YOU CAN NOW CHARGE YOUR PHONE BY SIMPLY SHOUTING AT IT

This might sound ridiculous, but it's actually true.
Most phone batteries die when you want to make important calls, but shouting
at your Phone out of frustration might be the right option a new gadget could soon mean your screams won't be in vain.



Their prototype device, which is about the size of a mobile phone, uses zinc oxide to convert vibrations caused by sound into electricity.
The invention was inspired by previous research at Queen Mary University of London (QMUL), which found playing pop and rock music improved the performance of solar cells.

This was because the sound vibrations triggered the movement of material in the solar cell that caused it to improve efficiency by up to 40 per cent.
Developing this research further, Nokia worked with the QMUL team to create an energy-harvesting prototype that could be used to charge a mobile phone using everyday background noise.

In order to make it possible to produce these nanogenerators at scale, the scientists found innovative ways to cut costs in the production process.
Firstly, they developed a process whereby they could spray on the nanorod chemicals - almost like nanorod graffiti - to cover a plastic sheet in a layer of zinc oxide.
When put into a mixture of chemicals and heated to just 90C, the nanorods grew all over the surface of the sheet.
Secondly, gold is traditionally used as an electrical contact, but the team were able to produce a method of using cheap and cheerful aluminium foil instead.
The final device is the same size as a Nokia Lumia 925 and generates five volts, which is enough to charge a phone.
'Being able to keep mobile devices working for longer, or do away with batteries completely by tapping into the stray energy that is all around us is an exciting concept,' said Dr Joe Briscoe from QMUL.

What do you think? Cool  8) or Whack? :P :P

You do know that it's real. Where you get the information from it.
