Your next e-book reader - powered by urine?
Imagine this. Next time you want to enjoy an e-book, it'll have to wait until you've relieved yourself. I get straight to the point: British scientists discovered a way to turn urine into electricity. I'm not saying this is the most elegant way to power a mobile device, but, well, can you think of anything cheaper?

According to Ieropoulos, a member of the team who has been working on this project:

Quote:
"One product that we can be sure of an unending supply is our own urine. By harnessing this power as urine passes through a cascade of microbial fuel cells (MFCs), we have managed to charge a Samsung mobile phone. The beauty of this fuel source is that we are not relying on the erratic nature of the wind or the sun; we are actually re-using waste to create energy.

So far the microbial fuel power stack that we have developed generates enough power to enable SMS messaging, web browsing and to make a brief phone call. Making a call on a mobile phone takes up the most energy but we will get to the place where we can charge a battery for longer periods. The concept has been tested and it works – it's now for us to develop and refine the process so that we can develop MFCs to fully charge a battery."
Here's a video describing the process in further detail:

I can just see how some conversations will end:

Mary: You spilled your drink on my ereader again!
Mark: Oh, I forgot to tell you that I just refilled the battery.

It'd give new meaning to the phrase, "pissing it all away" certainly.

Nope.

Kobo's going to have the longest battery life of all, because of all of their pissed-off users.

Of course the reader could double as a diagnostic tool. If the battery goes flat prematurely (i.e. needs recharging more often than usual) it's a sign of something wrong with the 'liquid additive.'
