India asks states to consider setting up nuclear power plants, list power utilities

India’s federal power minister on Tuesday asked the states that are away from coal resources to consider setting up nuclear-based power plants, besides identifying and listing the power utilities to meet investments to support growing power demand.

The Indian government in its federal budget this year had proposed to partner with private players to develop small nuclear reactors to increase the amount of electricity from sources that do not produce carbon dioxide emissions.

States should consider setting up nuclear power plants at the sites where coal-based thermal power plants have completed their life, Manohar Lal, the country’s power minister, told states as per a government statement.

India’s stringent nuclear compensation laws have hampered talks with foreign power plant builders such as General Electric GE.N and Westinghouse.

The country, which currently has about 8 gigawatts of nuclear capacity, aims to increase it to 20 GW by 2032.

The minister also asked the states to identify and list their power utilities in the country’s stock exchange to meet increasing investment demand in the power sector as well as improve the transmission system to add more renewable capacity.

India has pledged to achieve a net zero carbon emission target by 2070 and has a target of 500 GW of renewable energy by 2030.

Why a power struggle has broken out over Kirkuk

Watch Video | Listen to the Audio

JUDY WOODRUFF: Longstanding rivalries were re-ignited in Iraq today between vital American allies.

Iraqi military forces and militia moved to push Kurdish forces out of the disputed city of Kirkuk in the country’s north.

Lisa Desjardins begins our coverage.

MAN (through interpreter): The commander in chief of the armed forces, Dr. Haider al-Abadi, gave orders to protect the people of Kirkuk and to impose security in the city.

LISA DESJARDINS: After months of simmering tensions, Iraqi federal troops moved to retake the disputed city of Kirkuk from Kurdish forces.

The effort launched before dawn. By midday, Iraqi soldiers, along with state-backed militias, quickly took control of several massive oil fields north of the city. Iraqis also captured Kirkuk’s military airport and various government buildings. They lowered what had been a symbolic Kurdish flag at the governor’s compound.

Journalist Rebecca Collard in Irbil was in Kirkuk this morning.

REBECCA COLLARD, Journalist: You could hear some clashes, some gunfire in the distance, but for the most part, the city seemed more or less abandoned. Now, the Iraqi army, by the end of today, was essentially in control of the whole city and many of the outskirts of Kirkuk.

LISA DESJARDINS: The spokesman for an Iraqi Shiite militia said they achieved all their goals with little resistance.

AHMED AL-ASSADI,  Spokesman for al-Hashed al-Shaabi (through translator): As the troops approached the area, they were confronted by some rebels, who tried to hinder the progress of the advancing units. Our troops returned fire and silenced its source.

LISA DESJARDINS: This comes three weeks after the Kurds held a nonbinding independence referendum that included the disputed province of Kirkuk.

More than 90 percent of the Kurdish region’s residents voted to split from Iraq. The Iraqi federal government, Turkey, Iran and the U.S. all rejected the independence drive.

The multiethnic region of Kirkuk lies just outside of the autonomous Kurdish region in Iraq’s north. Called the country’s oil capital, Kirkuk produces around 500,000 barrels a day.

In 2014, amid the ISIS onslaught across Northern Iraq, the Kurds took control of Kirkuk, as the Iraqi military fled the city. In the three years since, the Kurds, led by their president, Massoud Barzani, sought to cement their hold, despite tensions with the central government.

Today, Kurdish officials accused Iraq of carrying out a major multipronged attack.

MAJ. GEN. AYOUB YUSUF SAID, Peshmerga Commander (through interpreter): I don’t know what is happening exactly, because we have been in this fight since 4:00 in the morning. We have suffered casualties, including martyrs, and now we have withdrawn to this position. Some of the other Kurdish forces have pulled out. They didn’t fire a single shot.

LISA DESJARDINS: While Kurdish forces withdrew from posts south of the city, some residents vowed to die fighting. Thousands of others fled north.

REBECCA COLLARD: For the last few years, the Iraqi forces, these primarily Shia militia, the Hashed Shaabi, and the Kurdish forces have been focused on fighting ISIS. Now that fight is coming to an end, and what the fear is that now these internal division in Iraq are going to become more apparent and possibly more violent.

LISA DESJARDINS: These clashes pit one substantially American-armed military force against another. Both the Kurdish forces and Iraqi government troops are part of the coalition fighting ISIS. The U.S. sought to downplay the fighting, labeling the exchange of gunfire a misunderstanding.

And, in the Rose Garden, President Trump tried to stay neutral.

PRESIDENT DONALD TRUMP: We don’t like the fact that they’re clashing. We’re not taking sides. But we don’t like the fact that they’re clashing.

LISA DESJARDINS: For the PBS NewsHour, I’m Lisa Desjardins.

JUDY WOODRUFF: For more, I’m joined now by Emma Sky. She served as an adviser to General David Petraeus while he was commander of U.S. forces in Iraq from 2007 to 2010, and by Feisal Istrabadi. He’s a former Iraqi ambassador to the United Nations and he helped write Iraq’s interim constitution.

Welcome to both of you.

Let me start with you, Emma Sky.

This has happened so quickly. What exactly has the Iraqi government done?

EMMA SKY, Yale University: The Iraqi government has deployed its forces back up north into Kirkuk.

And since 2003, the Kurds have made it clear that they want to include Kirkuk within their territory in order to proceed with gaining independence, which has always been their goal. But Kirkuk is important to Iraq itself, and no Iraqi prime minister can afford to lose Kirkuk.

So you can see this reaction that has taken place following the referendum on independence, which happened September the 25th, and also included the disputed territories and the city of Kirkuk.

JUDY WOODRUFF: Feisal Istrabadi, what can you add to why the Iraqi government is so set on taking over the city?

FEISAL ISTRABADI, Former Deputy UN Ambassador, Iraq: Well, a couple of reasons.

First, as Emma just said, it is a part of the disputed territories, which are legally and constitutionally under the jurisdiction of the federal government in Baghdad. The KRG expanded into these disputed territories at the time when ISIL was expanding its territory, and then began to take steps to unilaterally declare that these areas were now incorporated into the Kurdistan region, including when it held the referendum that Emma talked about.

It included holding the referendum in these disputed territories. Now, so long as Iraq — so long as we’re talking about a single country, it matters a little less who controls Kirkuk, but once the referendum was held, this gave rise then to the second reason for Baghdad choosing to act now.

As Emma said, Kirkuk is an important oil-producing zone in Iraq. And it is vital for the economic viability of an independent Kurdish state and an important part of the economic viability of the Iraqi state. So there was never going to be a scenario, I think, in which Baghdad would allow a unilateral exercise of control by Kurds to occur over Kirkuk, so long as independence is on the table.

JUDY WOODRUFF: Emma Sky, we heard President Trump say today the U.S. is not taking sides in this.

Is that accurate, that the U.S. isn’t taking sides? What is the U.S. role here?

EMMA SKY: Well, the U.S. has stipulated over and over again that its policy is to support a united Iraq.

So you can see the U.S. has given support to Iraqi security forces, but also to the Kurdish Peshmerga, to fight against ISIS. The U.S. policy for the last few years has really been focused on ISIS and not on the day after ISIS.

But what we’re witnessing at the moment is that different groups are already moving to the day after, which is the power struggle for control of different territories in Iraq.

And Barzani believed that during the fight against ISIS, he became stronger because he got weapons directly from the international community. And, as Feisal said, he was able to extend his control over the disputed territories.

He’s also facing domestic problems within Kurdistan. There are tensions between the different Kurdish groups, and some believe that Barzani has overstayed his term as president.

JUDY WOODRUFF: Which reminds us just how complicated this is, Feisal Istrabadi.

What does the Iraqi central government want here? They’re not going to get rid of the Kurds. What is it that they want?

FEISAL ISTRABADI: Oh, well, I mean, the Kurds of course are a vital part of Iraq. They’re a vital part of the political process, and they have been represented in Baghdad. The president of Iraq is a Kurd and has been since 2005.

I think what needs to occur and I hope what the government of Iraq wants is a negotiated settlement, in which no party dictates terms to the other, but a negotiated settlement.

Look, Irbil has some legitimate agreements with respect to Baghdad. Baghdad has some legitimate agreements with respect to Irbil. I think we need a mediator perhaps or somebody to convene a roundtable — the United States is who I’m thinking of, of course — to address some of those issues.

Most of the issues are, from the Irbil side, economic issues of payments, and from Baghdad’s side, transparency of how much oil Irbil is producing and exporting, which Irbil has never accounted for to Baghdad.

I think if those issues are resolved, perhaps hopefully some of these other issues can at least be delayed for another day. But at the end of the day, neither government — neither the regional government nor the federal government in Baghdad can really tolerate dictation of terms to it by the other side. My hope is that a negotiated settlement obtains.

JUDY WOODRUFF: Emma Sky, where do you see this going from here? Do you see the peace that different sides have worked to hard to create in Iraq unraveling as a result of this?

EMMA SKY: I think there is an opportunity for a deal, and I think the sort of deal that could be negotiated is one that looks at a special status for the city of Kirkuk and negotiated terms for Kurdistan’s separate, whether that be towards confederation or towards independence.

But there needs to be negotiation. There needs to be a look at where should the border between Iraqi Kurdistan and the rest of Iraq actually be, and that requires mediation district by district through those territories.

JUDY WOODRUFF: Well, we know there are other players who are playing an important role here in Iran and Turkey, and this is all very much playing out as we watch, watch it happen in Iraq.

Emma Sky, Feisal Istrabadi, thank you very much.

FEISAL ISTRABADI: Thank you.

EMMA SKY: Thank you.

Xi Jinping celebrates China’s rising power — and his own

Watch Video | Listen to the Audio

HARI SREENIVASAN: President Xi Jinping opened China’s twice-per-decade Communist Party Congress today with a lengthy list of his achievements during his first five-year term, and his vision of where he hopes to take his nation.

But beyond the words, Xi is asserting power like no Chinese leader in decades.

William Brangham reports.

WILLIAM BRANGHAM: The applause, the music, it was a reception befitting the commanding role that Xi Jinping has taken since being named party leader five years ago.

He opened today’s proceedings by hailing reforms he’s put in place, and proclaiming a — quote — “new era for China.”

PRESIDENT XI JINPING, China (through interpreter): The Chinese nation has realized a great leap, from declining in modern history to twisting its fate fundamentally and continuously moving to prosperity.

WILLIAM BRANGHAM: Over 3.5 hours, Xi laid out his vision to shape the nation of 1.4 billion people into what he called a — quote — “great modern socialist country” over the next three decades.

PRESIDENT XI JINPING (through interpreter): Achieving the great rejuvenation of the Chinese nation will be no walk in the park, and it will take more than drumbeating and gong-clanging to get there. The whole party must be prepared to make more arduous, strenuous efforts.

WILLIAM BRANGHAM: Susan Shirk is chair of the 21st Century China Center at the University of California, San Diego.

SUSAN SHIRK, University of California, San Diego: Xi Jinping has a vision of China’s role in the world that is much more ambitious than anything we have seen before, talking about China kind of moving toward the center of the world and having a lot more influence than it did before.

WILLIAM BRANGHAM: In his address, Xi largely ignored the question of political reforms in China, and he didn’t mention President Trump or North Korea’s nuclear weapons program.

But in a rare move, he did acknowledge that with global demand weakening, there were challenges facing China’s export-driven economy.

PRESIDENT XI JINPING (through interpreter):  While China’s overall productive forces have significantly improved and in many areas our production capacity leads the world, the more prominent problem is that our development is unbalanced and inadequate.

WILLIAM BRANGHAM: Xi was one of the first foreign leaders to meet with President Trump.

PRESIDENT DONALD TRUMP: The relationship developed by President Xi and myself, I think, is outstanding.

WILLIAM BRANGHAM: That was decidedly warmer than Mr. Trump’s past criticism of China and its economic and trade policies.

But other U.S. officials are more critical of Beijing’s actions.

REX TILLERSON, Secretary of State: China, while rising alongside India, has done so less responsibly.

WILLIAM BRANGHAM: Secretary of State Rex Tillerson today criticized China’s aggressive displays of economic and military power, particularly its expansion on man-made islands in the South China Sea.

REX TILLERSON: We will not shrink from China’s challenges to the rules-based order, and where China subverts the sovereignty of neighboring countries and disadvantages the U.S. and our friends.

SUSAN SHIRK: I think there are things to worry about in Chinese foreign policy that are mostly related to these maritime sovereignty issues and to a kind of bullying in Asia, but the global ambition could turn out to be positive.

WILLIAM BRANGHAM: Susan Shirk says China has filled a vacuum left by the United States’ withdrawal from global agreements like the Trans-Pacific Partnership and the Paris climate accords.

Perhaps the most important thing to watch for in the next few days is who Xi establishes as his likely successor.

SUSAN SHIRK: That is why there is a lot of speculation now that he may be trying, much like Putin, to stay on beyond his normal term or to rule behind the scenes even after he retires.

WILLIAM BRANGHAM: President Trump will be traveling to Beijing to meet Xi next month.

For the PBS NewsHour, I’m William Brangham.

Sonos Arc Ultra review: New tech powers a big audio upgrade

2024 has been a rough year for Sonos. The company’s would-be triumphant entry into the crowded headphones market was overshadowed by a disastrous app redesign. In the fallout of the botched software update, the company decided to delay products that were ready to be shipped to give itself more time to right the course. Consumer trust eroded, and people who already owned Sonos gear were living in a cycle of constant frustration.

Thanks to a number of rumors, we already knew that one of the pending product releases was the Arc Ultra ($999). A few weeks ago the company decided not to wait any longer to reveal it. While the design is mostly unchanged from the Arc that debuted in 2020, there are several key changes on the inside that make this a better all-in-one solution for people who don’t want to add more speakers to their living room setup. Sonos is promising better bass performance thanks to new speaker tech that’s debuting in the Arc Ultra, but just how good can it be?

The refined design of the original Arc was a massive upgrade from that of the Playbar, and showed a progression from Sonos’ compact Beam soundbar. Honestly, the aesthetic is pretty timeless, in my opinion, and it’s a look that should age well for years to come. That said, it makes sense that Sonos would keep the design for the Arc Ultra, only making some minor changes to the exterior.

The Arc Ultra still comes in both black and white options, allowing you to choose what looks best in your living room or home theater. Sonos updated the controls to mirror what’s available on the newer Era 100 and Era 300 speakers, moving them to a top-facing bar at the back. There’s a volume slider on the right with play/pause and skip controls in the center. On the left side, Sonos gives you a microphone control so you can mute the built-in mics as needed.

And that’s really it in terms of design changes that you can see. The Arc Ultra is slightly shorter height-wise than the Arc, and it’s a little wider than its predecessor. Neither of which make a huge difference, and they won’t drastically change how you position the speaker beneath your TV.

Sonos' new sound motion woofer is situated on the right side of the soundbar
Sonos

Inside, Sonos has re-engineered the Arc Ultra to improve audio performance. The biggest piece of this overhaul is the new Sound Motion woofer that enables better bass performance before you add a standalone wireless sub. The achievement here, thanks to the acquisition of audio company Mayht, is that the new component lays flat, taking up less room than a traditional cone-shaped woofer. The Sound Motion driver also helps deliver increased clarity and depth, on top of doubling the bass output of the original Arc.

Sonos redesigned the entire acoustic architecture of the Arc Ultra during the process of adding the Sound Motion woofer. The soundbar now houses three more drivers than the arc, a list that includes seven tweeters (two of which are upfiring), six mid-range drivers (midwoofers, as Sonos calls them) and the aforementioned woofer for a total of 14. The company also employs 15 Class-D digital amplifiers along with far-field mics for tuning and voice control.

There’s still only a single HDMI (eARC) port, which allows most modern TVs the ability to control the soundbar’s volume and mute options from your TV remote. Moreover, the Arc Ultra is compatible with Wi-Fi 6 and newly-added Bluetooth 5.3 connectivity allows you to stream from any device. And of course, AirPlay 2 is still on the spec sheet. One last thing I’ll mention here is that the Arc Ultra doesn’t ship with an optical adapter if you prefer that connection. The company will sell you one for $25.

Since the Arc Ultra is a Sonos product, there are a lot of core features that are the same as they are on the company’s other devices. You can use the soundbar as part of a multiroom setup and Trueplay tuning is here to adjust the audio to the acoustics of the room. There’s still an adjustable EQ with options for bass, treble and loudness and a Night Sound mode makes things less boomy when someone in your house may be trying to work or sleep.

While Trueplay will give you the best sound customization for the sonic characteristics of your living room, Sonos is enabling a Quick Tune feature for the first time on the Arc Ultra. Here, the soundbar will use its internal mics, as opposed to your phone, to offer a certain degree of improvement. The company says it wanted to give people the option of something quicker than Trueplay, although the full-fledged tuning process doesn’t take very long at all.

Speech Enhancement has been a handy feature on Sonos soundbars for a while, giving you the ability to improve dialog clarity as needed. Before now, it was an all-or-nothing feature, but on the Arc Ultra, the company introduced three levels of speech boost to give you more options to better suit your needs. This means the soundbar can help you hear clearly over background noise or simply follow along better by elevating dialog above the rest of the soundtrack mix.

Sonos moved the controls to a bar along the back
Billy Steele for Engadget

The trademark feature of Sonos’ Ace headphones is the ability to beam the audio from a compatible soundbar to the cans for a private home theater. That TV Audio Swap tool is available on the Arc Ultra, so you can instantly send the sound to the headphones with the press of a button. In fact, Sonos bundles the Arc Ultra and Ace headphones in a $1,373 set. What’s more, the Ace supports spatial audio with dynamic head tracking, so you can count on immersive sound even when you’re employing it on an individual basis.

Despite all of the problems that Sonos has had with its app, some of which it's still working to resolve, I didn't encounter any issues during my testing. The software crashed on me once when the Trueplay tuning process completed, but everything had already run its course and I didn’t have to repeat it. Other than that, the app has worked reliably over the last week while I’ve been putting the Arc Ultra through its paces. Most importantly, the software is stable and the full suite of controls for the new soundbar is available at launch.

The original Arc already sounded great, so Sonos really had its work cut out for it to further improve the audio quality for the Arc Ultra. Thanks to the improved bass of the Sound Motion tech, a change that also takes up less space, the company says it had the ability to then overhaul the mid-range and high-frequency components as well. By using multiple sizes of mid-range drivers and tweeters, Sonos was able to tweak the speaker positioning inside of the soundbar for improved projection and more immersive sound.

In addition to the enhanced bass performance, the second thing that was immediately apparent on the Arc Ultra was those improvements to the dimensional sound. Whether it was a quidditch match in a Harry Potter movie or zooming F1 cars in Drive to Survive, the soundbar now has better directional, immersive sound than its predecessor. Sonos says the Arc Ultra now renders Dolby Atmos content in a 9.1.4-channel setup, versus 5.0.2 with the Arc, which further contributes to the enveloping audio. Interestingly, I haven’t seen any of the competition claim four up-firing channels from the soundbar like Sonos does here (those that do are usually accounting for up-firing drivers in the rear speakers). You can really hear the difference from the second you fire up the Arc Ultra, and the effect is consistent across content sources.

The increased bass performance makes the Arc Ultra a much better speaker for music without a separate subwoofer. You won’t get the bombastic low-end tone the newly updated Sonos Sub 4 can produce, but there’s enough from the soundbar to give Kaytranada’s Timeless, Phantogram’s Memory of a Day and Bilmuri’s American Motor Sports plenty of booming backbone when a track demands it. There’s also still the trademark Sonos clarity I’ve come to expect over the years, which means finer details like the texture of synths, layered guitars and the nuance of acoustic instruments cut through the mix cleanly.

And speaking of clarity, the company’s new Speech Enhancement settings are also a big improvement. Being able to select how much of a boost this feature offered depending on either my needs right then or based on the overall tuning of the content is really nice. It allowed me to max out the dialog when watching movies after my toddler was asleep so that speech didn’t suffer when sound effects were louder during intense scenes of The Hobbit: An Unexpected Journey.

There’s no doubt the Arc Ultra packs in deeper, more immersive sound than its predecessor, but some people will still want a more robust setup to wring every ounce of audio out of a Sonos living room setup. The high-end choice for this is what Sonos calls the Ultimate Immersive Set, which includes the Arc Ultra, two Era 300s and the Sub 4. Right now, that will cost you $2,561. For something less expensive, you can get the Arc Ultra and the new Sub 4 (normally $799) for $1,708 (Premium Entertainment Set). And therein lies the biggest problem with Sonos soundbars: expanding your living room setup to get the most immersive experience gets very pricey very quickly when the centerpiece is already $999.

If you can live without all the conveniences of Sonos products, you can get an all-in-one package from Samsung for $1,500. With the Q990D, you’ll get the soundbar, two rear speakers and a wireless subwoofer in the same box. The setup offers 11.1.4 audio for excellent Atmos sound, thanks in part to up-firing drivers in the rear speakers. Samsung offers a host of handy features, from Q-Symphony audio with TV speakers, SpaceFit Sound Pro room calibration, Adaptive Sound audio enhancement, a dedicated gaming mode and more. The Q990D remains my top pick for the best soundbars for a lot of reasons, a key one being everything you could need comes in one all-inclusive package.

The Arc Ultra is an obvious improvement over the Arc in the sonic department. New technology delivers on its promise to boost bass, clarity and immersive before you start adding extra components. Expanded features like Speech Enhancements and a quick-tune option offer new tools for dialing in the sound, while the stock Sonos experience remains intact. And thankfully, that includes an app that’s more stable than it was a few months ago. The Arc Ultra is still pricey at $999, but it exhibits a lot more sonic prowess than its predecessor for only $100 more.
