For pt.II see ibid., vol.10, no.6, p.244 (1979). Attempts to assess the very important role that may well be played by earth heat in the world energy strategy of the future. Rock fracturing methods are discussed and applications considered

Reviews batteries suitable for electric vehicles and power storage, whether in existence or under development. Criteria for these applications are considered

Electronic speckle pattern interferometry can provide high-speed, real-time holography for industrial research and inspection. This article discusses its basic principles, modes of operation and applications, and finally tries to assess its future importance for industry.

For pt.I see ibid., vol.10, no.6, p.266 (1979). Progress in laser and millimetre wave technology, combined with the need for a better understanding of environmental systems and living organisms for the Earth's resources and pollution surveillance, is leading to greater interest in environmental remote sensing systems. This article considers the methods of determining the molecular chemical/biological surface composition

Metallic glasses are metals with a noncrystalline structure. They have unusual and unexpected properties, such as high tensile strength, high electrical resistivity, and magnetic softness. This article considers these and other properties and suggests possible technological applications
