Aircraft Company moved their fleet of twelve aircraft to Gatwick Airport. The aerodrome was also purchased and used as the new flying base. In 1934 the Redwing Aircraft Co., moved back to Croydon aerodrome.

Rans S-11 Pursuit. The Rans S-11 Pursuit is an American single-engined, tractor configuration, single-seat, low-wing aircraft, based on the lifting body principle, designed and built by Randy Schlitter. The Pursuit was listed as under development in 1998, but only prototypes were ever completed and the aircraft is not part of the present Rans aircraft line.

Design and development
The S-11 was conceived as a unique single seat sport aircraft, based on the lifting body concept pioneered by NASA in the 1960s. The aircraft design derives 80% of its lift from the aircraft fuselage and associated strakes and only 20% from its straight wings.

The Pursuit is a straked, low wing single or dual seat aircraft with tricycle landing gear and dual rudders. It is made from a welded steel fuselage with aluminum ribs and a composite shell. The prototype's engine was a Rotax 912UL of , with the Rotax 582 of  intended to be offered as an option.

Operational history
A prototype, N2164K, was registered with the Federal Aviation Administration in July 1990 and destroyed on 19 January 1991. Another prototype, N4299Y, was registered with the FAA in June 1991 and had its registration cancelled in March 2001. Another prototype, N7012W, was granted an FAA registration on 5 May 1993.

Accidents and incidents
A prototype S-11, N2164K, was involved in an accident on 19 January 1991. The aircraft suffered an engine failure caused by a seized piston at altitude. The landing was hard and resulted in a fire. The pilot received serious injuries. The National Transportation Safety Board assessed cause factors as engine failure followed by a high descent rate on landing. The aircraft is listed as destroyed.

George (robot). George is a British humanoid robot created by Tony Sale in 1949. The robot was built using scrap metals from a crashed RAF Wellington bomber. George was reactivated in 2010 by Sale and is on display at The National Museum of Computing at Bletchley Park.

History
In 1949 Tony Sale used the scrap metal from a grounded Wellington bomber to build a simple  humanoid robot he named George. The construction cost for the robot was about £15. Actually, this robot could be considered George Mark IV, as Sale had already built a very basic robot in his parents' garage when he was 12 and named it George, plus two later versions.

The last George robot, the only one extant, was built when Sale joined the Royal Air Force in 1949 as a radar instructor at the RAF Debden base in Essex. It could walk, turn the head, move its arms and sit down. It was powered by a pair of motorcycle batteries put inside his chest. The robot could also move his jaw to speak and be controlled by radio remote. The external cover of the body was made in aluminium and duralumin. George was put on display at the open days at the RAF Debden base and also appeared on television.

2010 reactivation
In November 2010 Tony Sale reactivated George after 45 years of total inactivity. The robot had been stored in Sale's garage. The original batteries were replaced with new lithium batteries and some minor fixing occurred. Sale described the process with the words: "I dug him out of the garage where he had been standing for 45 years, I had a fair bit of confidence he would work again and luckily I was right. I put some oil on the bearings and added a couple of new lithium batteries in his legs, switched him on and away he went. It was a lovely moment."

The event gathered worldwide news-media attention, and George's reactivation was shown in the third episode of Wallace and Gromit's World of Invention. After the reactivation, Tony Sale donated George to the National Museum of Computing, where it remains on display to the public.

2020 exhibition
On 15 March 2020, the robot was put up for display as part of the Robots Exhibition on Tekniska museet in Stockholm, Sweden.

Big Sandy Power Plant. The Big Sandy Power Plant is a 268 megawatt (MW), natural gas power plant owned and operated by Kentucky Power Company, a subsidiary of American Electric Power (AEP), on the shores of the Big Sandy River near Louisa, Kentucky. It was established in 1963. It was formerly a coal-fired power plant, but was converted to natural gas in 2016.

Number of Employees: 135
Customers: 175,000+

Emissions Data
2006 CO2 Emissions: 6,830,275 tons
2006 SO2 Emissions: 46,476 tons
2006 SO2 Emissions per MWh:

In January 2009, Sue Sturgis of the Institute of Southern Studies compiled a list of the 100 most polluting coal plants in the United States in terms of Coal Combustion Waste (CCW) stored in surface impoundments like the one involved in the TVA Kingston Fossil Plant coal ash spill. The data came from the EPA's Toxics Release Inventory (TRI) for 2006, the most recent year available.

Big Sandy Plant ranked number 40 on the list, with 915,079 pounds of coal combustion waste released to surface impoundments in 2006.

Big Sandy Plant's Fly Ash surface impoundment is on the EPA's official June 2009 list of Coal Combustion Residue (CCR) Surface Impoundments with High Hazard Potential Ratings. The rating applies to sites at which a dam failure would most likely cause loss of human life, but does not assess of the likelihood of such an event.

The data came from the EPA's Toxics Release Inventory (TRI) for 2006, the most recent year available.

Conversion to natural gas
In 2011, Big Sandy's owner AEP announced plans to switch from coal to natural gas to reduce fuel costs, greenhouse gas emissions, and airborne toxins. In 2012, AEP proposed a billion dollar upgrade to allow it to continue to burn coal and asked Kentucky regulators to approve a 30 percent increase in electricity rates to pay for the work.

Conversion to natural gas was completed on May 30, 2016. The station's Unit 2 cooling tower was demolished via implosion on September 24, 2016.

HHTDD. HHTDD (hexanitrohexaazatricyclododecanedione) is a powerful but moisture sensitive explosive compound. It is essentially an open analogue of the cyclic nitroamine cage compounds such as CL-20. While it is highly explosive, with a velocity of detonation even higher than that of CL-20, HHTDD readily decomposes in the presence of even trace amounts of water, making it unsuitable for any practical applications.

Jansen's linkage. Jansen's linkage is a planar leg mechanism designed by the kinetic sculptor Theo Jansen to generate a smooth walking motion. Jansen has used his mechanism in a variety of kinetic sculptures which are known as  (Dutch for "beach beasts"). Jansen's linkage bears artistic as well as mechanical merit for its simulation of organic walking motion using a simple rotary input. These leg mechanisms have applications in mobile robotics and in gait analysis.

The central 'crank' link moves in circles as it is actuated by a rotary actuator such as an electric motor. All other links and pin joints are unactuated and move because of the motion imparted by the crank. Their positions and orientations are uniquely defined by specifying the crank angle and hence the mechanism has only one degree of freedom (1-DoF). The kinematics and dynamics of the Jansen mechanism have been exhaustively modeled using circle intersection method and bond graphs (Newton–Euler mechanics). These models can be used to rate the actuator torque and in design of the hardware and controller for such a system.

Steel bar. A steel bar, commonly referred to as a "steel", but also referred to as a  tone bar, slide bar, guitar slide,  slide,  or bottleneck,  is a smooth hard object which is pressed against strings to play steel guitar and is itself the origin of the name "steel guitar". The device can either be a solid bar which is held in the hand, or a tubular object worn around the player's finger. Instead of pressing fingertips on the strings against frets as a traditional guitar is played, the steel guitarist uses one of these objects pressed against the strings with one hand, while plucking the strings with the other to gain the ability to play a smooth glissando and a deep vibrato not possible when playing with fingers on frets.

The solid bar is typically used when the instrument is played on the player's lap (across the knees) or otherwise supported in a horizontal position, historically called "Hawaiian-style". It is used in many genres of music, but commonly associated with American country music.

The tubular model is typically used in blues and rock music when the player holds the guitar in the traditional position (flat against the body). It is then called a "slide" and the style called "slide guitar". Early blues musicians inserted a finger in the sawed-off neck of a bottle to use as a slide and the term "bottleneck" became an eponym for this type of blues guitar playing.

Auerlite. Auerlite is a rare North Carolina mineral variety, remarkably rich in thoria, named after Carl Auer von Welsbach, the inventor of the Welsbach incandescent gas mantle. It is considered to be a phosphorus bearing variety of thorite.

Description 
It was originally described as a hydrous silico-phosphate of thorium, ThO2(SiO2,⅓P2O5)+2H2O, i.e. thorite in which part of the silica is replaced by phosphoric acid. The crystals are tetragonal, lemon-yellow to brown-red in color, and sub-translucent to opaque. The mineral is very brittle; its hardness is 2.5 to 3, and its specific gravity 4.422 to 4.766, the darker crystals having the greatest density.

Analysis gave the following results: —

Locations 
This mineral has hitherto been found at only two places in Henderson County, North Carolina, namely, at the Freeman mine, and on the Price land,  to the southwest. At both places it occurs in disintegrated granitic or gneissic rock, intimately associated with zircon crystals, on which it is often seen implanted.

Etymology 
As this mineral was found while mining the zircons necessary to supply the demand caused by the invention of the system of incandescent gas lighting of Carl Auer von Welsbach, the authors of the original description proposed to name it Auerlite in his honour.
