세상을 바꾼 니콜라 테슬라의 발명 10가지


1. Alternating Current – This is where it all began, and what ultimately caused such a stir at the 1893 World’s Expo in Chicago. A war was leveled ever-after between the vision of Edison and the vision of Tesla for how electricity would be produced and distributed. The division can be summarized as one of cost and safety: The DC current that Edison (backed by General Electric) had been working on was costly over long distances, and produced dangerous sparking from the required converter (called a commutator). Regardless, Edison and his backers utilized the general “dangers” of electric current to instill fear in Tesla’s alternative: Alternating Current. As proof, Edison sometimes electrocuted animals at demonstrations. Consequently, Edison gave the world the electric chair, while simultaneously maligning Tesla’s attempt to offer safety at a lower cost. Tesla responded by demonstrating that AC was perfectly safe by famously shooting current through his own body to produce light. This Edison-Tesla (GE-Westinghouse) feud in 1893 was the culmination of over a decade of shady business deals, stolen ideas, and patent suppression that Edison and his moneyed interests wielded over Tesla’s inventions. Yet, despite it all, it is Tesla’s system that provides power generation and distribution to North America in our modern era.


2. Light – Of course he didn’t invent light itself, but he did invent how light can be harnessed and distributed. Tesla developed and used florescent bulbs in his lab some 40 years before industry “invented” them. At the World’s Fair, Tesla took glass tubes and bent them into famous scientists’ names, in effect creating the first neon signs. However, it is his Tesla Coil that might be the most impressive, and controversial. The Tesla Coil is certainly something that big industry would have liked to suppress: the concept that the Earth itself is a magnet that can generate electricity (electromagnetism) utilizing frequencies as a transmitter. All that is needed on the other end is the receiver — much like a radio.


3. X-rays – Electromagnetic and ionizing radiation was heavily researched in the late 1800s, but Tesla researched the entire gamut. Everything from a precursor to Kirlian photography, which has the ability to document life force, to what we now use in medical diagnostics, this was a transformative invention of which Tesla played a central role. X-rays, like so many of Tesla’s contributions, stemmed from his belief that everything we need to understand the universe is virtually around us at all times, but we need to use our minds to develop real-world devices to augment our innate perception of existence.


4. Radio – Guglielmo Marconi was initially credited, and most believe him to be the inventor of radio to this day. However, the Supreme Court overturned Marconi’s patent in 1943, when it was proven that Tesla invented the radio years previous to Marconi. Radio signals are just another frequency that needs a transmitter and receiver, which Tesla also demonstrated in 1893 during a presentation before The National Electric Light Association. In 1897 Tesla applied for two patents US 645576, and US 649621. In 1904, however, The U.S. Patent Office reversed its decision, awarding Marconi a patent for the invention of radio, possibly influenced by Marconi’s financial backers in the States, who included Thomas Edison and Andrew Carnegie. This also allowed the U.S. government (among others) to avoid having to pay the royalties that were being claimed by Tesla.


5. Remote Control – This invention was a natural outcropping of radio. Patent No.613809 was the first remote controlled model boat, demonstrated in 1898. Utilizing several large batteries; radio signals controlled switches, which then energized the boat’s propeller, rudder, and scaled-down running lights. While this exact technology was not widely used for some time, we now can see the power that was appropriated by the military in its pursuit of remote controlled war. Radio controlled tanks were introduced by the Germans in WWII, and developments in this realm have since slid quickly away from the direction of human freedom.


6. Electric Motor – Tesla’s invention of the electric motor has finally been popularized by a car brandishing his name. While the technical specifications are beyond the scope of this summary, suffice to say that Tesla’s invention of a motor with rotating magnetic fields could have freed mankind much sooner from the stranglehold of Big Oil. However, his invention in 1930 succumbed to the economic crisis and the world war that followed. Nevertheless, this invention has fundamentally changed the landscape of what we now take for granted: industrial fans, household applicances, water pumps, machine tools, power tools, disk drives, electric wristwatches and compressors.


7. Robotics – Tesla’s overly enhanced scientific mind led him to the idea that all living beings are merely driven by external impulses. He stated: “I have by every thought and act of mine, demonstrated, and does so daily, to my absolute satisfaction that I am an automaton endowed with power of movement, which merely responds to external stimuli.” Thus, the concept of the robot was born. However, an element of the human remained present, as Tesla asserted that these human replicas should have limitations — namely growth and propagation. Nevertheless, Tesla unabashedly embraced all of what intelligence could produce. His visions for a future filled with intelligent cars, robotic human companions, and the use of sensors, and autonomous systems are detailed in a must-read entry in the Serbian Journal of Electrical Engineering, 2006 (PDF).


8. Laser – Tesla’s invention of the laser may be one of the best examples of the good and evil bound up together within the mind of man. Lasers have transformed surgical applications in an undeniably beneficial way, and they have given rise to much of our current digital media. However, with this leap in innovation we have also crossed into the land of science fiction. From Reagan’s “Star Wars” laser defense system to today’s Orwellian “non-lethal” weapons’ arsenal, which includes laser rifles and directed energy “death rays,” there is great potential for development in both directions.


9 and 10. Wireless Communications and Limitless Free Energy – These two are inextricably linked, as they were the last straw for the power elite — what good is energy if it can’t be metered and controlled? Free? Never. J.P. Morgan backed Tesla with $150,000 to build a tower that would use the natural frequencies of our universe to transmit data, including a wide range of information communicated through images, voice messages, and text. This represented the world’s first wireless communications, but it also meant that aside from the cost of the tower itself, the universe was filled with free energy that could be utilized to form a world wide web connecting all people in all places, as well as allow people to harness the free energy around them. Essentially, the 0′s and 1′s of the universe are embedded in the fabric of existence for each of us to access as needed. Nikola Tesla was dedicated to empowering the individual to receive and transmit this data virtually free of charge. But we know the ending to that story . . . until now?

모든 물건에 인터넷이 연결되는 세상이 온다.

인터넷 유비쿼터스 시대는 이미 도달하였습니다.

모든 사람과 사물이 인터넷을 통해 웹에 연결되어 있는 그런 시대이지요.

BUSINESS INSIDER가 이 인터넷 유비쿼터스시대의 미래를 슬라이드로 만들었네요.

특히 사물인터넷의 경우, 지금까지는 인터넷이 PC, 태블릿, 모바일이 주로 점유하고 있지만, 3년 후 쯤이면 사물 인터넷이 이들을 모두를 합한 것을 초월할 것으로 보고 있습니다.

여부 분야에서의 현황과 우리에게 닥칠 변화, 그리고 각 분야에서 어떤 이점과 문제가 있을지를 잘 짚어주고 있습니다.

정말 좋은 정보입니다.

모든 곳에 인터넷이 연결되는 시대! 우린 무엇을 준비해야 할까요?

아마존, 주문한 물품을 30분 이내에 배송한다.


피자 배달이 아닙니다.
아마존의 CEO 제프 베조스가 어제 선데이나잇의 60분 인터뷰에서 발표한 말입니다.
어떻게 그렇게 할 수 있냐고요?
우리나라 처럼 오토바이 택배를 이용한 것은 아닙니다.
바로 하늘을 나는 드론을 이용하는 것이지요.
베조스는 현재 다양한 테스트를 시행 중에 있고, 적어도 5년 내에는 현실화시킬 수 있다고 장담합니다.

하늘을 나는 드론은 완전히 자율적으로 동작한다고 합니다.

꿈과 같은 이야기지요?

머잖아 택배 드론이 우리 하늘을 윙윙 날아다니는 모습을 보게 될까요?

동영상을 참조하십시오.
세상 참 겁나게 변하고 있습니다.

유저 10억명의 플랫폼!

어떤 플랫폼들이 이 꿈과 같은 경지에 올랐을까요?

최초는 윈도우, 

그 다음이 페이스북, 

가장 최근에는 안드로이드입니다.

iOS는 현재 6억명 정도. 잘하면 내년 쯤 1B 그룹에 들어갈 수 있을 것으로 예측.

안드로이드는 출현하니 불과 5년만에 1B의 유저를 확보했습니다.

가상 배구 경기를 촉감으로 느낄 수 있을까?

나비가 손등에 앉았다 날아가거나, 갈매기가 머리 주위를 나는 느낌을 느낄 수 있다면?

전쟁 게임이나 스포츠 게임 등에서 가장 아쉬운 것은 촉감이다.
타격, 격파, 접촉 등과 같은 촉감을 느낄 수 없다는 것이 무엇보다 허전한 일이다.

이 아쉬움을 달래주기 위해, 팬실배니아 피츠버그에 소재한 디즈니 연구소가 Aireal이라 불리는 촉감 기술을 개발했다.
이 기술의 요지는 프로그램 상에서 가상의 물체가 이동하는 것과 동기하여 에어건이 도너츠 형태의 소용돌이 공기를 발사한다. 사용자는 이 공기를 통해 가상 물체를 피부로 느끼게 된다. 동시에 시스템은 사용자의 제스처를 피드백 받아 인지한다.

이 시스템을 통해, 동영상에서 볼 수 있는 바와 같이, 가상의 배구게임을 즐길 수 있고, 손등에 나비가 앉는 느낌을 느낄 수도 있다. 
그리고 갈매기가 머리 주위에서 날개짓을 하는 것도 사실감있게 느낄 수 있다.

이 기술이 상용화된 환경을 상상해본다.
우리에게 어떤 기막힌 경험을 제공할까?
