As someone who uses lots of trains, the news that Dr Sang-Woo Kim of the Sung-Kyunkwan University in Seoul, South Korea has discovered a way of charging mobile phones by talking into them strikes me as more of a threat to Western civilisation than anything the late Osama bin Laden could have dreamt up.
At the moment, the technology can convert 100 decibels (about the same level as a busy road) into 50 millivolts of electricity, which isn't enough to charge a phone.
But give it time, and then won’t using public transport be fun? If, like me, you're irritated by sitting near an overly-loud, mind-numbing ‘I’m on a train . . . hello? . . . no, I said I’m on a train . . . ’ conversation, how's travel going to be remotely tolerable when there's a carriage full of half-wits screaming into their Nokias because they forgot to charge them up overnight?
Forget al-Qaeda, the electronics department of Sung-Kyunkwan University needs flattening.
Now!
