What do you think about our new web site?

Love it, indeed
Really good solution
Same as old one
The old one was better
This is a new option

Quote of the day

People say we're running out of energy. That's only true if we stick with these old 19th century technologies. We are awash in energy from sunlight.

Two innovations for on-the-go mobile-device users seeking a quick charge are in the works: Starbucks plans to install wireless charging devices in all of its stores; and a new battery design could enable rapid charging of lithium-ion batteries in ten minutes.

 
Starbucks stores will have “Powermat Spots”, designated areas on tables and counters where customers can place their compatible device and charge them wirelessly. The system uses inductive coupling, which can charge nearby devices.
 
Some Starbucks stores in Boston and San Jose offer Powermat today, with San Francisco next. Starbucks is planning some 100,000 devices in its 7,000-plus stores, says the Washington Post/Bloomberg. Track the rollout here.
 
Meanwhile, researchers at the University of California, Riverside Bourns College of Engineering have developed a new battery anode design for rechargeable lithium ion batteries that could allow charging in 10 minutes instead of hours.
 
It uses silicon, whose total charge capacity is 10 times higher than commercial graphite-based lithium ion battery anodes. That could result in a 63 percent increase of total cell capacity and a battery that is 40 percent lighter and smaller, the US Riverside researchers say. They’re developed a novel structure consisting of cone-shaped carbon nanotube clusters decorated with 3D silicon.

In the world of technology this could look as a minor issue. However, practical aspects of recharging a smart phone have a huge impact considering that so many people have the device and rate a battery life as number one feature. Well done Starbucks Reply
