What is Radio waves?
Radio waves: The longest wavelengths with lowest frequency
Q: What it the electromagnetic spectrum?
A: The Electromagnetic spectrum or EM spectrum is the vast range of all different types of electromagnetic radiation. The EM waves have the same vibrations but at a different frequencies.
Here are the graphical representation:
.gif)
Q: What is the historical discovery?
A:
In 1864, a Scottish theoretical physicist and mathematician James Clerk Maxwell (June 13,1831- November,1879) established the famous equations that bear his name and include the laws of electrostatics and magnetism.
Maxwell's Law of Unification
In 1886, a German Physicist, Heinrich Rudolph Hertz demonstrated the existence of radio waves.
Here are Hertz Equation:
Frequency = (wave speed in m/s) / wavelength λ in m) or f = c / λ
Time = 1 / Frequency or T = 1 / f
The unit hertz (Hz) was once called cps = cycle per second

Wireless charging
Wireless Energy: The Next Big Thing
The concept of wireless energy has been here for a long time. Starting with the pioneer himself, Nicola Tesla. Tesla was an inventor, futurist, physicist, electrical engineer, mechanical engineer, who was best known for the major contributions in developing the modern alternating current(AC) supply system.
This concept becomes the center of research for big companies and independent researchers.
The question is how can we transmit electricity(charging an electronic devices) without using any form of wires? Is wireless Energy a theory or a futuristic concept?
Well, let us answer some questions and get deep into the discussion to find out.

Definition:
Electricity is the flow of electron. That 's it! You should know that the electricity that we used every day is a second source of energy. Note that the transformation of the first source of energy such as coal, solar energy and other produce electricity.
By convention, there are two type of charges: a positive charge and negative charge.
case1: two positive charges or two negative charges repel each other.
case2: A positive and negative charge attract each other.
See figure below:
Thomas Alva Edison is considered as the greatest electrical engineer of all time.
He is the father of the DC current which was used by sending electricity over wires and it was the common from of electricity transmission. Cities were power/light up using Direct Current by 1890's.
In 1879, Thomas Edison (1847 - 1931)
invented the first practical long-lasting light bulb(using a small carbonize filament, and vacuum) which used DC(Direct Current) current.
The world was amazed by his invention, which include some other inventions such, foil phonograph(by 1877), motion picture camera which was tested by 1891.
Edison is considered has the greatest electrical engineer of all time not only by his invention but by its imagination, creativity, ambition, perseverance, determination of building tools that helped the world.
The cylinder phonograph, for example was the first machine that could record and reproduce sound.
He mentioned that: "I want to see a Phonograph in every American Home."
During this years, Nikola Tesla (1856 - 1943) a young Serbian-American scientist and ambitious engineer was working for Thomas Edison who was fascinated by another source of energy calls: alternative current or AC electrical system.
Tesla believed that one day, the world will be connected by wires using AC.
He is currently considered as the person who develop the concept of alternative current. Some of his invention included, wireless transmission, radio, fluorescent lighting, the Tesla coil transformer and more...

Q: What is AC(alternative current)? and how does it work?
A:
The phenomenon of alternative current shows that electricity which is a flow of electrons in a conductor can periodically reverse their direction of movement. For example, radio station produce alternative current(through waves) which can be tune in low to high frequency.
AC; alternative means (change of direction) and current means (flow of electrons in a conductor).
Tesla believe that electricity could be transmitted through wires at varying current through transformers which he developed.
So, A source of alternative current or voltage is required to produce/supply an alternative current to a circuit. A typical example will be a coil of wire rotating with a constant angular velocity in a magnetic field.
An alternative current varies with time which produces a waveform or sine wave. There are different types of alternative current waveform.
- Sine wave
- Square wave
- Saw tooth wave
- Triangular wave
- Ram wave
Q: How can we transmit electricity(charging a electronic devices) without using any form of wires? Is wireless Energy a theory or a futuristic concept?
A:
We love electricity and we used electricity everywhere, everyday at an exponential rate.
We need to power our electrical appliance such, TV, Refrigerator, Ipad, phones, DVD player, computers etc... Note that, all these machines have one thing in common: WIRE, yep wire cords. That's sucks, why? Imagine you have to power 10 appliances at once, well you will need a 10 wire wall plug, this is very overwhelming and suck..lol.
Well, we used wireless energy everyday though. Phones, radio, WiFi signals, received and send data or signals ( radio wave).These devices using radio waves communication.
Radio waves transmission is great for transmitted information but not suitable for power transmission.
The major problem of radio waves transmission is that they can become slow when more connection occurs.
The problem of noise and the lower the frequency of the wave, the less it can transmit.
However, how can we tackle this issue of wire cords. Imagine a world without wire, a world where you never have to power you devices with a single wire. This sound too good to be true. lol!
Well, this futuristic concept/idea is now a reality. how?
In 2007, Thanks to a group of theoretical physicists, engineers at MIT(Massachusetts Institute of Technology) invented a new way of transmitting electricity WITHOUT using any form of wire cord. Amazing and exciting! They call it: WiTricity.
They were able to charge a 60 Watts light bulb from a power source located 7 feet(~2 meters) away. This connection was done without any wire between the power source and the device. Nice work huh!
The concept of WiTricity is based on resonance energy transfer..

Q: What are transformers?
A:
A transformer is an apparatus for increasing or reducing the voltage of an electric power supply to allow device to be connected.
Inside the transformer there are two coils of wire or winding that are close to each other and that actually transmit energy wirelessly through magnetic field in a very short distance. The core of the transformers are made of conducting material such, iron with a very large relative permeability. The constant(relative permeability) keeps the magnetic fields lines concentrated in the core. Note, that for safety reason, magnetic fields are safe to use.
However, MIT researchers team worked on: magnetic couple resonance. They find that, it exists a stronger coupling force between two electromagnetic coupled resonators. The first coil is connected to the power source for energy transmission which energy will be transmit at higher frequency. The second coil( the receiver) resonate with the field(at same frequency as the first) which establishes a connection between the two coils(that will allow transfer of magnetic field). So basically, an ac source causes an alternating current in the sending coil which create an alternative flux within the coils. This will allow a voltage to be induced in each winding or coils. Though, in the receiver coil, the induced voltage create an alternating current in the second winding which then can power any devices connected to it. The MIT team was able to separate this coil from the transformers into a great range distance that will allow them to charge the 60 watts light bulb.

Q: What about safety issues?
A:
The magnetic field do not radiate and stay in close surface within the device or in short distance.
There are very safe for humans to use them. The system only use Magnetic field not Electric field which radiate.
Conclusion:
Note that this transfer of electricity(AC)) can only be done in a short distance.
Nevertheless, we can now say that there is possibility to charge at a very short distance an light bulb. So, in a future, we will be able to have one device that will automatically charged all our electronics devices when they need it. Life will be much easier for me and you probably.
Finally, we can say that wireless energy is not a futuristic concept anymore. Wireless energy is not a imagination but a reality. I believe one day soon, I would be able to charged all my electronics wiressly, without have to be worry to look for a plug. Perhaps, one day, this system will be efficient to power not only in short distance but in long distance.
From electrical cars, to home appliances, from mobile devices to medical devices, this concept will change the way we use electricity by making it simpler and safer.

Solar energy
Solar Energy: The Importance of the Sun
Companies and private researchers around the world are studying the ways to make this process more efficient. In this case, we are taking a look at two layers of silicon for test study.
Q:What you should know about the sun?
Q:What is solar energy and what is the process that transforms the sunlight into an usable source of energy?
Q:How will it impact the future?
Let us answer some questions...
Q:What you should know about the sun!
A:
The sun is a spherical star located in the center of the solar system. It's gravitational pull/force (Heliosphere) produces an enormous pressure and temperature which allows all planets to rotate around it. Mostly composed of gases (charges particles ionized, called plasma) that are converted into a huge amount of energy (nuclear fusion) in the sun's core. The energy is radiated/rejected slowly from its core to its surface (outer layer) which is then release into the solar system as radiation/heat and light/charges particles. This process can takes millions of years.
The sun is composed of multiple layers (6 layers). Each layer has its unique physical properties.
Thus, in the core, hydrogen atoms fused to form helium at a temperature approximateley equal to 15 millions degree Celsius. The second layer is called Radiation zone where energy released at the sun's core will radiate. It will take almost 100,000 years for a photon (massless energy) to leave/travel this dense region and arrive in the region called Convective Zone. In the convective zone, it will take about 30 days for a photon to travel the region and enter the subsurface flows. The photon will continue its journey into the photosphere ( the surface from which the solar light is emitted or radiated) and finally arrive to chromosphere ( a layer above the photosphere). Photon will continue to travel into the corona , a layer of the sun above the chromosphere which expands into the sun's surface.
Facts: It takes sunlight an average time of 8 minutes and 20 seconds to travel from the Sun to the Earth.
Speed of light: 3.0E8m/s
Age: 4.57 billion years
Core temperature: 27 million degrees F or 15 million degrees Celcius
Radius: 695,500 Km

Q:What is solar energy and what is the process that transforms the sunlight into an usable source of energy?
A:
Solar Energy is the process that transforms the sun's light into a collectible and usable energy. Looking at sun power, its energy can be used to power every home on earth, cars, streetlights, calculators, and more. It is an amazing fact!
The sun releases an energy from its core in form of electromagnetic radiation ( waves or tiny charges particles). This energy gets captured ( by solar panels) , and converted into
electricity using photo voltaic cells.
.gif)
What is a photo voltaic cells?
Photo ("light") voltaic ("electricity") is a process that converts photons into Electrons hence converts sunlight into direct current (DC) electricity.
What is an inverter ?
An inverter simply converts the DC (current) into an AC (current) that is used to power the entire house.
A solar panel contains two layers of silicon (on top: phosphorus-doped, on bottom: boron-doped) that allow electrons to flow and conduct electricity between them. The flow of electron is possible because of the metal conductor strips.
How to set up the cell to receive the sun light?
Note that the there is no transfer of electrons without first established an electric field.
The phosphorus-doped layer contains extra electrons (negative charge) which will be transfered to the boron-doped layer that has less electrons. After the transfer, the boron will be negatively charged the phosphorus layer will be positive.
How the electricity is generated?
When the sunlight light (photons) reach the top of layer, electrons are excited and moving freely in both silicon layers. At this point, an electric field gets established and electrons get released out of the top of the silicon layer (metal conductor strips) where electricity is being produced.
How electrons flow?
Electrons flow through wires into specific destination (house) where they are used to power electrical components and then they flow back to the cell through the cell's metal backing. This electricity produced by the cell is then absorbed/store by the silicon layer which ensure the particles of sunlight (photons) do not get reflected (anti-reflective coating) through the process. The anti-reflective coating is very important because it keeps the alternative current flowing in back and fourth.
NOTE:
The electricity generated by the solar panel can run out depending on how much the sunlight is received. However, note that your house will need to be connected to any other source of power when your not using the solar panels, the power grid. Hence you are still connected to the utility grid (convention electricity) and this will make sure that you can always use electricity in case of raining day, night, very cloudy day etc...

Solar Energy is one the most unused energy sources today! This technology is still being improved to make it more efficient and cost effective. I believe that solar panels will be vital in the future and solar energy will power most of our electric machines from buildings to cars as well as key chains, public traffic lights, etc. In the future years it will become more affordable and attainable to average consumer making it the primary energy source !

3d printer - the future of printing technology
3D printer: Future of Printing!
3D printing is here,companies are presenting some of their latest inventions! These inventions are being constantly improved. Thus, while others are trying to understand 3D printing, some are even thinking deeper in the printing world! I am talking about 4D printing! Yep 4D printing..
Well, before going further we need to get some questions answered!
What is 3D(dimensions) space?
How does 3D printing started?
How does 3D printing started?
What is 3D printing?
How does 3D printing work?
How much it cost?
How will it impact the future?
Q:What is 3D(dimensions) space?
A: In mathematics, Three-dimensional space is refer in (X,Y,Z) coordinates. Note that the world we live in, the physical universe is constituted of 4 dimensional space including the parameter t refering to time. What we see everyday is in 4D...
Q: How does 3D printing started?
A:The idea of 3D printing started in 1990s , a manufacturer used RP (rapid prototyping) to build a prototype for testing that was used to produce the final product. As a result the product was created faster and easier.During 1990s, MIT (Massachusetts Institute of Technology) and a company 3D Systems were the earliest developers of 3D printing technologies. In addition to MIT and 3D Systems, some other companies such as Stratasys, Hewlett-Packard company, Autodesk, Dassault Systems SA, Exa corporation etc... have dominated the market with their 3D printing products.

Q: What is 3D printing?
A: 3D printing is the process of creating three-dimensional solid object from a digital model . The process used in making a three-dimensional solid object is additive process.
Basically, it is a machine that can make a copy of anything in 3D, very cool.
Printing in 3D is done by building layer by layer of an digital object.

Q:How does 3D printing work?
A: 3D printing system can be a complex mechanism. Done with a computer aided design or with an animation modeling software, starting with a computer model to be printed . Once the model is done, it is send to a 3D printer using a specific language called: STL (Standard Tessellation Language or stereolithography). STL or Stereolithography is an additive manufacturing 3D printing technology used for producing advance models, patterns, prototypes and parts. The technology was developed by 3D systems corp.
Note that all 3D printing process are similar, these are the fundamental steps in which it takes to build physical object from the digital model:
1- First, CAD (computer aided design) or animation modeling software is used to build or to create a 3D model. 3D model is then analyzed before it gets send to the printer. After analysis is done, the CAD model gets converted into the STL format.
2- The transfer to AM (additive manufacturing) and STL File Manipulation, allows users to create
copies of the STL file to the computer that controls the 3D printer.
4-Now, the printer is active and doing its job. This job is done automatically. Depending
on size of the project, the printing process can take few hours up to days to be completed.
The printer builds the physical object layer by layer as close as 1/10 of mm.
Once the final object is done, it is removed from the printer and gets cleaned for inspections.
5-Excellent job! printer.
Printing in 3D can be more complicated than you think! Its all depends on your machine
and how user friendly it can be.

3- When the STL file is ready, the designer sends the file to the printer that will use a specific material such as rubber, plastics, laser, to build the object.

Q:How much it cost?
A: The prize of 3D printers can vary tremendously.
The expensive ones can cost up to $500,000.which are used in large companies for heavy duties.
However, average ones can varies from $1,000 to $100,000. The ones costing in range of $1,000 are mostly used to build small items such toys ,other small gadgets such as earrings, shoes, rules, sandals, glass etc..

In Fashion/ Furniture:
Some designers used the 3D technology to build cool 3D toys, such small electric cars, cup of tea, glass, folds, shoes, earings,etc..
In conclusion, 3D printer is the future and I believe that every home will have one.
3D printer might be expensive for average consumer but sooner or later the cost will drop making it affordable for an average home! Majority of homes will have one and will be able to print anything they want , I mean anything that will not go against the law.. hahaha.. example building a gun.
