12:02a	Best Buy's New $200/Yr Membership Locks PS5, Hot Holiday Items Behind Membership An anonymous reader quotes a report from Ars Technica: If you're still searching for a PS5 and are a Best Buy customer, your ship may have just come in -- that is, if you're willing to spend an extra $200 a year for access. That's because the big-box electronics retailer is locking stock of in-demand holiday items like Sony's console behind membership of its new Totaltech program. The expensive customer service package was recently rolled out nationwide. The $200 annual service -- which has benefits like round-the-clock tech support, up to two years of protection on Best Buy purchases (including AppleCare+ insurance, which can cost $200 on its own), and member discounted prices -- is throwing in exclusive access to "the season's hardest-to-find products" as a bonus perk for the holidays, the company said in a statement. The Best Buy retail site had the $500 disc drive model PS5s available for Totaltech members to buy Monday morning, with the consoles gated behind an "exclusive access event" paywall. Instead of selling out instantly, its stock lasted between 90 minutes and two hours -- a relatively glacial sales pace compared to the insane demand for the hardware that consumers have faced since it hit stores last November. Although the PS5's listing page pointed directly to Totaltech membership exclusivity while the hardware was still available, its seemingly unrelated VIP buying privileges aren't listed anywhere on the program's membership benefits and FAQ pages. We would not be shocked to see other highly desired products that have been affected by the chip shortage follow suit, particularly high-end PC GPUs and Xbox Series X/S consoles. The service is replacing a "Best Buy Beta" program that was tested in select markets starting in April. Beta seemed to target a more generalized range of benefits over one focused on tech support and protection, and it notably did not offer special members-only events to buy limited-stock electronics. The company's free My Best Buy membership, which sometimes includes exclusive discount sales, remains unaffected. Read more of this story at Slashdot. (Comment on this)
12:45a	Robotics Engineer Adds a Working USB-C Port To An iPhone Ken Pillonel, a robotics engineer on YouTube, replaced an iPhone's Lightning port with a working USB-C port. AppleInsider reports: In a YouTube Short titled "World's First USB-C iPhone," Ken Pillonel claims to have installed the component into the iPhone X, replacing Lightning in the process. In the video, the iPhone is said to receive power via the connection, as well as being able to handle data transfers over a USB-C cable. In the description of the video, Pillonel says he reverse-engineered Apple's C94 connector, in order to make a PCB with a female USB-C port. After the schematics were set in place, it then became a challenge to shrink it down and install it into an iPhone. Pillonel has spent a few months on his creation, with a blog post from May showing the thinking behind the replacement, and the challenges of replacing the Lightning port itself. A video at that time showed a DIY prototype that worked and laid out the work ahead to make it small enough to work within an iPhone enclosure. A late September update advised he had designed and ordered a flexible PCB, a key component in enabling the port switch to occur. He adds a future video is in production, explaining how the board was made and squeezed into the iPhone itself. Read more of this story at Slashdot. (Comment on this)
3:30a	Solar Panels On Half the World's Roofs Would Power the Planet An anonymous reader quotes a report from The Conversation: Our new paper in Nature Communications presents a global assessment of how many rooftop solar panels we'd need to generate enough renewable energy for the whole world -- and where we'd need to put them. Our study is the first to provide such a detailed map of global rooftop solar potential, assessing rooftop area and sunlight cover at scales all the way from cities to continents. We found that we would only need 50 percent of the world's rooftops to be covered with solar panels in order to deliver enough electricity to meet the world's yearly needs. We designed a program that incorporated data from over 300 million buildings and analyzed 130 million km of land -- almost the entire land surface area of the planet. This estimated how much energy could be produced from the 0.2 million km of rooftops present on that land, an area roughly the same size as the U.K. We then calculated electricity generation potentials from these rooftops by looking at their location. Generally, rooftops located in higher latitudes such as in northern Europe or Canada can vary by as much as 40% in their generation potential across the year, due to big differences in sunshine between winter and summer. Rooftops near the equator, however, usually only vary in generation potential by around 1% across the seasons, as sunshine is much more consistent. This is important because these large variations in monthly potential can have a significant impact on the reliability of solar-powered electricity in that region. That means places where sunlight is more irregular require energy storage solutions -- increasing electricity costs. Our results highlighted three potential hotspots for rooftop solar energy generation: Asia, Europe and North America. Of these, Asia looks like the cheapest location to install panels, where -- in countries like India and China -- one kilowatt hour (kWh) of electricity, or approximately 48 hours of using your laptop, can be produced for just 0.05p. This is thanks to cheap panel manufacturing costs, as well as sunnier climates. Meanwhile, the costliest countries for implementing rooftop solar are the U.S., Japan and the U.K. Europe holds the middle ground, with average costs across the continent of around 0.096p per kWh. The report mentions this endeavor would be "extremely expensive," and won't be a solution for some industries that require very large currents and specialized electricity delivery. However, the report concludes by saying: "If the costs of solar power continue to decrease, rooftop panels could be one of the best tools yet to decarbonize our electricity supply."
