Introduction

Who I am

Today we will be

Talking about the Invention of the Light Bulb

Seeing our own bulb come on

Talking about Innovation vs. Invention

Learning a little about Energy and Electricity

I'll be asking YOU a lot of questions

I'll be answering your questions too


4/20

Objectives

After Today's Talk and Demonstrationyou should:

Understand the difference between innovation

and invention Have an appreciation for the history of the

development of the Light Bulb

Know a little more about how a light bulb works

Have an appreciation for some of the energyissues YOU will face in your futures.

Have enjoyed yourselves and want to continueyour education!

Who Invented the Light Bulb?


9/20

Sir Humphrey Davies

DemonstratedIncandescence of aPlatinum Filament in

open air in 1802 Used the most

powerful battery thenin existence

Further experimentslead to moreknowledge of

electricity

Joseph Swan

First experiments in1850 usingcarbonized paper

filaments in a limitedvacuum

December 18th 1878demonstrated a

carbon filament bulbto the NewcastleChemical Society

British Patents 1880

Electric Lamps October 22nd 1879

first successfulCarbon Filament

Other Inventionsinclude thePhonograph and

Motion Pictures


12/20

So Why Edison?

Others Came First

At least 22 people arerecognized by

historians as havingdeveloped bulbs

Edison didn't workalone either (don'tforget the Muckers)


13/20

Invention vs. Innovation

Invention

The first occurrenceof a new idea

Not all Inventions arepractical, useful, orneeded

Innovation

The first occurrenceof taking an idea and

making it a workingreality

Put another way:Solving a problem ina useful and effectiveway
