An anonymous reader quotes a report from TorrentFreak: With tens of millions of regular monthly visitors, South Korean piracy site Noonoo TV made powerful enemies. The stand-off reached the boiling point in March when broadcasters formed a new anti-piracy coalition and warned of punishing legal action. Noonoo TV responded by throwing in the towel but after clone site 'Noonoo TV Season 2' appeared online, the government says it will develop an AI anti-piracy system that will stop any 'Season 3' variants in their tracks.

Alongside a promise to work closely with the Ministry of Culture, Sports and Tourism, the Korea Communications Commission, and the National Security Agency to protect 'K' content from unlawful distribution, the Ministry of Science says the time is right to enhance manual work carried out by humans with automated systems better suited to the job. "Since the detection and response to illegal sites is currently centered on manual work based on human resources, to overcome this limitation, we plan to develop technology that can automatically detect and verify new versions and substitute sites," the Ministry said. "Online video service (OTT) content is a precious asset created with the blood and sweat of many people. It's a growth engine that will be responsible for the future of our country, so it is very important for mature citizens to refrain from using these illegal sites."

Accenture fanned concerns about dwindling IT spending on Thursday with a quarterly revenue forecast that was below Wall Street estimates, sending its shares down more than 5%. From a report: CEO Julie Sweet said clients were "holding back on small deals" in the face of an uncertain economic outlook, mirroring remarks from Cognizant Technology Solutions last month. Accenture forecast current-quarter revenue in the range of $15.75 billion to $16.35 billion. Analysts on average expect revenue of $16.35 billion, according to Refinitiv data.

The company blamed the weakness on its business catering to the tech, media and communications industries, which have sharply dialed back spending in recent months to cope with slowing growth. Revenue for that group fell 8% in the third quarter. North America - Accenture's biggest market - also performed poorly in the March to May period, with revenue growth slowing there to a near three-year low of about 2%.

Microsoft is increasing its Xbox Series X prices in most countries in August apart from the US, Japan, Chile, Brazil, and Colombia. From a report: The Xbox maker is also increasing the monthly prices of its Xbox Game Pass and Xbox Game Pass Ultimate subscriptions for the first time next month, which will see the base Game Pass subscription for console move up to $10.99 a month from $9.99. "We've held on our prices for consoles for many years and have adjusted the prices to reflect the competitive conditions in each market," says Kari Perez, head of communications for Xbox, in a statement to The Verge. Xbox Series X console pricing will largely match the price hike Sony announced for the PS5 last year, with the Xbox Series X moving to $612 in the UK, $604 across most European markets, CAD $649.99 in Canada, and AUD $799.99 in Australia starting August 1st. The Xbox Series S pricing will not be adjusted in any markets, remaining at $299.99.

According to AST SpaceMobile, the company managed to successfully transmit a 4G LTE signal from space that was picked up by "everyday, off-the-shelf smartphones." Next, AST will try and transmit a 5G connection via its BlueWalker 3 (BW3) satellite. The Verge reports: Testing was conducted in Hawaii on AT&T's spectrum using Nokia RAN technology, and the signal, which was beamed from AST's satellite in low Earth orbit, reached speeds of up to 10.3Mbps. That's fast enough for some video streaming, general internet use, and more ordinary cell phone usage. AST's testing followed a recent April test by the same company, where it was able to route an audio call between a Samsung Galaxy S22 in Texas to an iPhone in Japan via satellite.

The BW3 is a massive commercial communication array at 693 square feet -- about the size of a two- or three-car garage -- and the largest ever deployed in low Earth orbit, says AST's release. It operates using the same 3GPP standard found in ground-based cell networks. The achievement is "an important step toward AST SpaceMobile's goal of bringing broadband services to parts of the world where cellular coverage is either unreliable or simply does not exist today," according to AST's chairman and CEO, Abel Avellan, who said this would allow users to text and call, browse the internet, download files, and even stream video using a signal beamed from space.

An anonymous reader quotes a report from Ars Technica: Internet service providers in both the US and Europe are clamoring for new payments from Big Tech firms. European broadband providers are much closer to realizing the long-held goal of payments from tech companies, as the European Union government is holding an official consultation on the proposal. As the EU process unfolds, the telco lobby group USTelecom is hoping to push the US down a similar but not quite identical path. In a blog post on Friday, USTelecom CEO Jonathan Spalter argued that the biggest technology companies should contribute toward a fund that subsidizes the building of broadband networks. Spalter wrote that Amazon and similar Internet companies should fill what he called a "conspicuously empty seat at the collective table of global high-speed connectivity."

Given that "six companies account for half of all Internet traffic worldwide... Does it still make sense that the government and broadband providers alone fund this critical infrastructure? Is there no shared obligation from the primary financial beneficiaries of these networks -- the world's most powerful Internet companies?" Spalter wrote. "We need a modern reset that more equitably shares these financial obligations among those who benefit the most from these connections," he argued. USTelecom members include AT&T, Verizon, Lumen (formerly CenturyLink), Windstream, and other telcos. It's one of the biggest trade groups that lobbies for US-based Internet service providers.

[...] USTelecom pointed to the Biden administration's comments in its pitch to make Big Tech firms pay into a central fund like the existing Universal Service Fund (USF) managed by the Federal Communications Commission. "We concur with the US government's position that rather than the payments to broadband providers proposed in the EU, such 'publicly accountable funding mechanisms can better ensure that resources are devoted to key policy objectives, such as improving access and strengthening network security, while avoiding discriminatory measures that distort competition,'" Spalter wrote. The Biden administration's comments didn't call for tech companies to pay into a government-run fund, though. The document noted that the US "approach to financing improvements to broadband infrastructure involves private investments, a national Universal Service Fund, and significant public funding made from general appropriations," but didn't argue for any changes to who pays into the fund.

An anonymous reader quotes a report from MIT Technology Review: If we're going to prevent the gravest dangers of global warming, experts agree, removing significant amounts of carbon dioxide from the atmosphere is essential. That's why, over the past few years, projects focused on growing seaweed to suck CO2 from the air and lock it in the sea have attracted attention -- and significant amounts of funding -- from the US government and private companies including Amazon. The problem: farming enough seaweed to meet climate-change goals may not be feasible after all.

A new study, published today in Nature Communications Earth & Environment, estimates that around a million square kilometers of ocean would need to be farmed in order to remove a billion tons of carbon dioxide from the atmosphere over the course of a year. It's not easy to come by that amount of space in places where seaweed grows easily, given all the competing uses along the coastlines, like shipping and fishing. To put that into context, between 2.5 and 13 billion tons of atmospheric carbon dioxide would need to be captured each year, in addition to dramatic reductions in greenhouse-gas emissions, to meet climate goals, according to the study's authors.

A variety of scientific models suggest we should be removing anything from 1.3 billion tons of carbon dioxide each year to 29 billion tons by 2050 in order to prevent global warming levels from rising past 1. 5C. An 2017 report from the UN estimated that we'd need to remove 10 billion tons annually to stop the planet from warming past 2C by the same date. "The industry is getting ahead of the science," says Isabella Arzeno-Soltero, a postdoctoral scholar at Stanford University, who worked on the project. "Our immediate goal was to see if, given optimal conditions, we can actually achieve the scales of carbon harvests that people are talking about. And the answer is no, not really." [...] Their findings suggest that cultivating enough seaweed to reach these targets is beyond the industry's current capacity, although meeting climate goals will require much more than reliance solely on seaweed.

Indonesia and Elon Musk's rocket company SpaceX on Monday launched the country's largest telecommunication satellite from the United States, in a $540 million project intended to link up remote corners of the archipelago to the internet. From a report: Roughly two-thirds of Indonesia's 280 million population already use the internet, but connectivity is limited in far-flung, underdeveloped eastern islands of the Southeast Asian country. "Satellite technology will accelerate internet access to villages in areas that cannot be reached by fiber optics in the next 10 years," Mahfud MD, senior Indonesian minister, said in a statement ahead of the launch. The 4.5-tonne Satellite of the Republic of Indonesia (SATRIA-1) was built by Thales Alenia Space and deployed into orbit from Florida by SpaceX's Falcon 9 rocket, which then returned to an offshore site in a precision landing.

Long-time Slashdot reader theodp writes: Y Combinator founder Paul Graham last week took to Twitter to lament those who use AI or other excuses for not learning to code. "A generation ago some people were saying there was no point in learning to program because all the programming jobs would be outsourced to India," Graham wrote. "Now they're saying you don't need to because AI will do it all. If you don't want to learn to program, you can always find a reason."

BloomTech Coding Bootcamp CEO Austen Allred this week doubled-down on Graham's tweet, offering his own history of excuses people have made for not learning to code... Allred's tweet reads:

"Don't learn to code. Soon GUIs will do it all for you." — 1985

"Don't learn to code. Soon that will all be done offshore for pennies." — 2003

"Don't learn to code. Soon nocode tools will do it all for you." — 2015

"Don't learn to code. Soon AI will do it all for you." — 2023

Among the many retweeting Allred's cautionary message was Code.org, the tech-backed nonprofit that aims to make computer science a high school graduation requirement by 2030, whose CEO also replied to Graham with a reassuring tweet suggesting people's days of being able to avoid learning to code will soon be over. "Now that 27 states require that every school must teach computer science, and 7 states require a CS course to graduate high school," explained Code.org CEO Hadi Partovi, "the argument is basically behind us. Computer science won."
On a related note, this month in Communications of the ACM, a CS professor shared their own contrary opinion about the possibility of a professional programmer using AI assistants to do a better job.

"It doesn't work." I would love to have an assistant who keeps me in check, alerting me to pitfalls and correcting me when I err. A effective pair-programmer. But that is not what I get. Instead, I have the equivalent of a cocky graduate student, smart and widely read, also polite and quick to apologize, but thoroughly, invariably, sloppy and unreliable. I have little use for such supposed help...

Fascinating as they are, AI assistants are not works of logic; they are works of words. Large language models: smooth talkers (like the ones who got all the dates in high school). They have become incredibly good at producing text that looks right. For many applications that is enough. Not for programming.

According to Dish, the company says it now covers 70 percent of the U.S. population and has "also satisfied all other June 14, 2023 FCC commitments." The Verge reports: In meeting this FCC milestone, Dish says it has deployed over 15,000 5G cell sites and would like to remind us that it's still the first wireless provider in the country to launch voice calling over 5G, known as VoNR -- Voice over New Radio. This is all well and good, but Dish's wireless service still doesn't look quite the same as AT&T's or Verizon's. The network itself is very much still in beta testing under its Project Genesis program, which requires you to purchase a new phone specially equipped to use new network features like three-carrier aggregation. The network is available to Boost customers in supported markets, but they need to use a phone that supports band 70 to access Dish's 5G -- and those are still uncommon.

Federal Communications Commission Chairwoman Jessica Rosenworcel wants the FCC to open a formal inquiry into how data caps harm Internet users and why broadband providers still impose the caps. The inquiry could eventually lead to the FCC regulating how Internet service providers such as Comcast impose limits on data usage. From a report: Rosenworcel yesterday announced that she asked fellow commissioners to support a Notice of Inquiry on the topic. Among other things, the Notice would seek comment from the public "to better understand why the use of data caps continues to persist despite increased broadband needs of consumers and providers' demonstrated technical ability to offer unlimited data plans."

The inquiry would also seek comment on "trends in consumer data usage... on the impact of data caps on consumers, consumers' experience with data caps, how consumers are informed about data caps on service offerings, and how data caps impact competition." Finally, Rosenworcel wants to seek comment about the FCC's "legal authority to take actions regarding data caps." "In particular, the agency would like to better understand the current state of data caps, their impact on consumers, and whether the Commission should consider taking action to ensure that data caps do not cause harm to competition or consumers' ability to access broadband Internet services," the press release said.

The massive federal effort to expand internet access to every home in the U.S. took a major step forward on Friday with the announcement of $930 million in grants to shore up connections in remote parts of Alaska, rural Texas and dozens of other places where significant gaps in connectivity persist. From a report: The so-called middle mile grants, announced by the Department of Commerce, are meant to create large-scale networks that will enable retail broadband providers to link subscribers to the internet. Department officials likened the role of the middle mile -- the midsection of the infrastructure necessary to enable internet access, composed of high-capacity fiber lines carrying huge amounts of data at very high speeds -- to how the interstate highway system forged connections between communities. "These networks are the workhorses carrying large amounts of data over very long distances," said Mitch Landrieu, the White House's infrastructure coordinator, in a media Zoom call. "They're the ones that are bridging the gap between the larger networks and the last mile connections, from tribal lands to underserved rural and remote areas to essential institutions like hospitals, schools, libraries and major businesses."

Sens. Josh Hawley and Richard Blumenthal want to clarify that the internet's bedrock liability law does not apply to generative AI, per a new bill introduced Wednesday. From a report: Legal experts and lawmakers have questioned whether AI-created works would qualify for legal immunity under Section 230 of the Communications Decency Act, the law that largely shields platforms from lawsuits over third-party content. It's a newly urgent issue thanks to the explosive of generative AI. The new bipartisan bill bolsters the argument that Section 230 doesn't cover AI-generated work. It also gives lawmakers an opening to go after Section 230 after vowing to amend it, without much success, for years.

Section 230 is often credited as the law that allowed the internet to flourish and for social media to take off, as well as websites hosting travel listings and restaurant reviews. To its detractors, it goes too far and is not fit for today's web, allowing social media companies to leave too much harmful content up online. Hawley and Blumenthal's "No Section 230 Immunity for AI Act" would amend Section 230 "by adding a clause that strips immunity from AI companies in civil claims or criminal prosecutions involving the use or provision of generative AI," per a description of the bill from Hawley's office.

mschaffer shares a report: Comcast and other ISPs have annoyed customers for many years by advertising low prices and then charging much bigger monthly bills by tacking on a variety of fees. While some of these fees are related to government-issued requirements and others are not, poorly trained customer service reps have been known to falsely tell customers that fees created by Comcast are mandated by the government. The FCC rules will force ISPs to accurately describe fees in labels given to customers, but Comcast said it wants the FCC to rescind a requirement related to "fees that ISPs may, but are not obligated to, pass through to customers." These include state Universal Service fees and other local fees. As Comcast makes clear, it isn't required to pass these costs on to customers in the form of separate fees. Comcast could stop charging the fees and raise its advertised prices by the corresponding amount to more accurately convey its actual prices to customers. Instead, Comcast wants the FCC to change the rule so that it can continue charging the fees without itemizing them..

I suppose it's just easier to grab people's money than it is to make up names for the fees, Mschaffer adds.

The hackers responsible for the MOVEit cyberattack downloaded confidential information from UK communications regulator Ofcom about companies it regulates, as well as its own employees -- adding to a string of victims which includes IAG SA's British Airways and the British Broadcasting Corporation. From a report: "A limited amount of information about certain companies we regulate -- some of it confidential -- along with personal data of 412 Ofcom employees, was downloaded during the attack," an Ofcom spokesman said by email. "We took immediate action to prevent further use of the MOVEit service and to implement the recommended security measures. We also swiftly alerted all affected Ofcom-regulated companies, and we continue to offer support and assistance to our colleagues."

"Kairan Quazi will probably need someone to drive him to work at SpaceX," writes the Los Angeles Times — because "He's only 14." The teen is scheduled to graduate this month from the Santa Clara University School of Engineering before starting a job as a software engineer at the satellite communications and spacecraft manufacturer... The soft-spoken teen said working with Starlink — the satellite internet team at SpaceX — will allow him to be part of something bigger than himself. That is no small feat for someone who has accomplished so much at such a young age...

The youngster jumped from third grade to a community college, with a workload that he felt made sense. "I felt like I was learning at the level that I was meant to learn," said Kairan, who later transferred to Santa Clara University... Kairan's family told BrainGain Magazine that when he was 9, IQ tests showed that his intelligence was in the 99.9th percentile of the general population. Asked if he's a genius, he recalled his parents telling him, "Genius is an action â it requires solving big problems that have a human impact." Once accepted to the engineering school at Santa Clara University as a transfer student, Kairan felt that he had found his freedom to pursue a career path that allowed him to solve those big problems.

While in college, Kairan and his mother made a list of places where he could apply for an internship. Only one company responded. Lama Nachman, director of the Intelligent Systems Research Lab at Intel, took a meeting with 10-year-old Kairan, who expected it to be brief and thought she would give him the customary "try again in a few years," he said. She accepted him. "In a sea of so many 'no's' by Silicon Valley's most vaunted companies, that ONE leader saying yes ... one door opening ... changed everything," Kairan wrote on his LinkedIn page...

Asked what he plans to wear on his first day, Kairan joked in an email that he plans "to show up in head to toe SpaceX merch. I'll be a walking commercial! Joking aside, I'll probably wear jeans and a t-shirt so I can be taken seriously as an engineer."

New research suggests that Arctic summer sea ice could melt almost completely by the 2030s, a decade earlier than previously projected, even with significant greenhouse gas emissions reductions. Smithsonian Magazine reports: "We are very quickly about to lose the Arctic summer sea-ice cover, basically independent of what we are doing," Dirk Notz, a climate scientist at the University of Hamburg in Germany tells the New York Times' Raymond Zhong. "We've been waiting too long now to do something about climate change to still protect the remaining ice." An ice-free summer, also called a "blue ocean event," will happen when the sea ice drops below one million square kilometers (386,102 square miles), writes Jonathan Bamber, a professor of physical geography at the University of Bristol, in the Conversation. This equates to just 15 percent of the Arctic's seasonal minimum ice cover of the late 1970s, per the Times.

Previous assessments using models have estimated an ice-free summer under high and intermediate emissions scenarios by 2050. But researchers noticed differences between what climate models predicted about what would happen to sea ice and what they've actually seen through observations, according to Bob Weber of the Canadian Press. "The models, on average, underestimate sea ice decline compared with observations," says Nathan Gillett, an environment and climate change Canada scientist, to Weber.

Now, in a new study published in Nature Communications, Notz, Gillett and their colleagues tweaked these models to more closely fit satellite data collected over the past 40 years. Using these modified models, the researchers projected ice changes under different possible levels of greenhouse gas emissions. Their paper suggests that regardless of emissions scenario, "we may experience an unprecedented ice-free Arctic climate in the next decade or two." Under a high emissions scenario, the Arctic could see a sustained loss of sea ice from August until as late as October before the 2080s, lead author Seung-Ki Min, a climate scientist at Pohang University of Science and Technology in South Korea, tells CNN's Rachel Ramirez.

schwit1 shares a report from Electrek: Tesla is planning to produce 375,000 Cybertrucks per year and have release candidates by late August, according to communications they sent to suppliers. Tesla's latest official comment on the timeline is a planned delivery event "around the end of Q3," which would mean around the end of September 2023.

Recently, CEO Elon Musk also gave a Tesla Cybertruck production volume estimate at Tesla's annual shareholders meeting. In his comment, he first said about 250,000 units per year, but the CEO also added that he believes it could be between 250,000 and 500,000 units a year. Now, Electrek gets more details through communications that Tesla sent to suppliers for the Cybertruck program, which it calls "Project Everest," internally and with suppliers.

Tesla has asked suppliers to plan to meet a base production volume of 375,000 Cybertrucks per year. For a base volume, it seems to be a bit more aggressive than what Musk communicated publicly at Tesla's annual shareholder's meeting, but Tesla has been frequently adjusting to target. Earlier this year, it was about 100,000 units lower. Also, the number is planned for the production lines running at 85% efficiency.

Artificial photosynthesis, inspired by the natural process that enables plants to convert sunlight, water, and carbon dioxide into oxygen and energy, could be crucial for space exploration and colonization. By using semiconductor materials and metallic catalysts, these devices could efficiently produce oxygen and recycle carbon dioxide, reducing reliance on heavy and unreliable systems currently used on the International Space Station. ScienceAlert reports: As my colleagues and I have investigated in a new paper, published in Nature Communications, recent advances in making artificial photosynthesis may well be key to surviving and thriving away from Earth. [...] We produced a theoretical framework to analyze and predict the performance of such integrated "artificial photosynthesis" devices for applications on Moon and Mars. Instead of chlorophyll, which is responsible for light absorption in plants and algae, these devices use semiconductor materials which can be coated directly with simple metallic catalysts supporting the desired chemical reaction. Our analysis shows that these devices would indeed be viable to complement existing life support technologies, such as the oxygen generator assembly employed on the ISS. This is particularly the case when combined with devices which concentrate solar energy in order to power the reactions (essentially large mirrors which focus the incoming sunlight).

There are other approaches too. For example, we can produce oxygen directly from lunar soil (regolith). But this requires high temperatures to work. Artificial photosynthesis devices, on the other hand, could operate at room temperature at pressures found on Mars and the Moon. That means they could be used directly in habitats and using water as the main resource. This is particularly interesting given the stipulated presence of ice water in the lunar Shackleton crater, which is an anticipated landing site in future lunar missions.

On Mars, the atmosphere composes of nearly 96% carbon dioxide - seemingly ideal for an artificial photosynthesis device. But the light intensity on the red planet is weaker than on Earth due to the larger distance from the Sun. So would this pose a problem? We actually calculated the sunlight intensity available on Mars. We showed that we can indeed use these devices there, although solar mirrors become even more important. [...] The returns would be huge. For example, we could actually create artificial atmospheres in space and produce chemicals we require on long-term missions, such as fertilizers, polymers, or pharmaceuticals. Additionally, the insights we gain from designing and fabricating these devices could help us meet the green energy challenge on Earth.

An anonymous reader quotes a report from The Register: The world got a first glimpse into the US government's far-reaching surveillance of American citizens' communications -- namely, their Verizon telephone calls -- 10 years ago this week when Edward Snowden's initial leaks hit the press. [...] In the decade since then, "reformers have made real progress advancing the bipartisan notion that Americans' liberty and security are not mutually exclusive," [US Senator Ron Wyden (D-OR)] said. "That has delivered tangible results: in 2015 Congress ended bulk collection of Americans' phone records by passing the USA Freedom Act." This bill sought to end the daily snooping into American's phone calls by forcing telcos to collect the records and make the Feds apply for the information.

That same month, a federal appeals court unanimously ruled that the NSA's phone-records surveillance program was unlawful. The American Civil Liberties Union (ACLU) and the New York Civil Liberties Union sued to end the secret phone spying program, which had been approved by the Foreign Intelligence Surveillance Court, just days after Snowden disclosed its existence. "Once it was pushed out into open court, and the court was able to hear from two sides and not just one, the court held that the program was illegal," Ben Wizner, director of the ACLU Speech, Privacy and Technology project, told The Register. The Freedom Act also required the federal government to declassify and release "significant" opinions of the Foreign Intelligence Surveillance Court (FISC), and authorized the appointment of independent amici -- friends of the court intended to provide an outside perspective. The FISC was established in 1978 under the FISA -- the legislative instrument that allows warrantless snooping. And prior to the Freedom Act, this top-secret court only heard the government's perspective on things, like why the FBI and NSA should be allowed to scoop up private communications.

"To its credit, the government has engaged in reforms, and there's more transparency now that, on the one hand, has helped build back some trust that was lost, but also has made it easier to shine a light on surveillance misconduct that has happened since then," Jake Laperruque, deputy director of the Center for Democracy and Technology's Security and Surveillance Project, told The Register. Wyden also pointed to the sunsetting of the "deeply flawed surveillance law," Section 215 of the Patriot Act, as another win for privacy and civil liberties. That law expired in March 2020 after Congress did not reauthorize it. "For years, the government relied on Section 215 of the USA Patriot Act to conduct a dragnet surveillance program that collected billions of phone records (Call Detail Records or CDR) documenting who a person called and for how long they called them -- more than enough information for analysts to infer very personal details about a person, including who they have relationships with, and the private nature of those relationships," Electronic Frontier Foundation's Matthew Guariglia, Cindy Cohn and Andrew Crocker said. James Clapper, the former US Director of National Intelligence, "stated publicly that the Snowden disclosures accelerated by seven years the adoption of commercial encryption," Wizner said. "At the individual level, and at the corporate level, we are more secure."

"And at the corporate level, what the Snowden revelations taught big tech was that even as the government was knocking on the front door, with legal orders to turn over customer data, it was breaking in the backdoor," Wizner added. "Government was hacking those companies, finding the few points in their global networks where data passed unencrypted, and siphoning it off." "If you ask the government -- if you caught them in a room, and they were talking off the record -- they would say the biggest impact for us from the Snowden disclosures is that it made big tech companies less cooperative," he continued. "I regard that as a feature, not a bug."

The real issue that the Snowden leaks revealed is that America's "ordinary system of checks and balances doesn't work very well for secret national security programs," Wizner said. "Ten years have gone by," since the first Snowden disclosures, "and we don't know what other kinds of rights-violating activities have been taking place in secret, and I don't trust our traditional oversight systems, courts and the Congress, to ferret those out," Wizner said. "When you're dealing with secret programs in a democracy, it almost always requires insiders who are willing to risk their livelihoods and their freedom to bring the information to the public."

Researchers at the California Institute of Technology (Caltech) have successfully demonstrated the capability of steering power in a microwave beam from a satellite to targets in space, as well as transmitting some of that power to a detector on Earth. Science Magazine reports: The Caltech mission, funded by the Donald Bren Foundation and Northrop Grumman Corporation, aimed to go a step further with lightweight, inexpensive, and flexible components. The microwave transmitter was an array of 32 flat antennas packed onto a surface slightly larger than a dinner plate. By varying the timing of signals sent to the different antennas, the researchers could steer the array's beam. They pointed it at a pair of microwave receivers about a forearm's distance away and switched the beam from one receiver to the other at will, lighting up an LED on each.

The transmitted power was small, just 200 milliwatts, less than that of a cellphone camera light. But the team was still able to steer the beam toward Earth and detect it with a receiver at Caltech. "It was a proof of concept," says Caltech electrical engineer Ali Hajimiri. "It indicates what an overall system can do."

The Caltech spacecraft still has two more planned experiments. One is now testing 32 different varieties of solar cell to see which best survives the rigors of space. The second is a folded piece of ultralight composite material that will unfurl into a sail-like structure 2 meters across. Although the sail will not hold any solar cells, it is meant to test the kind of thin, flexible, and large deployments required for a future power station.
