Accomodation can be designed to conserve and recycle heat using insulation and low level technology.


We generate heat when we live. When we eat some of the food is used to generate heat to keep our body temperature level.
Some of it is used to power the process of eating and digestion, some to power our thinking and the rest for movement.
The excess of heat is vented through our mouths and skin by evaporation etc.


This body heat is vented to the space we occupy and then vented to the atmosphere. We need to get rid of waste products in the process but we can recover the heat by passing the poluted air alongside a thin conductive layer, the other side of which there is a stream of air from the atmosphere passing into the room.


I successfully fitted such a system in a three bedroomed house and it was tested by scientists from two specialist companies. It was found to be more effective than double glazing but is best used in conjunction with all other forms of energy conservation.


We really do not need to heat our houses as our bodies give off enough heat for us to survive.

What about the Eskimos and igloos?

I understand that there is a building in Canada with no heating as it keeps its temperature level with sunlight and the body heat of the occupents.


Low heat light bulbs do not conserve energy. To keep warm people need the heat that is given off by traditional lighting including candles and the matches that light them.

We need efficient insulation and heat exchangers.


Waste products degrade producing usable energy that can be captured and stored. This is simple technology and can be put into effect using the containers that we normally discard to landfill.
