A government panel in Japan drew up a set of regulations aimed at opening up the smartphone app stores of U.S. technology giants Apple and Google to competition. From a report: The two companies dominating the smartphone operating system market will be obliged to allow their users to download apps by using services other than their own app stores. The government hopes that the move will spur competition and lead to app price drops. The smartphone OS market is occupied almost entirely by Apple's iOS and Google's Android. The companies control how apps are installed and paid for on their iPhones and Android devices.

The government will create a list of what OS providers must not do in order to stop them favoring their own services and payment platforms. The regulations were drawn up at the government's headquarters for digital market competition, headed by Chief Cabinet Secretary Hirokazu Matsuno. The government aims to submit relevant legislation to the next year's ordinary session of parliament. Apple makes it impossible for iPhone users to download apps without using its App Store. Of Android users, 97% download apps through the Google Play store, although Google does not require them to do so.

An anonymous reader shares a report: GPS is now a mainstay of daily life, helping us with navigation, tracking, mapping, and timing across a broad spectrum of applications. But it does have a few shortcomings, most notably not being able to pass through buildings, rocks, or water. That's why Japanese researchers have developed an alternative wireless navigation system that relies on cosmic rays, or muons, instead of radio waves, according to a new paper published in the journal iScience. The team has conducted its first successful test, and the system could one day be used by search and rescue teams, for example, to guide robots underwater or to help autonomous vehicles navigate underground.

"Cosmic-ray muons fall equally across the Earth and always travel at the same speed regardless of what matter they traverse, penetrating even kilometers of rock," said co-author Hiroyuki Tanaka of Muographix at the University of Tokyo in Japan. "Now, by using muons, we have developed a new kind of GPS, which we have called the muometric positioning system (muPS), which works underground, indoors and underwater."

Apple, the company, wants rights to the image of apples, the fruit, in Switzerland -- one of dozens of countries where it's flexing its legal muscles. From a report The Fruit Union Suisse is 111 years old. For most of its history, it has had as its symbol a red apple with a white cross -- the Swiss national flag superimposed on one of its most common fruits. But the group, the oldest and largest fruit farmer's organization in Switzerland, worries it might have to change its logo, because Apple, the tech giant, is trying to gain intellectual property rights over depictions of apples, the fruit. "We have a hard time understanding this, because it's not like they're trying to protect their bitten apple," Fruit Union Suisse director Jimmy Mariethoz says, referring to the company's iconic logo. "Their objective here is really to own the rights to an actual apple, which, for us, is something that is really almost universal ... that should be free for everyone to use."

While the case has left Swiss fruit growers puzzled, it's part of a global trend. According to the World Intellectual Property Organization's records, Apple has made similar requests to dozens of IP authorities around the world, with varying degrees of success. Authorities in Japan, Turkey, Israel, and Armenia have acquiesced. Apple's quest to own the IP rights of something as generic as a fruit speaks to the dynamics of a flourishing global IP rights industry, which encourages companies to compete obsessively over trademarks they don't really need. Apple's attempts to secure the trademark in Switzerland go as far back as 2017, when the Cupertino, California-based giant submitted an application to the Swiss Institute of Intellectual Property (IPI) requesting the IP rights for a realistic, black-and-white depiction of an apple variety known as the Granny Smith -- the generic green apple.

The request covered an extensive list of potential uses -- mostly on electronic, digital, and audiovisual consumer goods and hardware. Following a protracted back-and-forth between both parties, the IPI partially granted Apple's request last fall, saying that Apple could have rights relating to only some of the goods it wanted, citing a legal principle that considers generic images of common goods -- like apples -- to be in the public domain. In the spring, Apple launched an appeal. The case now moving through the courts deals only with the goods for which the IPI refused the trademark, which an IPI official said could not be disclosed without consent from Apple, because the proceedings are still pending, but which include common uses such as audiovisual footage "meant for television and other transmission."

Researchers have discovered high concentrations of phosphorus in ice crystals emitted from Saturn's moon Enceladus, enhancing its potential to support life. The findings, based on data from NASA's Cassini spacecraft, suggest that Enceladus may possess the necessary elements for life. Reuters reports: The discovery was based on data collected by NASA's Cassini spacecraft, the first to orbit Saturn, during its 13-year landmark exploration of the gaseous giant planet, its rings and its moons from 2004 to 2017. The same team previously confirmed that Enceladus' ice grains contain a rich assortment of minerals and complex organic compounds, including the ingredients for amino acids, associated with life as scientists know it. But phosphorus, the least abundant of six chemical elements considered necessary to all living things -- the others are carbon, oxygen, hydrogen, nitrogen and sulphur -- was still missing from the equation until now.

"It's the first time this essential element has been discovered in an ocean beyond Earth," the study's lead author, Frank Postberg, a planetary scientist at the Free University in Berlin, said in a JPL press release. [...] One notable aspect of the latest Enceladus discovery was geochemical modeling by the study's co-authors in Europe and Japan showing that phosphorus exists in concentrations at least 100 times that of Earth's oceans, bound water-soluble forms of phosphate compounds. "This key ingredient could be abundant enough to potentially support life in Enceladus' ocean," said co-investigator Christopher Glein, a planetary scientist at Southwest Research Institute in San Antonio, Texas. "This is a stunning discovery for astrobiology." "Whether life could have originated in Enceladus' ocean remains an open question," Glein said.

Experts say the subsea cable market is in danger of dividing into eastern and western blocs amid fears of espionage and geopolitical tensions. From a report: Nearly 1.4mn kilometres of metal-encased fibre criss-crosses the world's oceans, speeding internet traffic seamlessly around the globe. The supply and installation of these cables has been dominated by companies from France, the US and Japan. The Chinese government started successfully penetrating the global market, but consecutive US administrations have since managed to freeze China out of large swathes of it. This was ostensibly because of concerns of espionage and worries about what Beijing might do to disrupt strategic assets operated by Chinese companies in the event of a conflict. Despite being routinely blocked from international subsea cable projects involving US investment, Chinese companies have adapted by building international cables for China and many of its allied nations. This has raised fears of a dangerous division in who owns and manages the infrastructure underpinning the global web.

In 2018, Amazon, Meta and China Mobile agreed to work together on a cable connecting California to Singapore, Malaysia and Hong Kong. But a spate of manoeuvres in Washington to block Chinese participation in US cables led to China Mobile pulling out of the consortium. Meta and Amazon filed a new application for the system in 2021, this time with no Chinese investment, no connection to Hong Kong, and a new name: Cap-1. Then, last year, the application for Cap-1 was withdrawn altogether, even though most of the 12,000km cable had already been built. China's original involvement remained a security concern for the US government, according to two people briefed on the discussions. "There are hundreds of millions of dollars sunk in the Pacific," said a person involved in the aborted project. Over the last five years, as tensions between the two countries have mounted and fears have grown in Washington about the risks of espionage, the US government has sought to pull apart an interwoven network of internet cables that had developed through international collaboration over decades.

OpenAI CEO Sam Altman warned during a visit to the United Arab Emirates that AI poses an "existential risk" to humanity and suggested the establishment of an international agency, similar to the International Atomic Energy Agency (IAEA), to oversee AI. The Associated Press reports: "We face serious risk. We face existential risk," said Altman, 38. "The challenge that the world has is how we're going to manage those risks and make sure we still get to enjoy those tremendous benefits. No one wants to destroy the world." Altman made a point to reference the IAEA, the United Nations nuclear watchdog, as an example of how the world came together to oversee nuclear power. That agency was created in the years after the U.S. dropping atom bombs on Japan at the end of World War II.

"Let's make sure we come together as a globe -- and I hope this place can play a real role in this," Altman said. "We talk about the IAEA as a model where the world has said 'OK, very dangerous technology, let's all put some guard rails.' And I think we can do both. "I think in this case, it's a nuanced message 'cause it's saying it's not that dangerous today but it can get dangerous fast. But we can thread that needle."

Japan's government on Tuesday adopted a revision to the country's plans to use more hydrogen as fuel as part of the effort to reduce carbon emissions. From a report: The plan sets an ambitious target to increase the annual supply by six times from the current level to 12 million tons by 2040. It also pledges 15 trillion yen ($107 billion) in funding from both private and public sources to build up hydrogen-related supply chains over the next 15 years.

Japan's decarbonization strategy centers on using so-called clean coal, hydrogen and nuclear energy to bridge its transition to renewable energy. Russia's war on Ukraine has deepened concerns over energy security and complicated that effort, but other advanced Western nations are pushing for faster adoption of renewable energy, such as solar, wind and geothermal. So far, Japan is relying on hydrogen mainly produced using fossil fuels.

An anonymous reader quotes a report from The Guardian: Japan has extended its natural disaster preparations to vending machines, which will offer free food and drink in the event of a major earthquake or typhoon. Two machines have been installed in the western coastal city of Ako, located in a region that seismologists say is vulnerable to a powerful earthquake that is expected to hit the country's central and south-west pacific coast in the next few decades. The machines, which contain about 300 bottles and cans of soft drinks and 150 emergency food items, including nutritional supplements, have been installed near buildings that have been designated as evacuation shelters.

They are designed to "unlock" and make their contents available free of charge in the event of a heavy rain warning, or an evacuation order after a quake of an upper five or higher on the Japanese seismic intensity scale of seven, according to the Mainichi Shimbun. Their contents must be paid for the rest of the time, the newspaper added. The manufacturer, Earth Corp, which has a factory in the city, says the machines are the first of their kind in Japan, one of the world's most seismically active countries, and where increasingly powerful typhoons have caused widespread flooding and landslides in recent years. "We would like to install [the machines] throughout the country," a company representative told the Mainichi. A city official said: "We expect that the stockpile will lead to the safety and security of our residents." Earlier this year, a vending machine with a radio that will automatically issue emergency broadcasts was set up in a park in Tokyo. "The radio will be activated by earthquakes registering 5 or higher on the Japanese intensity scale, and transmit evacuation and other vital information from a local community radio station," reports the Guardian.

The Japanese space agency (JAXA) and NASA plan to launch a satellite made of wood in 2024. The Independent reports: The high durability of wood in space was recently tested and confirmed at the International Space Station (ISS) by an international group of scientists led by those from Kyoto University. Their experiments showed wood samples tested at the ISS for durability underwent minimal deterioration and maintained good stability. Preliminary inspection, including strength tests and crystal structural analyses, of the wood samples was also done once they were brought back to Earth from the ISS by Japanese astronaut Koichi Wakata.

Despite extreme conditions in space, including temperature changes and exposure to intense cosmic rays and dangerous solar particles for 10 months, tests found no changes in the samples, such as cracking, warping, peeling or surface damage, according to a recent Kyoto University statement. The retrieved wood specimens were tested and showed no deformation after space exposure and also did not undergo any mass change before and after space exposure, scientists said.

The international research group has determined that the satellite LignoSat, slated to be jointly launched in 2024 by Nasa and Japan's space agency Jaxa, will likely use Magnolia wood -- "Hoonoki" in Japanese. Magnolia, researchers said, has relatively high workability, dimensional stability and overall strength, making its properties ideal for the mission. Wood also has some benefits compared to complex alloys used in space vehicles, as it is environmentally friendly, easier to produce and can be disposed off better at the end of a satellite's life. Such wooden satellites may also be designed to completely burn up on re-entry into the atmosphere and even if small fragments did survive, they may decompose easily.

An anonymous reader quotes a report from the Associated Press: An International Atomic Energy Agency team arrived in Tokyo on Monday for a final review before Japan begins releasing massive amounts of treated radioactive water into the sea from the wrecked Fukushima nuclear plant, a plan that has been strongly opposed by local fishing communities and neighboring countries. The team, which includes experts from 11 countries, will meet with officials from the government and the plant operator, Tokyo Electric Power Company Holdings, and visit the Fukushima Daiichi nuclear power plant during their five-day visit, the economy and industry ministry said.

Japan announced plans in April 2021 to gradually release the wastewater following further treatment and dilution to what it says are safe levels. The release is expected to begin within a few months after safety checks by Japanese nuclear regulators of the newly constructed water discharge facility and a final report by IAEA expected in late June. Japan sought IAEA's assistance in ensuring the release meets international safety standards and to gain the understanding of other countries.

Japanese officials say the water will be treated to legally releasable levels and further diluted with large amounts of seawater. It will be gradually released into the ocean over decades through an undersea tunnel, making it harmless to people and marine life, they say. Some scientists say the impact of long-term, low-dose exposure to radionuclides is unknown and the release should be delayed.

An anonymous reader shared this report from Engadget: Japan and JAXA, the country's space administration, have spent decades trying to make it possible to beam solar energy from space. In 2015, the nation made a breakthrough when JAXA scientists successfully beamed 1.8 kilowatts of power, enough energy to power an electric kettle, more than 50 meters to a wireless receiver. Now, Japan is poised to bring the technology one step closer to reality.

Nikkei reports a Japanese public-private partnership will attempt to beam solar energy from space as early as 2025. The project, led by Naoki Shinohara, a Kyoto University professor who has been working on space-based solar energy since 2009, will attempt to deploy a series of small satellites in orbit. Those will then try to beam the solar energy the arrays collect to ground-based receiving stations hundreds of miles away.
Orbital solar arrays "represent a potentially unlimited renewable energy supply," the article points out -- running 24 hours a day.

After three years of upgrades, the gravitational-wave detector known as LIGO, or Laser Interferometer Gravitational-Wave Observatory, has resumed searching for colliding black holes and other cosmic cataclysms. "The improvements should allow the facility to pick up signals from colliding black holes every two to three days, compared with once a week or so during its previous run in 2019-20," reports Nature. From the report: The Virgo detector near Pisa, Italy, which has undergone its own $9-million upgrade, was meant to join in, but technical issues are forcing its team to extend its shutdown and perform further maintenance. "Our expectation is we'll be able to restart by the end of summer or early autumn," says Virgo spokesperson Gianluca Gemme, a physicist at Italy's National Institute for Nuclear Physics in Genoa.

KAGRA, a gravitational-wave detector located under Mount Ikenoyama, Japan, is also restarting on 24 May. Its technology, although more advanced -- it was inaugurated in 2020 -- is being fine-tuned, and its sensitivity is still lower than LIGO's was in 2015. Principal investigator Takaaki Kajita, a Nobel Prize-winning physicist at the University of Tokyo, says that KAGRA will join LIGO's run for a month and then shut down again for another period of commissioning. At that point, the team will cool the interferometer's four main mirrors to 20 kelvin, Kajita says -- a feature that sets KAGRA apart from the other detectors that will serve as the model for next-generation observatories.

In upgrades carried out before the 2019-20 run, LIGO and Virgo tackled some of this noise with a technique called light squeezing. This approach deals with inherent noise caused by the fact that light is made of individual particles: when the beams arrive at the sensor, each individual photon can arrive slightly too early or too late, which means that the laser waves don't overlap and cancel out perfectly even in the absence of gravitational waves. "It's like dropping a bucket of BBs [lead pellets]: it's going to make a loud hiss, but they all hit randomly," physicist Lee McCuller explained while showing a prototype of the LIGO interferometers at the Massachusetts Institute of Technology (MIT) in Cambridge. Light squeezing injects an auxiliary laser beam into the interferometer that reduces that effect. "Its photons arrive more regularly, with less noise," said McCuller, who is now at the California Institute of Technology in Pasadena.

The two Koreas are elevating a space race aimed at modernizing how each country monitors the other's improving military firepower. From a report: As hopes for a diplomatic breakthrough have dimmed in recent years, North and South Korea have grown more antagonistic toward one another and upped their displays of military might. They have traded missile tests. Pyongyang has sent drones that flew over downtown Seoul. South Korea has sharpened security and defense ties with the U.S. and Japan. The rise in tensions has elevated the importance -- and need -- for spy-satellite technology that neither country now has. South Korea cleared a significant technological marker on Thursday, launching multiple commercial satellites aboard a homegrown rocket for the first time. North Korea's Kim Jong Un regime stands poised to soon fly its first military reconnaissance satellite.

Nuri, South Korea's three-stage liquid-fuel rocket, blasted off at 6:24 p.m. local time Thursday from the Naro Space Center in Goheung, a city on the country's southern coast. The 200-ton rocket launched into space and deployed eight satellites into orbit about 342 miles above Earth, about 13 minutes after liftoff. Seoul has the clear technological advantage, weapons analysts say, though Pyongyang has been quick to advance its sanctioned missile program to develop long-range rockets that can carry satellites. Both nations remain years away from having a full-fledged network of spy satellites. But attaining the technology would allow the countries to identify military targets to precisely launch strikes during potential conflict without relying on their allies' satellite technology for information. In North Korea's case, space-based satellite technology is essential for its nuclear strategy. Having eyes in the sky would serve as an additional asset to launching nuclear strikes with better accuracy, said Yang Uk, a military expert at the Asan Institute for Policy Studies, a think tank in Seoul. Should the technology progress enough, North Korea could potentially identify nuclear strike targets in the U.S., he added.

IBM has announced its goal to build a 100,000-qubit quantum computing machine within the next 10 years in collaboration with the University of Tokyo and the University of Chicago. MIT Technology Review reports: Late last year, IBM took the record for the largest quantum computing system with a processor that contained 433 quantum bits, or qubits, the fundamental building blocks of quantum information processing. Now, the company has set its sights on a much bigger target: a 100,000-qubit machine that it aims to build within 10 years. IBM made the announcement on May 22 at the G7 summit in Hiroshima, Japan. The company will partner with the University of Tokyo and the University of Chicago in a $100 million dollar initiative to push quantum computing into the realm of full-scale operation, where the technology could potentially tackle pressing problems that no standard supercomputer can solve.

Or at least it can't solve them alone. The idea is that the 100,000 qubits will work alongside the best "classical" supercomputers to achieve new breakthroughs in drug discovery, fertilizer production, battery performance, and a host of other applications. "I call this quantum-centric supercomputing," IBM's VP of quantum, Jay Gambetta, told MIT Technology Review in an in-person interview in London last week. [...] IBM has already done proof-of-principle experiments (PDF) showing that integrated circuits based on "complementary metal oxide semiconductor" (CMOS) technology can be installed next to the cold qubits to control them with just tens of milliwatts. Beyond that, he admits, the technology required for quantum-centric supercomputing does not yet exist: that is why academic research is a vital part of the project.

The qubits will exist on a type of modular chip that is only just beginning to take shape in IBM labs. Modularity, essential when it will be impossible to put enough qubits on a single chip, requires interconnects that transfer quantum information between modules. IBM's "Kookaburra," a 1,386-qubit multichip processor with a quantum communication link, is under development and slated for release in 2025. Other necessary innovations are where the universities come in. Researchers at Tokyo and Chicago have already made significant strides in areas such as components and communication innovations that could be vital parts of the final product, Gambetta says. He thinks there will likely be many more industry-academic collaborations to come over the next decade. "We have to help the universities do what they do best," he says.

"China delivered the latest salvo in an escalating semiconductor war with the U.S.," reports Bloomberg, "announcing that Micron Technology Inc. products have failed to pass a cybersecurity review in the country." In a statement Sunday, Beijing warned operators of key infrastructure against buying the company's goods, saying it found "relatively serious" cybersecurity risks in Micron products sold in the country. The components caused "significant security risks to our critical information infrastructure supply chain," which would affect national security, according to the statement from the Cyberspace Administration of China, or CAC...

Chinese officials privately say that the probe of Micron is part of a broader trend toward the dominance of "pro-retaliation" voices in Beijing, where national security concerns increasingly trump economic arguments. "No one should understand this decision by CAC as anything but retaliation for the US's export controls on semiconductors," said Holden Triplett, founder of Trenchcoat Advisors and a former FBI counterintelligence official in Beijing. "No foreign business operating in China should be deceived by this subterfuge. These are political actions pure and simple, and any business could be the next one to be made an example of." The move brings fresh uncertainty to the other US chipmakers that sell to China, the world's biggest market for semiconductors.
The article notes pointedly that memory chips "aren't usually considered a cybersecurity risk because they don't require any specific software or run code. They're mostly basic grids of transistors used for storing data and, as such, haven't typically been a vector of attack for hackers." The Associated Press describes China's move as "stepping up a feud with Washington over technology and security," adding that Chinese officials "appear to be struggling to find ways to retaliate without hurting China's smartphone producers and other industries and efforts to develop its own processor chip suppliers," which import more than $300 billion in foreign chips every year. An official review of Micron under China's increasingly stringent information security laws was announced April 4, hours after Japan joined Washington in imposing restrictions on Chinese access to technology to make processor chips on security grounds. Foreign companies have been rattled by police raids on two consulting firms, Bain & Co. and Capvision, and a due diligence firm, Mintz Group. Chinese authorities have declined to explain the raids but said foreign companies are obliged to obey the law.

From Street Fighter 6 to Mortal Kombat 1, 2023 offers a robust slate of big, brawling attractions. From a report: The pandemic stole one of gaming's purest experiences: karate chopping your buddy in the stomach and laughing as their health meter falls to zero. The culture around fighting games -- side by side on a couch or in a whirring arcade -- doesn't translate so well to Zoom. It didn't help that a lot of the online play technology for these games has for years fallen short of expectations. Few mainstream fighting games were released over the last three years. But in 2023, fighting games are returning with a vengeance. The list includes Capcom's Street Fighter 6, Warner Bros Games' just-announced Mortal Kombat 1 and Cygames' Granblue Fantasy Versus: Rising. Fans are also hoping to get Project L from Tencent's Riot Games and Tekken 8 from Bandai Namco Studios sometime in the not too distant future. "Rather than trash talking online, it's a lot better to do in person," Street Fighter 6 producer Shuhei Matsumoto told me in an interview this week. We were talking about what his highly-anticipated game, launching June 2, and the broader fighting genre has learned from the pandemic disruptions.

The new Street Fighter aims to bring what people love about in-person gaming into the online arena. 2016's Street Fighter 5 famously didn't have the best online experience. "For 5, the team acknowledged there were some issues with the existing net code," Matsumoto said. "As a team, we all agreed that something had to be done for Street Fighter 6." Capcom put together a specialized team to improve the online experience for Street Fighter 6. The team also aimed to upload facets of the culture of Street Fighter. In previous Street Fighter games, the main thing online contenders had to size up their opponent was their gamer tag. Street Fighter 6 has a Battle Hub, which game director Takayuki Nakayama said "is like an extension of arcade culture." Players can now dress up their avatars and show off their outfits while congregating with friends -- a process that Nakayama said can "humanize" online competitors. The culture of fighting games has changed a lot since 2020. Arcades in Japan, where Capcom traditionally debuted its latest titles, shuttered at a rapid fire rate -- a trend that began pre-Covid but accelerated during the lockdowns. Meanwhile, money has bled out of the esports industry, which funded local, national and international tournaments. 2023 promises to reinvigorate fighting games. Capcom's Pro Tour has a $2 million prize pool. "I would say it's fully bounced back and then some," said Alec Polsley, who owns my local LAN cafe. On weekends, the place is teeming with competitors leaning over sweaty controllers.

IBM and Google are giving $150 million for quantum-computing research at the University of Chicago and the University of Tokyo as the U.S. and Japan try to stay ahead of a fast-rising China. From a report: Quantum computers are a hot area of research because they could help solve problems that classical computers alone can't, such as modeling how a drug molecule interacts with the body's proteins or how batteries work at an atomic scale. China has invested heavily in quantum computing, which also has possible military applications in cryptology and materials for weapons. U.S. researchers said Chinese laboratories have shown progress recently -- often touted in state media -- and are competitive in some areas. However, quantum-computing specialists say more basic study is needed before anyone can be sure the technology delivers real-world benefits.

The U.S.-Japan partnership is an example of how scientific research with implications for security and economic growth is increasingly split between China and a U.S.-led camp that includes allies such as Japan and Western European nations. "We have to count on our allies more for primary research," said Rahm Emanuel, the U.S. ambassador to Japan. Until recently, he said, the U.S. was too lax in allowing Chinese students to work at American universities in advanced scientific fields. "We were funding them. We were not only funding them, we were training them, educating them to come back and compete against us," he said.

CNET explores the potential of "marine energy," starting with "an ambitious endeavor nearing completion off the coast of Oregon, where 7 miles of conduit were laid under the floor of the Pacific Ocean using pioneering horizontal drilling techniques." Soon, thick cables will be run through that conduit to connect the mainland to PacWave, an offshore experimental testbed built to develop and demonstrate new technology that converts the power of waves into onshore electricity. Once fully operational (as soon as 2025), PacWave could generate up to 20 megawatts, enough to power a few thousand homes.

"I get really excited about wave energy because the resource is so large," Levi Kilcher, a senior scientist with the National Renewable Energy Laboratory, told me. Kilcher is a lead author on the 2021 National Renewable Energy Laboratory (NREL) report that compiled available data on marine energy sources in the US, including waves, tides and ocean currents. The team found that the total energy potential is equal to more than half (57%) of the electricity generated in the U.S. in a single year...

Waves are just one potential source of marine energy that scientists and officials are investigating. Andrea Copping, a senior researcher at the Pacific Northwest National Laboratory, says there's renewed interest in another form of marine energy: ocean thermal energy conversion, or OTEC, which involves bringing up colder water from deeper parts of the ocean. This chilly flow then goes through a heat exchange process with warmer surface water, similar to the way home heat pumps exchange hot and cold air. That process drives a turbine to generate electricity... A small OTEC plant has been functioning in Hawaii for years. Copping believes new commitments from the U.S. government hold promise for the future of the technology, which has also seen significant interest in Japan and other surrounding nations.

It's possible that concern over climate change could unlock new sources of funding for OTEC... There's also the added bonus that the cold water pipes can double as a form of air conditioning in the tropical locales where OTEC works best.

Toyota Japan has apologized after admitting to leaving millions of customers' vehicle details on the public internet for a decade. From a report: The car maker said in a notice that it will notify about 2.15 million customers whose personal and vehicle information were left exposed to the internet after a "cloud misconfiguration" was discovered recently in April. Toyota said that the exposed data includes: registered email addresses; vehicle-unique chassis and navigation terminal numbers; the location of vehicles and what time they were there; and videos from the vehicle's "drive recorder" which records footage from the car. Toyota said the data spilling from its Connected Cloud (TC) was initially exposed in November 2013, but pertains only to vehicles in Japan, according to the company. The company's connected service provides Toyota customers with information about their vehicle, provides in-car entertainment services, and helps to notify authorities in the event of an accident or breakdown.

Friday Bill Gates visited Kemmerer, Wyoming (population: 2,656) — where a coal plant was shutting down after 50 years. But Gates was there "to celebrate the latest step in a project that's been more than 15 years in the making: designing and building a next-generation nuclear power plant..."

The new plant will employ "between 200 and 250 people," Gates writes in a blog post, "and those with experience in the coal plant will be able to do many of the jobs — such as operating a turbine and maintaining connections to the power grid — without much retraining." It's called the Natrium plant, and it was designed by TerraPower, a company I started in 2008. When it opens (potentially in 2030), it will be the most advanced nuclear facility in the world, and it will be much safer and produce far less waste than conventional reactors.

All of this matters because the world needs to make a big bet on nuclear. As I wrote in my book How to Avoid a Climate Disaster , we need nuclear power if we're going to meet the world's growing need for energy while also eliminating carbon emissions. None of the other clean sources are as reliable, and none of the other reliable sources are as clean...

Another thing that sets TerraPower apart is its digital design process. Using supercomputers, they've digitally tested the Natrium design countless times, simulating every imaginable disaster, and it keeps holding up. TerraPower's sophisticated work has drawn interest from around the globe, including an agreement to collaborate on nuclear power technology in Japan and investments from the South Korean conglomerate SK and the multinational steel company ArcelorMittal...

I'm excited about this project because of what it means for the future. It's the kind of effort that will help America maintain its energy independence. And it will help our country remain a leader in energy innovation worldwide. The people of Kemmerer are at the forefront of the equitable transition to a clean, safe energy future, and it's great to be partnering with them.
Gates writes that for safety the plant uses liquid sodium (instead of water) to absorb excess heat, and it even has an energy storage system "to control how much electricity it produces at any given time..."

"I'm convinced that the facility will be a win for the local economy, America's energy independence, and the fight against climate change.
