SONY presents laptop batteries on fruit juice

Imagine the nearest future. Your laptop battery has run down again. That’s tough! But instead of looking for an AC adapter and outlet you …. open your fridge. No, you haven’t gone mad. The thing is your batteries now work on fruit juice.
Recently the Japanese newspaper Nikkei informed that SONY had presented such a tiny electric battery at the scientific congress in the USA. The new ‘biobattery’ of 5×10 inches in size and 10 milliwatt in power can be used in mobile phones, laptops and players. The charger for such a battery is filled with fruit juice as ‘petrol’. Which fruit juice should be used is not clear yet. 8 mL of juice is enough for approximately one hour.
The work on this unusual source of power have been going on in secret by the specialists from SONY for several years. In 2007 the present prototype model of 1.5 milliwatt power was developed; in 2009 — of 5 milliwatt power. Now the company considers its innovation worth presenting to mass consumers.
Scientists can make laptop batteries from ink and paper

Scientists from Stanford University used nanotechnology to create ultra-lightweight, flexible batteries and supercapacitors from ordinary paper. They just covered a sheet of paper with ink comprising carbon nanotubes and silver nanowires. And as a result they got a new storage device that can be used for production of innovative power supplies (laptop batteries, chargers for mobile phones, electric vehicles, etc.).
Capacitors can hold their charge for smaller period of time compared to batteries, but they can also be charged much faster. Professor Yi Cui (Stanford researcher) claims that used nanomaterials contain structures with a very small diameter, allowing ink to attach to fibrous paper. So it makes the paper batteries resistant to wear. Moreover, they can be recharged about 40,000 times (it’s incommensurably more than corresponding characteristics of lithium-ion batteries).
Yi Cui tried to create an analogous storage device form plastic earlier. But his new study shows that paper-based solution has greater prospects. This battery can be crumpled, placed into liquids (even acidic solutions!) without any damage to its performance.
Calculations show that paper with a kilogram of ink can power a 40-watt bulb for about an hour. It’s not an impressive result, but you should take into account that scientists are running their first experiments now. Be sure, after a couple of years your laptop battery will be much thinner and lighter in weight, allowing you to enjoy liаe without chargers and AC adapters for days, not hours.
Save Our Cords

When you have all your bags packed for a holiday or a business trip and are ready to leave for an airport, some small things are always missing – a toothbrush, an extra pair of socks or a phone charger. And a mp3-player charging unit. And a laptop adapter. And a pocket PC charger. And a camera charger or video camera charger or both.
When you are traveling by train and doze off unwittingly just to wake up and realize that this is your station and you must be getting off immediately, the first things you grab are a bag and hopefully a laptop. Chargers are always left in haste and are doomed to traveling miles and miles.
When you want to draw a portrait of your friend to impress all your guests with your digital drawing skills, but cannot find the cord that connects the computer and the graphics tablet, you probably feel upset and go on with your search until you find the cord lying peacefully under the sofa.
These things have probably happened to people who have invented a charger bag. To store things in one place is a universal idea, whether it is a CD-holder, a bookcase or a Tesco. But keeping all cords and chargers in one neoprene bag with 6 compartments is something new and probably convenient since the number of gadgets we own and want to own is constantly increasing.
