back to article LIVE, my beauty, LIVE! Nokia revives dead phone with LIGHTNING powered Frankencharger

It sent a DeLorean back though time, brought Frankenstein's monster to life and nearly got Benjamin Franklin killed, but now the power of lightning has been harvested to charge a mobile phone. White-coated boffins at the University of Southampton were co-opted by Nokia to catch a 200,000-volt spark and step it down before …

The researcher looks..

A little disturbed and out of it.. I wonder if he's making recreational use of his experiments!

A/C cause I live near Southampton and I don't want a 3am visit from "Dexter".

Re: The researcher looks..

I don't know, I thought he looked a trifle pissed off that the proper research he'd like to be doing has been hi-jacked and turned into a publicity stunt by a dying mobile phone brand, probably in return for some much-needed funding. But that's just my interpretation...

Not a/c because, although I also live near Southampton (hey neighbour!) I don't think Dexter has my address. Oh hang on, there's the door...

hey neighbours

I live near Southampton too, I'm not worried though as Dexter will get you 2 first...

Re: real lightning is DC

More like half-wave rectified AC in the way it comes on. Call it momentarily switched DC.

Re: real lightning is DC

TBH I had to think about that quite hard before I posted. However, as all the charge goes in one direction, I'm pretty sure lightning can count as DC. Admittedly, a lightning bolt has considerable high frequency AC components in it, but every DC signal is switched at some point, e.g. when it was switched on, so any DC signal has frequency components in it if you look for long enough...

Whatever, get hit by lightning and you will shake all night long, AC or DC.

Re: real lightning is DC

It's DC but no AC component, just fluctuations. Alternating component implies a current polarity reversal.

I think the concept you are trying to describe is that DC has bandwidth, owing to the fact that it was switched on, and at some time will be switched off.

Of course the demo is pure b0ll0cks. Any sensible filtering arrangement will smooth the current fluctuations. What's nice is that the phone isn't destroyed by the RF field. Perhaps that makes the point for metal cases.

This is how Apple's Lightning connector should really behave. Or maybe it does, if those zapped Chinese folk were using a genuine one.

Might be a slight difference between the output of a 200kV transformer and lightening strike though. You know, the odd few orders of magnitude. Much easier to take that continuous 200kV transformer output and step it back down again - after all, that's done on an everyday basis by electricity grids around the world.

Sounds like some pointless advertising?

Also does this mean you can only charge your phone outside in a storm - sounds a tad dangerous to me.

BOFH time

Let the boss blow up his mobile phone by assuring him that the cattle prod (beefed up) is the latest charger. Ultra-fast on the go for busy executives who cannot afford to wait for their phone to charge

Darn, still no BOFH icon.

Oh well

That scientist looks pissed off.. really did not sound happy to be doing this research with Nokia...

'first step' and they charge a phone? I doubt it... more likely Nokia offered cash and he had to do this to get it...

On the plus side, power from lightning is a great idea!

"It sent a DeLorean back though time"

If you watch the film very carefully, you'll find that lightning send the DeLorean *forward* through time, not back. ("Back" was powered by stolen plutonium if memory serves, and at the end by "Mr Fusion".)

Pay attention now...

"If you watch the film very carefully, you'll find that lightning send the DeLorean *forward* through time, not back. ("Back" was powered by stolen plutonium if memory serves, and at the end by "Mr Fusion".)"

And if you watch the sequel you will note that lightning does indeed send the DeLorean back in time to the wild west

Really? I thought is was at the end of BTTF2 which setup BTTF3 which was set the old wild west. If you are correct time must run backwards for you. If that's the case you must have a face like the Cat from Red Dwarf after every trip to the toilet!

Shame they didnt...

Let Balmer hold the phone whilst it was zapped - would be far more entertaining...

Lightning testing

Being slightly serious for a moment, there used to be a UK company that made lightning suppressors for telecoms and the like. They attempted to sell them to the railways to protect the data lines on electrically controlled signal boxes, but were told that lightning had never been a problem.

God* was obviously listening and not too keen on hybris, because shortly after she zapped Westbury signal box with a massive bolt and did about £20 million worth of damage.

My point, such as it is, is not only don't try this at home but don't try it in the office either, unless you really, really know what you are doing. And have big ceramic gas-filled surge suppressors.

*I don't believe in God, but the God I don't believe in is female, detests patriarchy, and has an evil sense of humour, to rework Catch-22.
