Hydrogen dump truck

16.10.2022

Three stories high, fully loaded, the classic mining truck is one of the largest vehicles on the planet. The mining industry contributes up to 7% of global carbon emissions annually. About 50% of this volume is accounted for by dump trucks for transporting heavy rocks.

So Seattle-based First Mode wants to replace its powerful diesel engine with a hydrogen engine. First Mode has created the world's largest mobile hybrid hydrogen power plant, combining hydrogen fuel cells with battery power. It weighs as much as five elephants and is capable of carrying a load equal to the weight of 100 elephants.

In May of this year, the hydrogen hauler made its official debut at the Mogalakwena mine in South Africa, owned by Anglo American. The multinational mining company estimates that the average mining truck in its fleet consumes 900 liters of diesel per year.

Recently, a growing number of industries - from land transport to aviation - are considering hydrogen as an energy source. In August, Germany introduced 14 passenger hydrogen trains. Airbus also announced plans to test hydrogen-powered aircraft in 2026.

Energy research engineer Glenn Rambach notes that hydrogen technology could eventually outperform electric batteries. But building the infrastructure to produce the hydrogen fuel needed to support the truck fleet, he adds, is one of the main challenges facing a project of this magnitude.

Hybrid vehicles running on a combination of hydrogen and electric batteries could alleviate the problem of any mismatch in the electric or hydrogen infrastructure. However, carbon emissions from using hydrogen as a fuel depend on how the hydrogen is produced. "Green" hydrogen is created using renewable energy sources, while "blue" hydrogen is created using fossil fuels.

First Mode says their dump truck was designed to run on green hydrogen and the company is working to build a sustainable supply chain to support the trucks.

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

allergy to money 04.12.2002

Studies conducted by dermatologists from the University of Zurich Hospital (Switzerland) in collaboration with metallurgists have shown that coins of one and two euros, when they are held in a sweaty hand, emit a lot of nickel.

The reason is that the coins are made from two different alloys: the middle is silver and the rim is yellow. In a sweaty palm, such a coin acts like an electric battery, where sweat acts as an electrolyte. The resulting weak electric current drives the nickel ions out. There are more of them than if a person held an ingot of pure nickel in his hand.

Meanwhile, 10 percent of the population is allergic to nickel. The concentration of metal ions on the skin after prolonged contact with coins can be 250 - 300 times higher than the allowable one.

True, dermatologists point out that coins rarely stay in the hand long enough. More dangerous in this regard would be a metal object that is in contact with the skin for a long time, such as a watch.
