First Floating Wind Turbine in Atlantic Ocean

An inspiring step forward in offshore wind energy technology

A Seattle-based company named Principle Power has deployed it's first floating offshore wind turbine off the coast of Portugal, the first time a floating turbine has been installed in the Atlantic Ocean.
Renewable Energy World reports the 2 MW turbine was assembled on land and then towed 217 miles into open water.

Car vs Bike

This neat demonstration clearly show the difference between the parking space occupied by a car and a bike.

It's an ironic step with an important message associated with it. Cars cause pollution and congestion ( both on and off the road ).

The bicycle stand shown ( practical implemented in some parts of east London ), occupies a space the size of one car and holds approximately 10 bicycles. This demonstration is clear enough to make you understand the difference.

Millions saved by Bicycling

"Biking instead of driving can save millions in health costs and thousands of lives"

The Modern Life style that we all are living today is driving us away from physical activities and making us more and more machine dependent.We all prefer using vehicles for cummuting even the smallest of the distances to our offices /  neighbors. Looking at the positive side we are saving our precious time ( a few minutes though ) but on the other side we are loosing a much valuable asset..i.e our own physical health. Now both time & health are important to us, how to save both of them ? So, here's the solution - "Bicycle"

Ok, Compared to driving, bicycling is clearly better for the environment and your health. But how much better is it?

Studies offers following figures: If people in the upper Midwest (northern portion of the U.S.) chose to take half of their daily car trips by bicycle, health care costs would go down by approximately $7 billion. And, it will also lead to an estimated 1,100 fewer deaths each year.

To an average, everyday common person -

 "switching from a car to a bike is an enormously healthy thing to do,And you not only get all those personal benefits, you improve air quality and reduce traffic on roads, and those are good ways of going green"

Inspiring Green Wonders

Bahrain World Trade Center 

Apart from the Architecture, the most impressive feature of this Center is the three massive wind turbines situated between the two towers comprising the main building. Each of these 80-foot turbines projects from a bridge between towers. The shape of the towers themselves channels and accelerates air moving between them which will help the building generate even more power.

It is by far the largest wind-powered design incorporated into a massive building project till date.

Solar Tower, Seville

Well, it is Europe’s first commercial power station to harness the energy of the sun. How does it work? The sun’s rays are all directed at a single point of the tower and turn water at that point into steam.

The steam in turn moves through turbines and generates energy. A strange but very functional process.

  Lighthouse skyscraper ,Dubai

The Lighthouse skyscraper  is another innovative green skyscraper to be constructed in Dubai. For energy generation, it will have three enormous 225 kilowatt wind turbines (29 meters in diameter), and 4000 photovoltaic panels on the south facing façade. To optimize performance and operational periods, the turbines have windward directional wind vanes or limited yaw.

Carbon Credits

What is it ?
Carbon credits are a highly regulated medium of exchange used to 'offset', or neutralize, carbon dioxide emissions.

 image-source = http://www.theseminargroup.net/images/small_logos/10.CARBOR.jpg

A single carbon credit generally represents the right to emit one metric ton of carbon dioxide or the equivalent mass of another greenhouse gas.

Larger companies, governments and other entities may be required by law to purchase carbon credits in order to emit greenhouse gases. This in some sense sets a limit on the amount of pollution a company is allowed to emit within a period of time. If the company stays under the limit, it can sell the remainder of its carbon credits to other companies.


Relation with Carbon Emission

"If you emit more , you have to spend more on purchase of carbon-credits"


In the case of mandatory carbon credits, the goal of placing a value on carbon emissions is to induce carbon credit purchases to choose less carbon-intensive activities.


Reducing the amount of emission leads to saving the amount of carbon credits. Companies that emit less enjoy higher profits by selling their rights to produce carbon dioxide emissions (carbon-credits). The saved credits can be sold to others and in this way they serve the purpose (everybody will obviously like to reduce the emission so that he need not purchase the carbon-credits ) 
This way, emissions become just as integral a cost of doing business as materials.


Where does the money spent for purchase of carbon-credits goes ?

 In the voluntary market, carbon offsets are used to fund projects which absorb or eliminate an amount of carbon dioxide gas that is equal to the amount emitted.
When consumers purchase carbon credits from reputable carbon offset providers, the money is used for specified projects like planting forests, which absorb carbon naturally, or diverting methane gas for conversion into electricity at a power plant.

Mobile Safety

The increased use of cell phones has brought about serious concerns regarding the probable health hazards. This is because mobile phones use electromagnetic radiation in the microwave range. 

Following Images show heat generated on the face by            
15 minutes of cell phone use due to their electromagnetic 

radiation

When radiation hits the head, it penetrates the skull. The pictures above are the result of an experiment show how radiation penetrates the skull of an adult (25%), 10 year old (50%) and a 5 year old (75%). The younger the child the deeper the penetration due to the fact their skulls are thinner and their brains contain more fluid than adults’. Radio frequencies travel through children’s brains much more easily and therefore increase the risk of cancer.

Tips For Use Of Mobile Phones

It is not only the choice of phone, but how you use it that is important when you want to control the amount of radiation you are exposed to. Here you will find a few simple tips that can considerably 

reduce radiation and therefore also health risks.

1. Use a handsfree set

The further away from your body the phone is, the less radiation you are exposed to. Using a hands-free set is the easiest way to radically reduce the amount of radiation you are exposed to if you use a mobile phone.

2. Hold it at the bottom

By covering large areas of the phone with your hand, you reduce its ability to send and receive signals. The phone then increases its power and transmits stronger radiation to compensate this. So hold the phone as far down as possible, so it can operate at low power. 

4. Get in the best position

You can see the signal reception strength in the display. When reception is good, the phone reduces power and radiation. If reception is poor, the phone uses maximum power and radiation.

5. Don’t talk too long and Use regular phone if possible 
The radiation you are exposed to is directly related to the time you spend talking on your phone For longer calls it is safer “and cheaper” to call from a regular phone.

6. Hazardous areas of use

• Don’t use a mobile phone while driving a car. Stop at a safe place and talk.
• Don’t use your mobile phone in places where there is a lot of electrical equipment, such as hospitals and aircraft.
• Don’t bathe with your mobile phone.
• Don’t let small children talk on your mobile phone for long periods. They are more susceptible t than adults.

The Federal Communications Commission sets specific absorption rate “SAR” standard ( Specific Absorption Rate )  which is acceptable power radiation for cell phones must not exceed 1.6 W/KG The lower the SAR the better the phone, from a potential health hazard.

There are three way to know the SAR

1. From the user manual of your mobile phone.

2. Visit mobile manufacturers forum web site and select your mobile phone model

3 .Enter Federal Communications Commission website and Write your mobile FCC ID Number in the 

FCC ID http://www.fcc.gov/oet/ea/fccid/
