HIGH-SPEED PHONE CHARGING

I don't have much in the way of predictions for the future, but here's one I think would be a winner:

High-speed phone charging.

Your phone's on 3%, you need to leave the house but you also need to make an urgent call. Your battery pack's out of charge too, and all you can do is pick between being late, or that important call dropping out after the first minute. What do you do?

That seems like a common scenario for me. I'm not too great at forward planning. Anyway, all your problems would be over with the Instant Phone Charger. Just plug it straight in and your phone zips up from 3% to 93% in seconds. Boom, job done.

How would it work? Well it would have to deliver a massive amount of charge very quickly - so that will probably make it dangerous - it sounds dangerous. But it's not like we don't already have high voltage sockets in the house - they're dangerous enough aren't they? So it could be done, couldn't it?

Now, I'm not technically au fait with the obstacles that need overcoming here. Possibly there's the small issue that phone batteries might blow up. But surely that can be sorted? I mean some sort of failsafe that stops a high-speed charger working if the phone already has over 97% battery? I mean, come on boffins, it's been fifty-odd years since you put a man on the moon, surely this is easy!

Anyway. That's my thought for the day. I'm off out now.

At least, I would be...
