# Solar powered Smartphones : Solar thin plate at back of the smartphone

What will be the impact on environment due to usage of smart phones ? how much energy they consume ? this might look silly because after all a smartphone how much it can consume ?

fine let us analyse the data …

An iPhone 6 plus battery spec is 2915 mAh battery (11.1 Wh), for your information 1Wh is a unit of energy equivalent to one watt (1 W) of power expended for one hour (1 h) of time.1 Wh represents 3600 joules of energy. Your iPhone uses 11.1Wh, now assuming you will charge your phone every day, so it means every year your phone consumes 4000Wh of energy per year.

now think about number of iPhone users , yeah here is the stats. Apple sold a whopping 74.4 million iPhones over the 90 day period. Which means 74400000 iPhones ( assuming all are iPhone 6 plus ). So the total amount of energy will be 1,97,60,00,00,000Wh.

A CFL bulb uses 767KWh per year, now converting 1,97,60,00,00,000Wh. to KWh gives us 29,76,00,000Wh

so using this much power we can use 389CFL bulbs for a year. Wait I am just considering iPhone 6 here.

We have Micromax,Samasung Galaxy series, HTC, Motorola etc.

Now let us take a look into total number of mobile phones used in the world 🙂

Its a huge number – so energy being used ???

# Why it is necessary to think about Solar Powered Smart phones ?

Considering the above stats it is really a good idea to think about keeping a solar plate attached to the back of your smart phone and completely avoid using electricity for charging. If you start using 3G you have charge your phone atleast two times in a day,  playing videos and games at least three-four times you have to charge in a day.

Let us look into few more stats – The below data is almost 3-4 years old

61% of smart phone subscriptions, 4221 Mega joules of energy which is equivalent to 32gallons of Gas and emits 112Kgs of CO2.

Transferring 1GBit of data over 3G network will use 933 Mega joules of energy, If every one left their cell phone charger plugged It would waste electricity enough to power 28000 homes.

Finally at Mobile World Congress in Barcelona, a prototype has been shown that uses a display as solar panel to charge the battery.

# Future Of Technology : Imagine the future

Where we are heading ? What will be the future ? The whole world is evolving just due to few big elephants, yeah Google,Apple,Facebook and Microsoft. Thousands of companies every day emerging out and directly or indirectly these big elephants are source for all these evolution in technology, they are changing the world.

We have seen great inventions happened in last decade, Everything which was there upon the table now came to your finger tips, you can speak to your mobile and yeah it responds you back nicely. Apple Siri changed the way of communication with its touch interface in iPhone and voice interface in Siri, google now and microsoft’s Cortana.

Microsoft took one step ahead with its Hologram that is one of the awesome idea, but how much that would be complete we have to see only when we get it in use. Google’s self driving car and now Apple in the same line.

What else ??

# An Era of Adopting to Technology

This is very old story now, 5 years before people use to say we should adopt technology, use technology and grow your business, use technology and optimise your tasks, use technology schedule your duty oh what not? It became big problem for old generation who never understood how to use computers and how to learn to use applications etc.

Observing closely the recent evolution in technology proves that, that era has gone now, it is taking a new shape and evolving even more sophisticatedly and smartly. then What we could expect out it ?

# An Era of Technology being adopted to humans

Does’t it looks funny ? or does it make any sense ? yes of course it makes sense. Softwares are becoming smart with the intelligent algorithms, devices are becoming smarter with ultimate sensors, It is not just your touch, it is not just your voice now your movements and pattern are being analysed by algorithms and your device decides what to do next ! Google Search becoming clever every day it can understand the context you are working and you can query as if you are speaking to some one. Apple announced latest OS, the main focus is to make their device intelligent, It understands where you are, it understands what you are looking for it suggests you.

Operating systems are becoming smarter day by day, the data you are going to access are local more native centric, machines knew what you want, they understand you better than any one else 🙂

# Future Is In Artificial intelligence ?

Looks like These big elephants are creating market for it, Apple’s HomeKit and google’s Brillo making every object you are using at home connected, your every device may start understanding what you are and they serve you what exactly you want and when exactly you want.

You home lock is connected to you phone, your kitchen is fully under your control, your lights will get on as you enter and off as you are leaving the room, algorithms understand your behaviour by analysing the data collected and will suggest you which food you can have now, they alerts you when you are eating high calorie food because your weight is under control since you started Yoga 🙂

# Future Of Robotics !

So far robots were made for space missions, for military and for research areas but its the time to have a robot for your personal assistance everything what a human can do, now machines can do much better than him, will be popular soon. Google is investing in robotics not only this much there are Top 10 Robotics companies which are expected to change the future of robotics.

# Automation Industry

Thanks to ipv6, you can generate as many ip addresses using ipv6 where you can automate each and every device of every home in the world, Thanks to the concept of Internet Of Things where every device is connected to cloud directly, google’s Brillo is an example for IoT. You automate everything, control everything just using your smart phone, yeah really smart phone 🙂

# Future Of Technology ?

One can imagine now what would be the future of Technology, Everything is connected, Everything under your control, Everything is automated, Everything is smart and intelligent, Everything just in front of your door. Rather than asking what you want, now your devices, your softwares will say what you need 🙂

# Imagine the Future !

Companies investing heavily to make your life simpler, but we are really neglecting the mother nature, we are really forgetting environmental issues, our soil is polluted due to waste gadgets, chemicals etc our air is polluted, oceans are polluted. globalisation bringing more and more problems to us. We should really encourage and appreciate the use of renewable energy sources and make our future even better.

Use of solar panel for you mobile to charge, use of solar power to make ur robot work at home, use of intelligent architecture to cool your home/office, what else can be done ? just invent anything keeping environment in mind.

Enjoy the future because you have no work to do, you will be the laziest animal on this planet 🙂

# MIT’s Robot can jump over hurdles : Cheetah robot

Human’s can achieve anything, human mind is the greatest gift of god. If you run in hurry or if you run on a moving floor your mind will get confused and some times you fell down. If you are not practiced then you can’t even cross two three hurdles continuously, you will fell down. Have you ever wondered a robot can do this ? it is so difficult to program even a simplest automation or even a simplest robot which can just move by itself. Now we have everything ready made so you may say it is not so difficult, but Cheetha which can run and jump over the hurdles ? really challenging.

# A MIT’s Cheetah Robotic TEAM

Deborah Ajilo, Negin Abdolrahim Poorheravi,John Patrick Mayo,Justin Cheung, Sangbae Kim, Shinsuk Park, Kathryn L. Evans, and Matt Angle.  Will Bosworth, Joao Luiz Almeida Souza Ramos, Sehyuk Yim, Albert Wang, Meng Yee Chuah, and Hae Won Park.

# Algorithm Behind MIT’s Cheetha robot :

The bounding algorithm which made this possible will program each of the robot’s legs to exert a certain amount of force in the split second during which it hits the ground, in order to maintain a given speed: In general, the faster the desired speed, the more force must be applied to propel the robot forward.

the cheetaha robot adopts the force as per the surface and hence it successfully passed the test in grassy area and treadmill.Robot can run 16 km/h, jump about 40 centimetres high, land safely and continue running for at least 15 minutes .

# Technical Details of MIT’s Bounding Algorithm and Robotic Cheetah

It took more than 5 years to achieve this and Cheetah 2 contains the custom electric motor designed by Jeffrey Lang, the Vitesse Professor of Electrical Engineering at MIT and the amplifier designed by David Otten, a principal research engineer in MIT’s Research Laboratory of Electronics.

“bounding algorithm” calculates the varying amounts of force required to propel an animal forward or to jump over obstacles. Algorithm models the running mechanics of world-class sprinters like Olympian Usain Bolt: the faster the desired speed, the greater the force the legs exert.

This robotic cheetah carries out its movements with the help of battery powered electric motors which do not make much noise even.  Though the US-military has been trying for several years to make a stealthy and fast robot, it hadn’t been successful until now so this DARPA funded research by the MIT researchers may just open a whole new vision regarding the making of a stealthier bot.

# Domain Name Server and Domain transfer

Normally what happens when you purchase a domain from one Vendor say Amazon, you will link the domain to you web hosting account.

But later you may stop using amazon hosting service but you find some other vendor for hosting. Say you go for squarebrothers.

In that case you will be having two options, either set your name servers to point them to your square brothers vps hosting account.

Let me briefly explain how exactly these domain names works

Assume that you purchased a domain knowledge.com in amazon. It looks like below

Which means amazon has dedicated three name servers to map your domain knowledge.com to system specific ip address. Everything in internet works with ip address, knowledge.com domain will be mapped to specific ip address but to translate an ip to human readable domain name name servers are required.

now your domain mapped to name servers of amazon, these name servers will be allocated for you when you purchase hosting account.

If you purchase an account in square brothers, they will provide few name servers for you, to map the domain knowledge.com which is there in amazon, you just need to set name servers of square brothers hosting account in amazon domain control panel.

Assume that square brothers have given ns.sqrbr.server1 and ns.sqrbr.server2 as name servers, set these to in amazon by replacing name servers given in the above fig.

This is just mapping domain name, in case if you want to transfer completely from one account to another you just need to disable privacy protection and theft protection in the closing account, and apply for domain transfer.

# From Neurons to Networks

I was just trying to understand how can I use a graph theory to understand or analyse human brain and connections within it. I found an interesting video here. It will ignite an interest within you and a new connections will be created in your brain as you start watching 🙂
