wireless electricity - the future is now
Following up on the hard work and passion of the late Michael Faraday and Nikola Tesla, electromagnetic induction has come back to the forward area of electrical science and is soon to be within commercial and consumer markets in the very near future (in some cases it has already arrived). Several firms have developed new products that can effectively pass electricity through open space. This breakthrough could foretell some very unique changes to the way in which we use electronic devices. When you think of it, how mobile is your telephone if it cannot go but for a few hours without a charge? Or how portable is that laptop computer of yours if it must be fed every so often from an outlet? These issues are on the verge of being solved. Assuredly some prominent stakeholders are concerned, while others are adopting and make inroads in this exciting technology.
The first of these breakthrough product categories to make it to market is one that involves inductive coupling. Tesla must be smiling in his grave as his theory has come to fruition. This scalable version is much smaller version than the original design. It is shaped like a mouse pad and emits power through the air to a given electronic device. The point of origin is a powered coil inside the pad which generates a magnetic field. This propels the current towards the electronic device and then into a secondary coil which then charges the apparatuses’ internal rechargeable battery. Imagine not having to deal with the hassle of cords being tangled and the related frustration. Also the pads are ‘smart’, paying notice to whether authorized devices are being used and of the specificity of products. As you can see the practicality of this is massive to both the commercial and consumer marketplaces.
Radio frequency harvesting represents the next wave of wireless electricity mastery. This style of system is very unique in that it morphs the electricity into a radio wave format and then propels it across an area to the receiving hub. Upon reception by the ‘power hub’ they are converted into low power direct current which is then available for usage. Applications that this will be seen in first include small appliances and wireless sensors. Ultimately, the user will be able to simply drop the electronic good within a charging box and then pick it up after a charging session fully replenished. This product will be available later this year. This product would be a fantastic addition to modern classrooms of today with all of the gadgets that are employed within them for instruction.
Perhaps the brightest star in the room is what is known as magnetic coupled resonance. This technique allows an entire room to be powered by a single system (provided that the room is fitted with enabled devices). Magnetic coupled resonance changes the game in that the coils do not have to be close to each other in order to function as in previous wireless electric technology. For this to work seamlessly, it is required that the timing/tuning of the power coil and the receiving coil match. This is similar to when a piano is tuned. What can be said with certainty is that wireless electricity is here to stay, keep your eyes open as it is coming to a consumer market near you.
