has debuted a new device for these users that connects to a bicycle
and charges a mobile phone. The Nokia
charger uses a dynamo that is powered by the spinning of the
bike wheels. Nokia claims that the rider will need to maintain about
4 mph forward speeds to charge the device.
from Nokia, it might come as a surprise that the charger will work
with any handset that uses a 2mm charging jack."Bicycles
are the most widespread means of transport in many markets around the
world, so this is just one more benefit to be gained from an activity
people are already doing," said Alex Lambeek, Nokia vice
president in a statement."The charging device promises
to produce enough power for about 28 minutes of talk time or 37 hours
on standby if the rider travels at 6 mph for at least ten minutes.
The charger also comes with a handlebar mount holder to secure the
phone while charging.
charging kit will launch globally by the end of 2010 and the cost
will vary depending on where it sells. Nokia will offer the charger
in Kenya to start with at a price of about 15 euros.

In the prototype of the single-pole electric starter (finished between 1852 and 1854) both the stationary and the revolving parts were electromagnetic. He formulated the concept of the dynamo at least 6 years before Siemens and Wheatstone but didn't patent it as he thought he wasn't the first to realize this.
