ZigBee 101

Written by Allen Nogee Tuesday, 01 September 2009 09:00
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.
