Flash Education: Renewable Energy Overview

Click on the above screenshot to see the Flash animation. This interactive tells a story in pictures and words about three of the major types of renewable energy. The aim is to provide an accessible overview of hydro, wind and solar photovoltaic power generation.

Silicon doping in solar cells

Doped Silicon: This basic flash file I made illustrates how solar cells are made by adding tiny impurities of Gp III and GP V elements to silicon (GP IV element). [Use the keys at the bottom to navigate] The results in an electric field being formed across the p-n junction. Without the built-in electric field [...]

Model Pelton Wheel Hydroelectric Generator

In an earlier post I outlined an educational activity building a water-powered turbine (Pelton Wheel style) with milk bottle tops and plastic spoons. This was successfully trialled at the first Schoolgen Sister Schools Cluster Day in Spetember. Making the turbine (a linear to rotational kinetic energy converter) was the first stage in the creation of a working model of [...]
