Royal BAM announces ‘world’s first’ fully electric road paver and massive 270 kWh batteries

Royal BAM announces ‘world’s first’ fully electric asphalt road paver with dual electric motors and a pair of massive 270 kWh batteries!

Dutch civil engineering company Royal BAM has announced a fully-electric asphalt spreading road paver, which will save more than 93,000 kilograms of CO₂ and 115,000 grams of nitrous oxide emissions compared to its bio-diesel counterparts.

Working together with partners at Wirtgen and New Electric, BAM has replaced the vegetable-oil sourced, bio-diesel powered Volvo Penta Stage V engines with an electric drive, consisting of two “smartly switched electric motors” that pull electrons from a massive 270 kWh battery. For those you keeping score, that’s more than twice as big as the battery used in the 500-mile range Lucid Air electric sedan. (!)

Once the work is done and the road is paved, the Royal BAM machine can power up it’s second 270 kWh battery (!!) and drive itself to the next project, or back to the fleet depot after a long working day.

Structured thermal armor achieves liquid cooling above 1,000°C and solves challenge presented by Leidenfrost effect

A research team led by scientists from City University of Hong Kong (CityU) has recently designed a structured thermal armor (STA) that achieves efficient liquid cooling even over 1,000°C, fundamentally solving a 266-year-old challenge presented by the Leidenfrost effect. This breakthrough can be applied in aero and space engines, as well as improve the safety and reliability of next-generation nuclear reactors.

The research has been led by Professor Wang Zuankai from CityU’s Department of Mechanical Engineering (MNE), Professor David Quéré from the PSL Research University, France, and Professor Yu Jihong, Director of the International Center of Future Science, Jilin University and Senior Fellow of the Hong Kong Institute for Advanced Study at CityU.

The findings were published in the latest issue of the highly prestigious scientific journal Nature.

Single-stage-to-orbit: How the holy grail of spaceflight could soon become reality

It’s the holy grail of spaceflight, and it could come sooner than many expect.

This month, Washington-based Radian Aerospace announced that it’s building a spaceplane that takes off and lands horizontally. The reveal sparked excitement about what could be considered the holy grail of the decades-old industry.

Christie Maddock, a lecturer in mechanical and aerospace engineering at the University of Strathclyde, says that the “alluring concept” has been around for nearly a century.

“The announcement by Radian Aerospace is exciting, mainly in that it means work in this field, towards this goal, is ongoing,” Maddock tells Inverse. “What exactly that work is, and how successful they may be, is impossible to tell without knowing the technical details.”

First-ever electric bus designed and developed in Africa

Nairobi, Kenya - Opibus has just introduced the first all-electric bus in Kenya as well as the first African designed electric bus ever. This is the first major step in the company’s vision to provide a locally designed and developed electric bus that can be mass-produced for the pan-African market, by the end of 2023. This is a step towards realizing Opibus goal of electrifying Africa’s public transport system, deploying products tailored for the local use case. The bus is designed and developed in-house with local engineering talent, while at the same time utilizing local manufacturing partners.

The key to the technology is the Opibus proprietary electric vehicle platform, which is modular and can be the foundation for several types of vehicles. This enables the creation of a bus that is suitable for the African use case, in its reliability, durability and price point. This also means local and global contract manufactures can be used to create a globally competitive product, with a rapid scale-up.

HoloLens Optics Chief Joins Google Amid Reported Push for Upcoming Google AR Headset

Bernard Kress, principal optical architect on Microsoft’s HoloLens team, has left the company to take on the role of Director of XR Engineering at the recently formed Google Labs. A report by The Verge maintains Google is also now gearing up to produce an AR headset that could directly compete with similar offerings from the likes of Apple and Meta.

Before joining Microsoft in 2015, Kress worked as principal optical architect behind Google Glass, the company’s smartglasses that found marked success in the enterprise sector after a rocky reception by consumers in 2013.

At Microsoft, Kress continued his work—principally focused on micro-optics, wafer scale optics, holography and nanophotonics—as partner optical architect on the HoloLens team, overseeing the release of both HoloLens and HoloLens 2.

Engineering plants to talk via bioluminescence

What if plants could tell us when pests are attacking them, or they’re too dry, or they need more fertilizer. One startup is gene engineering farm plants so they can communicate in in fluorescent colors. The result: a farmer’s phone, drone, or even satellite imagery can reveal what is happening in hundreds of acres of fields …

That leads to better food, fewer crop failures, and more revenue for farmers.

In this TechFirst with John Koetsier we meet Shely Aronov, CEO and founder at InnerPlant, and chat about what plants say, and how farmers can understand their messages.

US Airlines Warn of a ‘Catastrophic’ Crisis Caused by New 5G Services

They claim that more than 100,000 passengers could be affected in a single day. 🤔

#engineering

Several high-profile executives of U.S. airlines warned on Monday, January 17, of an oncoming “catastrophic” aviation crisis that will take hold by Wednesday should AT&T and Verizon activate their new 5G services, a report from Reuters reveals.

In a letter obtained by Reuters, the CEOs of several passenger and cargo airlines in the United States, including Delta, United, and Southwest Airlines, warned that signals from the two companies’ new C-Band 5G cell towers could interfere with navigation and safety equipment on their planes.

US airline executives claim the public will be grounded by 5G services

“Unless our major hubs are cleared to fly, the vast majority of the traveling and shipping public will essentially be grounded,” the executives stated in their letter, which was sent to various government organizations, including the Federal Aviation Administration (FAA) and the White House Economic Council. “Immediate intervention is needed to avoid significant operational disruption to air passengers, shippers, supply chain and delivery of needed medical supplies.”

Building a silicon quantum computer chip atom

A University of Melbourne-led team has perfected a technique for embedding single atoms in a silicon wafer one-by-one. Their technology offers the potential to make quantum computers using the same methods that have given us cheap and reliable conventional devices containing billions of transistors.

“We could ‘hear’ the electronic click as each atom dropped into one of 10,000 sites in our prototype device. Our vision is to use this technique to build a very, very large-scale quantum device,” says Professor David Jamieson of The University of Melbourne, lead author of the Advanced Materials paper describing the process.

His co-authors are from UNSW Sydney, Helmholtz-Zentrum Dresden-Rossendorf (HZDR), Leibniz Institute of Surface Engineering (IOM), and RMIT Microscopy and Microanalysis Facility.

Dimming the Sun Could Spell Doom for Humanity, Experts Warn

Policy experts and scientists are coming together to stop such experimentation.

Back in March of 2021, we brought you news of a study from the Bill Gates-backed Harvard University Solar Geoengineering Research Program which aimed to evaluate the efficacy of blocking sunlight from reaching our planet’s surface in order to delay the effects of climate change.

Now, more than 60 policy experts and scientists have come together to claim that these kinds of geoengineering initiatives are very dangerous for humanity, according to Phys.org.

“Solar geoengineering deployment cannot be governed globally in a fair, inclusive and effective manner,” said the researchers in a letter that was further supported by a commentary in the journal WIREs Climate Change.

“We, therefore, call for immediate political action from governments, the United Nations and other actors to prevent the normalization of solar geoengineering as a climate policy option.”

Turns out geoengineering is not all it’s cracked up to be, and experts say that it could be dangerous to play with it.
