Grob G102 Astir. The G102 Astir is a single-seat glassfibre Club Class sailplane, designed by Burkhart Grob and built by Grob Aircraft. It was the first Grob-designed sailplane, with the first flight in December 1974. Grob had previously built the Schempp-Hirth Standard Cirrus under licence.

Design and development
The Astir CS [Club Standard] is of composite (fiberglass/resin) construction, has a large wing area, a T-tail and water ballast tanks in its wings. The large wing area gives good low-speed handling characteristics but its high-speed performance is inferior to other Standard Class gliders. In early versions, some of the fuselage frame was wood but this was replaced with a light alloy casting which sometimes cracked after heavy landings. The tail dolly is unusual by being a loose fit into a vertical hole and able to fall free if take-off is attempted with the dolly in place.

A slightly improved Standard Class version, the CS 77, was introduced in 1977. It has a different rudder profile and a slimmer fuselage similar to that of the Speed Astir. The Standard II and Standard III versions followed in the early 1980s, reverting to the higher-profile fuselage and with a reduced empty weight and an increased payload.

The Astir CS Jeans was similar to the CS 77, but had a fixed mainwheel and a tailskid. Its cockpit was fitted in blue denim. Later versions were the Club II and the Club III which also had fixed gear, but the Club III had a tailwheel.

The numbers built of each type were: 536 CS, 244 CS77, 248 CS Jeans, 61 Club/Standard Astir II and 152 Club/Standard Astir III. A flapped version called the G104 Speed Astir was also produced.

The latest in the Astir line is the G102 Standard Astir III, designed by Burkhart Grob and built by Grob Aircraft as a development of the original G-102.

One Astir (now residing at the Steven F. Udvar-Hazy Center), flown by Robert Harris, broke the world absolute altitude record at 49,009 ft (14,938 m) on 17 February 1986. This record lasted until 2006.

Shigeyuki Hori. Shigeyuki Hori is the principal designer of Toyota's acclaimed Hybrid Synergy Drive hybrid motor system which is in use by several vehicles including the Prius and Lexus RX Hybrid. An executive chief engineer in Toyota Motor Corporation, Dr. Hori served as chief engineer for more vehicles simultaneously than any other person in the company's history, by taking charge of the Prius, Celica, MR2, Caldina, Opa, Avensis, and Scion tC development efforts in the early to mid-2000s.

Career
Shigeyuki Hori spent nine years studying at the University of Tokyo, where he earned a PhD in bioengineering.  At Toyota Motor Corporation, he developed the Toyota Cost Calculation System, a method of determining the cost of each part that goes into a vehicle, and thus computing the total expense of building each car.  Prior to this system, designers had estimated new car costs using prior comparison models.  The development of the Toyota Cost Calculation System earned Dr. Hori the nickname "Dr. Cost-Magician" within the company, and he was given further vehicle development positions.  

In the early 2000s, Dr. Hori was named executive chief engineer of the second generation Toyota Prius. He also took charge of the Celica and MR2 projects, destined for worldwide markets, the Avensis for Europe, the Caldina and Opa for Japan, and the Scion tC for the US. An avid test track driver, Dr. Hori alternated between his design duties and high-speed vehicle drives.  At the culmination of the Toyota Prius development project, Dr. Hori and his team had amassed 530 patents for the Hybrid Synergy Drive system and other elements of the Prius design.

GM Powertrain Torino. GM Powertrain Torino is a powertrain engineering center headquartered in Turin, Italy and was founded in 2005. In September 2008 the center moved into its new Politecnico di Torino facility, making General Motors the first automotive company to become a physical part of a university campus. The Engineering Center currently engineers and develops diesel engines, controls and propulsion systems, and employs over 650 people.

GM Powertrain Europe was a center for development of diesel engines and related electronic control of GM globally, and designs propulsion systems for Opel, Chevrolet, GMC and Buick. From design to the study of virtual components or tests on the engine benches – everything took place in the laboratories and test cells of GM Powertrain Europe in Turin.

GM Powertrain Europe Turin represented a strategic asset for GM globally. In Europe, the engineering center provides Opel vehicles with premium diesel technology, like the all-new 1.6 CDTI engine, the quietest diesel in its class that has earned the nickname ‘Whisper Diesel’. Diesel engines of the future which are designed in Turin all share common characteristics: high-tech solutions offering moderate fuel consumption and  emissions. GM sold it to Punch in 2020, following the exit of GM from European market. Since Peugeot already had Diesel engines, the design center was useless to GM, therefore it was sold out.

During the alliance between Fiat and GM, it was part of Fiat-GM Powertrain.

Outdoor fireplace. An outdoor fireplace is a place for building fires outside of the home.  Similar in construction to an indoor fireplace, an outdoor fireplace is usually added to a stone, brick, or concrete patio.  It often consists of a firebox and a chimney.  The firebox is typically constructed with a smoke shelve incorporated although straight firebox designs are not uncommon since chimney draft is not always a concern for an outdoor fireplace. As with indoor fireplaces, an outdoor fireplace requires cleaning and maintenance to keep it looking and working at its best. While an outdoor fireplace may not need to be cleaned as often, it will need to be cleaned regularly in order to keep it reasonably tidy and maintained and to remove ash build.

While indoor fireplaces are traditionally designed for heating, an outdoor fireplace is usually used for cooking.  Many are designed to double as wood-fired ovens that allow homeowners to create meals such as pizzas and casseroles.  Entire outdoor kitchens can evolve from the fireplace.

An outdoor fireplace can simply be a decorative element, which allows homeowners to enjoy a crackling fire while entertaining in the backyard.   Some municipalities (e.g. Toronto) prohibit purely decorative fireplaces.

Plymouth Voyager 3. The Plymouth Voyager 3 was a minivan concept car revealed by Plymouth in 1989. Part of the car's aerodynamic design featured a glass roof. One thing that was unique about this car was that in a sense it was a miniature tractor-trailer; the cab separated from the back of the car and could be driven by itself. The rear wheels of the cab were hidden (notice on image) when it was all in one piece.

Each segment of the vehicle contains its own four-cylinder engine, which are electronically-coordinated to deliver power independently or in concert.

The Voyager 3 was credited to Chrysler Designer Tom Gale (who also penned the Dodge Viper and Plymouth Prowler) by one source that also called it "the worst concept car of all time".

This concept car debuted at the 1990 Chicago Auto Show walkaround video in 1990.

Soloy Pathfinder 21. The Soloy Pathfinder 21 was a twin-engined, single-propeller, turboprop aircraft. It is a modification by Soloy Aviation Solutions of a Cessna 208 Caravan airframe. First flown in 1995, the aircraft was essentially a stock Cessna 208 airframe that has been stretched by  with structural reinforcement, powered by twin Pratt & Whitney Canada PT6D-114A engines in a side-by-side Dual Pac configuration in place of the original single engine.

The aircraft performed its last flight in the late 1990s and was stored for more than 20 years, before being parted out and scrapped.

Design and development
Soloy modified a Cessna 208 to construct a prototype Pathfinder 21, with its first flight in 1995. The Dual Pac PT6D-114A engine used in the Pathfinder 21 gained its FAA Supplemental Type Certificate in 1997. Soloy was attempting to obtain FAA certification for the aircraft conversion, but after completing over 80% of the certification work, Soloy announced that it was halting the entire program. The CEO explained that the FAA requires aircraft with more than nine passengers to have the airframe meet tougher restrictions required by Federal Aviation Regulation (FAR) Part 25, which is a practical impossibility, since the Cessna 208 does not meet those requirements. This requirement made marketing the airplane unfeasible, as the expanded passenger cabin was a major reason for the stretch to begin with.

Brasilsat B1. Brasilsat B1 is a Brazilian communications satellite launched on August 10, 1994, by an Ariane rocket model 44LP at Guiana Space Centre which is located in Kourou, French Guiana.

History
It was constructed by the United States and Brazil and is classified as a second generation satellite. It is larger and more powerful than the previous generation of satellites.

The Boeing Company (which chose to expand its presence in another aerospace field of satellite communications by purchasing Hughes Electronics Corporation, the builder of Brasilsat B1 and B2) contracted the acquisition of three satellites from Hughes. As part of the contract, Hughes would divide the work with Promon Engenharia SA of São Paulo. Brasilsat B1 and B2 were tested by the Institute of Space Research - INPE of São José dos Campos, Brasilsat B3 and B4 were tested in the Hughes laboratories.

The contract also included renovation of sensor equipment and telemetry, provided by Guaratiba Center for Satellite Signaling, located in Rio de Janeiro, as well as automation and installation of security equipment in the Tanguá Control Station.

Current status
In March 2007, Brasilsat B1 was moved from its former orbital position at 70.0°W to 68.0°W and replaced by Brasilsat B4. On June 2, 2008 Brasilsat B4 was moved from its new position to 84.0°W and replaced at 70.0°W by Star One C2. Brasilsat B3 is currently at 75.0°W.

Of the four Brasilsat satellites, only B3 is still transmitting signals as of July 2021. B4 was retired in June 2021.

Colloid thruster. A colloid thruster (or "electrospray thruster") is a type of low thrust electric propulsion rocket engine that uses electrostatic acceleration of charged liquid droplets for propulsion. In a colloid thruster, charged liquid droplets are produced by an electrospray process and then accelerated by a static electric field. The liquid used for this application tends to be a low-volatility ionic liquid.

Like other ion thrusters, its benefits include high efficiency, thrust density, and specific impulse; however it has very low total thrust, on the order of micronewtons. It provides very fine attitude control or efficient acceleration of small spacecraft over long periods of time.

Flight use
Eight electrospray thrusters were first used in space on the NASA ST-7 ESA LISA Pathfinder mission, to demonstrate disturbance reduction. Having logged roughly 1,400 hours on-orbit, the Busek built thrusters system met 100% of their mission goals for the LISA Pathfinder mission.
  
By the end of April 2015, Busek had developed a smaller electrospray colloid thruster capable of generating 20 mN in a 17.8 x 17.8 x 4.3 cm  (7"×7"×1.7") package.

Experiments

In July 2013, scientists from Michigan Technological University and the University of Maryland led by Kurt Terhune demonstrated an electrospray system within a transmission electron microscope (TEM). This led to the discovery that the TEM environment formed needle-like structures on the thruster disrupting the way the electrospray system works.

The LunIR, formerly known as SkyFire, nanosatellite, launched on the 16th of November 2022 as a secondary payload on the maiden flight of the Space Launch System for a lunar flyby, will demonstrate the use of this propulsion system.

Friction tape. Friction tape is a type of woven cloth adhesive tape, historically made of cotton, impregnated with a rubber-based adhesive.  Sticky on both sides, it is mainly used by electricians to insulate splices in electric wires and cables. The rubber-based adhesive provides a degree of protection from liquids and corrosion, while the cloth mesh protects against punctures and abrasion. It has been supplanted by PVC-based electrical tape except commonly used for over wrapping.

Other uses 
Friction tape is commonly used to improve the grip on various sporting implements, including tennis racquets, baseball bats, and hockey sticks.  It is also used similarly on the handlebars of bicycles, dirt bikes, lawnmowers, and other small machines that require gripping or steering.
