Tom Vales Experiments

High Frequency Electricity

This experiment was done by science prof Tom Vales. He spoke and demonstrated different objects such as the sterling engine, Peltier Junction and the Mendocino motor.

1.    The Stirling Engine

Is 80% efficient. Is a hot air engine and it works by having hot air or other gases. It uses a displacer, and is set at different temperature levels so there could be a net conversion of heat energy so it can mechanically work.

How it works?

In this case Tom Vales used one carton cup, has 2 plates, a upper plate, and a lower plate. It’s 200 years old. Its sitting on a cup of hot water and it has a 4 degree Celsius.

The bellow picture is an example of a stirling engine, although it is not based of two of such as Tom Vales used.

2.     The Peltier

The Peltier effect was a discovery Jean Charles Athanase Peltier made when he was investigating electricity.

He joined copper wire and bismuth wire together and connected them to each other, then to a battery. When he switched the battery on, one of the junctions of the two wires got hot, while the other junction got cold.

In this experiment by Tom Vales, Tom used 2 cups and two metal tags. One piece of metal is in cold water and are piece of metal in hot water. It generates a sendi-cunducted type of energy.

The biggest use for this for example is in a computer, but it gets severely hot.

3.    Mendocino Motor:

The person who invented this was from Mendancine California. The motor consists of a four-side rotor block in the middle of a shaft. The rotor block has two sets of windings and solar cell attached to each side.

The shaft is positioned horizontally and has a magnet at each end.

There is an additional magnet that sits under the rotor block and provides a magnetic field for the rotor.

When light strikes one of the solar cells, it generates an electric current thus energizing one of the rotor windings.

This produces a magnetic field, which interacts with the field of the magnet under the rotor. This interaction causes the rotor to turn.

The light hits the solar cell and hits the light and magnet. It turns 90 Celsius and it floats.

There’s notification, it has a use as a teaching tool, and you have solar energy, magnets. They can be done as big as you want.

4.    Piezo Electic Effect

This is a type of electric motor based upon the change in shape of a piezoelectric material when an electric field is applied.

The elongation in a single plane is used to make a series of stretches and position holds.

There are small piece of small crystals that has wires, and has a button.

It will make high voltages in the other direction. It uses as a radiogram meter in which it generates sparks.

Overall, Tom Vales experiment where grate, such an amazing way of experiencing how we can create electicity in so many different ways.
