The noise barriers built in Switzerland can supply up to 101 gigawatt hours of solar electricity every year. The prerequisite is that all noise barriers are covered with solar installations, as far as this is possible and economical. This would be possible with a solar capacity of 111 megawatts. This is the result of a study commissioned by the Swiss Federal Council at the instigation of Bruno Storni, a member of parliament from the Swiss Social Democratic Party.

This potential is far below what is technically feasible. However, the authors of the study subtracted the potential that would hardly be economically feasible according to the current state of the art. In addition, they had to take into account site conditions such as shading of the walls or safety aspects.

101 gigawatt hours sounds a lot. But this is only 0.15 per cent of the usable solar potential on roofs and facades used for comparison in Switzerland. For the federal road administration Astra and the Swiss Federal Railways (SBB), however, it is nevertheless a major step towards climate neutrality. After all, solar installations on noise barriers near road tunnels alone cover eleven per cent of the potential on Astra’s total surfaces.

Cutting the price of CO2 removal to under $100 per ton.

Reducing global carbon emissions can go a long way in reducing the impact of climate change, though it may not be enough.

In a bid to turn the tide around amid dire scientific predictions, the U.S. Department of Energy (DOE) announced ambitious new plans to accelerate the development of carbon capture technologies, a report from The Verge explains.

Dr. Yuval Noah Harari, macro-historian, Professor, best-selling author of “Sapiens” and “Homo Deus,” and one of the world’s most innovative and exciting thinkers, has a few hypotheses of his own on the future of humanity.

He examines what might happen to the world when old myths are coupled with new godlike technologies, such as artificial intelligence and genetic engineering.

Harari tackles into today’s most urgent issues as we move into the uncharted territory of the future.

According to Harari, we are probably one of the last generation of homo sapiens. Within a century earth will be dominated from entities that are not even human, intelligent species that are barely biological. Harari suggests the possibility that humans are algorithms, and as such Homo sapiens may not be dominant in a universe where big data becomes a paradigm.
Robots and AI will most likely replace us in our jobs once they become intelligent enough.

Although he is hopeful that AI might help us solve many problems, such as healthcare, climate change, poverty, overpopulation etc, he cautions about the possibility of an AI arms race.

Furthermore Dr. Yuval Noah Harari suggests this technology will also allow us to upgrade our brains and nervous systems. For example, humans will be able to connect their minds directly to the internet via brain implants.

The dramatic rise of online learning during the COVID-19 pandemic has spotlit concerns about the role of technology in exam surveillance — and also in student cheating.

Some universities have reported more cheating during the pandemic, and such concerns are unfolding in a climate where technologies that allow for the automation of writing continue to improve.

Over the past two years, the ability of artificial intelligence to generate writing has leapt forward significantly, particularly with the development of what’s known as the language generator GPT-3. With this, companies such as Google, Microsoft, and NVIDIA can now produce “human-like” text.

Today (Nov. 5), Space Chat will explore what’s new in space, including new climate science, SpaceX’s new astronaut launch and a seriously powerful solar storm.

Every Friday at 1 p.m. EDT (1800 GMT), Chelsea Gohd hosts Space Chat, which you can find live on Space.com’s VideoFromSpace YouTube, Facebook and Twitter pages. Every week, the series explores a new space-tastic topic, spanning from Earth to the universe and far, far beyond.

ZipCharge has launched a new type of charging product for EVs that might be able to convince people worried about range anxiety to switch from gas vehicles. The British startup has introduced a powerbank for EVs called ZipCharge Go at the Cop26 climate summit. It’s about the size of a suitcase and weighs around 50 pounds — plus, it has wheels and a retractable handle, so users can put it in their trunk and easily take it out when they need to charge.

According to the company, the Go can provide up 20 miles of range after being plugged into the car for 30 minutes. A higher capacity version will be able to provide an EV up to 40 miles of range. The device works with any plug-in hybrid or EV with a Type 2 socket, and it can charge that vehicle to its full capacity between 30 minutes to an hour. Charging up the device itself is as easy as plugging it into any socket, and users will be able to control and monitor it through an app, where they can schedule future charges during off-peak hours for cheaper costs.

While range anxiety is becoming less of an issue these days, it’s still keeping those on the fence from making the leap. A company called Gogoro developed hot-swappable battery technology for scooters to address the problem, but batteries in electric cars typically can’t be swapped out. SparkCharge has a portable EV charging system called the Roadie, but it’s not nearly as easy to carry around as the Go.

The world wants to “transition” away from fossil fuels toward green energy, but the difficult reality is this: Dirty fuels are not going away — or even declining — anytime soon.

The total amount of renewable energy that’s available is growing. That’s good news for a world threatened by potentially devastating climate change.

But the increase in renewable energy is still lower than the increase in global energy demand overall. A “transition” from fossil fuels may come someday, but for now, renewable energy isn’t even keeping pace with rising energy demand — so fossil fuel demand is still growing.

Evolutionary genomics approach identifies genes that enable plants to live in the Atacama Desert, offering clues for engineering more resilient crops to face climate change.

An international team of researchers has identified genes associated with plant survival in one of the harshest environments on Earth: the Atacama Desert in Chile. Their findings, published in Proceedings of the National Academy of Sciences (PNAS), may help scientists breed resilient crops that can thrive in increasingly drier climates.

“In an era of accelerated climate change, it is critical to uncover the genetic basis to improve crop production and resilience under dry and nutrient-poor conditions,” said Gloria Coruzzi, Carroll & Milton Petrie Professor in the New York University (NYU) Department of Biology and Center for Genomics and Systems Biology, who co-led the study with Rodrigo Gutiérrez.
