The "safety lamp" invented by Humphrey Davy in 1815 utilised the cooling effect of metal gauze to prevent the flame of a candle or oil lamp (essential for illumination in mines) from passing through such a screen. It is therefore rendered unable to ignite any potentially explosive mixture of air and methane in the atmosphere surrounding…

This paper describes an exercise completed by sixth form college students to compare the power output from a local coal fired power station with the potential power output from renewable sources including wind farms, solar farms, and the proposed Mersey Tidal Barrage scheme. (Contains 1 figure, 1 table, and 3 photos.)

The energy losses and output of a modern power plant using coal and fuel oil are quantitatively presented. (CP)

Describes a three day activity in which students divide into groups, each group arguing for the construction of a power plant using coal, oil or nuclear energy. (CP)

Energy as an abstract concept is discussed, and the effect of using inappropriate language in the teaching of energy is considered. The storage of energy is illustrated using gravitation and the combustion of coal as examples. (CW)
