I’m struggling to define my brand. Am I the writer who can learn enough about lithium-ion battery chemistry to write about it in understandable English? Or am I the author trying to change the world by spreading the message of environmental sustainability and smarter use of materials?

In October, I had the opportunity to speak to three very different audiences: 1) semiconductor packaging industry executives and engineers; 2) members of a synagogue who are part of the congregation's "green team"; 3) university students enrolled in an environmental health seminar.
