This is a version of my (and Noel’s) Reuters piece on wireless charging, recorded for the BBC World Service.
Without question, in a few years’ time our children will look back at pictures of this era and ask us what those little pieces of string are snaking across our desktops, bedside tables, mantelpieces and car dashboards.
“They’re cables, son. We used them to charge our devices.”
“Charge them with what, Dad? What had they done wrong?”
You get the picture. In the future, and in some lucky places even now, you don’t need to connect your phone, your tablet or even your car to a charger or wall socket because of something magical called wireless charging. Or to give it its technical term, not having to think about how much juice you’ve got left in your device because you can just lay it on the table in Starbucks, or in the car, or on your friend’s sideboard, and let magnetic induction, magnetic resonance, ultrasound, radio frequencies or whatever technology prevails do its work.
And there’s the problem. For while this is pretty much a no-brainer for anyone who hears about it — what’s not to like about wireless charging? – the reality is that only a handful of devices so far have this capability, and the chances are they won’t play nice with other devices or chargers. So, while we have the technology ready, the people who matter aren’t, by a long chalk.
In fact there are three competing alliances, all with their own fancy websites and hundreds, literally, of members signed up, and that’s not including the two or three other technologies that don’t have alliances but claim to have a better idea.
This is not new of course. We’ve been here before. With video tapes, DVDs, and the first phase of the wireless revolution: when we no longer had to fiddle with telephone wires or ethernet cables and could just yell out: Whats the wifi password?
Companies think they have the edge, the better technologies, more patents, or they just can’t bear relinquishing a bit of control for the greater good, and so we all have to wait while they wear each other down or die trying.
Yes, it’s true that wireless charging might seem like a rich world problem. How hard is it, really, to plug a phone into a charger? Well that’s true. And sometimes what is called wireless charging — like the Apple Watch, where you don’t actually plug the charger into your phone, but only because it connects magnetically, surface to surface — isn’t really.
But the truth is wireless charging could be an even bigger boon to the billions of phone users in the developing world. Think of the Filipinos who traipse to the local mall to charge their devices after a typhoon takes out the power, and sit around waiting for a charger socket to be freed up? Imagine if they could just put their device on a big table, piled on other devices if there’s no space?
Or the commuter in Nairobi who could drop their phone in a bin when they get on and retrieve it when they get off, a precious few extra percentage points of charge better off?
Wireless charging isn’t just about cutesy lifestyles any more than wifi and mobile data has just been about empowering lounging hipsters. Wireless charging will eventually untether people from the tyranny of bad battery technology. It will create new businesses and boost productivity — especially from late afternoon to early evening, when surveys show many people run out of battery and the networks go quiet.
It won’t happen overnight, but it won’t happen at all until the Wireless Power Consortium, the Power Matters Alliance and the Alliance for Wireless Power get their act together and agree on a standard. So write to them, because you don’t want your grandchildren asking what you did to help usher in the wireless revolution.
