“Energy”, don’t know how many times we use this word, but we surely use energy everyday. By now, we know what renewable energy sources are( if not go ahead and click here Renewable).
One of the most effective renewable sources of energy is wind energy, till now we have seen only the windmills on the ground producing energy. But, here are the new ones that are situated above the ground so called “Flying Windmills”.
So, what is the reason to put the windmills above the ground? Well… Higher altitudes offer upto five times stronger winds that are also consistent.
This thing flies with the help of helium filled shell. The airborne wind turbine will be held steady by making use of strong tethers which will also transfer the electricity generated to ground. And Flying windmills are actually tested!
Ben Glass, is the one who came with this idea. Learn more about these flying windmills from the video below.
All the projects that Google is working on, like Project Ara, Project fi, Project Soli, Project wing, Project balloon, Project Tango and many more are super cool.
In my view this year Google I/O 2016 was mostly about AI and VR. Last year I have read about “Google Project Ara” and that really freaked me out. Now let’s see what actually is Project Ara.
Google Project Ara wants to do to hardware what apps did to software.
By creating a phone that can have each component changed, all the main components are interchangeable via modules that click in and out, attaching via electro permanent magnets.
Google believes it will drive down hardware pricing while allowing users to pick and choose what they want. That’s what Google’s Project Ara a modular smartphone aims to do. No need to buy a new Smartphone due to some damage just change the respective module. At last we can say only one thing that it’s a flexible platform suitable for everyone, everywhere and any time. It allows developers to be able to create modules for its Ara device.
Smart tools are everywhere now. Likewise many manufacturers are diving into the development of Augmented reality( learn more about augmented reality and VR here VR vs AR )Even BMW is working on something related to augmented reality, motorcycle helmets that let drivers keep tabs on their gas levels and RPMs without glancing down from the road. The helmet also features front and rear cameras.
Some rare fighter pilots have been using augmented reality built into their helmets for years to keep an eye on the plane’s gauges, monitors, and weapons systems without having to look down. Now that technology is coming to motorcycle riders, with BMW and DigiLens.
We may argue that, displaying some info on the screen doesn’t make it augmented reality, but DigiLens does manage to drop a layer over the rider’s view that enhances real world road environments.
The helmet’s functions are actuated with controls on the left handlebar (which is good, because mucking with controls on the helmet itself while riding could get a little messy). It also has a forward-facing action cam that can record your ride, and a rear-facing camera that can be used as a virtual rear-view mirror in the heads-up display. The system is powered by removable batteries that are good for a claimed five hours of life.
A quick reminder, this is kinda similar to Google glass!! And some sources says that BMW is also working on some innovative cars which use augmented reality.
All these developments, in installing new technologies in various unique tools is due to INTERNET OF THINGS, which brings various indifferent things under a common roof so called Internet. Learn more about INTERNET OF THINGS here Internet of things.
We’re swimming in a sea of electromagnetic radiation produced by electrical appliances and other technologies everyday, that are part of modern life.
Your phone sends radiofrequency, or RF, waves from its antenna to nearby cell towers, and receives RF waves to its antenna from cell towers when you make a call or text or use data. The frequency of a cell phone’s RF waves falls between those emitted by FM radios and those from microwave ovens, all of which are considered “non-ionizing” forms of radiation.
That means that unlike radiation from a nuclear explosion, the radiation from your phone does not carry enough energy to directly break or alter your DNA, which is one way that cancer can occur. FM radios and microwaves don’t harm us because they aren’t held close to your head when in use and because microwave ovens have shielding that offers protection.
Many studies were done and the results were not accurate. As of now there are more mobile phones than the total humans on our planet, which means the rate of tumour should increase as the cell phones are increasing, but it isn’t.
In astronomy, we often hear the word “Supernova”. Let’s see, what actually a Supernova is?
Supernova is an event where an explosion of a huge star takes place. These blasts produce some heavy material in the universe including some elements, like iron, which make up planets. Not all stars become Supernova though.
So, there are two types of supernovae.
White Dwarfs is something with the size of our earth and with 8 times the mass of our sun. This explains how dense it is. With this high density, it pulls mass from the neighbouring mass, using its gravity. By taking in the mass, it reaches a level called “Chandrasekhar limit”. At this instant, the star becomes unstable and supernova takes place. In turn, it forms something called Neutron star.
It occurs when stars core’s fusion process runs out of fuel. They can briefly outshine entire galaxies and radiate more energy than our sun will, in its entire lifetime. Stars are high nuclear reactors producing energy by fusing hydrogen into helium. Running out of fuel is nothing but, running out of hydrogen. With this, the helium is fused into heavier elements and supernova takes place, adding enrich elements to space clouds of dust and gas, further interstellar diversity, and produce a shock wave that compresses clouds of gas to aid new star formation.
Ultimately these supernovae are responsible for Black-holes and Birth of new stars too…
For so long, scientists were trying hard to find the evidence for Gravitational waves, predicted by Einstein over a 100 years ago, in his “Theory of Relativity”. Finally, scientists at LIGO( Laser Interferometer Gravitational Waves Observatory) detected Gravitational Waves.
Scientists estimate, about 1.3 billion years ago, two black holes collided at half the speed of light. Which resulted in Gravitational waves. Detector at LIGO detected these waves.
LIGO has two identical detectors, one located in Livingston, Louisiana, the other in Hanford, Washington. These Detectors can detect even very little vibrations from Gravitational Waves.
You might be knowing the Flash. For those who don’t know Flash, Flash is a DC Comics character with super speed. So much speed that he can travel in space and time( back and forth in time). Which means at the speed of light!!
The Flash could not realistically do what he does. Let’s see what we need, to do what he does.. To move at such greater speeds, we need energy, for which we need to eat at super speed too!!!
At such greater speeds there is something called air resistance. Just try running on a windy day in the opposite direction to the wind, you will know what I am talking about. With this air resistance we may be on fire, because of the friction between the air and our body, once we achieve higher speeds.
Well… Writers are clever enough to introduce something called force field to explain this, which The Flash gets through a failed experiment( particular accelerator).
In recent articles, we have learned that, even light takes some time to do things. Which means, to see things around, light should travel from the object to the eye, from the eye to the brain, then our brain processes that information and finally we actually know what’s going on. Seems that when we look our self in a mirror, we actually are looking at a few nano seconds past image.
We see the world in maybe 60 fps (frames per second), which we think is really present. Some animals see the world in 240 fps and I can’t imagine, how flash see the world. Maybe, in his perspective the world is paused.
Electricity is very essential and the resources to produce electricity are limited. Also, most of the energy resources we use to create energy are non-renewable and harmful for the environment.
In such scenario, creating energy through gravity is extremely useful and innovative. A weighted bag is hung and winched (a pulling device, which pulls) up. With this the weighed bag descends down gradually.
It uses this weight to drive a gear-train and generate electricity from the kinetic energy created, sufficient to light up an LED bulb.
This really helps people in rural areas with lack of electricity to light up their houses using nothing but “Gravity”. This is more efficient than solar energy.
Time dilation leads us to time travel!! Sounds great, but kinda weird to explain. Your concept of relative speeds doesn’t work here.
If you and superman are flying with the same speed, then with respect to you, the superman is at rest. This isn’t the case with light, as long as your speed is less than light( though your speed is so close to light), the speed of light doesn’t change with respect to you.
If speed isn’t changing with respect to you, though you are moving, then what is changing? Well… The time is changing. So, this is the key for time travel.
Have you watched the movie “Interstellar”? Yeah you must. When the hero returns to his daughter from another planet probably in other solar system, his daughter becomes more than 90 years old( that is much older than her father). This is time dilation, because of his journey through wormhole.
You could do a flyby of a nearby star and return to Earth at nearly the speed of light, and a few years would pass on Earth while possibly only a few weeks or months would pass for you, depending on how fast you were going and how far away the star was.
Few of my recent articles are related to this one. RELATIVITY (all about the Einstein’s special and general relativity) and the previous one Stars ( which proves that, even light with such great speed takes “Time” to reach us;)
There is another extension to this article, can you guess one?
