A look at Tesla battery degradation and replacement after 400,000 miles
In this new installment of our series on the highest-mileage Tesla Model X (and one of the highest mileage EVs in the world), we look into battery degradation and replacement on a Tesla with over 400,000 miles.
Earlier this year, I bought one of the cheapest and most high-mileage Tesla Model X vehicles ever.
With over 400,000 miles (650,000 km), it’s one of the highest-mileage electric vehicles in the world and serves as a great case study for the longevity of electric cars, in general, and Tesla vehicles in particular.
Fiat Introduces All-Electric E-Ducato Van
FCA’s commercial vehicle arm Fiat Professional presents the production version of its all-electric Ducato van, the Fiat E-Ducato, a year after the first prototype was shown in mid-2019. It will be the first electric Ducato in the 39-year history of the model.
It’s expected to enter the European market within the next few months, starting from selected countries, and will be available in all body variants, offering a payload of up to 1,950 kg and load volume from 10 to 17 m3.
Quantum Dots Shift Sunlight’s Spectrum to Speed Plant Growth
In the consumer electronics industry, quantum dots are used to dramatically improve color reproduction in TV displays. That’s because LCD TV displays, the kind in most of our living rooms, require a backlight. This light is typically made up of white, or white-ish LEDs. The LCD filters the white light into red, green, and blue pixels; their combinations create the colors that appear on the screen.
Before quantum dots, filtering meant that much of the light didn’t make it to the screen. Putting a layer of quantum dots between the LEDs and the LCD, however, changes that equation. QD TVs use blue LEDs as the light source, then take advantage of the quantum effect to shift some of that light to tightly constrained red and green wavelengths. Because only this purified light reaches the filters—instead of the full spectrum that makes up white light—far less is blocked and wasted.
It turns out that this same approach to making your TV picture better can make plants grow faster, because plants, like LCD filters, are tuned to certain colors of light.
Richard Dawkins on scientific truth, outgrowing God and life beyond Earth
Richard Dawkins is one of the world’s most famous atheists. An evolutionary biology at Oxford and best-selling author of The God Delusion — his new book ‘Outgrowing God — A Beginner’s Guide’ aims to inform young people about religion and atheism. He talks to Krishnan about why he wrote it, his passion for scientific truth and whether he thinks there’s life outside of Earth.

Slack’s new integration deal with AWS could also be about tweaking Microsoft
Slack and Amazon announced a big integration late yesterday afternoon. As part of the deal, Slack will use Amazon Chime for its call feature, while reiterating its commitment to use AWS as its preferred cloud provider to run its infrastructure. At the same time, Amazon has agreed to offer Slack as an option for all internal communications.
“Some parts of Amazon had licensed Slack before, but this is the first time it will be offered as an option to all employees,” an Amazon spokesperson told TechCrunch.
Make no mistake, this is a big deal as the SaaS communications tool increases its ties with AWS, but this agreement could also be about slighting Microsoft and its rival Teams product by making a deal with a cloud rival. In the past, Slack CEO Stewart Butterfield has had choice words for Microsoft saying the Redmond technology giant sees his company as an “existential threat.”
ESA moves ahead on low-cost reusable rocket engine
ESA’s Prometheus is the precursor of ultra-low-cost rocket propulsion that is flexible enough to fit a fleet of new launch vehicles for any mission and will be potentially reusable.

Now that they exist it certainly will change the world.
Waste heat is all around you. On a small scale, if your phone or laptop feels warm, that’s because some of the energy powering the device is being transformed into unwanted heat.
On a larger scale, electric grids, such as high power lines, lose over 5% of their energy in the process of transmission. In an electric power industry that generated more than US$400 billion in 2018, that’s a tremendous amount of wasted money.
