To see the enormous strength of steam, you do not have to search further than witnessing the eruption of geysers or the explosion of gasses that occurs when lava mix with oceans. Man has witnessed such sights and for long tried to control the crude power of steam using technology ranging from the tea kettle to the modern nuclear power plant. Regardless of the level of technology involved, steam power comes down to one basic principle: When water is heated to point of vaporization, the vaporized water occupies more space than the liquid water.This is because solids, liquids and gases are each binded together by different strength of inter molecular forces . In solids,the molecules are compacted together. In liquids, they have more spaces apart. And in gases,such as steam, they are further apart. If  a can of soup is heated on  fire, the contents will turn to vapour and later expand ,making the can explode to let out the pressure within.If this pressure is taken to perform work,

Have you been to an  airport  recently, you must have seen that air travel is increasingly being congested. In spite of numerous delays and flight cancellation, airplanes  are still the fastest means to travel several miles in a short time. Passenger air travel changed the transportation industry completely in the last century, allowing people move through large distances in hours instead of days or weeks or months. The option to airplanes  - feet, cars, buses, boats and old trains - are seriously too slow for today's fast-paced world. There is a new means of transportation that can completely change transportation of the 21st century the way aeroplanes did in the 20th century. Some countries are using very powerful  electromagnets  to produce very high-speed trains, known as Maglev  trains .  Maglev is shortened form for magnetic levitation meaning that these trains float on top a guideway employing the basic principles of magnetism to replace the archaic steel wheel and

It is believed that a lot of people are hooked to the  Internet   ,but this is only partially true. Around 4 billion people do not have access to the internet as of late 2015. Several people reside in place where there is no internet infrastructure,or where coverage is unavailable or exorbitantly high. Google, known for its numerous high-tech pursuits,has several projects in the development stage to bring high-speed Internet access to the a lot of people. Their Fiber project aims to provide Gigabit internet service,which faster than the existing connection speeds we are used to. Using fiber optics,it has programs going on in several cities in the US. The firm has a different project focused on taking high-speed Internet access to places that do not have it. The project uses a technology we call it primitive — balloons! The project is known as Project Loon ,because it involves using  balloons  and also because it sounds looney. Google intends to create wireless networks using equ
