The Light Bulb Box is a simple demonstration tool to show the difference in energy use between three types of bulbs--incandescent, compact fluorescent, and light emitting diode. It can also demonstrate vampire energy.

If you are interested in having a demonstration of the box in your class or club, let me know. I am available to come to classes Monday, Wednesday, or Friday most weeks and I can tailor the presentation to the age group and time available--everything from "Hey, look at this cool box that does THIS" to more in-depth discussions about ways of meeting needs, energy terminology, the history of light, etc.

Showing the different wattage of various light bulbs and talking about the history of artificial light with Ms. Dobbertin's second grade class at San Miguel.

This video and ones like it have "gone viral" on the internet, showing how a simple low-tech solution can bring light into dark inside spaces. Obviously this light bulb only works when it is bright outside, but it still helps very poor or energy-starved areas enjoy light in dark spaces for free.

Check out this interesting graphic that compares 6 different fuels for what it takes to power one 100 Watt lightbulb for one year. 714 pounds of coal, 143 pounds of natural gas, 2 hours and 20 minutes of a 1.5 megawatt wind turbine running at 25% capacity . . .
