Understanding Science For Motorhomers - Electricity: Five Basic Concepts

Peter Eyland a Motorhomer & a Scientist talks about five basic concepts behind Electricity - namely Charge, Current, Potential Difference, Resistance & Power. He also covers the units to describe these electrical quantities - namely Coulombs, Amps, Volts, Ohms and Watts. Information for informed Motorhomers.

Understanding Science For Motorhomers - Batteries, Inverters & Fuel Cells

Useful talk about the science behind Batteries, Inverters & Fuel Cells. He covers how they are made, and their different uses in Motorhomes. Also covers some newer technologies.

Battteries, Inverters & Fuel Cells

Motorhomer Electrical Safety Basics

Talk covers Australian standards for electrical cables, electrical do's and don'ts, amph-Fibians devices, a quick quiz for electrical safety, residual current devices & switches etc. Essential information for all Motorhomers.

The Science behind Solar Panels & Sunlight

This talk covers the science behind Solar panels, how they are made, semi conductors, thin silicon films, how impurities are added, PN-junctions, semi conductors, Solar controllers, Maximum Power Point tracking (MPPT). It covers all scientific aspects of Solar Panels or Photovoltaics (PV), Sunlight, Peak Solar hours etc. How if you put "Light IN you get Current OUT". How solar works.

The Science behind Light, Lighting & Artificial Leaves

Peter talks about the science behind light, solar insolation, irradiance & illuminanse. How different types of lighting are made, and how they perform. What is most suitable to Motorhomers. He also covers the science behind LEDs (Light Emitting Diodes), Artificial Leaves, and other future technologies such as Organic LEDs. Explains how you put "Current IN and you get Light OUT". Corrects some basic misconceptions about lighting for Motorhomers.

Cloning, Stem Cells and Genetic Engineering

Peter Eyland takes you through the scientific terms of cloning, stem cells and genetic engineering. He does NOT make any ethical or religious conclusions or statements in the talk. He does talk about popular culture and does cover some misconceptions behind the science.

See Peter's Cloning Slideshow page.

Famous Women in Astronomy

Slideshow on Women in Astronomy. Many women were instrumental in radio astronomy and observational astronomy. Very few people have even heard of them. Includes Australian and overseas examples of these "unsung heroines".

See Peter's Women in Astronomy Slideshow page.

Workshop: "Starry Starry Night"

Peter takes small groups (or large) into a dark field and shows you what to see in the night sky tonight. He demonstrates how to set up two telescopes, and shows you a number of astronomical bodies eg the moon, nearby planets, a number of recognisable stars & constallations.

Peter also demonstrates a number of iPad Apps (applications) to help you identify star, planets, satellites etc. Great beginners workshop, very popular (no charge).

Workshop. (Hands on practical not a slideshow.)
