UTC Aerospace Systems. UTC Aerospace Systems (UTAS) was one of the world’s largest suppliers of aerospace and defense products, headquartered in Charlotte, North Carolina, United States. The company was formed in August 2012 when parent United Technologies Corporation merged their existing subsidiary Hamilton Sundstrand with the newly-acquired Goodrich Corporation. In 2018, UTC acquired Rockwell Collins which was merged to form Collins Aerospace.

Products

UTC Aerospace Systems was engaged in designing, manufacturing and servicing systems and components for commercial, regional, business and military aircraft, helicopters and other platforms. UTC Aerospace Systems was also a major supplier to international space programs.

UTC Aerospace Systems had two main segments: Aircraft Systems and Power, Control & Sensing Systems. These segments were then broken down into several business units.

The Aircraft Systems consisted of Actuation & Propeller Systems, Aerostructures, Air Management Systems, Interiors, and Landing Systems (formerly Landing Gear and Wheels and Brakes).

The Power, Control & Sensing Systems consisted of Electric Systems, Engine Systems, ISR & Space Systems, and Sensors & Integrated Systems.

UTC Aerospace Systems was also the owner of Ithaco Space Systems, Inc., formerly owned by Goodrich Company. Ithaco has produced items for the field of satellite control since 1962, such as Earth sensors, reaction/momentum wheels, magnetometers and magnetic torquers. In addition to over 100 U.S. satellites, equipment made by Ithaco flew on Japanese, Canadian, French, German, Spanish, Swedish, and Argentinean spacecraft. Ithaco became notable for having manufactured the reaction wheels of the Kepler spacecraft, the Hayabusa spacecraft, the Mesosphere Energetics and Dynamics (TIMED) satellite and the Dawn spacecraft, which developed problems or even failed. The ROSAT reaction wheels lasted over eight years.

UTC Aerospace Systems announced layoffs at Ithaco Space Systems in August 2012 due to Ithaco having been "focused on space programs that have recently seen slower growth", and further layoffs at former Hamilton Sundstrand.

Limmattal tramway. The Limmattal tramway (, LSB) was a metre gauge electric tramway that operated in the Limmat Valley, situated in the Swiss canton of Zürich to the west of the city of Zürich. Because of the prominent display of the initials LSB on the line's distinctive yellow trams, the line was popularly known as the Lisebethli.

The line opened in 1900 as an  long interurban line from the former Zürich city boundary at Letzigraben, via Altstetten (Farbhof) and Schlieren to Dietikon. A  long branch from Schlieren to Weiningen followed in 1901. A connection with Zürich's city trams, then operated by the Städtische Strassenbahn Zürich or StStZ, was made at Letzigraben. In its early life the line was beset by problems with its level crossings over the Swiss Northeastern Railway at Farbhof and Schlieren, which the trams were only permitted to cross empty, leaving their passengers to walk.

By the late 1920s the track was in poor condition, although by then the level crossings had been replaced by bridges. The line between Schlieren and Dietikon closed in 1928, whilst that between Schlieren and Weiningen closed in 1931, at the same time as the rest of the line from Letzigraben to Schlieren were acquired by the StStZ. In 1950, the StStZ was renamed the Verkehrsbetriebe Zürich or VBZ. The section of route between Farbhof and Schlieren was closed in 1955, being replaced by a westward extension of Zürich trolleybus route 31. The remaining section, between Letzigraben and Farbhof, is still in use, having been integrated into the Zürich city tram network as part of Zürich tram route 2.

One of the line's trams, numbered Ce 2/2 2 and dating from 1900, is preserved at the Zürich tram museum. It sees occasional operation and is painted in the line's yellow livery. It is often seen with a small postal trailer that was used to carry mail on the line.

The Limmattal light rail line was opened in December 2022, linking Zürich Altstetten railway station to Killwangen and using a roughly similar alignment to the Limmattal tramway's former route between Farbhof and Dietikon. As part of this development, Zürich tram route 2 was re-extended over the new line between Farbhof and Schlieren, replacing the trolleybus route.

GRID Alternatives. GRID Alternatives (GRID) is a national 501(c)(3) nonprofit organization based in Oakland, California. Founded by Erica Mackie and Tim Sears in 2004, it installs solar power systems and provides job training for underserved communities and operates in the United States, Mexico, Nicaragua, and Nepal.

History 
Grid, styled "GRID," was founded during the 2001 California energy crisis by Erica Mackie, P.E., and Tim Sears, P.E., two engineering professionals. According to a U.S. Environmental Protection Agency program profile, it "piloted its flagship Solar Affordable Housing Program in the San Francisco Bay Area in 2004, and subsequently expanded to other parts of the state."

In 2008, the company was selected by the California Public Utilities Commission to serve as the statewide program manager for its Single-family Affordable Solar Homes (SASH) incentive program, prompting an expansion across the state.

In 2013, Grid expanded its work outside of California for the first time in Colorado.

GRID Mid-Atlantic, serving Washington, D.C., Maryland, and Virginia, was launched in September 2014. In 2017, GRID Alternatives Mid-Atlantic was selected to administer Solar Works DC, a program of the Washington, D.C. Department of Energy & Environment (DOEE) and Department of Employment Services (DOES).

Regional affiliates 
Grid has nine regional affiliates; seven serving California and offices in Denver, Colorado and Washington, D.C. It also partners with Indigenous tribes throughout the country through its National Tribal Solar Program, of which Tim Willink, from Pueblo Pintado, New Mexico, of the Navajo Nation, is director. Grid has installed over 900 residential solar systems with tribes and brought solar PV to the vast majority of homes on the Bishop Paiute Reservation in California.

In September 2017, regional affiliate GRID Alternatives Tri-State, serving New York, New Jersey and Connecticut, closed due to a recent Federal trade case decision that created uncertainty around future solar panel prices. In their press release, however, the company stated,

Salcca-Pucara hydroelectric project. Salcca-Pucara hydroelectric project is a hydropower project in Peru. The project envisages transferring water from the Río Salcca into the Vilcanota River and an electrical power output of 130 megawatt. The net worth of the project planned is $300,000,000. The start of construction work was planned to occur in September 2015.

Concerns have been raised that electricity from the plant will primarily benefit mining companies and will result in soil contamination and damage to agriculture, as river flows will be altered. There has been opposition, including strikes in 2007 and protests in the two following years which resulted in a temporary suspension of the project. Nevertheless, after negotiations in December 2012 the last community whose permission was outstanding approved the project of the Cuzco-based company Ege Cuzco. Opposition nevertheless continued, with a 2014 report of the ombudsman of Peru indicating the possibility of social conflict.

Ravina Project Toronto. The Ravina Project is a privately run research project, dedicated to educating people about the impacts of home ownership on climate change.

Overview
Susan and Gordon Fraser, a retired couple who converted their 1920s-era Toronto home into an engineering science experiment starting on November 1, 2006. The home features solar panels which in turn charge batteries to supply energy to the house when grid connectivity is disrupted, as well as a bi-directional interface to the power grid, permitting the home to both draw from and supply to the grid. The home also features a variety of applications for insulating walls, windows, and doors.

In 2008 the solar array was modified using an extendable arm made for satellite TVs in order to tilt the solar panels to maximize energy generation. The array can be viewed at any time, via a camera mounted on a neighbour's roof, and the array can be re-positioned via a computer in the home. The Ravina Project publishes data frequently to indicate how well a particular improvement contributes to heating efficiency or power generation, and regularly produces research papers to explain the impact of particular endeavours.  For example, one recent paper reveals the Ravina Project achieved a 31.9% cost savings on heating bills over the baseline, measured in 2005. In addition to cost-savings, the Ravina Project is able to supply electricity to neighbouring homes, as 60% of the energy collected from the home's solar panels gets fed back to the grid. Susan and Gordon Fraser present on their research often.  At the Ontario Good Road Association conference in February 2017, Gordon Fraser reported that laying panels flat during the winter was the orientation that produced most effective electricity generation.
