Technology to convert heat waste into electricity

Scientists have claimed a breakthrough in converting waste heat to electricity by developing a new thermoelectric material which they say is best in the world. The Northwestern University finding offers hope to tap the waste energy as nearly two-thirds of it is lost as heat. The material could signify a paradigm shift, as inefficiency of current thermoelectric materials has limited their commercial use.

With a very environmentally stable material that is expected to convert 15 to 20 per cent of waste heat to useful electricity, thermoelectric could see more widespread adoption by industry. Possible areas of application include the automobile industry, heavy manufacturing industries and places were large combustion engines operate continuously.
Waste heat temperatures in these areas can range from 400 to 600 degrees Celsius, the sweet spot for thermoelectric use. The new material, based on the common semiconductor lead telluride, is the most efficient thermoelectric material known.

It exhibits a thermoelectric figure of merit of 2.2, the highest reported to date. Chemists, physicists, material scientists and mechanical engineers at Northwestern and Michigan State University collaborated to develop the material. The performance of the new material is nearly 30 per cent more efficient than its predecesso

A Smart Bulb that is controlled by Mobile Phone

A group of young Australian inventors has given the humble bulb a snazzy upgrade. They have developed the worlds smartest light bulb that dims, changes color, strobes, switches on automatically, and can be fully controlled from a mobile phone. The inventors secured almost a million pounds in funding to manufacture a 42 light bulb that lets you have a disco in your kitchen, The Telegraph reported.

The LIFX light bulb will give users the power to quickly dim the lights for a romantic evening in or switch on the disco strobe for an impromptu rave. At 42 each with a lifespan of 25 years, the bulbs cost a staggering amount compared to normal energy-saving fluorescent bulbs, which can be picked up for as little as 2 and typically last for 10 years.
The project has, however, seen an astonishing level of support since it launched. Billed by company founder Phil Bosua as the worlds smartest light bulb, the bulb will screw into normal light fittings and function like a normal light bulb if you lose your phone. Traditional bulbs also use heaps of power and those energy efficient fluoro bulbs have that cold white light that we all hate, Basua said.

Being Aware of your Thoughts is Energy Alignment

We are the Creator of our story and the energy that flows within us is the magnet to attract our outer experience which matches the frequency or vibrational feeling attached to the thought. It doesn't matter if the thought is conscious or unconscious. It's all those unconscious, limiting beliefs that are holding us back from creating our life on Purpose and with Purpose. If you think life is a struggle, it will be a struggle. If you think you are tired, you will be tired. If you think you are happy, you will see things appear that make you happy. Our thoughts are like a big magnet - what we think is magnetized or attracted to us.

Blue Brain Technology

“Blue Brain” – The name of the world’s first virtual brain. That means a machine that can function as human brain. Today scientists are in research to create an artificial brain that can think, response, take decision, and keep anything in memory. The main aim is to upload human brain into machine. So that man can think, take decision without any effort. After the death of the body, the virtual brain will act as the man. So, even after the death of a person we will not loose the knowledge, intelligence, personalities, feelings and memories of that man that can be used for the development of the human society. IBM is now in research to create a virtual brain. It is called “Blue Brain “. If possible, this would be the first virtual brain of the world. With in 30 years, we will be able to scan ourselves into the computers.

We can say Virtual brain is an artificial brain, which does not actually the natural brain, but can act as the brain. It is possible by using a super computer, with a huge amount of storage capacity, processing power and an interface between the human brain and this artificial one .Through this interface the data stored in the natural brain can be up loaded into the computer .So the brain and the knowledge, intelligence of anyone can be kept and used for ever, even after the death of the person.
Today we are developed because of our intelligence. Intelligence is the inborn quality that can not be created. Some people have this quality, so that they can think up to such an extent where other can not reach. Human society is always need of such intelligence and such an intelligent brain to have with. But the intelligence is lost along with the body after the death. The virtual brain is a solution to it. The brain and intelligence will alive even after the death.

Safeguard your liver get vaccinated

Healthy, hygienic habit and vaccination can keep you away from Hepatitis A.

Hepatitis A is a liver infection caused by the Hepatitis A virus (HAV).Although not a fatal disease, hepatitis A can lead to physical weakness and severe exhaustion which can take weeks or months to overcome.

Symptoms:
The symptoms of hepatitis A range from mild to high fever, malaise, loss of appetite, diarrhoea, nausea, abdominal discomfort, dark-coloured urine and jaundice a yellowing of the skin and whites of the eyes. These symptoms are known to be more severe in adults than children.
Who is at risk:
Anyone who does not have a prior history of HAV infection or hasn’t been vaccinated against it runs the risk of contracting hepatitis A. Most HAV infections occur during early childhood.
Living amidst poor sanitation where the virus is widespread, injecting drugs, living in a household with an infected person, or being a sexual partner of someone with acute HAV infection and usage of sewage contaminated or inadequately treated water raises risks of getting the disease. It spreads from person to person through faecal-oral transmission and blood-borne transmission.
Treatment and prevention
There is no specific treatment for hepatitis A. Improved sanitation and hepatitis A vaccinations are the most effective ways to prevent this disease.
Adequate supply of safe drinking water and proper disposal of sewage within communities, combined with personal hygiene practices such as regular hand wash reduce the spread of HAV.
Vaccination is a must
As we Indians fall in the category of intermediate risk of HAV infection, also known as intermediate endemicity, where transmission occurs primarily from person to person in the general community, often with periodic outbreaks, hepatitis A can be controlled through vaccination programmes.Two doses of the vaccine, given at an interval of six months, can protect you from the infection for a period of 10 years. The vaccine can be given as part of regular childhood immunisation programmers after the age of one.
The vaccine is a must if you are suffering from a chronic liver disease, are a Haemophylic patient, a medical person working with or treating HAV patients, or are a homosexual male. Anyone above the age of one, who has never been inoculated against the hepatitis A virus, and wants to be safe, should also be vaccinated.

Easy Ways to Healthy Eyes

1. Eat greens. Ingesting lots of leafy green vegetables like spinach, collard greens and kale help avoid macular degeneration.

2. Commitment to doing eye exercises to improve vision, and committing to making the kind of dietary and lifestyle changes that can help you get rid of your glasses, will help you see; and it will assist you in many other areas of life as well.

3. Sunlight is extremely beneficial to the eyes. You receive less than 10% of the energy of the Sun if the rays are coming through a window or the lenses of your glasses, so go outside without glasses (especially without sunglasses) for at least 15 minutes a day. It's good for you!

4. Eat apricots and blueberries. Blueberries are associated with reduction of eye fatigue and apricots are rich in beta carotene and lycopene, both of which promote good vision.

 

5. Get plenty of Omega 3 fish oil. It helps clear eyesight and eye health. (Heart-healthy diets in general tend to be good for the eyes as well, since blood circulation is so important to eye health).

6. Pamper your eyes. Try placing two slices of soothing cucumber over closed eyes for 15 minutes. It cools and refreshes the eyes.

7. Drink tea. It’s thought that drinking tea might help to deter cataracts.

8. Incorporate the following three things into your life daily and make them a subconscious habit by doing them consciously until they stick in your brain: Blinking every 2-4 seconds, breathing from your stomach (see how shallow your breathing becomes when working on a computer. Eyes require a great deal of oxygen to function properly), and shifting your eyes from point to point rather than trying to see an entire object all at once.

9. Drink more pure, flat, filtered water and increase the amount of high quality oils you eat and you'll not just improve your vision, but also your overall health.

10. Give them a break. If you work at a computer, remember the 20/20/20 rule. Take a break every 20 minutes. For 20 seconds, look at something 20 feet away or farther. This allows your eyes to refocus and relax and prevents the blurry vision that can occur by staring at a computer screen for too long.

11. It's not so much about exercising your eyes daily as it is relearning the old habit of proper vision. Did you need exercises to see properly when you originally had perfect sight? No, you just looked at the world in a different way than you do now. The correct way to view the world is by performing the three habits mentioned in the article: Blinking, Breathing, and Shifting.

Be Aware of Google Doodle

The Google Doodle is those cool logos you see on the Google search page. These logos are often animated and interactive. The logos often coincide with major holidays or world events. Originally designed by Googlers the general public can now submit designs for the Google Doodle.

The first Google Doodle was made in 1998 by Sergey Brin and Lary Page for the "Burning Man Festival." They wanted to alert Google users of their absence in the event of a server crash at Google. From that point the Designs were made by designers not employed by Google until 2000. In 2000 an intern at Google was asked by Larry and Sergey to do the Google Doodle. Dennis Hwang was the intern they asked to do the Doodles. He has been doing the Google Doodle ever since with other Googlers.
Google Doodles violate a long accepted tenet of brand management: that a logo must be respected and used correctly and consistently at all times. A constantly changing logo was thought to reduce brand equity. While this may be true of many brands, Google has successfully defied the orthodoxy; the Google logo has constant charming, interactive engagement that gets much press and buzz.
The Google team has created over 1,000 doodles for our homepages around the world. A group of Googlers get together regularly to brainstorm and decide which events will be celebrated with a doodle. The ideas for the doodles come from numerous sources, including Googlers and Google users. The doodle selection process aims to celebrate interesting events and anniversaries that reflect Google's personality and love of innovation. The doodle team is always excited to hear ideas from users - they can email proposals@google.com with ideas for the next Google doodle.
