Whereas the 19th century was the century of the steam engine and the 20th century was the century of the internal combustion engine, it is likely that the 21st century will be the century of the fuel cell. Full cells are now on the verge of being introduced commercially, revolutionising the way we presently produce power. Fuel cells can use hydrogen as a fuel, offering the prospect of supplying the world with clean, sustainable electrical power. The article discusses the history of fuel cells, fuel cells for NASA, alkaline fuel cells for terrestrial applications and PEM fuel cells. Fuel cell applications in transportation, distributed power generation, residential and portable power are discussed. The science of the PEM fuel cell and the direct methanol fuel cell are discussed. Benefits of fuel cells and obstacles to their widespread introduction are briefly outlined.

Spurred on by President John F. Kennedy's 1961 speech, which challenged America to place a man on the Moon before the end of the decade, NASA and its industrial contractors succeeded in doing so in July 1969. Delivering three astronauts to the vicinity of the Moon was challenge enough in those early days of the Space Age, but landing a crew on the lunar surface, supporting their science and exploration activities, and returning them to the relative safety of lunar orbit was a separate, equally difficult challenge. The solutions, in the shape of the Apollo lunar module and lunar roving vehicle, are the subjects of this article. Lunar module design and mass reduction are discussed. Power supply and power processing for the lunar module is discussed. The lunar rover is then described with particular emphasis on navigation, operation and performance.

Transformer oils based on polychlorinated biphenyls (PCBs) were widely used in industry up until the late 1970s, when it became apparent that PCBs build up in the environment and have the potential to be harmful. Bans on their use followed, so that many owners of electrical equipment containing PCBs face the immense task of replacing their units in time to meet national deadlines for phasing out these toxins. Turnkey replacement programmes are now available for PCB-filled transformers and capacitors that help their owners translate the cost of replacing their older units into long-term savings by installing more efficient, state-of-the-art equipment.

The history of X-ray equipment starts at about the same time as Marconi's work on wireless telegraphy and is interwoven with the development of the thermionic valve and filament lamps. This article starts with brief biographical notes on its discoverer, W. C. Rontgen, followed by accounts of its early use, particularly during the South African War (1899-1902). It traces the early evolution of X-ray tubes, including Coolidge's introduction of the heated cathode followed by further improvements before the mid 1930s.

From ancient times electricity in its various manifestations has been a subject of myth, mysticism and misunderstanding. Now comprehended by science, controlled and applied by engineers (if sometimes misused), its emergence in literature as a metaphor for vital attributes continues.

The Engineering Education Scheme forms part of The Royal Academy of Engineering's Best programme, which aims to attract, retain and develop outstanding young engineers, through its student, undergraduate and graduate programmes. Other schemes within the Best programme (which receives funding from the Gatsby Charitable Foundation) include Headstart, Year in Industry and the Engineering Leadership Awards.

As a note to an original presentation ("Modified nodal analysis: an essential addition to electrical circuit theory and analysis", see ibid., vol.11, no.3, p.84-92, 2002), this paper adds a further, final comment on the efficacy of modified nodal analysis (MNA) in handling multi-phase, coupled impedance networks typical of which are multi-conductor transmission lines and cables in which the electrical length is short so that the network elements are discrete lumped impedances.
