Well nowadays this information spreading everywhere all over internet (blogs, Facebook, YouTube, etc.) that you can charge your mobile phone battery with Sacred Fig Leaves. Some says its true and some says its hoax. They say following guidelines to charge your mobile battery:

This conceptual vehicle offers one different point of view over the pollution problems in the big cities. It was designed by Gunwoong Kim and Suji Kim and is equipped with an air filter under the passenger capsule. So here is what we have: fully electric vehicle that ingests dusty and dirty air purifies it and releases clean and breathable air. Sounds good, right? Well, a single car would probably clean small and maybe insignificant amount of air, but imagine thousands of vehicles purifying what you breathe every day?

On May 16-th, 2010, Israel consortium unveiled officially the biggest of its kind desalination station in the world. It works using the principle of reverse osmosis and is placed near the coastal city of Hadera. The Israel Company H2ID, jointly owned by IDE Technologies and Shikun & Binui, developed the project. The station delivers 127mln cubic meters desalinated water, or nearly 20% of the annual consumption of households in Israel.

(Reuters) - An Israeli consortium unveiled the world's largest reverse osmosis desalination plant on Sunday in the coastal city of Hadera, hoping to help alleviate the arid country's water shortage. Israel's H2ID, which is jointly owned by IDE Technologies and Shikun & Binue, said its plant will supply 127 million cubic meters of desalinated water a year, or about 20 percent of the yearly household consumption in Israel.

Ductility and malleability are properties of metals that show specific characteristics. It is the ductility and malleability property that helps the metals to deform. Ductility is said to be the property of a material to stretch without getting damaged. Metals having ductile property can be stretched into wires. An example is copper wire. Malleability is said to be the property of a material to deform under compression. The metals having malleable property can be rolled or beaten into sheets. An example is aluminum foil. In more simple words, ductility means stretching to wires and malleability means beating to sheets, Ductility means that a metal can be changed to another form by pulling, compression or twisting. On the other hand, Malleability means that a metal can be changed into another form by beating or hitting it hard.

Engine The word “engine” comes from the Latin word “ingenue.” An engine is a device or system (electrical, mechanical, chemical, or even social, human, or political) which affects a result. For instance, a bomb is an engine, a crane is an engine, a water-powered mill is an engine, a political party is also an engine, and even a criminal gang is an engine. Gradually through the decades, “engine” became associated especially with boilers, fire, furnaces, and bombs. In short, any device which tended to get hot and explode. However, the system was still considered to be an “engine” and not just the prime mover. In the 20th century, a motor prime mover was called “the engine.” James Watt put the name “steam” in front of the engine to distinguish it from other engines of that time. Engines are basically the devices which convert any form of energy to bring about mechanical effects. These are made up of pistons and cylinders. These may be categorized into various groups according to

Dubai is the place to go if you want to build outrageous or crazy architecture, like buildings as tall as mountains, manmade islands in the shape of the world or, if neither of those is wacky enough for you, then how about an ocean hotel that’s partly submerged in water? That’s the idea for the Water Discus Underwater Hotel from Deep Ocean Technology which is to be built in Dubai and is comprised of futuristic discs which make it look a bit like the Starship Enterprise .

Despite the name, we are not talking about the Jewish legend of David and Goliath . The subject of this article is the largest cannon ever built, unknown why called by its creators “Little David”. His goal was to destroy Japanese bunkers during the invasion of the Japanese main island planned by US Army in 1944 . And, the other reason Little David was built is because of the ineffectiveness of 16-inch (410mm) battleship cannons against the Japanese bunkers. David’s diameter is more than twice bigger – 32 inches (914mm), thus exceeding the calibers of German grand cannons “Karl” , “Dora” and the “Fat Bertha ” (Bertha was the name of the builder’s daughter, she has been really nice and far from fat girl). The biggest siege mortar in the world was, in fact, never used in combat because Japan capitulated and therefore the ground offensive became needless

  People are crazy about ipod, so this iRing concept I believe could be seen in the future. Using this ring, iPod fans can take control of their music player easier, not just for iPod btw, this ring is mend to control all Apple’s Product. Take a look at its stylish design and wireless Bluetooth connectivity with your iPod and iPhone, the iRing allows you to control playback and volume on any of your Apple media devices. iRing features a bright OLED status display with a touch-sensitive function strip, and a rechargeable battery life of up to 2 days.    

Chiba, Japan—Nissan is working toward robot cars one step at a time. Rich DeMuro of KTLA-TV in Nissan's Robotic NSC-2015 Car The auto manufacturer this week at Japan’s CEATEC showed off the NSC-2015, a prototype electric car that can park it self, come when you call it and warn you about burglars. As I sat in the passenger seat, the NSC 2015—a highly modified version of the all-electric Leaf connected to cloud computing services—managed to go forward, slip into reverse, execute a 90 degree turn and back in all on its own.
