Power from Sun – Solar Cells
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.
A step closer to invisibility
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 →
Jetpack – Flying Dream
Amazing!!! Isn’t it?? This is an important news for me. I have always dreamed of flying. I’ll someday achieve this dream. But it’ll take a long time. So till then my dreams are my companion and my inspiration. Let’s not talk about dreams. I’ll write in detail about that. The Jetpack you see is invented by a New Zealand inventor Glenn Martin.
The inventor worked very hard and spent many years on that machine. There are many advantages and disadvantages of this Jetpack. I’ll mention them further. It looks a lot different from what it is. The usage of this jetpack are endless. It surely provide good attention on safety. This product is still not final and is still in beta stages. Continue reading →
Nonsense Revamped
After a lot of thinking (???) I made a list of changes for my blog. These changes are due to very less time I am getting online. I need some sleep. Currently I sleep around 1-1:30 am. I hardly get six hours of sleep which is necessary for anyone. In order to make my life easy and continue blogging journey I decided these changes. This is to achieve 30 readable posts per month. So here are the changes.
1) Sunday Review: I read a lot of blogs. Some are good, some are bad and some are ugly. I want to review them. Bad and ugly blogs need to be improved or else find a place in bin. I don’t expect backlinks or blogroll links or any mention for this. If they feel it’s necessary then I’ll be happy. I expect all my criticism if any to be taken in positive manner. I want blogs to improve including my blog. If you don’t take it positive then you know what happens when positive meets negative. A short circuit.
2) Tuesday Readings: These are the posts I liked. It is not necessary that all blogs have all good posts. But I feel every blog contains at least one good post. And I’ll just try to pick that out. Don’t ever check the date and time of the post. The post may be a day old or a week or a year. Maybe more than that. I’ll post what I liked and read in past week or so. Continue reading →
