  • A voltaic pile battery is used to light an LED.  This type of battery was the first chemical battery and was invented by Alessandro Volta in 1791.  This battery consists of two different metals.  Here copper United States pennies manufactured before 1982 were used and the source of Zinc was zinc coated washers.  Cotton paper is placed between the coins and wetted with an acid.  In this experiment the acid used was 5% acetic acid from household vinegar. The vinegar is the electrolyte<br />
Unlike the Leyden jar, the voltaic pile produces a continuous electricity and stable current. The order of the stack is copper, zinc and then paper.  This pattern is repeated throughout the battery.

  • A Synthetic quarts crystal that is lab grown.  This crystal will be cut into sections that will be manufactured into optical components and electrical quartz crystal oscillators. Quartz creates an electrical signal with a very precise frequency that is used to provide a stable clock signal to the rest of the circuit.

  • The corona discharge from a Wimshurst machine.  This machine glows as the high voltage from the static electric generator ionized the surrounding air.  This image was taken with a modern camera able to photograph at very low levels of light.  This effect is bright enough to be observed with human eyes in a very dark room.

  • Thermogram of an electrical substation.  The substation houses a number of transformers that convert line voltage into the correct voltage for homes to use. The different colors represent different temperatures on the object. The lightest colors are the hottest temperatures, while the darker colors represent a cooler temperature.  Thermography uses special cameras that can detect light in the far-infrared range of the electromagnetic spectrum (900?14,000 nanometers or 0.9?14 µm) and creates an  image of the objects temperature..

  • Thermogram of electrical wires on a telephone pole connected to a transformer. The different colors represent different temperatures on the object. The lightest colors are the hottest temperatures, while the darker colors represent a cooler temperature.  Thermography uses special cameras that can detect light in the far-infrared range of the electromagnetic spectrum (900?14,000 nanometers or 0.9?14 µm) and creates an  image of the objects temperature..

  • Thermogram of resistive heating of a wire.  The large amount of current going through the wire is responsible for heating up the wire. .  The different colors represent different temperatures on the object. The lightest colors are the hottest temperatures, while the darker colors represent a cooler temperature.

  • This is an x-ray of a hand crank Flashlight.  The flashlight has no batteries and is activated by pressing the handle.  The handle is connected to a generator that creates electricity for the light bulb.  This is an example of an environmentally friendly design.  The flashlight does not consume chemical batteries.
