Huawei Digital Power now rivals Tesla’s energy division in revenue

Rain supercharges 5G with Huawei

Rain South Africa và Huawei triển khai mạng 5G massive MIMO băng tần dưới 1GHz trên quy mô lớn tại Nam Phi, lần đầu tiên thương mại hóa công nghệ này trong băng tần FDD sub-1GHz. Kết quả thử nghiệm cho thấy cải thiện phủ sóng uplink 5dB, downlink 3dB và tăng dung lượng mạng gấp 3 lần so với thiết bị 4T4R truyền thống, thiết lập chuẩn mực mới cho tiến hóa mạng 5G toàn cầu.

Lập trình viên nên đọc bài này để hiểu cách hệ thống MIMO lớn trên băng tần sub-1GHz được tối ưu hóa trong 5G, giúp giải quyết vấn đề phủ sóng rộng và tăng hiệu suất mạng cho các ứng dụng di động và IoT, đặc biệt quan trọng trong thiết kế phần mềm cho các hệ thống hạ tầng viễn thông và ứng dụng công nghệ mới.

AI's gas-plant boom, and the fight to stop it

AI data centres have triggered the largest-ever natural gas power plant construction boom, with some facilities consuming as much electricity as mid-size cities. Wind and solar cannot scale fast enough to meet demand, forcing utilities and governments to keep aging coal plants running past retirement. Several US states are responding with legislation tying data centre tax incentives to renewable energy benchmarks. Clean-energy advocates, unable to outbuild the boom, are targeting regulators instead — pushing for rules that let large power users build their own clean generation and connect it to the grid. Google and others have struck deals to add geothermal, wind, and solar capacity in exchange for grid access. Grid interconnection queues, not legislatures, are seen as the decisive battleground, with policy decisions made now likely to shape energy infrastructure for two to three decades.

Quaise raises $134M to drill superhot geothermal

Quaise Energy has closed a $134M first tranche of its Series B, led by Prelude Ventures with participation from Japanese energy firms JERA and Idemitsu, bringing total funding to $230M. The startup uses millimetre-wave microwave beams — technology originating from MIT research — to vaporise rock at depths beyond 5km, reaching temperatures of 300–500°C that conventional drill bits cannot access. The funds will go toward Project Obsidian in Oregon, targeting the world's first commercial superhot geothermal plant with grid power delivery by 2030. A hyperscaler has already signed for the first 50MW of output. The company's test site in Texas has reached nearly 1km depth, still far short of the 5km+ target, leaving the core engineering challenge unproven at commercial scale. The raise reflects surging investor interest in always-on clean power driven by AI data centre demand.

Hydrogen: clean fuel of the future — if we can find a cheap and clean way to ship it

Các nhà nghiên cứu từ MIT Energy Initiative đã phát triển HyCAT, một công cụ mã nguồn mở giúp so sánh chi phí và lượng khí thải carbon của các phương pháp vận chuyển hydrogen. Công cụ này mô hình hóa năm bước trong chuỗi cung ứng (hóa lỏng, lưu trữ, vận chuyển, nhập khẩu lưu trữ và tái khí hóa) và hỗ trợ phân tích bốn phương thức vận chuyển: hóa lỏng trực tiếp, chất mang dựa trên toluene, methane tổng hợp và ammonia. Tùy thuộc vào địa lý, chi phí năng lượng và cơ sở hạ tầng, ammonia được coi là phương án hứa hẹn nhất nhờ cơ sở hạ tầng đã được thiết lập sẵn.

Lập trình viên nên đọc bài này để hiểu cách xây dựng công cụ phân tích chi tiết về chuỗi cung ứng hydrogen—chính xác cho các quyết định kỹ thuật, kinh tế và môi trường trong tương lai năng lượng sạch.

Four nuclear reactors hit a big milestone in the US

Four US microreactor companies — Antares Nuclear, Valar Atomics, Deployable Energy, and Aalo Atomics — achieved zero-power criticality ahead of a Trump administration deadline tied to the nation's 250th birthday. All four were selected under the DOE's Reactor Pilot Program, which fast-tracks prototype development. However, zero-power criticality is a limited milestone: it confirms a sustained chain reaction is possible but produces no electricity and requires significant additional engineering work, including cooling systems. Companies are projecting commercial timelines of 2027–2028, though regulatory hurdles from the NRC remain uncertain. Some nuclear policy analysts argue the microreactor focus is a distraction from scaling up meaningful grid capacity.

US may scrap the steering-wheel rule for driverless cars

The US and EU are taking opposite approaches to vehicle safety regulation. The US NHTSA is considering dropping the steering wheel requirement for fully driverless cars, benefiting companies like Tesla with its Cybercab. Meanwhile, the EU has mandated driver-monitoring cameras in all new cars sold in the bloc, tracking eye and face movements to detect inattention. The philosophical divide is stark: the US bets that removing humans from the loop eliminates human error, while Europe bets on monitoring human drivers more closely. Both approaches carry risks — no manual override in a driverless car emergency, and privacy concerns around in-car facial surveillance cameras.

Tesla's Cybercab car park lap isn't the real story

Tesla announced Cybercab employee rides 'starting soon' at Giga Texas, accompanied by a video of the vehicle driving itself across a parking lot. The real story, however, is a regulatory shift: two days earlier, the NHTSA administrator signaled willingness to scrap the rule requiring driverless vehicles to have steering wheels and manual controls. This is the legal constraint that has kept the Cybercab in a grey zone. Tesla has deliberately avoided applying for individual exemptions (capped at 2,500 vehicles/year), betting instead that federal rules would change broadly. That bet appears to be paying off. Meanwhile, Tesla's Austin robotaxi fleet of 42 vehicles lags far behind Waymo's 577, and its FSD crash rate is roughly four times worse than the human average. The parking lot video is marketing motion for a product that can't yet be legally or reliably deployed at scale on public roads.
