Proposed interstate water pipelines to California. Proposed interstate water pipelines to California include interbasin transfer projects to divert water from other Western states and provinces, including Oregon, Washington, Alaska and British Columbia.

A Canadian entrepreneur's plan published in 1991 diverted water from eastern British Columbia to the Columbia River, then envisioned a 300-mile pipeline from the river through Oregon to a reservoir near Alturas, California.

The former governor of Alaska, Walter J. Hickel, proposed a water pipeline from his state to California in 1991, which was quickly criticized for being too expensive, environmentally problematic, and "too far-out". The Office of Technology Assessment (OTA) published a report in 1992 considering an implementation of the plan using a subsea pipeline running down the Pacific coast between the two states. The OTA plan concluded that conservation, water banking, and changing water pricing schemes would be more cost effective than building the pipeline.

A 2012 Bureau of Reclamation study investigated schemes to bring water to California using an undersea pipeline from the mouth of the Columbia River on the Oregon–Washington border, importing icebergs, and using conventional seagoing tankers.

The 2015 California drought brought pipeline proposals back to the public consciousness, abetted by celebrities Rush Limbaugh and William Shatner, the latter proposing a Kickstarter campaign to raise $30 billion to fund such a pipeline from Washington state.

, there were no interstate water pipelines to California.

Asterix (tug). Asterix was a small tug/mooring launch which capsized and was a total loss in March 2015 while operating at the marine terminal of Fawley Refinery in Southampton Water, England

Description and service
Asterix was a small tug, used for towing and mooring at ExxonMobil's Fawley oil refinery in Hampshire, England. She was a standard "StanTug 1205" built in 2013 by Damen Group of Gorinchem, Netherlands and one of a pair of tugs they delivered to Fawley in 2014.

The tug measured 25 gross tons and was 13.08 metres in length, 5.28 metres beam and with a service draught of 1.85 metres. Her twin engines totalled 442 kW giving a towing power of 9 tons bollard pull. Asterix was normally operated by a crew of two and was in service with Solent Towage Ltd, a UK subsidiary of Norwegian shipowner Østensjø Rederi AS of Haugesund.

Capsizing and loss
On the evening of 30 March 2015, while assisting the Luxembourg-registered oil tanker Donizetti to sail from Fawley, Asterix was "girted" and capsized, later sinking. One crew-member was thrown clear and quickly rescued, despite high winds, but the other was trapped in the partially flooded wheelhouse for more than one hour. He was subsequently seen when the tug briefly rolled upright and only then rescued by breaking a wheelhouse window. The successful raising of Asterix was announced on 12 April 2015, though she was subsequently declared a total loss.

Johann Heinrich Ehrhardt. Johann Heinrich Ehrhardt, also spelled Erhardt (29 April 1805 – 29 April 1883), was a German locomotive manufacturer and inventor.

Early life 
Ehrhardt was born on 29 April 1805 in Zella St. Blasius, Saxe-Gotha-Altenburg. He was the son of a poor gunsmith who worked in Jäger'schen wire drawing plants. When a master gunsmith visited Ehrhardt's parents, he saw Ehrhardt's technical skills and allowed him to become an apprentice gunsmith. Ehrhardt's first job as a journeyman was at the mint in Gotha.

Work in Belgium 
Ehrhardt moved to Belgium in 1831. He worked for an optician in Brussels for half a year before moving with the John Cockerill company to Seraing, where he worked in steam engineering. While working with dewatering machines, he invented a rear cargo compartment. 

To acquire theoretical knowledge for future work, Ehrhardt went to the Polytechnic Institute in Düsseldorf for three months, starting in November 1833. That same year, preparations began for the construction of Le Belge, the first steam locomotive manufactured in Belgium. The locomotive was completed in 1835 by Robert Stephenson and Company, for use on a planned railway from Brussels to Mechelen. 

In 1836, Ehrhardt attended the Arts and Crafts School in Düsseldorf for further theoretical studies and to improve his skills in technical drawing. Afterward, he returned to his home in Zella-Mehlis.

Saxon engineering company 
While at a trade fair in Leipzig in October 1838, Ehrhardt met one of the directors of the Saxon engineering company in Chemnitz, who hired him to build steam engines and locomotives. 

From 1839–1840, Ehrhardt helped to develop the Teutonia and Pegasus locomotives. The Teutonia was provided for the Magdeburg–Leipzig railway, but could not be put into operation because it was too heavy for the railway's infrastructure. It was instead sold to the Magdeburg-Steamship Company. The Pegasus was acquired, after one year of probation, by the Leipzig–Dresden Railway Company, which used it until 1861. 

From 1843 to 1868, Ehrhardt worked in Dresden as the chief machinist for the Saxon-Silesian railway company, renamed Saxon State Railways after its nationalization in 1851. He invented the two-sided brake with oscillatory waves in 1847, and the portable Ehrhardtsche scale to control axle loads in 1879. He also helped to improve the preheating of condensation devices.

Later years 
Ehrhardt's students included 18 machine masters at other railway companies, professors in Chemnitz and Freiberg, factory owners, and directors of major German and Austrian machine and textile factories.

His nephew, Heinrich Ehrhardt (1840–1928), was a successful inventor, industrialist and entrepreneur.

In 1869, Ehrhardt went to live in Radebeul, Germany. He died there in 1883, at the age of 78.

Calumet Snobird Explorer. The Calumet Snobird Explorer was an American autogyro designed  and produced by Calumet Motorsports of Lansing, Illinois, introduced in May 1997. Now out of production, when it was available, the aircraft was supplied as a kit for amateur construction.

Design and development
Calumet Aeronautics, owned and operated by Tommy Milton, designed an entry level Ultralight gyroplane. Calumet Aeronautics then purchased the assets of the SnoBird Aircraft Company. After moving the assets from Bristol, TN. to Lansing, IL. Tommy Milton and partner, George Smundin inventoried the SnoBird assets and decided to put the entire Snobird line back in production after evaluating  the design integrity and high quality of the manuals. Tommy and George decided to put the Snobird line back into production. The company name was changed to Calumet Motorsports due to the difficulty of purchasing bearings and other critical components. The gyroplane business grew and an additional partner was taken on who, eventually bought out Tommy and George.
The new owner later sold the business.
The new owner sold parts of the business back to Calumet Motorsports. The new owner resold the business once again and the design remains out of production.

The Snobird Explorer was designed as a low-cost, entry-level autogyro, to comply with the US FAR 103 Ultralight Vehicles, including the category's maximum empty weight of . The aircraft has a standard empty weight of . It features a single main rotor, a single-seat open cockpit, tricycle landing gear and a twin-cylinder, air-cooled, two-stroke, single-ignition  Rotax 447 engine in pusher configuration. 

The aircraft fuselage is made from a combination of composite material and aluminum and features a tall tail design to reduce engine-induced yaw. The kit was supplied with jig pre-drilled holes and was powder coated. Its two-bladed rotor has a diameter of . Full fuel is .

The standard day, sea level, no wind takeoff with a  engine is  and the landing roll is .

Operational history
By 1998 the company reported that one aircraft had been completed and was flying, with customer deliveries to commence later in 1998.

In April 2015 six examples of Snobird autogyros of all manufacture were registered in the United States with the Federal Aviation Administration, although a total of 14 had been registered at one time.

Tellier T.3. 

The Tellier T.3 was a French two-seat patrol biplane flying-boat designed and built by Société Alphonse Tellier et Cie à Neuilly (Tellier) and also produced by Société Anonyme des Établissements Nieuport (Nieuport).

Design and development
Based on the earlier Tellier T.2 the T.3 was a two-bay, unequal-span biplane flying boat powered by a  Hispano-Suiza 8Ac engine in pusher configuration, with the pilot sitting ahead of the engine and the gunner/observer in the nose with a forward-facing Vickers machine gun.

Following test flights by both the Aviation Militaire and the Aéronavale, the Aéronavale ordered ten aircraft and the British Royal Naval Air Service (RNAS) ordered two for gun and camouflage trials at the Isle of Grain. A total of 100 aircraft were built, including 47 by Nieuport, who took over the assets of Tellier.

A development of the T.3 was armed with a cannon in the nose and was designated the T.c.6.

Production of two-seat Tellier T.3s was also carried out in Russia, but no aircraft were assembled. Ten Tellier T.3s were assembled from the wartime parts, in the nascent Soviet Union, at GAZ No.3 (GAZ - Gosudarstvenny Aviatsionnyy Zavod – state aviation plant/factory).

Variants
T.3 Production aircraft built by Tellier and Nieport; Approx 190 T.3s were built, including ten in Russia / Soviet Union.

Nylon TMDT. Nylon TMDT (also known as Nylon 6-3-T) is a type of transparent nylon, useful where transparency and chemical resistance are required in the same application. 
This polymer was launched  by Dynamit Nobel in 1968 under the name Trogamid T. In 1988, the business was acquired by Hüls which later became Evonik.

TMD is derived from isophorone, a trimer of acetone.  The polymerization is unusual for a nylon polymer.  In the first step TMD is reacted with dimethyl terephthalate and methanol is removed to form an amide.  In a second step polycondensation is done to make nylon TMDT.

Trimethylhexamethylenediamine. Trimethylhexamethylenediamine is the name used to refer to a mixture of two isomers of trimethyl-1,6-hexanediamine.
The mixture is used as a monomer in nylon TMDT. It is available commercially under the trade name Vestamin TMD from the company Evonik Industries.

Trimethylhexamethylenediamine is synthesized from isophorone. Isophorone is reduced by hydrogenation to the trimethylcyclohexanol, which is then oxidized with nitric acid (in the same fashion as adipic acid is synthesized from cyclohexane). The diacid, again a mixture of two "trimethyladipic acids", is converted to the diamine via the dinitrile.

Uses
TMD is used as a component in certain curing agents for epoxy resins.

Air bubble entrainment (hydraulics). In hydraulic engineering, air bubble entrainment is defined as the entrapment of air bubbles and pockets that are advected within the turbulent flow. The entrainment of air packets can be localised or continuous along the air–water interface. Examples of localised aeration include air entrainment by plunging water jet and at hydraulic jump. Bubbles are entrained locally at the intersection of the impinging jet with the surrounding waters. The intersecting perimeter is a singularity in terms of both air entrainment and momentum exchange, and the air is entrapped at the discontinuity between the impinging jet flow and the receiving pool of water. Interfacial aeration is defined as the air entrainment process along an air–water interface, usually parallel to the flow direction.

In hydraulic structures, free-surface aeration is commonly observed: i.e., the white waters. The air bubble entrainment may be localised or continuous along an interface (water jets, spillway chutes). Despite recent advances, there are some basic concerns about the extrapolation of laboratory results to large size prototype structures.
