Green technology is red hot, and it had its own fashion show last week in New York. On display were an HP printer made from corn, backpacks and laptop bags with solar panels to charge electronics, and environmentally friendly cell phones. These were just a few of the items featured at the first Greener Gadgets Conference.

The conference drew between 300 and 400 people and featured speakers from several top tech companies and organizations.

Nokia showed off its 3110 Evolve, which is made partly of post-consumer materials and is 80% recyclable. The mobile phone company also showed off a prototype ecosensor, which looks like a watch, can be worn on the wrist, and works with a cell phone to give information about the atmosphere and weather, as well as readings on vital signs. The device works with a phone and is charged by solar rays.

Hewlett-Packard research and development displayed a printer made from corn, a bioplastic the company experiments with. The printer was part of a large workstation display with several features to save energy and reduce environmental impacts. The company’s rp5700 desktop PC, unveiled last year, includes an 80% efficient power supply. The long lifecycle desktop lasts five years, instead of 18 to 24 months, and is made of at least 90% reusable or recyclable materials.
