Ovens (enclosed heating devices) – the advantage of an oven is that it is often insulated, so heat loss can be made minimal. The disadvantage is that only certain types of food can be cooked. A hob can in theory boil, fry, simmer. However it cannot bake bread.
We have explored regular low powered ovens, and alternatives like halogen ovens, bread makers, slow cookers and rice cookers. The latter deices tend to have an insulated chamber and electrically heat, generally quite slowly and at low power. Again, colleagues have suggested this would work well with solar reducing the total energy required – indeed even cooking slowly during the day, reducing the need for storage. Read more…
