FloDesign high efficiency Wind Turbine

Alternative sources of energy is one of the hottest topic theses days. Wind energy is not being utilized to its full potential due to the lack of technology available in the field. The design of the wind turbine has been almost the same since historic times.

But a company by the name FloDesign based in Wilbraham, MA, USA. has come with a highly efficient wind turbine design. Traditional wind turbines are huge and require a lot of space and infrastructure for installation and transport. They have to be installed in remote areas away from people cause of safety concerns. They require huge and heavy gearboxes which require maintenance, Plus they are fragile and cannot bare high speed winds.They can only extract 50% of winds potential energy.

How to save videos from Video Streaming websites without any software

Video streaming websites are increasing getting popular these days but the problem is sometimes you need to download video on your hard drive, may be for some project or just to watch it offline. Well there are a lot of free video downloader’s you can use. But I have found a trick which will help you save any video from any video streaming site without the hassle of installing a software plugin or other stuff.
Many people have slow internet connection or limited data plans this trick will help you save a lot of bandwidth too. All you have to do is just watch the video normally and minimize your firefox browser and follow the instructions. It’s simple.

Prerequisites:
Before you read further, you need some stuff to be checked and done.

1)      You need Mozilla  Firefox Browser (latest version will be best)

2)     I have tried it on Windows XP and Windows 7 so you should have either of the two or                        Win.Vista will do.

3)      You need to change a small setting i.e. Your Hidden files and folders should be visible.

Witricity : Wireless electricity

Wires have been used to transport electricity from a long time but, they are messy they get entangled where you don't want them to and come in your way and may even give you an electric shock in some cases. In a sense they are good to transport electricity over long distances but cause a problem when they are used over short distances, in homes and offices.The solution is here "Witricity"

What is Witricity Technology??

If you are thinking its done with electromagnetic radiation then you are wrong. Instead it uses magnetic radiation which makes it safe with no bad effects on the human body. We are surrounded by earths magnetic radiation.Witricity uses the same concept used in a regular transformer,i.e. magnetic induction. The only difference is these guys have done it over a considerable long distance with the help of something called  resonant magnetic couple. Resonant magnetic couple is like transferring energy in the form of waves, the energy is transferred as magnetic energy and converted into electrical energy where it is used in devices. It can pass through any kind of obstructions.

Atlas Copco offers a green compressor technology

With global warming on the rise its really important for industries and companies to stay upto date with the with the latest green technology. Some countries have stringent carbon emission rules to curb carbon emission and also levy heavy tax duties. So Energy saving is very important. 

Atlas Copco is a Swedish Company recognized world wide for its quality industrial products and solutions since 1873. Atlas Copco has come up with a with a great and ingenious compressor technology called the "Net zero energy consumption compressor". By the name it sounds like, Is it a perpetual motion machine?? 
No it isn't! 

The concept behind this technology is heat energy recovery.Compression of air at high pressures produces a large amount of heat which is lost in the atmosphere and the precious energy in the form of heat is lost.

Lotus Omnivore Engine: 10% better fuel efficiency

Internal Combustion engines have been driving the world around for the last 100+ years. They are widely used because of their of their rugged construction and reliability to work in any condition, they still rule the world but, they are polluting and hence don’t seem to have a great future cause of the threat of global warming facing our planet. As a result a lot of companies are trying to refine the engine and develop new technologies.   Lotus Engineering has come up with a type of engine called the “Omnivore engine”. Lotus reviled the engine concept at the Geneva Motor show earlier this year. Now they seem to be running test trials and test show that the Engine achieves 10% better fuel economy compared to direct injection engines, with ultra low emissions. The engine takes advantage of electronic engine management technology; it can run on any liquid fuel hence the name Omnivore. 

The most interesting thing about this engine is that it has variable compression ratio(10:1to 40:1), it is achieved by a puck at the top of the cylinder which moves up and down thus affecting the volume/compression ratio of the engine. The Engine operates on a two stroke cycle and has homogeneous charge compression ignition (HCCI), As a result the engine does not require a spark plug just like a Diesel engine. Unlike 4 stroke where downsizing the engine increases its fuel efficiency here up sizing the engine improves fuel efficiency i.e. bigger the engine the better efficiency it has.
The prototype engine is a 500cc single cylinder mono-block engine. For practical application Lotus plans on developing a multi cylinder engines and is in talks with other companies. It is quite promising and as a result of it simple construction it will be cheaper to manufacture and thus we’ll have cheaper and more efficient greener cars in the future.
