ZigBee 101

Editor's Note: Allen Nogee (an active CT member, using the nick ano) has written
a great article for CocoonTech about the current state of ZigBee, specifically
focusing on home automation, explaining what it is all about. Hopefully this
will clear up some confusion, and make you guys as excited as I am about the
potential of ZigBee. If there are any questions you don't see answered, please
post them in the discussion thread, which will be linked at the bottom of this
article within minutes of the article going live.

New Battery
Ceramatec says its new generation of battery would deliver a continuous flow of 5 kilowatts of electricity over four hours, with 3,650 daily discharge/recharge cycles over 10 years. With the batteries expected to sell in the neighborhood of $2,000, that translates to less than 3 cents per kilowatt hour over the battery's life. Conventional power from the grid typically costs in the neighborhood of 8 cents per kilowatt hour.

Songdo Opens its Doors
The
first phase of the Songdo IBD international city
celebrated its grand opening on August 7, 2009. This
master planned "ubiquitous" metropolis is being
developed on 1,500 acres of reclaimed land in South
Korea along Incheon's waterfront by Gale International
and Korea's POSCO E&C. It promises to be a model of
sustainable, city-scale development and innovation.
When complete, Songdo IBD will
encompass 100 million sq. ft., including forty-five
million of office space, thirty million of residential
space, ten million of retail, five million of hotel
space and ten million of public space. By 2015, it will
house 65,000 residents and 300,000 workers. It will be a
city where technology, resources and innovation all come
together to create the ideal environment.
