{{CZ:Featured article/Current}}
The '''[[Crystal Palace]]''' was a glass and iron structure built to house the [[Great Exhibition of the Industry of All Nations]] in [[Hyde Park]], [[London]], in 1851. After the Exhibition, it was moved and expanded and rebuilt on [[Sydenham]] Hill overlooking London, where it enjoyed a second life from 1854 until a horrific fire destroyed it in 1936.
 
The Crystal Palace is a significant structure in many ways: it was the first structure of its size assembled from [[prefabrication|prefabricated]] parts; its system of horizontal trusses has since become one of the most widely-used construction methods in the world; it was at the time the world's largest enclosed open-air structure; and its success inspired the building of similar structures around the world, from the [[New York Crystal Palace]] in [[New York City]] to the [[Kibble Palace]] in [[Glasgow]]. It also symbolizes technological prowess and imperial power of enormous historical and cultural significance. In its second incarnation in Sydenham as a [[suburbs|suburban]] pleasure palace it drew crowds away from the central metropolis and was also a concert hall, famous for its performances of [[George Frideric Handel|Handel]] with a massed orchestra, choir, and the Palace's enormous organ; a recording of such a performance in 1888 is the earliest known recording of live music in existence. Its exterior park, with fountains, terraces, and an outdoor exhibition of life-size [[dinosaur]] sculptures, was also highly influential. It also housed, from 1933 to 1936, the experimental studios of the [[John Logie Baird|Baird]] [[History of television|television]] company, which made regular [[short-wave]] broadcasts from its South Tower.<font size=1>[[Crystal Palace|['''more...''']]]</font>

Featured Article: Nuclear power reconsidered

After decades of failure to slow the rising global consumption of coal, oil and gas,[1] many countries have proceeded as of 2024 to reconsider nuclear power in order to lower the demand for fossil fuels.[2] Wind and solar power alone, without large-scale storage for these intermittent sources, are unlikely to meet the world's needs for reliable energy.[3][4][5] See Figures 1 and 2 on the magnitude of the world energy challenge.

Nuclear power plants that use nuclear reactors to create electricity could provide the abundant, zero-carbon, dispatchable[6] energy needed for a low-carbon future, but not by simply building more of what we already have. New innovative designs for nuclear reactors are needed to avoid the problems of the past.

Fig.1 Electricity consumption may soon double, mostly from coal-fired power plants in the developing world.[7]

Issues Confronting the Nuclear Industry

New reactor designers have sought to address issues that have prevented the acceptance of nuclear power, including safety, waste management, weapons proliferation, and cost. This article will summarize the questions that have been raised and the criteria that have been established for evaluating these designs. Answers to these questions will be provided by the designers of these reactors in the articles on their designs. Further debate will be provided in the Discussion and the Debate Guide pages of those articles.

Footnotes

  1. ↑ Global Energy Growth by Our World In Data
  2. ↑ Countries, organizations, and public figures that have reconsidered their stance on nuclear power are listed on the External Links tab of this article.
  3. ↑ Pumped storage is currently the most economical way to store electricity, but it requires a large reservoir on a nearby hill or in an abandoned mine. Li-ion battery systems at $500 per KWh are not practical for utility-scale storage. See Energy Storage for a summary of other alternatives.
  4. ↑ Utilities that include wind and solar power in their grid must have non-intermittent generating capacity (typically fossil fuels) to handle maximum demand for several days. They can save on fuel, but the cost of the plant is the same with or without intermittent sources.
  5. ↑ Mark Jacobson believes that long-distance transmission lines can provide an alternative to costly storage. See the bibliography for more on this proposal and the critique by Christopher Clack.
  6. ↑ "Load following" is the term used by utilities, and is important when there is a lot of wind and solar on the grid. Some reactors are not able to do this.
  7. ↑ Fig.1.3 in Devanney "Why Nuclear Power has been a Flop"
