How Koenigsegg’s 3-cylinder engine makes 600 horsepower

Posted by in category: engineering

The Koenigsegg Gemera is a four-seat hypercar that can do 0–62 mph in a claimed 1.9 seconds, but perhaps the most remarkable thing about this Swedish rocket ship is its 2.0-liter twin-turbocharged inline-3, which makes a staggering 600 horsepower (plus 443 pound-feet of torque).

Jason Fenske at Engineering Explained has the details on how Koenigsegg extracted so much power from such a small engine. It starts with the cylinders. There may not be many of them, but they are pretty big. They’re actually larger than the cylinders in Koenigsegg’s 5.0-liter V8, Fenske noted.


Koenigsegg’s new Gemera makes over 1700 horsepower, with close to a third of that figure coming from a 3-cylinder engine.

‘Next-Generation’ Total Artificial Heart Successfully Transplanted into First US Patient

Posted by in categories: biotech/medical, materials

Late last year, a French company called Carmat received approval in Europe for its total artificial heart. It’s exactly what it sounds like: a heart made of synthetic and biological materials intended for implantation into people who need heart transplants. Now, just half a year later, the first US patient has received one of the hearts.

The transplant took place last week in a 39-year-old man at Duke University Hospital in North Carolina. The man didn’t go to the hospital expecting to have a heart transplant, but it ended up saving his life.

Multi-day iron-air batteries reach commercialization… at one tenth of the cost of lithium

Posted by in categories: chemistry, energy, sustainability

Boston startup Form Energy has secured $200 million Series D funding for the development of what is being called a breakthrough in energy storage. #solarenergy #solarpv #solar


Solar and wind power have variability in their productive hours, as multi-day weather events can impact output. Therefore, multi-day storage that is cost effective is important in grid reliability.

Boston startup Form Energy developed technology to address this need, revealing recently the chemistry behind their iron-air batteries. The company said its iron-air batteries can deliver renewables-sourced electricity for 100 hours at system costs competitive with conventional power plants. At full-scale production, Form Energy said the modules would deliver electricity at tenth the cost of lithium-ion batteries.

Sirtuins Anti Aging. Revisited. What they are. Why you should care. How you can benefit

Posted by in categories: biotech/medical, life extension, neuroscience

Good day to you all.

Sirtuins are once again, making headlines. From a longer lifespan, again, through to helping old and dormant hair follicles to grow new hair, and of course a discourse between certain personalities on twitter, they continue to stimulate the interest and promise so much…

Perseverance Rover left this in Mars rock trying to get first sample on Red Planet

On July 20th, 2021 NASA’s Perseverance Mars Rover transmitted new images from Red Planet trying to collect first sample. Rover currently studying geological features of “Crater Floor Fractured Rough” area. While the rocks located in this geologic unit are not great time capsules for organics, NASA’s scientists believe they have been around since the formation of Jezero Crater and incredibly valuable to fill gaps in our geologic understanding of this region – things we’ll desperately need to know if we find life once existed on Mars. Photo of tube located in Mars rock was taken by Perseverance Rover on Sol 148.

Extending Human Lifespans: Using Artificial Intelligence To Find Anti-Aging Chemical Compounds

Posted by in categories: chemistry, life extension, robotics/AI

The University of Surrey has built an artificial intelligence (AI) model that identifies chemical compounds that promote healthy aging — paving the way towards pharmaceutical innovations that extend a person’s lifespan.

In a paper published by Nature Communication’s Scientific Reports, a team of chemists from Surrey built a machine learning model based on the information from the DrugAge database to predict whether a compound can extend the life of Caenorhabditis elegans — a translucent worm that shares a similar metabolism to humans. The worm’s shorter lifespan gave the researchers the opportunity to see the impact of the chemical compounds.

The AI singled out three compounds that have an 80 percent chance of increasing the lifespan of elegans:

World’s first 3D-printed steel bridge debuts in Amsterdam’s Red Light District

Posted by in categories: materials, robotics/AI

Amazing.


While Venice may be home to the first 3D-printed concrete footbridge to be constructed entirely sans reinforcement or mortar, the similarly canal laced city of Amsterdam, not to be outdone, has unveiled the world’s first 3D-printed steel pedestrian bridge. The long-awaited project, first announced in 2015, was dedicated on the Oudezijds Achterburgwal canal in the city’s Red Light District on July 15. The ceremony was attended by Her Majesty the Queen of the Netherlands, Máxima, who was assisted by a ribbon-cutting robot during the festivities.

Spanning nearly 40 feet across the canal, the curving 6-ton stainless steel structure was constructed by Amsterdam-based 3D metal printing technology company MX3D using a wire arc additive manufacturing process that marries advanced robotics with welding. With the aid of four robots, the entire printing process took just six months. The completed bridge, designed by Joris Laarman Lab with Arup serving as lead engineer, was first unveiled in October 2018 during Dutch Design Week. Several load-testing rounds followed, the last of which was carried out in the fall of 2019 with plans to install the structure in early 2020. However, ongoing site prep work at the canal delayed the factory-produced bridge’s installation to just last week.

Development of stretchable metallic glass electrodes†

Posted by in categories: electronics, wearables

Stretchable electrodes are essential components for wearable electronics. However, the stretchability of the electrodes is often achieved with the sacrifice of electronic conductivity along with huge variation in resistance. In this work, stretchable metallic glass electrodes (MG-electrodes) that have both h.
