Energy saving technology


DMA: Design and make a hot food product that is energy efficient in both sourcing and preparation.

FPT: Investigate a number of different methods of making an energy-efficient hot meal. Consider the cooking technology, source of ingredients and the recipe.

Product analysis:
Make your own three-stone fire and see how long it takes to boil a litre of water in a pot.

Time how long it takes to boil a litre of water on a gas or electric cooker. How does it compare with using a three-stone fire? Which is quicker? By how much?

FPT: Write a specification for a UK stove or cooker that can be used outside and which is better than a three-stone fire. You will need to decide on the intended market and use.

Research: Make a note of all the energy (e.g. kettle boiled for 4 minutes, carrots cooked on medium gas for 12 minutes etc) used for a week in cooking and heating water for drinks in your household. Share your list with a partner and together try to think of ways in which energy could have been saved during the week.

Product analysis: Conduct a website or shop-based search for different types of stove that can be used for cooking outdoors. You might try www.parkcrown.co.uk/frame.htm or www.thebbq.co.uk

Other subjects: Talk to your teacher or parent about making a stove of your own from clay. You can get details of stove dimensions and manufacture from Practical Action at the address given in the ´Where to Find More´ cog.
