USB 4 version 2.0 is supposed to transfer 80 GBit/s

The first update of USB 4 should support twice the data rate as before and bring improvements for USB 3.2.

The USB Promoter Group has announced the forthcoming specification of USB 4 Version 2.0 . The biggest innovation is said to be support for data rates of up to 80 Gbit/s over existing USB-C cables and ports. The committee thus doubles the maximum possible transmission rate of the Universal Serial Bus compared to USB 4, which supports a maximum of 40 Gbit/s. The specification for USB-C and USB Power Delivery should be adjusted accordingly.

In addition to the existing passive USB-C cables, the new higher data rate should also be able to be achieved via newly specified active USB-C cables, as the announcement states. In practice, the higher transmission rate is achieved through changes to physical layer 1 in the OSI layer model, which means that changes to the controller will probably be necessary.

Higher transmission rate thanks to new modulation

A few weeks ago, an Intel manager accidentally disclosed the work on 80G Phy Technology, i.e. a new transmission standard with 80 GBit/s. It is now clear that this should be USB 4 version 2.0. It also follows from this how the higher data rate is to be achieved.

pulse amplitude modulation with three states (-1,0,+1), PAM-3 for short, is probably used. Only two states (0,+1) are possible with the Non Return to Zero ( NRZ ) used so far. Two consecutive signals are combined to form a 3-bit data signal for data transmission. PAM-4, on the other hand, uses four symbols, i.e. two bits, which are transmitted per cycle.

If only PAM-3 is used for USB 4 Version 2.0, the clock rate of the transmission compared to USB 4 must also be increased in order to double the data rates. Among other things, PAM-3 is also used for 100 Mbit/s Ethernet (100BASE-T1).

Backwards compatible and protocol updates

The improved transfer rate should also come into play in the other USB specifications. Specifically, the announcement promises, for example, that the tunneling of data in USB 3.2 should be able to exceed the previously possible maximum of 20 Gbit/s. The new standard should also be backward compatible with USB 4 Version 1.0 , USB 3.2, USB 2.0 and Thunderbolt 3.

In addition, the USB standard is to be adapted to the current display port and PCIe standards. This should be Displayport 2.0, which also transmits 80 GBit/s, which can already be possible with a USB-C cable . In addition, there is probably PCI Express 5.0 , which theoretically enables transfer rates of up to 128 GB per second when using 16 lanes. With USB 4 Version 2.0, of course, this cannot be achieved. 

World’s largest offshore wind farm: England less dependent on fossil fuels

The British want to make themselves less dependent on fossil fuels with a new offshore wind farm. The energy is transported on land with 390 kilometer long cables.

The Danish energy company Ørsted has implemented what it says is the world ‘s largest offshore wind farm. This is located around 89 kilometers off the coast of Yorkshire in England and produces more than 1.3 gigawatts of energy.

These come from 165 turbines, which can power more than 1.4 million British homes. The entire park is 463 square kilometers. 81 meter long rotor blades from Siemens are installed in the wind turbines. According to Ørsted, these can power an average British home for 24 hours with just one turn.

Pandemic as a challenge

Patrick Harnett, vice president of the UK program at Ørsted, saw the corona pandemic as a challenge for the project. He said: “This project has been an amazing undertaking. Building the world’s largest offshore wind farm during a global pandemic was a challenge the team overcame with flying colors. I am so proud of how our team worked together to safely deliver this remarkable project. A big thank you to everyone involved who contributed to it.”

The UK could also use the new wind farm to strengthen its energy grid and reduce its dependency on fossil fuels, according to Duncan Clark, UK Region Manager at Ørsted. He says:

“The UK is truly a world leader in offshore wind energy and the completion of Hornsea 2 is a tremendous milestone for the offshore wind industry, not just in the UK but globally. Current global events are underscoring more than ever the importance of pioneering renewable energy projects such as Hornsea 2, which is helping Britain increase the security and resilience of our energy supply and lower costs for consumers by reducing our dependence on expensive fossil fuels. ”

Hornsea 3

With the completion of Hornsea 2, however, Ørsted’s work is not over. Another wind farm called Hornsea 3 is planned to be built in the same area. The company secured a contract with the British government for this at the beginning of the year.

However, Ørsted is not only active in the English North Sea. Last year, the company made a deal with Google to build 83 wind turbines in the North Sea of ​​Lower Saxony .

NASA: SLS And Orion Launch To The Moon On Saturday

NASA has made its decision: On Saturday, a new attempt for the world’s largest rocket to fly to the moon will start. The space agency has made some changes to increase the chances of success.

After a botched start last Monday, NASA is making a new attempt for the Artemis 1 mission . Next Saturday, September 3rd, the “biggest rocket in the world”, SLS (Space Launch System) , will launch.

Initially, the space agency had considered Friday, but the weather forecast speaks against it. There was a 60 percent chance that the weather would result in an aborted takeoff. On Saturday, however, only sporadic rainfall is expected. The launch will be broadcast live on various NASA channels.

Loading procedures are changed

NASA reports that the teams are working on an approach to prevent an error like Monday’s. One of the engines could not be cooled down to -252 degrees Celsius. A hydrogen leak was also discovered.

Now NASA is changing the start procedure: Those responsible now want to complete the tap test 30 to 45 minutes earlier in the countdown process. This would put him in the fast-fill phase with liquid hydrogen. The technicians should practice the new procedure beforehand. NASA has already tested them at the Stennis Space Center in Mississippi.

Check containers and connection points

In addition, NASA is reconfiguring the platforms on the launch pad to give engineers access to the rinsing tank. That’s where the leak had occurred. You should check the affected lines and connection points and tighten them if necessary.

If the launch is successful this time, the SLS will transport its Orion probe the longest distance that has ever been covered by a space capsule. It will also remain in space longer than any other spacecraft used to transport people. This is mainly possible because the capsule transports plastic dummies instead of astronauts .

Investment opportunity lithium: coveted, scarce and expensive

Lithium is an elementary building block for lithium-ion batteries. And as the electric vehicle market expands rapidly, so does the demand for lithium. A development that also offers opportunities for investors.

Electromobility is picking up speed worldwide. Last year, more than 6.5 million electric cars were sold around the world, which corresponds to an increase of 108 percent compared to the previous year.

Around 16.5 million electric cars are now moving from A to B worldwide, which is around three times as many as in 2018. That the market share in the entire automotive market is also increasing sharply – from 4.7 percent in 2020 to 9.5 percent now percent – ​​is therefore not too much of a surprise. A trend that is likely to continue in the future as a result of stricter emission standards and climate change.

The management consultancy Boston Consulting Group expects battery cars to account for around 20 percent of all global sales in 2025 – and by the middle of the next decade it will already be 59 percent. In short: The electric car trend is here to stay.

Persistent supply deficit

In the wake of the rapid growth in electric cars, lithium-ion batteries – and the light metal lithium that goes with them – are also becoming increasingly important. So much so that the already existing supply deficit is likely to increase further.

The official institutes see a supply deficit of up to 200,000 tons of lithium around 2030. Other estimates see a deficit of a similar magnitude or, in some cases, an even greater deficit.

The world market prices for lithium carbonate have been taking this expectation into account for months. While a ton of the “white gold” cost less than 100,000 Chinese yuan (about 14,666 USD) last summer, this price is now around 470,000 yuan. And: Against the background of the probable ongoing supply deficit, the price could still have room for improvement.

Interested investors need to take a closer look

Unlike crude oil, copper or zinc, there are no futures markets for lithium. The world market price is therefore the sum of many supply contracts that have been concluded within the industry and which can sometimes differ greatly depending on the quality of the lithium and the key data of the agreement. That doesn’t make it any easier for interested investors.

Since there are no futures contracts on lithium, derivatives on official prices are no longer used as an investment instrument. However, investors who expect a further price increase can participate indirectly in the price development – ​​for example by taking a closer look at individual companies in the industry. Well-known names include Albemarle from the USA, Allkem from Australia and the Chilean chemical company SQM.

In addition to the big names, there are also numerous smaller companies that claim to want to mine and sometimes process lithium in the future.

One of these companies is the German-Canadian company Rock Tech Lithium. A few weeks ago, the company, which is valued at around 260 million USD, concluded a framework agreement with an undisclosed German car manufacturer and agreed, among other things, to cooperate with a subsidiary of Thyssenkrupp.

Lithium hype: seize opportunities and reduce risks

In the search for returns, however, investors should not be too hastily blinded by supposed success stories and consider that smaller companies in particular without major operational business must first make large investments in order to be able to act on the market.

Many investors have also jumped on the lithium bandwagon in recent months. A diversified engagement and a preference for companies with a transparent supply chain and a sharpened ESG profile could therefore be an important prerequisite for successful investments in the lithium market.

Above all, the lithium extracted from South American salt lakes is considered problematic for reasons of environmental and water protection.

Basically, broadly diversified ETFs score above all because they spread the opportunities and risks over several shoulders. Not only is the choice of lithium ETFs — passively managed funds that invest in companies involved in lithium mining or lithium battery production — not only limited, but these ETFs are often new and relatively new also have a relatively small volume.

Investors who are interested in such an ETF should therefore have a certain willingness to take risks.

Investors who are not exclusively focused on lithium and instead are more interested in companies that cover the entire range of e-mobility can invest in a variety of corresponding ETFs that have a much higher volume and cover significantly more companies. For example, the ETF iShares Electric Vehicles and Driving Technology, which is around three and a half years old, is around 700 million USD and distributes the fund volume to over 100 companies.

Be careful: Despite the promising prospects for the lithium and electromobility market, investors are not guaranteed a nice return.

Disney+ with advertising in December

Disney will launch Disney+ with advertising in December, but you won’t save anything. It will cost $7.99 per month – the same as the current ad-free plan.

Disney has revealed more details about its ad-supported offering, including how much it will cost and when it will be available. Interestingly, this doesn’t make Disney+ any cheaper for existing subscribers.

If you were hoping for an even cheaper version of Disney+ with ads, costing well under $8, that’s not going to happen. Starting December 8, 2022, you’ll be able to watch Disney+ with ads for $7.99 a month. This is the current price for the original ad-free offer. On the day the ad-supported plan launches, Disney will increase to $10.99 per month ad-free in the US. This news shouldn’t come as too much of a surprise, as Disney has been telling investors for months that its flagship streaming service will include advertising, and has never promised any savings.

Still, when the Disney+ advertising schedule rolls out later this year, it will feature “a reduced advertising load and frequency to ensure a great experience for viewers,” Disney CEO Bob Chapek said during the company’s third-quarter earnings call . Disney is reportedly planning to limit commercial breaks to four minutes per hour. The company also confirmed during Wednesday’s conference call that no ads will be running on child profiles.

Disney plans to expand the promotional schedule internationally in 2023. You will only be able to get it on a monthly basis. (Also, the annual subscription for Disney+ without ads will be increased by $30 to $109 per year).
