There are a list of thousands of vehicles that have been tweaked for speed, riveting performance and exhilarating power that’s built and tested to be taken to extremes.
Due to the increasing number of millionaires and their treasured toys, this was definitely a wake up call for the police forces to step their game up and to put a counter measure leverage system into place by upgrading their state vehicles so that they aren’t easily intimidated or outrun by the reckless speedsters on the move. We are to take a look at 10 of the best Police Cars in the world.

Researchers report reversal of current flow in a quantum system
Posted by Saúl Morales Rodriguéz in categories: particle physics, quantum physics
In a classical thermodynamic system, heat current flows from the hotter body to the colder one, or electricity from the higher voltage to the lower one. The same thing happens in quantum systems, but this state can be changed, and the flow of energy and particles can be reversed if a quantum observer is inserted into the system.
This is the main result obtained by the group led by Professor Ángel Rubio of the UPV/EHU and of the Max Planck Institute PMSD, together with collaborators at the BCCMS centre in Bremen. Their study has been published in npj Quantum Materials.
In macroscopic objects such as a current of water, observing the current does not affect the flow of the water and, in accordance with the laws of classical thermodynamics, this flow would take place from the upper to the lower part of the system. However, in quantum systems, “the process of observation changes the state of the system, and this makes it more likely that the current will be made to flow in one direction or another,” says Ángel Rubio, a professor with the Hamburg-based Max Planck Institute for the Structure and Dynamics of Matter.

A single photon reveals quantum entanglement of 16 million atoms
Posted by Saúl Morales Rodriguéz in categories: encryption, quantum physics
Quantum theory predicts that a vast number of atoms can be entangled and intertwined by a very strong quantum relationship, even in a macroscopic structure. Until now, however, experimental evidence has been mostly lacking, although recent advances have shown the entanglement of 2,900 atoms. Scientists at the University of Geneva (UNIGE), Switzerland, recently reengineered their data processing, demonstrating that 16 million atoms were entangled in a one-centimetre crystal. They have published their results in Nature Communications.
The laws of quantum physics allow immediately detecting when emitted signals are intercepted by a third party. This property is crucial for data protection, especially in the encryption industry, which can now guarantee that customers will be aware of any interception of their messages. These signals also need to be able to travel long distances using special relay devices known as quantum repeaters—crystals enriched with rare earth atoms and cooled to 270 degrees below zero (barely three degrees above absolute zero), whose atoms are entangled and unified by a very strong quantum relationship. When a photon penetrates this small crystal block, entanglement is created between the billions of atoms it traverses. This is explicitly predicted by the theory, and it is exactly what happens as the crystal re-emits a single photon without reading the information it has received.
It is relatively easy to entangle two particles: Splitting a photon, for example, generates two entangled photons that have identical properties and behaviours. Florian Fröwis, a researcher in the applied physics group in UNIGE’s science faculty, says, “But it’s impossible to directly observe the process of entanglement between several million atoms since the mass of data you need to collect and analyse is so huge.”

A 100 meter to 150 meter solar array that is attuned to the lithium ion will be about 70% efficient.
JPL is working on the gridded lithium ion arrays to achieve 60,000 ISP.
There is work on 60 meter deployable solar arrays.

Toyota’s Trucks That Only Emit Water Vapor Are Moving Goods in LA
Posted by Ian Hale in categories: energy, transportation
Japanese automaker Toyota is serious about perfecting hydrogen fuel cell technology to power its vehicles, and it’s scheduled an initial feasibility study operations for its zero-emissions heavy-duty truck a little over a week from today. A concept version of a truck running Toyota’s specialized hydrogen fuel cell system designed for heavy-hauling use will be moving goods from select terminals at the Port of LA and Long Beach to nearby warehouses and rail yards beginning on October 23.
“If you see a big-rig driving around the Ports of Los Angeles and Long Beach that seems oddly quiet and quick, do not be alarmed! It’s just the future,” Toyota wrote in a press release. The company expects the daily runs to cover some 322 kilometers (200 miles) to test the fuel cell system’s duty-cycle capabilities. Afterwards, longer trips could be introduced.

A knock off of Boston Dynamics dog robot, but interesting to see. I’d be curious how loud it is, you know it’s usually pretty loud when there’s no audio.

Yes, the Yellowstone volcano can wipe out humanity, but we’ll have years of warning
Posted by Shane Hinshaw in category: futurism
Although some news headlines suggested otherwise, the Yellowstone volcano would give at least years or decades of warning before a cataclysmic eruption.
