Coal

Coal is a combustible rock made of carbon and small traces of Hydrogen, Sulfur, Oxygen and nitrogen. Coal is mainly sedimentary with the exception of rocks like anthracite coal which is metamorphic. Coal is a fossil fuel and forms over the course of millions of years. When plants are alive, they remove CO2 in the atmosphere release O2. However when the plant dies, it decomposes and all the carbon rich plant matter turns to coal. The process when dead plant matter turns into coal has many stages. The dead plant matter turns into peat and then converted to lignite and finally that transforms eventually into coal, (Sub-bituminous coal --> bituminous coal --> Anthracite).

Unfortunately over 90% of the consumption of coal in the U.S supplies coal fired power stations. This significantly contributes to global warming and the U.N climate agency's recommendation is that all coal reserves should not be used in order to prevent extreme global warming. Surprisingly, there are no laws enforcing this and the U.S exports about 2 trillion pounds of coal each year.In addition, the combustion of coal in power stations puts toxic compounds into the air such as Mercury,sulfur-dioxide, nitrogen oxide, lead, cadmium, trace amounts of uranium,and arsenic. This causes severe health issues such as destroying lung tissue, chronic bronchitis, asthma, cancer, heart disease, and brain damage through the lead and the consumption of mercury via fish. I do not know how coal power plant owners sleep at night with all these health issues they are causing in animals and people.

Natural Gas (INDUSTRIAL APPLICATIONS)

Natural gas, Petrol, Coal, and Gasoline is used in a very wide variety of applications in industry, commercial, residential, and construction. Natural gas is extracted from the earth through a process called Hydraulic Fracturing. Hydraulic Fracturing (Fracking) is a very controversial process because is emits tons of pollution severely affecting the environment.The process uses millions of gallons of water which is combined with chemicals like hydrochloric acid, formic acid, Benzene, a Carcinogen , methanol, ammonium persulfate, glutaraldrehyde and 750 other chemicals chemicals to create Fracking Fluid. This fracking fluid contains acids to dissolve rock to bacteria killing chemicals to kill bacteria living in the shale. In addition, this fracking chemical mix contaminates water that GETS SENT TO PEOPLES HOMES. Therefore, they are sent colossal water containers by the fracking companies because the municipal water supplies get contaminated. Furthermore, residents who live next to these rigs are at risk to many health problems from exposure to Radium which is highly unstable and radioactive. Radium escapes these wells and winds up in the air residents near the fracking wells breathe. In addition, the residents get cancer from all the toxic chemicals in the fracking fluid.

Contaminated tap from fracking is a highly flammable.

Automation (industrial series)

Automation at a car factory on an assembly line

Automation is the use of Control systems to control/operate machinery, processes, boilers, networks, aircraft, and other applications operated mainly without the help of humans. Automation is used when accuracy and quality is crucial because human labor is not as precise and error-free as robots and computers. However, the main reason why automation is used is because it lowers the cost of labor significantly and increases the efficiency of production, making the cost of the product lower and the CEO's getting more money. For example, in 1905, the first commercial automated bottle blowing machine made 720 bottles per hour compared to a crew of 12 which made 120 bottles per hour. Ultimately, this lowered the cost  from 1.80 to 10-12 cents per gross (144 bottles). This can negatively impact the economy because unemployment can increase. Nevertheless automation is used to great degrees in many factories and industries and the term lights out manufacturing refers to when 100% of labor is automated.

Pro's: Increased quality, higher output of products, less expenses, increase in speed of production, dangerous tasks for humans can be replaced (Nuclear power stations, fire, underwater), tasks beyond human ability can be addressed can be accomplished.

Con's: Initial high cost (tons of money in purchasing machinery), environmental issues in production (pollution from steel factories, uses resources). Automation can be  dangerous (the use of machines can jeopardize a workers life if they get hit by a robotic arm).  

These robotic arms are enclosed  in "CAGES" to prevent "accidents".

Steel

Steel is a alloy made of Iron and Carbon (0.5%-1.5%) and is widely used in the construction and infrastructure because of its high tensile strength and inexpensive cost. Tensile strength measures the breaking point of a material while being pulled or stretched. Steel mills add carbon to the iron to make it stronger; this occurs because the iron molecules can not move around as much when force is applied because it is locked together by carbon atoms. Steel used to be made in bloomery furnaces for thousands of years, however the process was not efficient and until the 19 century steel was mass produced because of the Bessemer furnace. However, currently Bessemer method is not used to commercial manufacture steel because the new method that is used makes it 10 times faster than the Bessemer method.

The current method used in manufacturing steel uses a basic oxygen furnace to create steel. First, high purity oxygen blows through the molten pig iron, lowering the amount of  silicon and magnesium compounds. Then they add cleaning agents called fluxes to reduce the sulfur and phosphorus levels.

Oil Refinery (Industrial Series)

An oil Refinery is a factory that converts Crude Oil into gasoline and a bunch of other compounds currently necessary for our modern life. A typical large refinery runs 365 days per year, employs thousands of workers, and can occupy 4000 acres of land. Modern refineries turn more than half a barrel of crude oil into gasoline and 70 years ago it was one-forth. In order to transform crude into gasoline, you have to separate it into various chemical compounds, Then they turn these compounds into Hydro Carbons and finally they add chemicals to the hydro carbons to create a vast array of products.


Separation: The crude oil gets pumped through furnaces causing it to vaporize and rise through distillation towers. The different compounds that make up crude oil are split up when they become the vapor. Since they have different boiling points and densities, the lightest compounds rise to the top and the medium weight vapors like kerosene and diesel hang around in the middle, and the heaviest compounds like residuum are at the bottom. The different compounds are already separated and sorted, so a vast array of pipes and valves collect the different compounds in the distillation towers and send them to the treatment refinery.

Conversion: The separated chemical compounds from the distillation units are transformed into intermediate components. This turns low value compounds into quality gasoline. The process uses a 1000 degree F furnace and catalysts to convert heavy elements into gasoline. The intense heat and catalysts are needed to speed up an help the chemical reaction because they break down the Hydro Carbon chains (catalytic cracking). In addition, the catalyst allows intermediate compounds to form, creating a reaction with a lower Activation energy needed.

Treatment: This is the final step before the oil gets sent off in tankers and ships. Chemists add chemicals to make the oil high performance or make sure it meets government and customer standards.

Frog (Ecology Series)

Frogs are a group of mostly carnivorous tailless amphibians and have been around at least 275,000,000 years ago. Astonishingly, the oldest frog fossil ever discovered is believed to have existed in the Permian period (before the Triassic period) due to molecular dating. The habitats of frogs are across the globe, deserts to rain forests  to subarctic regions like Alaska and Siberia. In addition, when temperatures get below freezing and ice crystals try to form beneath their skin and in their organs, some frogs survive! Amazingly, they can make antifreeze and use it to prevent the freezing of their organs. Actually, a frozen frog will stop breathing and it's heart will stop beating, clinically dead. However, when the temperature rises above freezing, the heart and lungs resume activity and the frog becomes alive, according to scientific american.org. These frogs are able to survive because the brain becomes dormant (no brain waves), there organs shrivel up releasing the water so that the cells don't die from being frozen, and they make antifreeze.

Turtles (Ecology series)

Turtles are are in the Animalia family and are classified by a unique cartilaginous shell from their ribs which acts as a effective shield. The earliest known turtles have been around since 200,000,000 years ago making the genius older than snakes, lizards, and crocodiles. Unfortunately, out of the 327 species currently alive many species of turtles are endangered, therefore you should attempt to protect them by participating in conservation organizations. Turtles are amniotes, which means that they do not lay eggs underwater. The difference between tortoise, and terrapin (types of turtles)is that a tortoise is a land chelonians and a terrapin (Algonquian word for turtle) is usually found in brackish waters.

The largest turtles known to exist today is the leather back sea turtle which can heave a length of  about 7 ft weight over 2000 pounds. Unfortunately, many species of Giant Tortoises which used to be around the world in prehistoric times had become extinct at the same time of the appearance of man. However, there are still a few living on the Galapagos island and can grow over 4 ft in length and weight about 700 pounds.


FUN FACTS

* turtles used to not be able to fold their necks in
* it is believed that turtles have excellent night vision due to the a high population of rod cells.
* Turtles used to have teeth which was lost millions of years ago. Now they have horny ridges on their jaws.
*Many studies have shown that turtles are better than white rats at learning to navigate through mazes. Also turtles are social animals and they rarely make screeching/high pitch calls.Studies show that turtles play with each other and enjoy it,
*Turtles have to surface and refill their lungs with oxygen. However, they can take up dissolved oxygen from the water, but only to a certain degree before they have to resurface for air.
*Temperture determine the gender of the turtle. Lower=male, Higher=Female

How to guide to Efficiency and Conservation part 1 (Technology series)

Efficiency is essentially getting the same bang for less buck. You can purchase ENERGY STAR  appliances and other electronic devices instead of buying conventional ones which would save electricity lowering your electric bill and CO2 emissions. Surprisingly the average family releases 28,000 pounds of Carbon per year which combines with oxygen creating 100,000 pounds of CO2 per year and this could be drastically lowered by using energy efficient devices. In addition, instead of buying tons of natural gas to heat your water, you can install a solar water heater to assist or replace your gas water heater. The physics be-hing them is very simple, sun hits a panel containing metal pipes which absorb the energy, Since heat travels from hot to cold, the hot pipes transfer their thermal energy to the water, thus heating it. Furthermore, you can install solar-panels on your roof, Surprisingly, if every person in the world had a few square yards of solar panels you could power the world.

Technology Series (Motors and Generators)

Motors and generators are fundamental in electronics. The principle behind them was discovered by Michael Faraday's in his laws of Induction. Even thought, he had shown continuous magnetic rotation by putting an magnetic wire in an electromagnetic field; Barlow had invented the first device powered by electromagnetism. In 1849, the three phase induction motor was invented which is still used today because it is the most efficient.

Motors and generators are astonishingly the same electronic device. A motor run backwards gives you a generator and a generator run backwards is a motor. For example, if you rotate the axle on an motor it produces electricity and if you run electricity into a generator the axle starts spinning ,giving you a motor. These devices work because of the induction law, which predicts how electromagnetic fields interact with an electric circuit producing EMF (measured in Volts). This states that a moving coil of wire around a magnet generates electricity. Also in terms of a motor an electromagnet gets repelled by other magnets causing it to rotate which turns an axle.

Photo from Recording "Little Child" with the Cars Greg Hawks (center)

Just Recently, my dad had finished composing a cool CD, Pavlov's Chalkboard. He has a professional recording studio with state of the art equipment and software for recording. He enjoys composing music as a hobby and he finds it relaxing and soothing to play after he has a busy day at his job. In one of the songs, Little child I had performed the vocals. The vocals may sound unrefined and absurd but that is up for debate. It is entertaining to listen to Greg Hawks from the well known band, The Cars, play flute, keyboard, and base guitar on the song.

Below is the link you can listen to the songs and hopefully you would enjoy snippets of it. And don't forget to give me a thumb up if you like it.
