Denon, Marantz and Yamaha address 4K, 8K and 120Hz gaming issues

Published

on

Last year we started to see the first receivers roll out with HDMI 2.1 ports that could support 120Hz refresh rates and up to 8K resolution. However the early devices have had compatibility issues with other hardware — namely the Xbox Series X — and it looks like the fix will be pretty complicated. 

As Forbes and HD Guru point out, Yamaha, Denon and Marantz all sell receivers that have had these compatibility problems that gamers noticed once the new consoles started rolling out last fall. Denon and Marantz are both brands owned by Sound United, and they’re going to fix it by providing an extra hardware adapter to sit between the Xbox and their receivers. The SPK618 will “correct” the HDMI data from the Xbox so that it’s passed to your 4K/120Hz ready TV while also playing audio. Owners of affected receivers can order the box starting on May 15th by checking with Denon or Marantz.

As for Yamaha, so far it’s advised gamers to connect their consoles directly to the TV — which can have its own issues, as we’ve experienced — and use HDMI eARC functionality to feed audio back to the receiver. It also said “We will address the reported HDMI 2.1 issue via these planned future updates in order to provide customers with the best solution available.”

Hydrogen planes, electric propulsion and new regulations: Aviation is changing 

Published

on

From the Wright brothers’ historic flight in 1903 to the development of supersonic aircraft, the history of aviation has been driven by technology and ambition.

Now, as the 21st century progresses, the sector continues to show its appetite for innovation and radical design.

Last September, for instance, a hydrogen fuel-cell plane capable of carrying passengers took to the skies over England for its maiden flight.

The same month also saw Airbus release details of three hydrogen-fueled concept planes, with the European aerospace giant claiming they could enter service by the year 2035.

More recently, United Airlines announced it had signed a commercial agreement to purchase aircraft from a firm called Boom Supersonic.

In a statement, United said the Overture aircraft — which is yet to be built — was set to be “optimized to run on 100% sustainable aviation fuel.”

All of the above are linked by a focus on technologies designed to reduce aviation’s environmental footprint. This represents a major task, even if the number of flights last year slumped due to the coronavirus pandemic.

According to the International Energy Agency, carbon dioxide emissions from aviation “have risen rapidly over the past two decades,” hitting almost 1 gigatonne in 2019. This, it notes, equates to “about 2.8% of global CO2 emissions from fossil fuel combustion.”

Elsewhere, the World Wildlife Fund describes aviation as “one of the fastest-growing sources of the greenhouse gas emissions driving global climate change.” It adds that air travel is “currently the most carbon intensive activity an individual can make.”

A variety of solutions

Iain Gray is director of aerospace at the U.K.’s Cranfield University. In a phone interview with CNBC, he described zero carbon as “the top priority” for the industry and sought to emphasize the importance of developing a range of solutions to tackle the challenge.

“The really big technology driver is around the propulsion system,” he explained, “but that doesn’t take away from the importance of new technologies around … new lightweight materials, enhanced carbon composite materials, and the systems itself.”

Expanding on his point, Gray provided an example of why the innovations on planes flying above our heads should not be viewed in isolation. 

“There’s a lot of effort goes into reducing the weight on an aeroplane for it only to spend half an hour circling an airport,” he said.

“So the whole interaction of air traffic management with the aircraft itself is a … very important development and new technologies on airspace management are emerging all the time.”

The power of propulsion

Alongside the development of hydrogen fuel-cell planes there’s also been a lot of discussion around electric propulsion in recent years, with firms such as Volocopter and Lilium developing eVTOL, or electric vertical take-off and landing aircraft.

The key with technologies such as these is the types of journeys to which they can be applied.

“If you look at hydrogen fuel cells and you look at batteries, that really is very much aimed at the smaller aircraft, that’s the sub 1,000 kilometer range,” Cranfield’s Iain Gray said.

“You have to do that in a zero carbon way, there’s no question,” he added. “Is that going to make a big difference to the overall CO2 contributions that aviation makes? No.”

“We need to focus on the longer range flights, flights greater than 1,000 kilometers, flights greater than 3,000 kilometers in particular.”

Fueling change

This focus on long-haul trips will be important in the years ahead, even though they make up a small proportion of flights.  

According to a sustainability briefing from Eurocontrol published earlier this year, “some 6% of flights from European airports were long-haul” in 2020, measuring over 4,000 kilometers (around 2,485 miles) in length.

The intergovernmental organization went on to state that “more than half of European aviation’s CO2 emissions were from this tiny proportion of the overall number of flights.”

This viewpoint was echoed by Jo Dardenne, aviation manager at Transport & Environment, a campaign group headquartered in Brussels.

“We shouldn’t forget that the biggest chunk of aviation emissions are linked to long haul flights because you fly longer, you fly higher,” she told CNBC.

“So all in all you’re producing more CO2 … those long haul flights can only be decarbonized by replacing the kerosene that they’re using.”

It’s on these longer journeys that sustainable aviation fuel could have a significant role to play in the future.

Although the European Union Aviation Safety Agency says there’s “not a single internationally agreed definition” of sustainable aviation fuel, the overarching idea is that it can be used to reduce an aircraft’s emissions.

For its part, Airbus describes SAF as being “made from renewable raw material.” It adds that the most common feedstocks are based on crops or used cooking oil and animal fat.

“Currently, the big challenges of sustainable aviation fuel are producing it in the right volumes that are required, and at the right cost point,” Cranfield’s Gray said.

The provenance of feedstocks used for SAF is also important, he explained. “If what you’re doing … to produce sustainable aviation fuel is transporting fuel right across the world using feedstocks from the other side of the planet, then is it really sustainable?”

“The big effort at the moment is looking at how you can produce sustainable aviation fuels in a …  green way.” This could be fuel from waste or local resources, Gray added.

One type of fuel generating interest is e-kerosene, which also goes by the name of synthetic kerosene. According to a briefing from T&E published in February, e-kerosene is produced by combining carbon dioxide and hydrogen.

“What’s great about it is that it can be dropped into these jets without any modification of the engine and of the technology of the plane,” Dardenne said.  

“It’s a carbon neutral fuel, it’s something that can be easily dropped in,” she added. “The only problem is that it’s very expensive.”

Driving cost down will indeed be key in the years ahead, but organizations like T&E are keen to emphasize the potential environmental benefits of using it.

If the CO2 is “captured from the atmosphere” and hydrogen produced using renewables, T&E says “the combustion of e-kerosene will, apart from some residual emissions, be close to CO2 neutral.”

The future

While technology may be developing, the world also needs to come up with rules and regulations focused on the environmental footprint of air travel. 

Examples of these efforts include the Carbon Offsetting and Reduction Scheme for International Aviation and the European Union including carbon dioxide emissions from aviation in its emissions trading system since the year 2012.

In her interview with CNBC, T&E’s Dardenne stressed the importance of “proper regulation.”

She said: “If you price emissions and pollution effectively, then mandate the use of clean technologies, you send the right signals to investors, private and public, to invest in them.” 

“The clearer the regulatory framework the more certainty you can provide to the market that these technologies will have a future,” she added.

“And that will actually bring added value, financial added value, as well as environmental added value.”

Looking at the bigger picture, she went on to state that “proper regulation” would come via effective carbon pricing and fuel mandates, describing the latter as an obligation to use clean fuels. These were, she argued, “the cornerstone of effective aviation decarbonization strategy.”

Jaguar Land Rover said Tuesday it was working on the prototype of a hydrogen fuel cell electric vehicle, with testing of the concept slated to start later this year.

The vehicle will be based on the new version of the company’s Land Rover Defender, and is part of JLR’s broader attempt to meet a target of zero tailpipe emissions by the year 2036. Testing of the vehicle will focus on areas such as fuel consumption and off-road capabilities.

In an announcement, the company — which is owned by Tata Motors — described fuel cell electric vehicles as being “complimentary to battery electric vehicles … on the journey to net zero vehicle emissions.”

“Hydrogen-powered FCEVs provide high energy density and rapid refuelling, and minimal loss of range in low temperatures, making the technology ideal for larger, longer-range vehicles, or those operated in hot or cold environments,” the company added.

As governments attempt to reduce emissions and boost urban air quality, the vehicles people use do look set to change. 

The U.K., for instance, plans to stop the sale of new diesel and gasoline vehicles from 2030. From the year 2035, all new cars and vans will need to have zero tailpipe emissions.

Companies such as JLR are, slowly but surely, attempting to adapt to this new reality. Earlier this year, the firm announced its Jaguar brand would go all-electric from the year 2025. The business also said its Land Rover segment would roll out six “pure electric variants” over the next five years.

Hydrogen’s ‘role to play’

Described by the International Energy Agency as a “versatile energy carrier,” hydrogen has a diverse range of applications and can be deployed in sectors such as industry and transport.

Examples of its use in the transportation sector include hydrogen buses in cities such as London and Aberdeen, while hydrogen fuel cell airplanes have also taken flight in recent years.

Just last week, plans to build a sea-going ferry powered using hydrogen fuel cells advanced after it was announced that a commercial contract for the development of a concept design had been awarded.

“We know hydrogen has a role to play in the future powertrain mix across the whole transport industry, and alongside battery electric vehicles,” Ralph Clague, head of hydrogen and fuel cells for Jaguar Land Rover, said in a statement.

Clague went on to add that it offered “another zero tailpipe emission solution for the specific capabilities and requirements” of JLR’s vehicle line-up.

Jaguar Land Rover is not the only automotive company to look at hydrogen-powered vehicles. Other manufacturers that have dipped into the hydrogen fuel cell market include Toyota and Honda, while smaller firms such as Riversimple are also working on hydrogen powered cars.

Razer’s smart RGB face mask will ship before the end of the year

Published

on

In a few months, you may be able to buy Razer’s Project Hazel — the high-tech face mask with working RGB lights the company unveiled at CES in January. The company has revealed at its E3 2021 presentation that the mask will start shipping in the early fourth quarter this year, which means you could have it in your hands as soon as October. Razer will be selling the mask in batches, though, with each one having limited quantities available for purchase.

The company has also given us an update on the mask design since its debut half a year ago. It will still have replaceable N95 filters and a transparent front cover, but in addition to adjustable face straps for a snug fit, it will also have silicon edges to be able to form a secure seal around your mouth and nose area. The mask will also feature anti-fog coating and interior lighting in addition to the exterior RGB lights, so your face can be visible even in the dark.

Project Hazel was a concept device the accessories-maker showed off at CES until it announced in March that it was going to make the concept a reality. While COVID-19 vaccines are now available, and one could say that Razer is a bit too late, CEO Min-Liang Tan explained that the company thinks people may still want to mask up even with vaccinations as an extra precaution. Further, some countries may not be able to vaccinate their entire population within the next couple of years, which means travelers will have to continue using masks for protection.

Unfortunately, Razer didn’t reveal how much a Project Hazel mask would cost you and if it would ship the device worldwide. It rolled out an Instagram filter that’ll give you a way to see what you’d look like with it, though, in case you want to see first. You can also sign up on the product’s official page to get a notification when it drops.
