Company claims it has tripled the power of electric engines

EU investigates private key leak in forged COVID passports, the closest alien world to our solar system might have oceans like earth. Oct 30, 2021 # Greetings! Only 4 light-years away, there's an alien world, and scientists think it may have oceans as big as our pale blue dot's. How cute! Moving on to aeronautics, you might have figured that while the electric vehicle market has exploded in recent years, the transition to electrified aviation has been less eventful. Now, a Colorado-based company thinks they can change this by tripling the power of electric engines. And apart from all these, the EU would really like to know, how Mickey Mouse, Adolf Hitler, and Sponge Bob all got valid EU COVID-19 passports used by EU citizens to travel across national borders. This is The Blueprint. Keep going. INNOVATION [A Colorado Firm Claims It Can Triple the Power of Electric Engines]( [Electric Engine]( While the electric vehicle market has exploded in recent years, the transition to electrified aviation has been less eventful. While drone-based flight has been around for a while, even going commercial in many places, larger flights have been constrained by the electric technologies available and the sheer size of commercial aircraft. Energy densities of lithium-ion batteries haven't reached the threshold where long-range flights can be undertaken. But, [that may soon change]( A Colorado-based called startup called H3X is looking for ways to improve electric motors and their power capacity. Who is H3X? The company consists of three university buddies. Jason Sylvestre, Max Liben, and Eric Maciolek first formed a bond as they participated in an engineering course regarding electric vehicles. After their careers led them in separate directions, with each finding work in the [tech and auto industries]( a Department of Energy grant brought them back together to ponder how they could improve electric motors. What have they invented? Their first-principles mindset and efforts have borne fruit in the form of a new electric motor that can potentially power large commercial flights. The team started from scratch, looking at the various components of the electric motor. Comprised of a gearbox, a power delivery system, and a main motor, these components are usually housed separately to allow sufficient cooling space, without which could result in engine failure. However, coupling advances in material science and electronics with the ability to 3D-print materials like copper, the team managed to put all components together into a single housing that weighs just 33 pounds (15 kg) without impacting their cooling needs. Their motor, called the HPDM-250, is much smaller than their contemporaries and has less mass as well. How powerful is their new motor? The [propulsion system of a commercial aircraft]( such as Boeing 737 must deliver a continuous power density of 12 kW/kg. However, conventional electric motors can only generate a maximum of up to 4kW/kg. Thanks to its reduced weight, the company claims that the HPDM-250's power density clocks up to an impressive 13kW/kg.

[The EU would really like to know]( and is now investigating the leak of the digital private key used to validate and certify COVID-19 vaccinations, negative tests, or successful recovery from the disease. Digital passports, also known as "Green Passes" are used in the EU when crossing borders and serve also as a contact tracing tool. Although, someone apparently leaked the private digital key used to validate passes, allowing anyone with the key to forge a Green Pass. On Twitter, white-hat hacker reversebrain was the first to bat an eye about the leaked key, showing a valid pass issued for Adolf Hitler. Shortly after, it lost its legitimacy, likely due to authorities revoking the leaked key. Going for as much (or as little) as $300, there has been an online market for forged passports. An EU spokesperson told BleepingComputer "We are aware of alleged fraudulent manipulations of EU Covid Certificate QR code and have seen the reports," The spokesperson remarked that they're following this incident closely with the relevant member states and that the [investigations and remediations are underway](.

The researchers found that a planet located in the Alpha Centauri system's habitable zone probably has "a reduced (primitive) mantle that is similarly dominated by silicates albeit enriched in carbon bearing species", like the graphite and diamond on Earth. Furthermore, planets orbiting the Alpha Centauri system at a safe distance from their host stars are also [likely to house an iron core]( slightly larger than Earth's, and roughly the same water capacity. How did we discover them? The lead author of the study Haiyang S. Wang, who is also a postdoctoral researcher in the Exoplanets Habitability Group at ETH Zurich, worked with several other scientists to use a model that studies the composition of rocky planets indirectly, by analyzing the conditions of their host star. This method was applied to the nearest sun-like stars — Alpha Centauri A and B — to estimate the bulk composition of any rocky, Earth-like planets positioned in the habitable zone of Alpha Centauri. Additional modeling from there further revealed what the interiors and early atmospheres of these planets might look like. Can we populate them? Don't pack your bags just yet! According to the study, planets in the Alpha Centauri system probably have an atmosphere [much like Earth's early days]( in an era called "Archean Earth," roughly 4,000 to 2,500 million years ago. While there was liquid water at this stage on Earth, it may have been highly acidic, and the atmosphere was sorely lacking in free oxygen.

We asked if life would be better on Mars if space baron billionaires like Elon Musk, Jeff Bezos, and Richard Branson successfully colonized it. 42% percent of you were wary of it and went for "Big tech with even less regulation? Count me out." 26% of you want to go ahead but think we need to do something about the radiation. 16% percent would apparently do whatever it takes to get there. And the final 16% percent, well, you passed, exit the simulation to proceed to the next phase of your training, soldier! Big tech with even less regulation? Count me out. 42% Yes, but only if we protect ourselves from solar radiation. 26% I will literally do anything to go there! 16% Mars isn’t real.

Translated in The Substance of Man (1962), Chap. 7. TODAY IN HISTORY In 1958, the first coronary angiogram was performed, unintentinally, by pediatric cardiologist Dr. F. Mason Sones, Jr. This diagnostic x-ray procedure uses dye injected to visualize blockages of the small nutrient arteries of the heart. While intending to dye a patient's diseased vessels by injecting dye only near their openings, the catheter insertion had inadvertently strayed into the patient's coronary artery, and about 30 cc of the dye went into the artery. Earlier studies on dogs showed the use of the dye in coronary arteries caused heart fibrillation, so it was never tried on humans. Fortunately, the expected heart fibrillation (requiring the opening of the patient's chest to treat) did not occur. Hence the dye could in fact be used safely, especially if in lower amounts.
