I just came across an interesting article on the web about new technology that can charge your phone using a tablespoon of water.. Amazing how the world evolves right out under our feet! One day you think that: Geez, everything ingenious possible has been thought of, and then out of the blue you are amazed by something you just never "thought of".
Basically this contraption allows anything chargeable through USB connections to be charged through it. All you need to do it put a tablespoon of water into it plug the USB cable into your phone and you're set to go. Anywhere in the world, anytime of day or night, given that you have some water at hand. If you don't you are probably screwed anyway...
At this stage it is still very expensive, $229 ( =/- R1750). So for now I'll just stick to my wall socket or car charger, thanks.
More details are avalable on the device's website:
There is also a cute "show-how" video on the site.
