Fantastical Thundertruck EV rocks fold-out solar awnings and a snap-on 6WD caboose

Posted by in categories: military, solar power, sustainability

This all-electric 4×4 off-road concept has a monster battery pack, a brutally angular and military look that borrows heavily from the Cybertruck, and pop-out solar panels for off-grid charging. Oh, and if you need extra range, you can snap two extra wheels and a battery onto the back of it with a self-balancing caboose that makes it a six-wheel-drive.

First things first: Thundertruck is the brainchild of a Los Angeles “creative consultancy,” conceived mainly as a way to keep the team busy during the first wave of COVID lockdowns. “Instead of baking bread or making puzzles,” says the Wolfgang L.A. team, “we decided to make a new state-of-the-art EV truck.”

So while Wolfgang says it “has the ability to support an entire product development program, from research and strategy to initial sketches and first prototypes, all the way to advertising launch campaigns and content creation,” it’s fair to say it’s unlikely we’ll be seeing the Thundertruck out bush-bashing or crushing hillclimbs any day soon.

GM delivers its first Hummer EV

Posted by in categories: sustainability, transportation

The next chapter of GM’s electrification strategy is officially underway. The Verge reports GM has started deliveries of the Hummer EV as promised, with its first “supertruck” (an Edition 1) rolling off the line at Factory Zero in Hamtramck, Michigan. The automaker didn’t name the initial customer, but that person clearly paid for bragging rights given the Edition 1’s $110,295 sticker.

You’ll have to wait considerably longer for other trim levels. The $99,995 3X (which drops from 1,000HP to ‘just’ 830HP) doesn’t arrive until fall 2022, while the $89,995 2X variant (625HP) will wait until spring 2023. The $79,995 2 trim doesn’t surface until spring 2024. All but the base version deliver a claimed 300 or more miles of range, while that ‘entry’ model musters 250 miles per charge.

The steep prices won’t leave Tesla, Hyundai and other EV competitors too worried. This is a luxury machine that will sell in limited numbers. However, popularity isn’t entirely the point. This is the first consumer-oriented vehicle to ship using the Ultium battery technology that will underpin numerous GM EVs going forward, including the Cadillac Lyriq and Chevy Silverado. The Hummer is both a halo vehicle for the brand and an answer to challengers like Tesla and Rivian.

MIT Scientists Say Life May Have Been Detected on Venus After All

Posted by in category: space

The hypothesis remains a bit of a stretch: that clouds in the planet’s thick, carbon dioxide-filled atmosphere could harbor lifeforms that also happen to be resistant to the incredibly caustic droplets of sulfuric acid surrounding them.

And indeed, other scientists have also thrown cold water on the hypothesis, calling out the possibility of a processing error that throws the data itself into question.

But now, a new study is giving new life to the tantalizing theory. Sulfuric acid, MIT scientists say, could be neutralized by the presence of ammonia, which astronomers also suspect to be present in the planet’s atmosphere thanks to the Venera 8 and Pioneer Venus probe missions in the 1970s.

The World’s First Robot Manicurist Is Taking Clients

Posted by in categories: augmented reality, drones, robotics/AI

The future imagined in “The Jetsons” is almost here — smart watches track our steps, Zoom connects us to the people we love, and camera drones steadily increase the views on any vlogger’s YouTube channel. The only thing we’re missing from the animated sitcom is air traffic in the form of flying cars. Although, it looks like we’re not too far from that reality, either. Consequently, robots and AR will also be commonplace.

If all of this seems too “Black Mirror” for you to process, we suggest taking a step-by-step approach. Invest in a watch that tells you how much you’ve walked but not how much you’ve slept. Until further notice, only board airplanes to fly. Instead of hiring your own Rosey the Robot housekeeper, meet with a robot every other week.

Tsunamis’ magnetic fields are detectable before sea level change

Posted by in categories: chemistry, physics

A new study finds the magnetic field generated by a tsunami can be detected a few minutes earlier than changes in sea level and could improve warnings of these giant waves.

Tsunamis generate magnetic fields as they move conductive seawater through the Earth’s magnetic field. Researchers previously predicted that the tsunami’s magnetic field would arrive before a change in sea level, but they lacked simultaneous measurements of magnetics and sea level that are necessary to demonstrate the phenomenon.

The new study provides real-world evidence for using tsunamis’ magnetic fields to predict the height of tsunami waves using data from two real events—a 2009 tsunami in Samoa and a 2010 tsunami in Chile—that have both sets of necessary data. The new study was published in AGU’s Journal of Geophysical Research: Solid Earth, which focuses on the physics and chemistry of the solid Earth.

Powerless fridge shows potential of ‘frugal innovation’

Posted by in categories: food, habitats

Though innovation is often associated with Silicon Valley and high-tech start-ups, sometimes all that’s needed to make a big difference in people’s lives is a new spin on tradition, UNCTAD Deputy Secretary-General Isabelle Durant said on 2 July at the opening of a meeting in Geneva on the topic.

Mitticool, the clay refrigerator that requires no electricity, costs less than $50 and can keep food fresh for 2 to 3 days, is just one example of the power of “frugal innovation”, Ms. Durant said.

Inspiration came to the Indian inventor, Mansukhbhai Prajapati, after seeing his community suffer during the Gujarat earthquake of 2001, when a magnitude seven quake wrecked more than 8,000 villages, killing around 20,000 and leaving a million others without a home.

Carbon-air battery as a next-generation energy storage system

Posted by in categories: solar power, sustainability

One of the barriers to generating electricity from wind and solar energy is their intermittent nature. A promising alternative to accommodate the fluctuations in power output during unfavorable environmental conditions are hydrogen storage systems, which use hydrogen produced from water splitting to generate clean electricity. However, these systems suffer from poor efficiency and often need to be large in size to compensate for it. This, in turn, makes for complex thermal management and a lowered energy and power density.

In a study published in Journal of Power Sources, researchers from Tokyo Tech have now proposed an alternative electric energy storage system that utilizes carbon © as an energy source instead of hydrogen. The new system, called a “carbon/air secondary battery (CASB),” consists of a solid-oxide fuel and electrolysis cell (SOFC/ECs) where carbon generated via electrolysis of carbon dioxide (CO2), is oxidized with air to produce energy. The SOFC/ECs can be supplied with compressed liquefied CO2 to make up the energy storage system.

“Similar to a battery, the CASB is charged using the energy generated by the to reduce CO2 to C. During the subsequent discharge phase, the C is oxidized to generate energy,” explains Prof. Manabu Ihara from Tokyo Tech.

Quantum Mechanics and Machine Learning Used To Accurately Predict Chemical Reactions at High Temperatures

Posted by in categories: chemistry, quantum physics, robotics/AI, sustainability

Method combines quantum mechanics with machine learning to accurately predict oxide reactions at high temperatures when no experimental data is available; could be used to design clean carbon-neutral processes for steel production and metal recycling.

Extracting metals from oxides at high temperatures is essential not only for producing metals such as steel but also for recycling. Because current extraction processes are very carbon-intensive, emitting large quantities of greenhouse gases, researchers have been exploring new approaches to developing “greener” processes. This work has been especially challenging to do in the lab because it requires costly reactors. Building and running computer simulations would be an alternative, but currently there is no computational method that can accurately predict oxide reactions at high temperatures when no experimental data is available.

A Columbia Engineering team reports that they have developed a new computation technique that, through combining quantum mechanics and machine learning, can accurately predict the reduction temperature of metal oxides to their base metals. Their approach is computationally as efficient as conventional calculations at zero temperature and, in their tests, more accurate than computationally demanding simulations of temperature effects using quantum chemistry methods. The study, led by Alexander Urban, assistant professor of chemical engineering, was published on December 1, 2021 by Nature Communications.

SolarWinds Hackers Targeting Government and Business Entities Worldwide

Posted by in categories: business, cybercrime/malcode, government

If anything, the development is yet another indication of the threat actor’s capacity to continually “innovate and identify new techniques and tradecraft to maintain persistent access to victim environments, hinder detection, and confuse attribution efforts,” while also highlighting the “effectiveness of leveraging third parties and trusted vendor relationships to carry out nefarious operations.”

Microsoft had previously dubbed Nobelium as “skillful and methodic operators who follow operations security (OpSec) best practices.”

Ever since the SolarWinds incident came to light, the APT group has been connected to a string of attacks aimed at think tanks, businesses, and government entities around the globe, even as an ever-expanding malware toolbox has been put to use with the goal of establishing a foothold in the attacked system and downloading other malicious components.
