Further reasurch into the World Wireless System

When many people think Nikola Tesla they think of a geek, a joke, a failure. But I have been doing some reasuch into what he considered one of his greatest ideas I I just had to ask why we are not trying to get this to work.The idea was called the world wireless system. Basically it was a telecomunications system that was able to do radio, but also to broadcast electricity wirelessly.

Now what that means is imagine wifi. Now imagine that instead of giving you access to the internet, this wifi sent electricity that was picked up by a small antenna on your electrical devices or picked up by a larger station that would disperse that energy along the power grid. Now also imagine that the power station is on the other side of the country.

That is tesla's idea was the idea that energy could be sent anywhere without wires. Nowin todays world, this would be a major thing. Imagine electric cars that no longer needed to be charged because they were being powered wirelessly while you drive. Imagine your smart phone never going out or kids toys not needing batterys.

So what I am thinking is that we need this. We need to start fixing it so that this works. Tesla thought he could get it working with tech 100 years old today. Surely with all of the technological advancements we have made in the last 100 years we could prove it possible, maybe even make it work.


  • Feb 12 2014: What would cause wireless energy transmission to be inefficient?
    • Feb 12 2014: The problem is with physics questions, is that you can't properly answer them without starting to resort to mathematics, at which point gazes glaze over and whomever you're answering has pretty much lost interest.

      My advice is to just take it for granted they're less efficient, and keep going from there. Or sign up to some academic courses about materials and electrical engineering--whichever you prefer.
      • Feb 12 2014: taking it for granted goes against science itself, eh? There must be some basic principles or laws of physics and/or costs that explain the inefficiency...without being a physicist it would seem to be a very efficient and ultimately desirable way of getting energy throughout our society...
        Does electricity degrade from friction of air particles or is there a loss of concentration of a signal or some other explanation that begins to explain why it is inefficient
        • Feb 12 2014: Again, without a physics, engineering or mathematical background, explaining is difficult.

          Copper wires allow free flow of electrons through metallic crystalline structures. Once you take all the measurements and do all the calculations, you come up with that its a very efficient way of transporting them. That's not to say its the most efficient method. Silver is a better conductor using the same principle, but is rarer and more expensive. Super conductors are even better, but they need cooling to somewhere on the order of -200 Celsius, which presents all sorts of logistical problems; their method of electron transport is also different, something to do with quantum mechanics beyond my comprehension, if I recall correctly.

          All the wireless methods simply don't preform as well as a solid medium.
          Electric forces in a vacuum grow exponentially weaker with distance, and are further interrupted by most material mediums if you're not in a vacuum; there's an equation that shows it quite nicely. Magnetism is similar in that regard.
          Photons (visible light, radio, x-rays, that sort of thing; only difference is frequency) made from the electrical energy can be used to transport energy well enough, but the act of changing from electric flow to photons and back is quite inefficient in of itself.
          There may be other methods I can't name off the top of my head, but the simple fact they aren't in common use already suggests they aren't practical.

          Its hard enough explaining these things properly with empirical test results and a high degree of mathematics. Without those tools, its something of a lost cause.
          Its sort of like trying to build the fifth floor of a skyscraper before laying the foundations. You can put it up there, but it'll just fall back down.

          I'm not trying to deride your intelligence or anything, honestly. Without an appropriate background, its hard to understand any advanced material in any field.
      • Feb 14 2014: Nadav thanks for the expanded explanation, i appreciate the time and effort. I understand your explanation, it doesnt deride my intelligence, it supplements it.
        From a lay persons perspective it seems the world has gone wireless and most of us appreciate the convenience. Maybe large scale transmission of electricity isnt the in the cards, but maybe small scale is..say a single device within a home that transmits electricity to all of the devices and things we now plug into outlets...maybe this will be an outcome in the near future.. large scale electrical transmission will still be delivered via copper wires and through the existing infrastructure but once it reaches the home or office, it will be fed into a single device that transmits throughout the building or space. I like the idea...
  • Jan 23 2014: Probably not the best of ideas, actually.

    Don't get me wrong, I have a deep appreciation for Nickola Tesla. There's a reason they call him "the man who invented the modern world".
    However, later on in life, plagued by problems of both personal and financial nature, he hatched some pretty hair brained schemes. Some at least were an attempt at publicity, and perhaps further funding, but that doesn't change the fact they don't work--at least not in a practical manner. The earthquake machine, death ray, and some others just don't work as advertized.

    Wireless power transmission (whether through the air or ground) is quite inefficient compared to more conventional methods like copper wires.
    People occasionally use it for their phone as of late, mostly because they don't require much power, so not much is wasted in absolute terms. Powering anything more substantial though, like say, industry or a city's worth of laundry machines and air conditioners, the loss incurred would be unacceptable both financially and ecologically.

    Jan 23 2014: The great misunderstanding of the Tesla tower is that it 'creates' free energy. It does not. It's a wireless way to transmit energy once it's been generated by another source, but it does not itself create the energy.
