Mack Electric Garbage Truck

12.05.2019

Garbage trucks clean the city of garbage, but in exchange you have to put up with their exhaust gases and noise. The situation can change the transition to electric traction.

At the recent WasteExpo 2019 exhibition dedicated to waste collection and recycling, Mack (a subsidiary of Volvo) showed an all-electric garbage truck - Mack LR.

The Mack electric garbage truck is equipped with four batteries, the capacity of which is not specified by the company, and a pair of AC motors with a total capacity of 260 kW or 349 hp. With the help of a two-speed gearbox, the moment is transmitted to the rear axles. The brake system of the electric vehicle has a recuperation function, and the charging system supports fast charging.

Mack LR is more than just a demo. As early as next year, tests of the machine in real operating conditions will begin in New York.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

MAX9729 - new headphone amplifier 23.04.2008

Maxim Integrated Products introduced the MAX9729 Highly Integrated ICs, which are headphone amplifiers with patented DirectDrive technology. Built-in software-launched audio boost and volume controls make the MAX9729 ideal for size-critical, high-performance portable applications.

A self-tuning audio input and a 3:1 stereo input multiplexer also help reduce system size and cost. In addition, the MAX9729 uses the latest crackle and noise reduction circuitry from Maxim Integrated Products, which eliminates audible noise during power supply on and off. The audio frequency response boost circuitry improves playback quality when using inexpensive headphones.

The built-in volume control circuit has 32 discrete levels of control and uses a smoothing function to ensure smooth volume changes when turning off and selecting an input. Eight different maximum gain programming modes allow you to play input signals over a wide range of levels.
