Sweden Scraps Plans For 13 Offshore Windfarms Over Russia Security Fears

An anonymous reader quotes a report from The Guardian: Sweden has vetoed plans for 13 offshore windfarms in the Baltic Sea, citing unacceptable security risks. The country's defence minister, Pal Jonson, said on Monday that the government had rejected plans for all but one of 14 windfarms planned along the east coast. The decision comes after the Swedish armed forces concluded last week that the projects would make it more difficult to defend Nato's newest member. The proposed windfarms would have been located between Aland, the autonomous Finnish region between Sweden and Finland, and the Sound, the strait between southern Sweden and Denmark. The Russian exclave of Kaliningrad is only about 310 miles (500km) from Stockholm. Wind power could affect Sweden's defence capabilities across sensors and radars and make it harder to detect submarines and possible attacks from the air if war broke out, Jonson said. The only project to receive the green light to was Poseidon, which will include as many as 81 wind turbines to produce 5.5 terawatt hours a year off Stenungsund on Sweden's west coast. "Both ballistic robots and also cruise robots are a big problem if you have offshore wind power," Jonson said. "If you have a strong signal detection capability and a radar system that is important, we use the Patriot system for example, there would be negative consequences if there were offshore wind power in the way of the sensors."

America's First Sodium-Ion Battery Gigafactory Announced. Cost: $1.4 Billion

Sodium-ion batteries are cheaper than lithium-ion batteries — and they're also more environmentally friendly. And "In the past few years, sodium-ion battery production has increased in the United States," reports the Washington Post, with a new factory planned to manufacture them "in the same way as lithium-ion batteries, just with different ingredients. Instead of using expensive materials like lithium, nickel and cobalt, these will be made of sodium, iron and manganese..." Last month, sodium-ion battery manufacturer Natron Energy announced it would open a "gigafactory" in North Carolina that would produce 24 gigawatt hours of batteries annually, enough energy to charge 24,000 electric vehicles. But sodium-ion batteries are still early in their development compared with lithium-ion, and they have yet to hit the market on a massive scale. "It's unlikely sodium-ion could displace lithium-ion anytime soon," said Keith Beers, polymer science and materials chemistry principal engineer at technical consultancy firm Exponent... The biggest limitation of sodium-ion batteries is their weight. Sodium weighs nearly three times as much as lithium, and it cannot store the same amount of energy. As a result, sodium-ion batteries tend to be larger. Jens Peters, an economics professor at the University of Alcalá in Madrid, said the energy density could be improved over time in sodium-ion batteries. But, he added, "what we found out so far in our assessments is that it is not a game changer." Sodium-ion batteries are touted to be the environmentally friendly alternative to their lithium-ion counterparts, thanks to their raw materials. Sodium, iron and manganese are all abundant elements on the planet, so they require less energy to extract and cost less... Sodium-ion batteries also last longer than lithium-ion ones because they can withstand more charge cycles, said Wendell Brooks, co-CEO of Natron Energy. "Our product can have millions of cycles," said Brooks, "where lithium-ion would have three to five thousand cycles and wear out a lot faster...." Sodium-ion batteries aren't the best fit for smartphones or electric vehicles, which need to store lots of energy. However, one advantage is their low cost. And they could be a good candidate in situations where the size of the battery isn't a concern, like energy storage. "When something is built out to support grid or backup storage, it doesn't need to be very dense. It's staying put," Beers said. Natron will invest nearly $1.4 billion in the factory "to meet the rapidly expanding demand for critical power, industrial and grid energy storage solutions," according to their announcement. "Natron's high-performance sodium-ion batteries outperform lithium-ion batteries in power density and recharging speed, do not require lithium, cobalt, copper, or nickel, and are non-flammable... Natron's batteries are the only UL-listed sodium-ion batteries on the market today, and will be delivered to a wide range of customer end markets in the industrial power space, including data centers, mobility, EV fast charging, microgrids, and telecom, among others."

Cuba's Power Grid Collapses Again After Second Hurricane. And Then an Earthquake Hit

Wednesday Cuba was hit by a major hurricane which took down its entire power grid again, this time for about 24 hours, according to CNN: Videos of the aftermath showed power infrastructure turned into a mangled mess and power poles down on streets. Hundreds of technicians were mobilized Thursday to reestablish power connections, according to state media... Operations at two electrical plants were partially restored and parts of eastern and central Cuba had electricity back up by Thursday afternoon, state media reported... The country's power grid has collapsed multiple times, including when Hurricane Oscar hit in October and killed at least 7 people. In the capital of Havana, where 2 million people live, power had been restored to less than 20% of the city by late Friday afternoon, . "Authorities had not yet given an estimate for when power would be fully restored..." Then tonight, CNN reported: A 6.8 magnitude earthquake struck off the coast of eastern Cuba on Sunday, causing material damage in several regions as the island continues to recover from widespread blackouts and the impact of two hurricanes over the past few weeks. The earthquake was reported about 39 km (24 miles) south of Bartolomé Masó before noon local time, about an hour after a 5.9 magnitude quake rocked the area, the United States Geological Survey (USGS) said. "There have been landslides, damage to homes and power lines," Cuban President Miguel Díaz-Canel said, adding that authorities are evaluating the situation to start recovery efforts.

Can AI-Enabled Thermostats Create a 'Virtual Power Plant' in Texas?

Renew Home says they're building a "virtual power plant" in Texas by "enabling homes to easily reduce and shift the timing of energy use." Thursday they announced a 10-year project distributing hundreds of thousands of smart thermostats to customers of Texas-based power utility NRG Energy, starting next spring. (Bloomberg calls them "AI-enabled thermostats that use Alphabet Inc.'s Google Cloud technology.") The ultimate goal? "Create a nearly 1-gigawatt, AI-powered virtual power plant" — equivalent to 1.9 million solar panels, enough to power about 200,000 homes during peak demand. One NRG executive touted the move as "cutting-edge, AI-driven solutions that will bolster grid resilience and contribute to a more sustainable future." [Residential virtual power plants] work by aggregating numerous, small-scale distributed energy resources like HVAC systems controlled by smart thermostats and home batteries and coordinating them to balance supply and demand... NRG, in partnership with Renew Home, plans to offer Vivint and Nest smart thermostats, including professional installation, at no cost to eligible customers across NRG's retail electricity providers and plans. These advanced thermostats make subtle automatic HVAC adjustments to help customers shift their energy use to times when electricity is less constrained, less expensive, and cleaner... Over time, the parties expect to add devices like batteries and electric vehicles to the virtual power plant, expanding energy savings opportunities for customers... Through the use of Google Cloud's data, analytics, and AI technology, NRG will be able to do things like better predict weather conditions, forecast wind and solar generation output, and create predictive pricing models, allowing for more efficient production and ultimately ensuring the home energy experience is seamless for customers. Google Cloud will also offer "its AI and machine learning to determine the best time to cool or heat homes," reports Bloomberg, "based on a household's energy usage patterns and ambient temperatures." It was less than a year ago that Renew Home was formed when Google spun off the load-shifting service for its "Google Nest" thermostats, which merged with load-shift management startup OhmConnect. Bloomberg describes this week's announcement as "Three of the biggest names in US home energy automation... coming together to offer some relief to the beleaguered Texas electrical grid." But they point out that 1 gigawatt is roughly 1% of the record summer demand seen in Texas this year. Still, "The entire industry has been built to serve the peak load on the hottest day of the year," said Rasesh Patel, president of NRG's consumer unit. "This allows us to be a lot more smarter about demand in shaving the peak."

LG's New Stretchable Display Can Grow By 50%

An anonymous reader quotes a report from Tom's Hardware: LG Display, one of the global leaders in display technologies, unveiled a new stretchable display prototype that can expand by up to 50%. This makes it the most stretchable display in the industry, more than doubling the previous record of 20% elongation. [...] The prototype being flexed in [this image] is a 12-inch screen with a 100-pixel-per-inch resolution and full RGB color that expands to 18-inches when pulled. LG Display said that it based the stretchable display on a "special silicon material substrate used in contact lenses" and then improved its properties for better "stretchability and flexibility." It also used a new wiring design structure and a micro-LED light source, allowing users to repeatedly stretch the screen over 10,000 times with no effect on image quality.

At 30 years old, is Ruby in a mid-life crisis or a renaissance?


Ruby’s creator, Yukihiro Matsumoto (Matz), released the first public version of the programming language in December 1995, making Ruby just shy of its 30th birthday. It spread across Japanese-language Usenet newsgroups, a popular way of exchanging conversation and media before the World Wide Web, and then reached broader communities throughout the late 1990s. This was thanks to Ruby’s friendly community and, in no small part, thanks to Matz. (The community has a motto, “Matz is nice, and so we are nice.”) At this year’s annual European Ruby Konferenze — EuRoKu — in Sarajevo, Matz said he created Ruby because he…
