AI claims to break a 30-year computing belief, Nvidia's Rubin ships slower than promised, and a rocket shortage, plus 3 India stories

Before, India's surplus daytime solar was often wasted or curtailed. Grid batteries shift it to the evening peak. More large tenders are open (SECI 3.2 GWh (gigawatt-hour, a measure of stored energy), Andhra Pradesh 5 GWh).

A 500 megawatt hour battery in Rajasthan just started work. IndiGrid's 250 megawatt, 500 megawatt hour battery in Rajasthan began commercial operation on October 27. First, it charges when solar power is cheap at midday. Second, it discharges in the evening peak under a 12 year contract with N V V N. Cells are mostly imported, and contract income is fixed. Our judgment: promising, start small.

Before, small electric water purifiers wasted most of their energy heating water they never evaporated. This design heats only a thin layer. It is a lab prototype; scaling to village or city volumes is unproven.

A palm-sized solar gadget made drinking water from salty, oily and acidic water. Researchers in Nature Water showed a solar evaporator that made 1.64 litres of fresh water in 8 hours. First, sunlight powers a heated mesh layer that warms only a thin sheet of water. Second, the vapour is collected as clean water, leaving salt and dirt behind. It is a small lab device, not yet tested at scale. Our judgment: too early.

Before, growers walked the rows looking for pests by eye. Sensors and cameras can catch problems earlier and predict yields. It is a small seed round in a crowded field.

A Berlin startup raised 4.8 million euros to spot greenhouse pests with A I. hexafarms raised 4.8 million euros for wireless crop sensors and AI that scouts greenhouses for pests and disease. First, sensors and cameras collect data across the greenhouse. Second, AI flags pests early and forecasts the harvest. It is a small seed round in a crowded field. Our judgment: too early.

Before, Android XR had no glasses on sale. Now Google's platform has real hardware, competing with Meta's glasses. Price and the wired puck limit it to early adopters.

The first glasses running Google's Android XR are on sale. Xreal's Aura glasses went on order October 28 from 1,099 dollars and ship from mid-November. First, a small computer in your pocket runs Android apps. Second, the glasses show them on a sharp screen that seems to float in front of you. High price and the wired puck limit buyers. Our judgment: too early.

Before, most carbon-removal deals were small, one-off purchases. Long contracts let projects borrow money and scale. Tree-based removal can be reversed by fire or land-use change, so checking is key.

Google and McKinsey will buy 320 thousand tonnes of carbon removal over 10 years. Google and McKinsey signed 10-year deals for 320 thousand tonnes of carbon removal from trees on Brazilian pasture. First, farmers plant trees among cattle pasture. Second, the carbon the trees store is measured and sold as credits. Trees can burn, and the price is not public. Our judgment: too early.

Before, this drug had data in one species. Now there is a second species, but with very small groups and company-reported results. Most anti-ageing drugs that work in animals fail in people.

A company says its anti-ageing drug kept very old rats moving well. Eos SENOLYTIX reports that very old rats on PTC-2105 kept their balance-beam scores near where they started. First, the peptide targets the cell's power units, called mitochondria. Second, it is meant to clear out worn-out cells that cause inflammation. It is company-reported and not checked by other scientists. Our judgment: too early.

Before, quantum-safe encryption was a recommendation. Now there are firm dates and big cloud providers ship it. The threat is 'harvest now, decrypt later': attackers store data today to read once quantum computers arrive.

The US just fixed the dates for switching to quantum-safe encryption. NIST published its final roadmap, NISTIR 8547, with deadlines of 2030 and 2031 for the most sensitive US systems. First, organisations list every place old encryption is used. Second, they swap in the new NIST methods, like the one AWS just added. Audits show agencies are behind, so spending may be slow. Our judgment: promising, start small.

Before, drones were bought in small emergency batches. This approval puts drones and counter-drones into the big, planned budget. In-principle approval is the first of several steps; contracts can take years.

India just approved over two lakh crore rupees of defence buying, with drones at the centre. On October 26 India's Defence Acquisition Council approved 2.12 lakh crore rupees of proposals, about 82 percent from Indian industry. First, each item goes out to tender. Second, the winning firms sign contracts and start deliveries. This is approval in principle only, and contracts can take years. Our judgment: promising, start small.

Before, fusion firms bought off-the-shelf power electronics. Helion needs switches that handle huge, fast pulses, so it will make its own. It is a letter of intent, not a final award, and fusion power has not yet been sold to the grid.

A fusion startup may get up to 175 million dollars of US chip money. Helion signed a letter of intent for up to 175 million dollars from the US CHIPS office, plus 50 million private. First, the money funds chip and packaging research in Washington state. Second, the chips switch huge pulses of power in Helion's fusion machines. It is a letter of intent, not a final deal, and no fusion firm sells power yet. Our judgment: too early.

Before, driverless rides were limited to small zones. Bigger zones and more cars mean robotaxis start to compete with normal ride-hailing. Waymo is still unprofitable, and fleet targets are reported, not guaranteed.

Waymo's driverless taxis now cover about 250 more square miles in five US cities. Waymo is expanding robotaxi service across Los Angeles, Nashville, Orlando, San Diego and the Bay Area. First, cars are mapped and tested in each new area. Second, the zone opens to paying riders who book through the app. Waymo is still unprofitable, and fleet numbers are press reports. Our judgment: promising, start small.

Before, humanoids were mostly demos and small pilots. If sales start, factories could buy general-purpose robots instead of single-task machines. It is a CEO forecast, and Tesla's past timelines have often slipped.

Tesla says its humanoid robot could go on sale to other companies by the end of 2027. On its October 21 earnings call, Tesla said Optimus could ship to outside companies by the end of 2027. First, the robot learns tasks by watching and practice in Tesla's own plants. Second, outside buyers would pay for it to do repetitive jobs like moving parts. No price, customer or volume was given, and Tesla timelines often slip. Our judgment: too early.

Before, ETH was treated as true and used to argue that many problems can never get much faster. If the claim holds, those arguments need rechecking, though the new method may only beat brute force on enormous problems (Anthropic's paper suggests more than 10 million variables). OpenAI says it seeks no academic credit and will fund a conference. Separately, Papex reports OpenAI withdrew three AI-produced Hodge-conjecture papers after a sign error, a reminder that AI proofs can be wrong.

OpenAI and Anthropic each say their AI disproved a 30-year-old computing belief; outside experts have started checking. Like a climber saying they reached a peak the guidebooks called unclimbable: the GPS log (the Lean check) shows a real route, but experts still have to confirm it is the same peak the guidebook meant.

AI models often wait on memory, not compute, so memory speed matters for real performance. ServeTheHome suggests the likely cause is HBM4 memory not reaching Nvidia's very aggressive speed, though Nvidia's revised 9.4 Gbps per pin is still above AMD's MI455X (7.6 Gbps). Rubin is shipping on schedule, and the change applies to all Rubin hardware from day one.

Nvidia's Rubin AI chip ships with 11% less memory speed and 17% less chip-to-chip speed than first promised. Like a new highway opening with all its promised lanes but a lower speed limit on the ramps to the warehouse: the trucks (compute) are as big as advertised, but goods move to and from storage (memory) a bit slower. Our judgment: watch. Sources on our page.

Faster gates mean more operations fit before a qubit loses its information, which matters for error correction. Before, going faster raised leakage errors that error correction handles badly. The result is for single qubits; crosstalk between many qubits on a real chip is still a challenge.

German researchers run quantum logic steps in 6.8 billionths of a second with 99.98% accuracy. Like a pianist playing a fast passage without brushing the neighbouring keys: speed usually causes wrong notes, and the new finger technique (pulse shape) keeps every stroke on the right key.

Before, speech decoding needed a button press and stayed inside one app. Neuralink says only participants can judge whether designs work, since no engineer has an implant. All features are prototypes, with no measured results for calls or dictation yet.

Neuralink's speech-implant user makes iPhone calls and types in any app in a 72-hour home test. Like fitting a hearing aid with Bluetooth: the core device already works, but it becomes truly useful once it connects directly to the phone and apps people use every day. Our judgment: wait.

Solid-state batteries replace the liquid inside cells with a solid, promising more range and better safety. The hard part is keeping solid layers in tight contact as they charge. A 20 Ah cell is still much smaller than many car cells (our judgment), and output will be limited until about 2030.

CATL starts 20 Ah trial cells of its all-solid-state EV battery, aiming for 500 Wh/kg and small-scale output in 2027. Like a shipyard moving from scale models to its first full-size test hulls: the design floats in the lab, but a working fleet (mass production) is still years away. Our judgment: watch.

Before, Falcon 9 carried most Western commercial satellites. Now buyers must wait for new rockets to fly often. Quilty's research director said: if you need a launch and haven't booked, you're late. Rocket makers with working, available rockets could see strong demand (our judgment).

Analysts see a shortage of about 150 rocket launches outside China through 2030. Like an airport where the busiest airline retires its main jet just as bookings boom: new planes are late, so seats sell out for years. Our judgment: watch. Sources on our page.

UPI keeps growing fast, which strengthens India's digital-payments lead. But most UPI payments are free for users and merchants, so payment apps earn little from them directly; the pending MDR decision matters for their income (our judgment).

UPI moves over ₹1 lakh crore a day on average for the first time, in a record October. Like a national railway on its busiest festival day, except it happened every day of the month: 821 million trips (payments), each one tiny, adding up to a record load. Our judgment: watch. Sources on our page.

Before, most AI models were built mainly for English and handled Indian languages through translation or light extra training. BharatGen says Param2 learned Indian languages natively. No independent benchmark results were given, and the insurance time savings (hours to under five minutes) are from the presentation.

India's BharatGen Param2 model, built from scratch for 22 Indian languages, is now running in government and insurance apps. Like a large orchestra where only the few sections needed for each tune play: the full band (17 billion parameters) is on stage, but only about 2.4 billion play each note, so the concert costs less to run. Our judgment: watch. Sources on our page.

India wants AI computing and data kept inside the country (data localisation). Most new AI chips need liquid cooling and lots of power, so ready power and cooling are a real advantage (our judgment). Data centres are a small part of L&T's business.

L&T's Vyoma.AI breaks ground on a 52 MW liquid-cooled AI data centre in Chennai. Like building a bigger power-hungry factory next to an existing one, with coolant pipes running straight to each machine: AI servers run so hot that air alone cannot cool them. Our judgment: watch.

Before, surgery was the main option and the virus stayed in the tissue, so many patients needed operations year after year. Accelerated approval rests on fewer surgeries, an in-between measure; Inovio must run follow-up trials to confirm the benefit. Most trial patients still needed some surgery. Common side effects included injection-site reactions, headache, tiredness and high blood pressure.

FDA approves Voceryq, the first plasmid-DNA immunotherapy in the US, to cut repeat airway surgeries. Like handing a building's security guards a wanted poster: the DNA makes the body's cells show the virus's 'face', so the immune system learns to find infected cells, instead of calling a repair crew again and again to scrape off the damage.
