__NOTOC__


'''Tux''' the [[penguin]] is the official logo and cartoon mascot for the [[Linux]] computer [[operating system]]. First drawn in 1996 by Larry Ewing, the fun-loving character has a special place in many people's imaginations, both inside and outside of the global Linux community.


====Quest for a Linux logo====
Tux originated from a discussion on the "Linux kernel" [[mailing list]].  On May 1, 1996, early Linux contributor Matt Hartley began a thread entitled "Linux logo", which included an image by David Christiansen showing the planet Earth as seen from outer space, along with the captions "LINUX" and "Take your computer to another dimension." At one point, [[Linus Torvalds]], the software engineer behind Linux, had casually mentioned his fondness of penguins, and list-users began to rally around the idea.

The present global financial crisis, which we are provisionally calling '''the [[Crash of 2008]],''' is described by former Federal Reserve Bank Chairman [[Alan Greenspan]] as being a "once in a century credit  tsunami". It began with the American  [[subprime mortgages crisis]], which spread rapidly to affect  financial organisations  throughout the world and is now contributing  to the severity of the developing  [[recession of 2008]]. Governments in the United States and Europe have responded to the crisis by providing unprecedented amounts of financial support to their banking systems, and are considering measures to strengthen their regulation.

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"
