It turns out we may all be living in an infinitely large Holo-deck. That’s basically the conclusion a group of researchers reached after analyzing what is thought to be the first-ever observed evidence that the universe could in fact be a gigantic holographic projection . Phys.org reports that a team of theoretical physicists and astrophysicists from the U.K., Canada and Italy made the discovery while researching irregularities in the “cosmic microwave background,” or the “afterglow” of the Big Bang. In the course of that research, which involved using the theory of cosmic inflation, they found substantial evidence to support a holographic explanation of the universe, which actually holds as much weight as the traditional explanations for these irregularities. As Phys.org notes, the idea of a holographic universe first emerged in the 1990s, and involves the theory in which all the information that makes up our 3D reality (including time) is contained in a two-dimensional surface, on its boundaries. Scientists from Canada’s Perimeter Institute and University of Waterloo , the U.K’s University of Southampton and Italy’s University of Salento jointly made this most-recent discovery using advanced telescopes and sensing equipment that can detect data hidden in the microwaves left over from the Big Bang. As Professor of Mathematical Sciences at the University of Southampton, Kostas Skenderis explains: “Imagine that everything you see, feel and hear in three dimensions (and your perception of time) in fact emanates from a flat two-dimensional field. The idea is similar to that of ordinary holograms where a three-dimensional image is encoded in a two-dimensional surface, such as in the hologram on a credit card. However, this time, the entire universe is encoded.” It’s essentially like watching a 3D movie in a theater, when the images appear to have depth, along with width and height, but they are ultimately still coming from a two-dimensional screen. Related: “Largest-ever” new map of universe shows 1.2 million galaxies “Holography is a huge leap forward in the way we think about the structure and creation of the universe.,” adds Skenderis. “Einstein’s theory of general relativity explains almost everything large scale in the universe very well, but starts to unravel when examining its origins and mechanisms at quantum level. Scientists have been working for decades to combine Einstein’s theory of gravity and quantum theory. Some believe the concept of a holographic universe has the potential to reconcile the two. I hope our research takes us another step towards this.” Via Phys.org Images via NASA and University of Southampton

Produce your own water from thin air with SunGlacier’s solar-powered DC03

Comments Off on Produce your own water from thin air with SunGlacier’s solar-powered DC03

If you’re alarmed by reports of dwindling water supplies across the globe, there has never been a better time to take matters into your own hands. SunGlacier founder Ap Verheggen, who has spent the better part of the last decade designing devices that harness the sun’s potential to extract water from thin air, has made his latest design available online – for free. The solar-powered DC03 relies on a Peltier element, explained in greater detail below the jump, to produce a small amount of clean water each day without a battery, without fans or an inverter, and without any moving parts that could easily degrade. The solar-powered DC03 device generates power for an 18W Peltier element. Asked to explain that in layman’s terms, Ap Verheggen told Inhabitat: “A Peltier element is a very small and thin square piece of electronics. If you connect it to electricity, it becomes hot at one side, and cold at the other side. The cold side we use to cool a cone. As the air comes at the cool cone, moisture in the air starts to condensate and produces water drops.” Water drawn from the air then drips, through gravity, into a glass (or whatever vessel each person chooses to use). Because the Peltier element has a temperature difference of 67C maximum between the upper “hot” side and the under “cool” side, according to SunGlacier, the hotter the air, the more water the device produces, bringing the group one step closer to their original ambition of improving water security for people living in desert conditions . Related: A solar-powered leaf that makes ice in the desert At the moment, the device makes about half-a-glass of water every six hours, according to SunGlacier. It is designed to operate during daylight hours only, mitigating the need for a battery. Verheggen says while the DC03 design has been thoroughly tested, it has not been optimized, which is where you come in. In the same spirit as Elon Musk’s approach to the Hyperloop , whereby he encourages anyone to improve upon the original idea, SunGlacier invites the public to take a stab at making their own solar-powered water maker using their design, which is available online . Universities and research institutes from as far afield as Iran, Romania, South-Africa and The Netherlands have already expressed an interest in getting involved, Verheggen says. This collaborative approach is expected to make SunGlacier’s groundbreaking, low-maintenance design accessible to the greatest number of people possible – and that is something we can really get behind. + SunGlacier Photos by Hessel Waalewijn

Tesla just unveiled the world’s largest battery storage plant

Comments Off on Tesla just unveiled the world’s largest battery storage plant

Tesla just completed construction on what it claims is the largest lithium-ion battery storage project in the world. The facility is located at in Ontario, California and it consists of 396 Tesla powerpacks that can store 80 megawatt-hours of electricity – that’s enough to power over 2,500 households for a day or 15,000 households for four hours. Tesla nabbed the contract to build the battery storage facility for Southern California Edison in September 2016, and it was completed by the end of that year. The project consists of two 10 megawatt systems – each made of 198 Tesla Powerpacks and 24 inverters – connected to two different circuits at the Mira Loma Substation. Tesla Chief Technical Officer JB Straubel said “Storage is quite a new thing…and this is a different breed of battery. This is the tip of the iceberg of how much storage we’ll see on the grid .” Related: Solar homes with Tesla’s Powerwall 2.0 are already cost-competitive with the grid in Australia SCE said the facility would allow them to draw more on clean energies like solar power . When clean energy projects produce more electricity than the utility needs, it can now be stores and utilized during peak hours. The Tesla battery storage facility seems like the perfect answer to our energy issues, but MIT Technology Review points out lithium batteries are still expensive, and no one has said how much the facility cost. It’s also not clear how many cycles the Powerpack batteries can go through before they begin to degrade – MIT estimates 5,000 cycles, which would work well in a home but not as well in a grid setting. At the ribbon-cutting, SCE CEO Kevin Payne said, “This project is part of our vision at SCE to take advantage of the wind and the sun, and operate a flexible grid that delivers clean energy to power our homes, our businesses, and our vehicles. Standing here today among these Tesla Powerpacks is a great reminder of how fast technology is changing the electric power industry and the opportunities that will come with it.” Via MIT Technology Review Images via Ernesto Sanchez/Edison International

Comments Off on New quantum theory says universe has ‘no end and no beginning’

Philosophy undergrads aren’t the only ones who get to sit around questioning the origins of our existence. Quantum theorists have a similar job, and they’ve developed a new model  that suggests our universe may not have gotten its start from a ‘Big Bang’ as previously thought. Instead, the model indicates that the universe has no finite beginning; it may also account for dark matter and dark energy, neatly tying up several problems at the same time.
