Introducing the Latest High Tech Invention…The Leaf

General Purpose: To inform
Specific Purpose: The purpose of this presentation is to inform the audience of the invention of the Artificial Leaf and its potential applications. Introduction
I. Efficient and affordable if not free “green energy” is something sought after by scientists, eco-conscious individuals, organizations, and consumers alike. A. Some of these concepts are already well known. Solar, wind, and water driven technologies all seek to achieve these goals, but often fall short of the mark because the technologies behind them are usually either not yet efficient enough, or the cost of the equipment is simply not affordable.

II. If I told you that a new environmentally friendly technology has been developed that can efficiently produce “green energy” would you want to hear about it? A. What if I told you that it was cheap enough for developing villages and communities to be able to afford it? B. What if I told you that this new technology could power your home for 45 continuous hours on a gallon of tap water?

III. Today we’re going to talk briefly about a recently revealed new technology, being called an “artificial leaf” A. First, we’ll talk about what the artificial leaf is. B. Then we’ll discuss how it works.

C. Finally we’ll talk about what this may mean for our future.

Body
I. MIT chemist, Daniel Nocera recently announced at a press conference held at The American Chemical Society, a new breakthrough in technology that allows for the economical and eco-friendly production of energy. It is being hailed as a milestone in the drive for sustainable energy. He calls it an artificial leaf. “A practical artificial leaf has been one of the Holy Grails of science for decades,” said Daniel Nocera, Ph.D., leader of the research team. “We believe we have done it.

A. What is an artificial leaf?
1. It is a solar cell covered with catalysts made of...
