GEN H-4 – World Smallest Helicopter Turned da Vinci Inspiration Become Reality

Did you know that Leonardo da Vinci, the Renaissance age symbolize idol is the first person that draw and sketch out vertical flight machine dated in 1493? Thanks to the drawing of da Vinci, a Japanese flying machine developer, Gennai Yanagisawa had invented a 75-kilogram helicopter. “We named this helicopter ‘GEN H-4′, which it’s has a set of two rotors that spinning in opposite direction. The maximum speed for GEN H-4 can reach up to 50 kilometers per hour,” Yanagisawa said. “The invention process for this GEN H-4 is not an easy task, as it was taking us years of research and budget to invent this great product,” its developer said. Yanagisawa want to dedicate this honor to da Vinci, the magnificent and legend of Renaissance age. His said a GEN H-4 Flying demonstration show will be held in the birthplace of da Vinci in the near future. This GEN…

No More Strays Cat Disturbing with The Pet Porte System

Do you know the estimated population of the cat pet in the world? According to the latest pet population survey, there are over 203,750,000 pet cats in top ten countries, where USA top the chart with 76,430,000 and followed by China with 53,100,000. United Kingdom currently standing in the seventh position with over 7,700,000 pet cats! The number of pet cats expected to be grown in an exponential rate throughout the time. The experts also stated that the pet cats market potential would also increase double or triple in the near future as well. Having cats as our pets or companions is a great daily challenge, as we need to observe and communicate with the cats. The cat lovers require gaining some useful knowledge, if they want to rear an intelligence and talented pet cat. As the cat behaviors doesn’t like dogs, they love to go out and wandering around.…

Higher efficiency solar cells with nano-wires

As Oil prices going up and seems this is going to keep that way, more and more attentions is given to alternative energy sources. Probably solar energy is most attractive due to its nature. Don’t go in to discussions about what alternative energy is the best – all of them are good as long as they are effective. Researchers in University of California, San Diego have been working on “hairy” solar cells. They discovered that growing nano-wires on photocells boost solar cell efficiency. Nanowires help to conduct electrons from collections surface to electrode. “If nanowires are going to be used massively in photovoltaic devices, then the growth mechanism of nanowires on arbitrary metallic surfaces is an issue of great importance,” said Paul Yu, a professor at UC San Diego, and a member of the project team which published the nanowire research. “We contributed one approach to growing nanowires directly on…

Spectacular One Man Show of “Rocket Man”

Who is this “Rocket Man” and what kind of ability his has to crown with this name titled? Well, for your information, “Rocket Man” is a 48 years old Swiss homegrown citizen named Yves Rossi. His currently a chef pilot that mostly flies commercial planes for Swiss Airlines Company. Rossi was a former fighter pilot and an extreme sports enthusiast, have been devoted himself in this “Jet-Powered Gliding” sport since five years ago. “After this extraordinary amazing performance in front of the world with over of million of audiences, the hard training, and my many years of dreaming has finally paid off today,” Rossi said. “It’s been an unforgettable moment, when I’m first strapped on a Jet-Powered wing and leaped from the Swiss-built Pilatus Porter aircraft at 7,500 feet. Thanks goodness I did not forgot to unfold the rigid eight-foot wings strapped to my back before I’m jumping,” said Rossi…

Robotic Suit – The Ultimate Outfit for Super-Soldier

Rex Jameson, a 5-foot-11 with 180 pounds software engineer seems just like others “Average Joe”. When he owns his free time, those extreme sports such as bike hiking, swimming, playing tennis and skies will be his favorite time killer events. Do not be fooled by his appearance, as Jameson was one of the honor software engineers, which has a contract with the U.S. Army and currently working on a top-secret project. You must be wondering, what kind is this so said “Top secret project” thing? Well, Jameson is fully responsible to research, create, and produce a “Robotic Suit” that will be widely used by the U.S. Army in the near future. “Everyday, I need to put on this 150 pounds “exoskeleton” that mostly made up of aluminium and electronics, most of the peoples gets bored on the specimen, instead of gets tired like me,” Jameson said. It’s hard to believe…

LED lamps will replace light bulbs in near future

Seems this can be true. Faiz Rahman who is a nano electronics researcher at Glazgow university states that low-energy bright LED light Bulbs are almost here. As matter of fact LEDs are very energy efficient, but fact is that about 70% of electrical energy is converted to light, and only about 20% of it getting out. The rest of light is trapped inside semiconductor due to high refractive index of LED-air surface. But as Faiz says by making LEDs to let more light out their brightness can be compared to ordinary light bulbs. How to make this happen? This can be done by making series of holes on the surface of LED. Rahman has already made several LED prototypes where holes on surface are about 200nm in diameter (400 times narrower than human hair) and 100nm deep. As LED chip is about 0.3×0.3mm there is enough space for hundreds of…
