"There are three different primary energy-supply system classes which may be used to implement the hydrogen economy, namely, fossil fuels (coal, petroleum, natural gas, and as yet largely unused supplies such as shale oil, oil from tar sands, natural gas from geo-pressured locations, etc.), nuclear reactors including fission reactors and breeders or fusion nuclear reactors over the very long term, and renewable energy sources (including hydroelectric power systems, wind-energy systems, ocean thermal energy conversion systems, geothermal resources, and a host of direct solar energy-conversion systems including biomass production, photovoltaic energy conversion, solar thermal systems, etc.). Examination of present costs of hydrogen production by any of these means shows that the hydrogen economy favored by people searching for a non-polluting gaseous or liquid energy carrier will not be developed without new discoveries or innovations. Hydrogen may become an important market entry in a world with most of the electricity generated in nuclear fission or breeder reactors when high-temperature waste heat is used to dissociate water in chemical cycles or new inventions and innovations lead to low-cost hydrogen production by applying as yet uneconomical renewable solar techniques that are suitable for large-scale production such as direct water photolysis with suitably tailored band gaps on semiconductors or low-cost electricity supplies generated on ocean-based platforms using temperature differences in the tropical seas."

"Outwards from London, Glasgow, Amsterdam and Hamburg there radiated the lines - shipping lines, railway lines, telegraph lines - that were the sinews of Western imperial power. Regular steamships connected the great commercial centres to every corner of the globe. They criss-crossed the oceans; they plied its great lakes; they chugged up and down its navigable rivers. At the ports where they loaded and unloaded their passengers and cargoes, there were railway stations, and from these emanated the second great network of the Victorian age: the iron rails, along which ran rhythmically, in accordance with scrupulously detailed timetables, a clunking cavalcade of steam trains. A third network, of copper and rubber rather than iron, enabled the rapid telegraphic communication of orders of all kinds: orders to be obeyed by imperial functionaries, orders to be filled by overseas merchants - even holy orders could use the telegraph to communicate with the thousands of missionaries earnestly disseminating West European creeds and ancillary beneficial knowledge to the heathen. These networks bound the world together as never before, seeming to 'annihilate distance' and thereby creating truly global markets for commodities, manufactures, labour and capital. In turn, it was these markets that peopled the prairies of the American Mid-West and the steppe of Siberia, grew rubber in Malaya and tea in Ceylon, bred sheep in Queensland and cattle in the pampas, dug diamonds from the pipes of Kimberley and gold from the rich seams of the Rand."
