Tesla’s $25,000 “next-generation car” will have a Cybertruck design

Posted by in categories: engineering, sustainability, transportation

The long-promised more affordable Tesla electric car might debut alongside an automated robotaxi.

Tesla is reportedly preparing to build a $25,000 electric car built on the company’s next-generation engineering platform. Axios.

The $25,000 car reportedly has a futuristic design like the long-delayed Cybertruck — the angular pickup truck that Tesla first revealed in 2019. The Cybertruck will supposedly begin production this year, with production-at-scale beginning in 2024.

Posted by in categories: Elon Musk, existential risks, internet, military, satellites, sustainability

New details of Musk’s involvement in the Ukraine-Russia war revealed in his biography.

Elon Musk holds many titles. He is the CEO of Tesla SpaceX and owns the social media company X, which was recently rebranded from Twitter. Going by an excerpt of his biography, published in the Washington Post.

According to the excerpt from Walter Isaacson’s book, Musk disabled his company Starlink’s satellite communication networks, which were being used by the Ukrainian military to attack the Russian naval fleet in Sevastopol, Crimea, sneakily. The Ukrainian army was using Starlink as a guide to target Russian ships and attack them with six small… More.

Membrane-free lithium-ion batteries could help power grid

Posted by in categories: energy, sustainability, transportation

Removing membranes could shave off as much as 30 percent of battery costs since they are the most expensive components.

Researchers at the University of Cincinnati in the US have developed a new design that could make lithium-ion batteries much cheaper to produce. This can have a profound impact on the large-scale energy storage systems needed to store renewable energy, a press release said.

Lithium-ion batteries, extensively used for power electronic devices, have also found their way into electric vehicles (EVs) thanks to their superior energy density over conventional batteries. These can also be deployed to store renewable energy when production is high, but the demand is low.

Zinc bromide batteries get US government help to scale up

Posted by in categories: economics, government, mobile phones, sustainability, transportation

A new facility will be able to produce battery capacity to power 130,000 homes on a daily basis using renewable energy.

Zinc halide batteries touted as a low-cost alternative to battery energy storage system (BESS) have received a significant boost in the US after the Department of Energy (DOE) offered a $400 million loan to help scale production and reduce manufacturing costs, a press release said. The offer will cover setting up of four production lines at battery maker Eos’ facility in Turtle Creek, Pennsylvania.

Lithium-ion batteries are a crucial component of our attempts to switch to a greener economy powered by renewable energy. Although the technology is ubiquitous these days and powers everyday devices like smartphones and even electric vehicles (EVs), it is still very expensive.

MIT’s underwater sensor offers low-power long-range signals

Posted by in categories: climatology, sustainability

The team plans to build battery-free underwater networks.

Deep Sea exploration is about to get more accessible. Researchers at the Massachusetts Institute of Technology (MIT) have developed and demonstrated a technology that can transmit underwater signals spanning kilometers with a relatively low reader transmit power.

The researchers are calling their tech Van Atta Acoustic Backscatter (VAB), which can be used to map the pulse of the ocean. A submerged network of underwater sensors can continuously measure ocean vital signs like the temperature, pressure, and dissolved carbon dioxide to create more accurate climate change models and monitor the efficacy of carbon capture technologies, explained the researchers in their study.

New 3D-printed ‘living material’ could purify water

Posted by in categories: chemistry, nanotechnology, sustainability

Researchers have created a new 3D-printed substance dubbed “engineered living material.”

Removing pollutants from water is a crucial and arduous process to ensure that it is free from harmful contaminants. In recent years, several approaches and technologies for water pollution remediation have been developed and employed, including filtration, nano-materials, and chemical treatment, to mention a few.

PeLEDs offer to make encryption cheaper and more sustainable

Posted by in categories: computing, encryption, quantum physics, sustainability

Perovskite light-emitting diode is used as the light source for a quantum random number generator used in encryption.

Encryption plays an important role in protecting information in this digital era, and a random number generator plays a vital part in this by providing keys that are used to both encrypt and unlock the information at the receiving end.

Now, a team of researchers has made use of light-emitting diodes made from the crystal-like material perovskite to devise a new type of Quantum Random Number Generator (QRNG) that can be used for encryption but also for betting and computer simulations.
