Alumysa. Alumysa was a proposed aluminium smelter to be built in Puerto Chacabuco in Aysén Fjord, Chile. The project began to be planned in the early 1990s, it presented its environmental impact assessment in 2001 and was suspended in August 2003. The project was opposed by salmon farm companies operating in the area for the water pollution they claimed the Alumysa would produce. The project was being developed by the Canadian mining company Noranda. Alumysa was planned to import aluminium oxides to produce 440,000 tons of aluminium annually. Noranda has cited a lack of stable rules as the reason for the withdrawal of the project. Other proposed reasons for the suspension of the project include that production cost turned out to be higher than originally thought given a rise in the cost of energy and the fact the international aluminium market was by the mid-2000s more competitive with countries in Middle East and Russia having constructed aluminium smelters that used cheap energy.

Arcimoto FUV. The Arcimoto FUV is a battery-electric, three-wheeled motorcycle produced by Arcimoto since 2019. It has a top speed of  and an estimated range of  in an urban environment.

The vehicle takes the form of a car and a motorcycle combined into a tricycle with two wheels on the front and a single wheel on the opposite side and a motorcycle-like twistgrip drive. The narrow and high body was designed to accommodate two passengers in seats placed one behind the other.

History
The creation of the first production Arcimoto car was preceded by a 12-year construction process, which was initiated by a series of 6 prototypes, presented successively as a development of the previous one. The final result of this work was the Arcimoto FUV model, presented in February 2019, deriving its name from the abbreviation of the words Fun Utility Vehicle, expressing the character of the vehicle. The FUV went on sale in the United States, just after its market debut in February 2019. The price for the cheapest copy was set at $17.9 thousand.

In July 2021, a pre-production unit supporting autonomous driving without the participation of the driver was presented.

Vehicle
The FUV's  electric motor allows a top speed of  and acceleration to  in 7.5 seconds. Arcimoto measures its range in a city environment at . The lithium-ion battery with a capacity of 20 kWh also allows the driver to drive at  for  and at  for  on a single charge.

The structure of the body was formed by exposed piping with a large windshield.

Variants
In 2021, the offer of body variants of FUV was also extended to include a delivery variant called Arcimoto Deliverator, as well as a model with an open body without windows called Arcimoto Roadster.

VAQ-144. Electronic Attack Squadron 144 (VAQ-144), "Main Battery", is a United States Navy aircraft squadron based at Naval Air Station Whidbey Island, flying the EA-18G Growler.

History
VAQ-144 can trace its origins to the former Grumman A-6 Intruder squadron VA-196 formerly also based at NAS Whidbey Island that was disestablished in 1997 as the last operational A-6 squadron on the west coast.

VAQ-144
In September 2019 the Navy transitioned a Carrier Air Wing (CVW) VAQ squadron out of the carrier environment to meet demands as an expeditionary unit. The gap in CVW Electronic Attack coverage showed a need for a 15th operational VAQ squadron. VAQ-144 was established on 1 Oct 2021 to meet this demand with a requirement to meet scheduled milestones and achieve full operational capability in fiscal year 2023. In the spring of 2023, the squadron received its first independent aircraft flown with VAQ-144 markings.

Locked Shields. Locked Shields is an annual cyber defence exercise organised by NATO's Cooperative Cyber Defence Centre of Excellence in Tallinn since 2010.  The format is usually that a red team simulates a hostile attack while blue teams from the participating nations simulate their coordination and defence against this.

The performance of teams is assessed using a mix of automated and manual scoring.  In 2022, there were 24 teams with an average of 50 experts in each team.  The team from Finland was declared as the 2022 winner for the excellence of their situation reporting and solid defence.

Prestwick Dragonfly MPA Mk 1. The Dragonfly was a human-powered aircraft, designed and built by the Prestwick Man Powered Aircraft Group, based at the Prestwick International Airport in South Ayrshire, Scotland.

Design and development 
The aircraft was developed with the specific goal of winning the £50,000 Kremer prize then on offer. Its designer, Roger Hardy, previously had experience with three other HPAs; the SUMPAC, Jupiter, and the Mercury. 

An emphasis was placed on it being a practical, easily-built, machine, with the construction requiring a comparatively low amount of work hours. It was intended to fly outside of ground effect, reaching an altitude of  in 5 minutes, at what was described as "a small but realistic rate of climb."  If attempting the Kremer course, such altitude would permit greater room for manoeuvres without suffering from wing tip stalls. 

The Dragonfly was a wire-braced high-wing monoplane, with a pylon-mounted propeller, and had no unconventional features. The wing had an aspect ratio of 30, and a relatively high wing-loading. The wing could increase its dihedral under flight load, changing from 6° when static, to 10° in flight. Lateral control was achieved by differential ailerons. The wing had a single wooden box-spar, with a secondary structure made from spruce, balsa and polystyrene. The fuselage was of the pod and boom type, a primary structure made using aluminium alloy, and a secondary structure of balsa. The empennage featured a small all-flying tailplane, or stabilator, and a large fin, half of was the rudder. The entire aircraft was covered in Melinex.  The pilot was in a recumbent cycling position, and powered the plyon-mounted propeller.

Construction began in February 1975, and was completed by July. Taxying trials took place in August 1975, however they revealed issues with the craft. It failed to achieve take-off due to the high thrust-line of the propeller and the small moment of the tail-plane. During the following two months, changes made to the aircraft included the strengthening of the rear fuselage, increasing the moment arm of the tail-plane, and changing the pylon-mounted propeller from a pusher to a tractor configuration.

Jane's all the world's aircraft 1976-77 wrote that further flight tests may take place from the Spring of 1977 onward. An article in the February 1977 issue AeroModeller stated that Ron Frost had taken over development of the aircraft.

Mobility mat. A mobility mat (also mobi-mat) is an assistive device that allows wheelchair users access to sandy beaches, dirt trails, or other surfaces that may be challenging for people with limited mobility, like the wooden deck of an ocean pier, or a path covered in wood chips.

Mobi-mats used in Australia are "1.5 metres wide and can be up to 50 metres long." This inclusive technology is a non-slip mat, sometimes with ridges, that provides stability for anyone traveling with the help of wheels, including parents with strollers or wagons, and people using walkers. Most beach mobility mats do not reach the water's edge to prevent tide damage, but they make beaches significantly more wheelchair accessible than they were previously. Some seashore recreation systems may offer beach wheelchairs that users can borrow for the day.

The mats are portable and can be relocated. Increasing numbers of beaches in Florida and California have installed them; availability should be listed on beach websites or included in informational recordings available by phone.
