Women’s Gifts To The World

Necessity isn’t the only mother of invention. Though it wasn’t always easy to get patents or the credit they deserved, women are responsible for many items we use today.

We’ll probably never know how many women inventors there were. That’s because in the early years of the United States, a woman could not get a patent in her own name. A patent is considered a kind of property, and until the late 1800s laws forbade women in most states from owning property or entering into legal agreements in their own names. Instead, a woman’s property would be in the name of her father or husband.

For example, many people believe that Sybilla Masters was the first American woman inventor. In 1712 she developed a new corn mill, but was denied a patent because she was a woman. Three years later the patent was filed successfully in her husband’s name.

Container Greenhouses – The Urban Organic Heaven

What if you wanted to eat locally produced and reasonably priced fresh organic fruits and vegetables during cold winter? Now it is possible, thanks to shipping containers.

Podponics-Pod-feature1

Companies such as Freight Farms and PodPonics have introduced a new business model that converts second hand shipping containers into high-quality greenhouses that can be relocated almost everywhere. Every shipping container is manufactured according to ISO standards and they are also designed to be stacked into multiple layers. This enables the establishment of even bigger greenhouse complexes.

MattLiotta

One major advantage of container farms is that now farms can be located closer to the places where the food will be eaten. Thereby, say, restaurants can minimize their shipping costs and still offer their customers fresh and high quality food. Also the technology associated with the business ensures a safe plantation of fruits, herbs and vegetables.

agriculture_main

Damien Chivialle‘s model of urban farm units (UFU) has a system that uses live fishes and to to fertilize and recycle the farms water. Every container has a fish tank whose water flows in a closed circuit. The fish feces are broke into pieces that are utilized as fertilizers. The system also produces some methane for the farms secondary energy source. (source)

2000-01-01-00-03-37

Also PodPonics’ solution is said to use 90 % less water because the water is recycled. The roots grow in water, not in soil. This solution minimizes the use of fertilizers and enables the adding of nutrients only as needed (source). PodPonics’ and Freight Farms control systems can both be operated with a smart phone.

urbanfarmunit02

The use of shipping containers as green houses seems to enhance the nutritional values of vegetables, herbs and fruits. It also enables companies to produce them closer to the people who end up eating them. Because of a really low Co2 footprint and lack of pesticides, urban farms create ultimate food safety. Now this food safety can also be enjoyed by average consumers because the cost of maintenance of urban farms seem to be feasible. For example PodPonics’ containers cost US 1800 to 2800 depending on their condition (source).

urbanfarmunit05

In order to establish an urban farm, shipping containers need to be purchased. Shanghai Metal Corporation is a reliable provider of internationally standardized shipping containers.

Move Along Airplanes – Submarines Overtake Travel

submarine1

China has moved a step closer to creating a supersonic submarine that could travel from Shanghai to San Francisco in less than two hours. Not much is known about the team’s progress because it is a military project, but the SCMP reports that Germany, Iran and the US are working on similar projects.

worldflags

The team from the Harbin Institute of Technology was inspired by a supersonic torpedo invented by the Soviet Union during the Cold War.

Water yields more friction on an object than air, which should mean that a submerged boat or weapon could never travel at the same speed as an airplane.

But the Soviet military figured out how to put a missile inside an air bubble to cheat this rule of science — a process known as ‘supercavitation’. They created the Shakval, a torpedo that could reach speeds of over 379 km/h, much faster than any other torpedo available.

submarinegraph

The Chinese team, led by engineering professor Li Fengchen, sought to apply the same process to a submarine by overcoming two central problems. The submarine would need to be launched at speeds of up to 100 km/h in order to generate the air bubble. It would also require very advanced steering because the ship’s rudder would be inside the bubble, not touching the water. The answer was found in the form of a manmade liquid membrane that would cover the submarine’s surface. The result is a vessel that could reach the speed of sound, crossing the entire Pacific Ocean in approximately 100 minutes. Once supercavitation is harnessed, it could be incorporated into any underwater activity.

Imagine a Summer Without Air Conditioning

Picture this: It’s 35°C, there’s no air conditioning, and you’re packed into a subway of sweaty people. The last generation doesn’t need to imagine in –they lived it.

sweaty2

Before AC, most industry traditionally slowed or stopped in the summer, when buildings were hot and workers were sluggish. Back then, many workers around the world got month long August vacations similar to what workers still get in Europe today, where AC isn’t as popular.

sweaty3

The development of effective temperature control and refrigeration has revolutionized almost every aspect of industry. Without AC, the following things would be virtually impossible: the manufacture of computers and chip sets; data storage centers; the production, delivery, and storage of food; pharmaceutical manufacturing; and chemical manufacturing.

aircon2

AC allowed for exponential advances in medicine and human life expectancy. Air-conditioned hospitals helped defeat malaria, decrease infant mortality, inhibit bacteria, and advance developments in surgery.

airconditioner1

So the humble AC has been life changing, and not just on our comfort levels.

Shanghai metal produces the stainless steel tubes for electric climate products. High-temperature resistant wire is distributed evenly in the stainless steel seamless pipes, while good quality crystallized magnesium oxide powder is filled in the gap. As a result, the heater has not only a sophisticated structure, but also high efficiency. To find out more, please visit our websiteLinkedInTwitter, and Facebook.

Aviation Made Possible By Light Weight Aluminum: A Brief History

The Wright brothers built the world’s first successful airplane on December 17, 1903 in Dayton, Ohio. What was the secret to their success? To keep the weight low enough, the engine block was cast from aluminum, a rare practice for the time. Since then, advancements in aircraft and rocket technology are directly correlated with the advancement and product of aluminum alloys.Take a look at a few key events in the aircraft and aerospace market:

Orville and Wilbur Wright flew the first airplane in 1903.
Orville and Wilbur Wright flew the first airplane in 1903.

The Wright engine, with its aluminum crankcase, marked the first time this breakthrough material was used in aircraft construction. Lightweight aluminum became essential in aircraft design development and remains a primary construction material for all types of aircraft.

The American public was urged to contribute to the aluminum scrap supply to build fighter jets during World War II.
The American public was urged to contribute to the aluminum scrap supply to build fighter jets during World War II.

In 1942, a New York radio station created a show “Aluminum for Defense” to encourage Americans to contribute scrap aluminum to the war efforts. The aluminum was used in to produce one-third of planes built during World War II

The Apollo Command Module housed the first man on the moon in 1969.
The Apollo Command Module housed the first man on the moon in 1969.

In 1969, the National Aeronautics and Space Administration (NASA) launched the Apollo program that was responsible for the lading of the first humans on Earth’s Moon. The Apollo Command Module, which housed the crew accommodations, equipment bays, controls and displays, was made of an aluminum honeycomb-sandwich bonded between sheets of aluminum alloy.

NASA plans to launch the Orion Multi Purpose Crew Vehicle Ascent Abort 2 test flight (AA‑2) from Spaceport Florida Launch Complex 46 in 2018.

Recycling Tyres & Plastic for Steel Production

Recycling Tires & Plastic for Steel Production

The production of steel has become ‘greener’ in recent times with the discovery of using recyclable materials such as rubber and plastic in the production process. The University of New South Wales Australia and steel company OneSteel Ltd have collaborated to achieve a breakthrough which replaces a significant proportion of the coke normally used in Electric Arc Furnaces (EAF) steel making with recycled tyres or plastics that are rich in carbon.

The technology is now a standard practice at two of OneSteel’s plants in Sydney and Melbourne. It is reported that over 1.8 million tyres have been saved from landfill and the technology has replaced the use of over 15,000 tonnes of coal. This has reduced many millions of KWh hours of energy each year while increasing furnace productivity and producing more steel from the same amount of ferrous scrap.

Professor Veena Sahajwalla who is the Director of Centre for Sustainable Materials Research and Technology at the UNSW stated “This greatly improves the steel furnace’s energy efficiency.”

Veena Sahajwalla - High Temperature Furnace

The process which is called ‘Polymer Injection Technology’ has been patented internationally and has been commercialised for international steel makers using EAF, which is responsible for 40 percent of the world’s steel production.

This new technology has the potential to significantly change the steel industry’s environmental footprint, improve the global output of steel and reduce the costs of manufacturers and buyers.

Stainless Steel, the Light at the End of the Tunnel

Stainless Steel comes in a variety of alloys and other product forms. Stainless Steel products will survive even when they are placed in the harshest conditions. For example, Stainless Steel does not need any added products to protect it from corrosion. It also has fire resistance properties that are helpful for the construction of buildings, roads, and tunnels.

stainlessconstruction

 

Recently, more and more tunnels utilize Stainless Steel. Making use of Stainless Steel is an innovative strategy that helps improve the safety of the tunnels that do employ Stainless Steel for its structure. Many tunnels are built to pass through rocks or mountains. Other tunnels are built under rivers, lakes, oceans, and other bodies of water.

tunnelunderrock

Tunnels usually go through a wide variety of conditions daily including surviving through a great range of temperature and high levels of corrosive chemicals. Corrosive chemicals can come from emissions and de-icing salts. Emissions can include many different types of particles including mineral dust deposits, water soluble chlorides, abraded rubber tire fragments, black soot, etc.

Since tunnels go through so much, tunnel engineers have chose to rely upon Stainless Steel. To minimize maintenance and heighten durability, operators of numerous tunnels have intelligently chosen Stainless Steel grades that work best for the tunnel’s environment. For instance, some tunnels are built with Stainless Steel that has a slightest molybdenum content of 6% in order to prevent the failure of fixings.

Molybdenum

Other ways that tunnel engineers depend on Stainless Steel are using them for fire doors, barriers, and reinforcements. Also, they rely on Stainless Steel for failure-proof fixings, which are necessary for attaching lighting, fire-fighting equipment, ventilations, etc. Some tunnels use covers of ventilation made from Stainless Steel. These covers are usually subjected to high levels of corrosive atmospheric gases. Furthermore, since Stainless Steel is a strong fire resistant metal, many tunnels have used the material to support fixed fire fighting systems.

Stainless Steel Ventilation

For instance, the Kehu Tunnel in Helsinki, Finland employs a fixed fire fighting system which comprises of five rows of 16 mm diameter Stainless Steel piping and spray nozzles. In case a fire erupts in the tunnel, the high-pressure system produces a fine water mist that will quench tunnel fires.

Kehu Tunnel’s Fire Fighting System

As one may realize, Stainless Steel is a very powerful and useful material. Stainless Steel is versatile because of its strength, its corrosion resistance properties, and fi re resistance characteristics. Stainless Steel has been able to increase the safety, to reduce damage, and to prevent many disruptions or closings of tunnels.
