Traditional societies depended on biofuels and animate power from draft animals and human labor. The energy transition reduced biomass fuels to a globally marginal role, as fossil fuel extraction and electricity generation provided abundant and affordable energy. Consequences of this supply were magnified by conversions of fuels and electricity in new prime movers (first steam engines, and then internal combustion engines, electric lights, and motors). Indeed, they have nearly eliminated animate power, resulting in mechanization of agriculture and industrial production, in the rise of mass mobility, and in the deployment of electronic devices throughout the entire economy. Higher average per capita energy supply has been even more impressive when steady gains in conversion efficiency, and the resulting declines of energy intensities of products and services, are taken into account.

Natural Wind

The response of vehicles to the transient forces associated with gusting of the natural wind is assuming greater prominence. Total reliance upon natural gusts is unsatisfactory since these are unpredictable and unrepeatable. Major Continental manufacturers have for several years utilized gusts produced by multiple-fan installations, the power source being either electric motors or internal-combustion engines. The M.I.R.A. equipment is centred on a single Rolls-Royce Avon gas-turbine engine, the exhaust gases from which are directed across a roadway. Measurements have indicated that the gust profiles are similar to those encountered on motorways in respect of rise-time.

Detailed Nature

The possibility of control of circulation around aircraft wings and gas turbine blades by ejection of air from the aerofoil into the main stream has drawn attention to the manifold problem. Discharge velocity distributions along the length of the wing or blade must be uniform, and it is important that the detailed nature of the flow in the supply manifolds should be understood. The distributions of velocity in manifolds supplying multicylinder internal combustion engines, in gas burners and in manifolds supplying canal locks are other allied problems.
