Submission + - China's new space reactor 'will be 100 times more powerful than Nasa's' (scmp.com)

Hmmmmmm writes: China is developing a powerful nuclear reactor for its moon and Mars missions, according to researchers involved in the project. The reactor can generate one megawatt of electric power, 100 times more powerful than a similar device Nasa plans to put on the surface of the moon by 2030. The project was launched with funding from the central government in 2019. Although technical details and the launch date were not revealed, the engineering design of a prototype machine was completed recently and some critical components have been built, two scientists who took part in the project confirmed.

In his last days in office, former United States president Donald Trump signed an executive order to accelerate the application of nuclear power in US civilian and military space programmes. Nasa recently opened a bid to private contractors to develop a 10-kilowatt nuclear fission device that could support a sustained human presence on the moon within a decade.

Russia has announced a plan to launch a huge spacecraft powered by TEM, a megawatt-sized nuclear reactor, before 2030. The nuclear energy would allow the spacecraft to operate for more than a decade in the Earth’s lower orbit while carrying out additional missions to the moon or beyond.
The European Space Agency has launched a similar project, Democritos, with a 200kW space reactor to be tested on the ground by 2023.

The first nuclear power device in orbit was SNAP-10A launched by the US in 1965. The device produced 500 watts of electric power for over a month before its permanent shutdown.

My charger has a light that shows when the battery is charging. When the battery is charged, the light turns off.

The charger light turns on when the TV or music is loud. It switches off not quite as fast as a scope would show activity, but soon enough to know that something draws more current when there is significant audio input.

I bet a phone with a dead battery could be used to track audio spying pretty easily.

I love your point about storage. Some apps queue their data for upload on reconnect.

Submission + - NASA Seeks Help of Amateur Radio Community (nasa.gov)

clm1970 writes: In another conventional use for an arguably unconventional hobby given the technology of 2011 NASA is requesting the help of Amateur Radio or "ham operators" to help listen to a beacon signal of a nano-satellite. Many say the hobby is dying but for every "death knell" it seems another application brings it back to life to prove its usefulness.

Submission + - End the Ethanol Insanity

theodp writes: It's now conceivable, says BusinessWeek's Ed Wallace, that the myth of ethanol as the salvation for America's energy problem is coming to an end. Curiously, the alternative fuel may be done in by an unlikely collection of foes. Fervidly pro-ethanol in the last decade of his political career, former VP Al Gore reversed course in late November and apologized for supporting ethanol, which apparently was more about ingratiating himself to farmers. A week later, Energy Secretary Steven Chu piled on, saying: 'The future of transportation fuels shouldn't involve ethanol.' And in December, a group of small-engine manufacturers, automakers, and boat manufacturers filed suit in the U.S. Court of Appeals to vacate the EPA's October ruling that using a 15% blend of ethanol in fuel supplies would not harm 2007 and newer vehicles. Despite all of this, the newly-elected Congress has extended the 45 cent-per-gallon ethanol blending tax credit that was due to expire, a move that is expected to reduce revenue by $6.25 billion in 2011. 'The ethanol insanity,' longtime-critic Wallace laments, 'will continue until so many cars and motors are damaged by this fuel additive that the public outcry can no longer be ignored. Adding an expensive, harmful, useless filler to gasoline just to win farmers' gratitude is not remotely the same as having a legitimate national energy policy.'

Submission + - The Wrong Way to Weaponize Social Media (foreignaffairs.com)

BorgiaPope writes: NYU's Clay Shirky, in the new issue of Foreign Affairs, calls the U.S. government's approach to social media "dangerous" and "almost certainly wrong," as in its favoring Haystack over Freegate. The Political Power of Social Media claims that the freedom of online assembly — via texting, photo sharing, Facebook, Twitter, humble email — is more important even than access to information via an uncensored Internet. Countering Malcolm Gladwell in the New Yorker, Shirky looks at recent uprisings in the Philippines, Moldova, and Spain to make his point that, instead of emphasizing anti-censorship tools, the U.S. should be fighting Egypt's recent mandatory licensing of group-oriented text-messaging services.

Submission + - British Pizza Chain To Install Cones of Silence (itworld.com) 2

itwbennett writes: British pizza chain Pizza Express is installing iPod docks and soundproof domes in booths of their new iPizzeria stores. 'The idea is that you can plug in your iPod and play whatever music you like without disturbing other diners,' says blogger Peter Smith. 'But I'm sure it'd work for talking about government secrets and other spy stuff, too.'

Prosecutors Request Closed Courtroom For Goldman HFT Programmer's Trial 250

dave562 writes "Goldman Sachs' lawyers have asked the Federal judge to seal the court room during the trial of Sergey Aleynikov. Aleynikov was one of the programmers who developed Goldman's High Frequency Trading (HFT) programs. What does this say about the state of the financial industry? Given the problems HFT seems to have caused over the last few years, shouldn't more light be shined into the dark corners of how it works?"

Comment Logarithmic Chart Axis: Confusing! (Score 1) 224

Logarithmic chart axis scales are used to make logarithmic functions easier to draw by hand-- when you show a logarithmic function against a logarithmic axis scale, they present as a straight line instead of a curved line. Zip, the straight edge does all the work to make the result very nice, thank you Mr. Straight Edge and Mr. Light Table. Logarithmic axis scales are also used in the case of a computer-drawn chart of a function formerly/typically shown with logarithmic axis scales when drawn by hand. This disc performance chart is neither! It's simply confusing, because the slower drives' functions appear to be bigger than they normally would in comparison to a linear scale. Does any other site or graph show disc performance data on a logarithmic chart?

An Animal That Lives Without Oxygen 166

Julie188 writes "Scientists have found the first multicellular animals that apparently live entirely without oxygen. The creatures reside deep in one of the harshest environments on earth: the Mediterranean Ocean's L'Atalante basin, which contains salt brine so dense that it doesn't mix with the oxygen-containing waters above."
