I just returned from the Dawnbreaker technology commercialization conference. The conference is supported by the DOE, and is one of the oldest cleantech technology forums around.

Dawnbreaker had over 50 companies and 100+ strategics in attendance, and a number of very interesting technologies.

Among the more interesting in energy technology:

Alzeta Corporation was there showing a very interesting high efficiency burner. www.alzeta.com

A little company called InvenTek was showing off a unique battery structure, it was a ribbon Li-ion battery with a pancake coil design that exhibits very high power density. www.inventekcorp.com

CeraMem was showing off a restart of a very interesting technology in ceramic membranes for water purification. www.ceramem.com
