The Aggie Bus rolled onto the streets carrying passengers just 16 months after USU demonstrated the first high-power, high-efficiency wireless power transfer system capable of transferring enough energy to quickly charge an electric vehicle. In July 2011, the USU Research Foundation demonstrated 90 percent electrical transfer efficiency of five kilowatts over an air gap of 10 inches. The demonstration validated that electric vehicles can efficiently be charged with wireless technology.

USU’s Wireless Power Transfer team, in cooperation with the Utah Science Technology and Research initiative’s Advanced Transportation Institute at USU, has designed a more efficient way to meet the nation’s transportation needs. By carefully applying a mix of modern advances in engineering and Nikola Tesla’s principles of induction, USU engineer Hunter Wu and his team have solved one of today’s vexing problems in WPT. Their research has led to the development of a robust prototype, which has been fitted to the Aggie Bus. The prototype transfers power over an air gap where no physical contact is required. Wireless power transfer technology delivers a multitude of benefits to consumers that include greater reliability due to no moving parts or cords, added convenience through the elimination of plug-in charging, the assurance of safety by removing the risk of electrocution and aesthetically pleasing devices as a result of no visible wiring.

USU’s Aggie Bus has achieved several significant milestones. It is the first bus developed and designed by a North American organization that is charged with wireless power transfer technology and is the world’s first electric bus with WPT technology combining the three following performance metrics: A power level up to 25 kilowatts, greater than 90 percent efficiency from the power grid to the battery and a maximum misalignment of up to six inches.

“The unveiling of the Aggie Bus today is a historic achievement and a great leap forward in the science and engineering related to electric vehicles,” said Robert T. Behunin, USU vice president of commercialization and regional development. “As a result of the work done by Utah State engineers, scientists and partners, EV owners and operators will now be able to simply drive over a pad in the ground to recharge their batteries, the benefits of which reach far beyond convenience.”

WAVE Inc., a Utah State University spin-out company, worked in cooperation with the USTAR Advanced Transportation Institute to develop the Aggie Bus. WAVE tackles the problem of heavy and expensive electric vehicle batteries through wireless power that transfers electricity between vehicles and the roadway. The Aggie Bus represents a market-ready product that will be used to retire significant technical risk as WAVE moves onto full-scale projects next year. WAVE, in partnership with the Utah Transit Authority, will launch its first commercial demonstration in mid-2013 on the University of Utah’s campus. It will feature a 40-foot transit bus on a public transit route and an increase in wireless power transfer charging from 25 kilowatts to 50 kilowatts. The project has been funded by a $2.7 million TIGGER grant from the Federal Transit Administration and the University of Utah which purchased the bus. WAVE intends to deliver a commercially ready product that operates with the same reliability as current public transit bus options, including diesel and compressed natural gas buses.

“Current battery limitations prevent an all-electric transit bus from operating all day from an overnight charge,” said Wesley Smith, CEO of WAVE. “WAVE solves that problem by charging the bus wirelessly during its daily operations when the bus stops to load and off-load passengers. This technology makes electric buses competitive with their diesel hybrid and CNG counterparts.”

Utah State University has refashioned the way in which it conducts its technology transfer operation. The office of Commercial Enterprises, a division of Commercialization and Regional Development, provides a one-stop-shop for industry partnership and intellectual property development.

The Utah Science Technology and Research initiative is an innovative and far-reaching initiative of the Utah legislature to bolster Utah’s high-tech economy by investing in university research programs and recruiting new, high caliber faculty. Utah State’s wireless power transfer team is a significant part of USU’s USTAR portfolio.

New Physics: Mysterious radiation pointed to the verge of discovering a “ghost” particle that makes up dark matter

Physicists at the Lawrence Berkeley National Laboratory in the United States have found that the mysterious high-energy radiation emitted from the vicinity of a group of neutron stars may indicate the existence of axions – not yet discovered particles within the framework of New Physics, the search for which has been going on since 1977. It is assumed that special types of axions form dark matter. This is reported in an article published in the journal Physical Review Letters. The research is summarized in a press release on Phys.org.

It is believed that axions can form in the core of neutron stars and transform into photons in the presence of a powerful magnetic field. To detect the electromagnetic radiation associated with axions, you need to find stars that do not emit radiation at different wavelengths that can mask the desired signal. 

These objects include the Magnificent Seven neutron stars that emit only X-ray and ultraviolet radiation. They are located at a distance of 200-500 parsecs from the Earth.

The researchers ruled out the scenario that the excess X-rays produced by the Magnificent Seven are actually emitted by other, more distant objects. These sources would be found in datasets from the XMM-Newton and Chandra X-ray space telescopes.

The extra X-rays likely originate from axions hitting an extremely strong electromagnetic field billions of times stronger than the magnetic fields that could be created on Earth, the scientists concluded. The axions themselves resemble neutrinos in their properties, since both have insignificant masses and rarely and weakly interact with matter.

The axion is currently viewed as the most promising candidate for dark matter particles, since another hypothetical candidate, the massive WIMP particle, has gone unnoticed in experiments aimed at detecting it. 

In addition, there may be a whole family of axion-like particles that form dark matter, as suggested by string theory. If axions are found, it will prove that there is a whole new area of ​​physics outside the Standard Model describing the properties of all known particles.

To find out, the next step will be to study white dwarfs, which are not expected to emit X-rays.

“If we see an abundance of X-rays there too, our arguments will be pretty compelling,” said lead author Benjamin Safdie.

The goal of human civilization is to create AI and disappear?

The goal of human civilization is to create AI and disappear? 103

Various sources often talk about civilizations that lived long before us. They all developed, prospered for a while, and then disappeared in an incomprehensible way. 

What is the reason for their decline, we probably will not know. All we can do is admire the remains of stone buildings, over which time has almost no power.

While looking for an answer, we somehow accidentally stumbled upon an interesting saying about the life of Japanese samurai: “A samurai has no goal, but a path.” In the end, the “path of the samurai” ended in what is known – death. The path of any civilization ended in the same way.

If you look at the issue through the prism of a samurai saying, then there is no point in looking for why and how civilization ended its existence. Probably, the process itself and its result are important here. But to whom is it important and what result does it expect?

Mysterious director

Apparently, behind the curtains of this “ancient theater” there is a mysterious “director” who periodically makes necessary adjustments to the history of civilization.

To figure out what’s what, you need to look at current trends in science. Where does a person strive with such an irresistible desire to “play God.” This attracts him and at the same time frightens him, but in no way turns him away from the intended path. Most likely, artificial intelligence (AI) is the purpose of our civilization’s existence.

About 50 years ago it would have seemed nonsense, but to someone, perhaps even now. However, if you trace the last 100 years of the life of our civilization, you get the feeling that most of the discoveries were given to mankind at the same time. A powerful leap has taken place in a hundred years. Why did it happen?

At the beginning of the last century, scientists recognized the existence of fields that have memory and the ability to store and transmit information. It is very likely that such or a similar field can be around the Earth and, more interesting, possess intelligence. Isn’t this the same “Director” hiding behind the screen of the “ancient theater”?

If this is so, then at a certain moment the “Director” gives the selected scientist “access” to certain knowledge (perhaps even in a dream, like Mendeleev), and another scientific breakthrough occurs in the world. Step by step, discovery after discovery, humanity is steadily moving towards the creation of AI. The trend is already well visible.

AI is probably the next “Babylon”, which will combine all the knowledge, culture and accumulated experience of civilization. In the future, the neural network will enter into a connection with the general information field and leave humanity without knowledge, technology, and even a spoken language. This will be the next decline of civilization. And the “Director” will receive another array of new data (experience) in order to start creating a new civilization.

If someone believes that past civilizations ended in large-scale conflicts, then most likely this is already the consequences of “turning off” AI.

llinn, said that the development of artificial intelligence (AI) threatens humanity. According to him, humans face three key threats, but it is AI that should be feared most of all, the expert said. 

Tallinn explained that at the moment, no one can predict what development AI will achieve in the next decades. In addition, the fact that scientists are creating artificial intelligence that can form a new AI without human intervention is also a cause for concern.

In addition, as the co-founder of the popular video calling service noted, the development of synthetic biology also causes concern. According to him, this direction in science allows the creation of artificial DNA sequences and biological systems that may not exist in nature.

Tallinn also drew attention to the fact that he fears we are entering an era of “unknown unknowns”, things that people are not even able to imagine right now.

The renowned German car manufacturer announced a new development. This time, engineers have created a unique robot capable of autonomously charging electric vehicles. 

For more than a year, specialists have been developing this project, but only now the concern was ready to demonstrate the first working prototype. The robot is ready to charge electric vehicles and has shown the high efficiency of this process.

It is called the Mobile Charging Robot, and experts have already compared it to the R2-D2 droid from Star Wars, including squeaks and clangs. Indeed, there is a similarity. Before implementing this idea, the engineers decided that robots should be allowed to charge cars parked in large residential complexes.

This will save their owners from leaving in order to find a gas station. Another advantage is that large parking lots and garages do not have to contain several expensive charging points for electric cars. The car company said in a press release that the robot works exclusively autonomously.

It independently controls and interacts with the vehicle being charged. It opens the cover of the charging socket and independently connects the power plug, then disconnects it. The robot looks like a trailer, which is a mobile energy storage.

It is capable of charging multiple electric vehicles at the same time. Despite the fact that the manufacturer confidently praises its concept, experts saw inefficiency in the fact that first it is necessary to charge the robot’s battery, which is then used to recharge electric cars.

Volkswagen Group Components CEO Thomas Schmall noted that creating an efficient charging infrastructure for the cars of the future is an important step in the company’s development.

Its engineers focus on finding solutions to avoid costly do-it-yourself measures. The mobile robot is only part of the concept that will continue to be developed.
