There would, of course, be some capital cost associated with heat exchange systems and forced circulation of warmed air, but this is usually the case anyway. Thermal wheels, even simple heat pumps, could be used to channel enormous amounts of otherwise “thrown away” energy into environmental control use. This comes back to my point about proper valuation of energy sources in terms of available work. (Table 1, page 19). Jacques Mr. Monson’s comments on allocation of losses, I wholly agree with. It is worth reiterating my point about the management objective, and the level at which the system decision is being evaluated—my diagram illustrates the point.

Particularly important is the use of computers in engineering design which improves the efficiency and effectiveness of plant, equipment and products. d) Not least is the impact that electronic computers are having on communication—ranging from inter-office to long-distance telecommunication. Efficient communication is essential in integrating the complex world of today. The very rapid increase in the power, and decrease in price, of electronic computing devices is having a major impact in most parts of modern society.

Arrangement of two or more materials which cannot easily be separated into their component materials without excessive expenditure of energy or with low yields. This wide definition would cover such products as steel-cored tyres, glass-reinforced plastics, bi-metals, motor car radiators, honeycomb structures, laminates, carbon filaments, ‘Hifill’, etc. In all such cases, their main reason for manufacture is that in service they contribute significantly to savings in operating energy or longer life.
