What is Wireless Power?

Anyone who attends a class or meeting where most of the participants have laptop computers is well aware that there are never enough power outlets—and when they are available, they are invariably located in inconvenient places. Wireless power, already being prototyped by several companies, promises to alleviate the problem by making power for charging batteries in devices readily available. Using near-field inductive coupling, power can be transmitted through special surfaces or even through open space to charge devices within a home, office, school, or other setting. Consumer products are already entering the market; the Powermat, for instance, charges up to three devices placed onto its surface (each device must first be slipped into a compatible sleeve). Fulton Innovation's eCoupled technology is designed to be built into desk- and countertops, enabling not only power transfer but other wireless communications between devices placed on the surfaces. Witricity is developing transmitters that would be embedded in walls or other furniture, transferring power via inductive coupling to receivers attached to devices anywhere within the home or classroom. The impact of wireless power for education will primarily be felt in learning spaces; the devices we carry will become more useful and easier to maintain, with increased opportunity for longer use in a variety of settings.

(1) How might this technology be relevant to the educational sector you know best?

  • - lisagustinelli lisagustinelli Mar 30, 2016As Director of Technology at a large high school I see first-hand the difficulty a teacher has when a student fails to bring a charger to class and cannot use their Chromebook. The student is forced to sit out the lesson and this is the equivalent to a student coming to class unprepared. - davidwdeeds davidwdeeds Apr 25, 2016

  • - RollandK RollandK Apr 9, 2016 Charging student devices without the trip hazard or danger is huge and very convenient. Lack of sufficient power or charge is the largest concern of mobile users.
  • This would be huge for schools. - spaul6414 spaul6414 Apr 30, 2016Sandra Paul

(2) What themes are missing from the above description that you think are important?

  • - RollandK RollandK Apr 9, 2016 ROI ( Return of investment ) and/or benefits of fully charged devices in the classroom.
  • Ubiquitous access to wifi
    Google's Project Loon balloons travel approximately 20 km above the Earth’s surface in the stratosphere. Winds in the stratosphere are stratified, and each layer of wind varies in speed and direction. Project Loon uses software algorithms to determine where its balloons need to go, then moves each one into a layer of wind blowing in the right direction. By moving with the wind, the balloons can be arranged to form one large communications network. https://www.google.com/loon. Much of the world still is still not connected. Giving people in developing nations the opportunity to join in on our Global discussions and innovations will change how things are done in the world today.- lisagustinelli lisagustinelli Apr 26, 2016 Agree - deirdre.butler deirdre.butler May 1, 2016- davidwdeeds davidwdeeds Apr 26, 2016 - arjana.blazic arjana.blazic May 1, 2016. - shafika.isaacs shafika.isaacs May 1, 2016I agree with Arjana. Microsoft's experiment with TV White Spaces are also worth exploring. https://africa.tvconnectevent.com/tv-white-spaces-broadband-connectivity-beyond-a-basic-human-right/ (Editor's Note: Added here from RQ2.)
