Energy is life and it’s precious. Most of the energy is derived from non-renewable sources of energy like coal and petroleum products. Now to some extent Natural gas also. Most of us are aware that these sources are depleting day by day. Very high usage of energy for a good life style have lead to this situation. I have been writing about this in between my posts so that at least one will try to save energy.
To keep up with demand and supply curve , now the energy is collected from sun via solar cells. These solar cells are there for quiet a long time. Due to high cost in manufacturing and then as a product very few were buying these. Most of the times they are used by laboratories or by the peoples who can afford those. But the new breakthroughs will change the current situation and may increase the penetration of solar cells.
The first breakthrough is by a Canadian base company who is successful in creating a solar cell which will reduce the cost by 25%. It will also increase the efficiency of solar cells up to 19%. Currently the efficiency of solar cells is about 15%. The new Generation II technology will also speed up the manufacturing process reducing the production costs by 25%. The current Generation I cells have an efficiency of 14.7%.
Another breakthrough is by an Australian PhD student who is successful in creating solar cell out of everyday used items such as inkjet printers, nail polish and pizza ovens. He calls this technology as iJET which is really helpful to developing countries. This technology uses the current low-cost inkjet printing process to create the cell. The beauty of the iJet is that it can be made at room temperature and without high-tech environments or components.
I will surely buy solar cells if their cost reduces to an extent where I can afford them. This energy is renewable and comes free. There will be also less or no hard to our environment.
Am I mobile addict? You may be thinking of this question as this is second post in technology which falls in mobile technology. Not really. But these small pieces of plastic or fiber or whichever material they are made up of make our life a lot easy. We have to keep up with them. So this is another post. Last week I received an e-mail regarding this phone. And I was really surprised with the concept. It is just mind blowing.
So far you have a certain shape of mobile set in your mind. Mobile phone means it will have a screen and on backside a cover with battery to change. There will be buttons from 0-9 and some extra. Some mobile may have music related buttons. A port to connect to PC or laptop and a charger. Isn’t it? Now change your mind. Here comes a phone which will shatter the traditional image of mobile phones. Here is Nokia 888.

Everybody is talking about iPhone. What’s so special about this gadget? What is making this different from others? I am not suppose to be reviewing this gadget. And I will not and cannot do that as I can’t afford this phone. Maybe some guy will allow me to use this phone and then i can review. But till then let’s get some cool features and technology behind this phone. Also the reason for this post is due to it’s launch in India. It is now provided by Airtel and Vodafone at a price which will make a deep hole in your pockets.
Apple is a brand known for user interface and user friendliness. After watching many videos and reviews I think it’s true. The first thing in features is the memory. This phone has inbuilt flash memory, It comes in two variants 8GB and 16GB. This is one of the greatest achievement in phone arena. Till date phones were running on memory based on cards which is slow. Flash memory is inbuilt and is much faster than memory card. That will improve performance but if you loose phone it’ll be difficult to recover data unlike cards which can be removed and can be read in card reader. Continue reading →
This is a fantasy. We have been watching many films and read stories about people who have the power of being invisible. Sometime back I saw films like “Hollow man” and “Mr. India“. That sometime was a long ago you can say. I always wished to have that power and use it against the evil. The first film here though frames the dark side of being invisible. I think everyone will love to be invisible.
Scientists are a step closer to being invisible. This will not only make humans invisible but any object. Scientists have engineered a new material which can control the direction of visible light. The logic is simple. Just bend the visible light away from the object and it becomes invisible. There is no injection or any kind of drug required. This can also hide large objects like ships and plane. Continue reading →
Human eye is one of the best creations and it’s one of the best part of our body. The best part varies from person to person. The news is about an eye shaped camera which resembles human eye. It was successfully designed by the US scientists using standard sensor materials. Looking at the picture it looks to be an ideal solution for bionic eye.
This is a great boon to those who are blind. This breakthrough should help them to see this beautiful world again. The scientists have said that this could be well used for an artificial retina. I don’t have to tell you how important is this retina for our eyes. It is first time that the camera is demonstrated on curved surface to make it look like human eye. Picture tells us how successful the attempt is.
The surface may well look curved but is made up of very small squares. These tiny squares hold the photo detectors and electronic components. The squares are connected to each other with tiny wires which help the squares to mould into curve surface. It is difficult task to mount the circuit boards on curved surface as they come only in flat shape. The above solution helped to mount the components without breaking them.
Another good use of it may be in the robots. Current generation robots could be improved to a great extent with the use of this eye shaped camera. They will also resemble human beings more precisely. Only time will tell us where this ground breaking invention will lead us. Till that time comes you can keep reading my blog and..
