Typing “Tesla Coil” in Google, yields more than 563,000 results, many describing the Tesla Coil as the premiere wireless energy transfer technology of the 20th Century that never quite became commercialized. Why is this technology still so compelling to energy enthusiasts and conspiracy theorists alike more than 100 years after its invention?
The docent who demoed the unit confirmed that transmission of electricity through the air was the original aim of this technology. My blog has recently covered WiTricity, a modern wireless electricity transmission approach (see “Although Revolutionary, WiTricity is a Technology We Cannot Adopt” and “MIT Team Invents ‘WiTricity’ Wireless Energy Transfer”). So, I asked the docent why Tesla Coils had never been commercialized. His explanation was that air-imposed electrical resistance is so great that Tesla Coils cannot compete with wired networks for transmission over long distances. I suspect this answer is only part of the reason since electromagnetic fields do permeate air (even vacuum). The visible spark (as in the above picture) occurs only when air’s break-down voltage is exceeded.
Nonetheless, some believe that Tesla Coils represent a 100-year-old viable energy transmission and generation technology that has been suppressed through the so-called Tesla conspiracy. The alleged story is that the government invaded Telsa’s residence shortly after his death and confiscated all his manuscripts pertaining to alternative energy. A huge on-going effort has been invested in pursuing the Tesla conspiracy, as evidenced by a series of Coast to Coast radio programs posted on You Tube starting with “The Tesla Conspiracy: Mark DeMucha Pt.1”.
Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
