The perfect application for wireless power transmission!

Am I the only one who recognizes the perfect application for this technology? I'm no genius, but do posses a talent for problem solving! I ask if I'm the only one because even Mr. Giler missed the application I propose! He invisions this technology to be used to charge the batteries of an electric car, I say, emmbed it in the roadways and eliminate the need for batteries! Imagine a vehicle that never needs to be refueled! By removing the batteries you lighten the weight, and thereby increase the efficiency of the vehicle. You also eliminate the main drawback to electric cars, thier range! Some my ask, but how can you make a profit on wireless powered vehicles. The solution is quiet simple. You treat these roads as toll roads, install a GPS tracking system in the vehicles which contacts the toll operator and logs usage milage. You get a monthly bill for power usage based on a record of milage! Sounds good or what?

    Nov 4 2011: ask Nikola Tesla

    Oct 30 2011: So true, Mr. Braam! Maybe someone could tell the "Occupy Wall Street" organization, to adopt a demand for the banishment of lobbyist from our system of government. Return control to the people and remove the corporate stranglehold. If they could add in a little campaign reform, I believe it would go a long ways in enabling the small to stand against the powerful!

    Oct 30 2011: And if I might continue, Matthew, another curious fact about Tesla. As stated in this documentary, Nikola Tesla was not only interested in electricity, but also Harmonics and the natural vibrations of all things! He claimed to have an earthquake machine. A device that could produce a vibration which would harmonicly match the natural vibrations of the Earth and produce an earthquake. While staying at a hotel across the street from a building under construction the ground began to tremble. As the shaking increased, to the point of near collapse of the building, people crashed the door to his room! Inside, it was reported, they saw Nikola Tesla frantically smashing an unknown device! Knowing this, I'm not suprised that the secret to this wireless technology is in the harmonic vibration of two electric coils! One last thing regarding your snide remark about taxes! What I proposed was a business model, by which, a company who supplied a service, power for an EV, would be able to charge for the service! That's not a tax, but free enterprise at its best!

      Oct 31 2011: Earthquake Machine?

      You lost me there, I don't follow the conspiracies about Tesla.

      He deserves better than that....

    Oct 30 2011: Matthew, you seem to have gotten confused! Might I suggest you re-read the comments and watch the Talk which inspired this conversation! It was actually Lee Berger who suggested to put a charging point at red lights and in my response to his comment that I pointed out the flaws in his concept! When you watch the Talk again notice the TV, I'm pretty certain that the TV doesn't have a battery! This technology involves the wireless transfer of power. The power cord of the past is replaced by an output device which is connected to the power grid, and a recieving device, which is connected to the device, or vehicle, needing power! The reciever supplies the power on demand, thus eleminating the need for a battery! Let me say it again, watch the Talk and pay attention to the demonstration of the TV. There is no battery involved. The power required to operate the TV is delivered wirelessly to the reciever on the back of the TV. The reciever supplies the power directly to the TV! What the Talk doesn't discuss in detail are the limitations of this technology, but they were mentioned. The amount of power that can be transfered and the distance over which it can be transfered. What I actually proposed was embedding the output device beneath the roads, where it could easily be hard wired to the grid, and the recieving device would be mounted to the bottom of an EV. With this setup you would minimize the distance over which you would need to transfer power. Wheather or not this technology can transfer enough power to operate an EV, I don't know! This is not my technology, I merely suggested a different application for its use. And as far as Nikola Tesla, I saw the documentary on him. I'm pretty sure he successfully transfered power wirelessly in his lab, it wasn't a dream! Why else would he spend his own money to build the giant Tesla Coil on Long Island, if not for a public demonstration of this technology! It's just sad that the FBI raided his lab and seized his equipment.

    Oct 28 2011: So how does the vehicle hold power if they do not have a battery? If you think you can just power the essentials at every red light you are surely mistaken. The cars would not go very far if you plan on them not having a battery to house the energy. The charging platform would not power the vehicles long enough for them to reach the next one, in fact they wouldn't even start and I will tell you why.

    The technology to transfer wireless power is there, we have it. But it is very new and undeveloped and requires a battery to retain power from the charging platform. The platform cant transfer power unless there is a receiver that can collect and hold it. You can receive power with out the battery but in order for the vehicle to be powered it has to have electricity flowing through it constantly. Exactly like a smart phone needs electricity constantly running through it to operate. Lets say figuratively speaking that this car was actually moving by some miracle. The moment it drove away from the charging platform at the red light, the vehicle would lose all electricity and stop moving because it drove away from its source of electricity. Just like if I cut a power cord to a TV when its on, the TV turns off. Without electricity the TV can't operate. This is why cell phones, tablets and laptops require batteries, because you cannot have electricity flowing through something without the electricity's source connected to it, whether wireless or by physical connection like a Ethernet cable or battery. A source for the electricity must be present at all times for continuous power.

    That is why I say your idea would not work without a battery. I admit it is a clever way to tax people for energy though. It is easy to forget the nature of electricity and it's technicalities. Maybe one day we will see your idea come to fruition to some degree. Until then there is much research needed in the subject of wireless power as originally dreamed by Nikola Tesla. It's a awesome idea!
  • Oct 26 2011: I suggested a similar idea earlier. For me i would also look at it in potable device applications. you realize that the world is so crazy about making tight software/hardware for mobile devices. very interesting apps have been developed for mobile phones and PCs but the major challenge still remains in the battery capacity. in fact, i think the better the phone, the less the battery capability because apps are battery hungry.
    How about wireless charging of phones and portable devices. This can work in such a way that if you are in an area covered by wireless power, you just turn on wireless power on your phone, and your phone starts charging even when on the move. this way, we are able to have people use their mobiles to the fullest without worrying about battery and charging all the time. There are so many other applications of this especially in third world countries where rural electrification is still a big challenge.

    Oct 26 2011: Well thank you Lee, and good luck with your idea. However your concept eliminates two key aspects of mine. The EV (Electric Vehicle) you envision still requires a large and heavy battery pack, thereby eliminating the increased effiency in EV's I mentioned. And secondly, while your idea may work in urban ares, if I leave my home in S.E. Louisianna and travel to my hometown of Houston, I actually don't stop at a light till I'm about 5 miles from my sister's home. There are no stop lights on highways or rural roads so your EV will not have the range of the ones I discussed. Thanks for the feedback though!
  • Oct 26 2011: Your idea has merit.
    My idea is a little easier to implement. How about a simple power grid installed at traffic lights. When a vehicle stops at a trafifc light and sits over the grid the driver presses a button on the dash of the electric car and connects to the power grid. Like an ez pass the driver is automatically charged based on the power consumption each time the car is charged by the grid. First grids would be portable, as popularity increases municipalities would install permanent grids and receive revenue per charge.
