Startup has plans for power plants in sky with drones

first_img(Phys.org) —Here is the idea: flying power plants in the sky as a means of providing clean, renewable energy. Here is more of the idea: this would be a high-altitude aerial power plant that harvests energy from solar, wind and other sources, and beams it wirelessly to the ground. Now the idea gets more interesting: The power plant would be using networks of unmanned drones. The company is New Wave Energy UK, formed in 2012, self-described as “an upcoming energy provider within the UK currently working towards researching and constructing our own novel form of power plant.” (New Wave Energy UK is not associated or affiliated with US-based New Wave Energy Corp.) In the November 15 press release, the company said it was seeking further investment to advance the project. New Wave Energy UK is turning to crowdfunding as one such step. “To raise such equity New Wave Energy UK Ltd are hoping to raise £300,000 through crowd funding on Kickstarter. New Wave Energy UK Ltd also intend to acquire a total of £32 million from private investors during the crucial stages of the project to commercialise the application.” In a November 15 press release, the company announced that “A new and exciting venture into a whole new form of power plant is currently in incubation within the UK.” The company said the “patent pending technology” is a drone-based power plant for combined solar, wind, heat and emerging new forms of energy generation. The technology is to incorporate wireless power transmission from the drones (and their wireless network) to the Earth’s surface,” according to the release.Details about the drone are in a recent Gizmag article on New Wave Energy UK. According to the article, the company’s ambition is for each drone to have four rotors, multiple wind turbines and a flat base for generating solar power. With energy harvested, the devices will power themselves and also 50 kW more that can be transmitted wirelessly to the ground. Rectenna arrays installed inland or on offshore installations would receive electromagnetic waves and convert them into usable power. According to New Wave Energy, “The technology is tailored to operate at 50,000 ft where wind patterns are more reliable, solar production is greater and there is little or no interference from weather patterns.” More information: www.newwaveenergyuk.com/ ;www.newwaveenergyuk.com/upload … se_november_2013.pdf Explore further Citation: Startup has plans for power plants in sky with drones (2013, December 1) retrieved 18 August 2019 from https://phys.org/news/2013-12-startup-power-sky-drones.html NREL calculates emissions and costs of power plant cycling necessary for increased wind and solar © 2013 Phys.org This document is subject to copyright.

Economist suggests humans are still evolving

first_img Increased marrying, and mating, by education level not affecting genetic make-up Citation: Economist suggests humans are still evolving (2016, July 12) retrieved 18 August 2019 from https://phys.org/news/2016-07-economist-humans-evolving.html © 2016 Phys.org Credit: CC0 Public Domain As Beauchamp notes, many in the scientific community have come to believe that humans stopped evolving approximately 40,000 years ago—shortly after the advent of agriculture. But he notes there is also evidence that refutes such claims, such as studies that have shown that people developed an ability to digest milk and to live at high altitudes much more recently. To learn more, he conducted an analysis of records on 20,000 people he obtained from the Health and Retirement Study, which has compiled data on people born between the years 1931 and 1953. He chose this group because the vast majority of them were past child-bearing age—thus he was able to calculate a rLRS for each of them. Besides counting how many children they had, he also looked at body mass index, schizophrenia, age of onset of menstruation and education level—all traits that have genetic roots.After studying the data, Beauchamp found evidence of evolution in two phenotypes—a slight uptick in the age of first menstruation and a trend toward a lower rLRS for people who had more education—conversely, people with less education had more kids and thus more opportunity to pass on their genes.But, as Beauchamp acknowledges, his study was based on a very limited dataset, and it was constricted in that it left out the possible children that might have been born to the people in the database who died before growing old, for example. There is also an issue with the increased age of first menstruation, as recent studies have shown that it is actually going down, not up. And there is evidence that even if evolution is still at work, it appears that it is being overridden by our ability to control so many factors of our lives, such as saving people who would have died a natural death, or artificial fertility measures for educated people who have children later in life. More information: Jonathan P. Beauchamp. Genetic evidence for natural selection in humans in the contemporary United States, Proceedings of the National Academy of Sciences (2016). DOI: 10.1073/pnas.1600398113AbstractRecent findings from molecular genetics now make it possible to test directly for natural selection by analyzing whether genetic variants associated with various phenotypes have been under selection. I leverage these findings to construct polygenic scores that use individuals’ genotypes to predict their body mass index, educational attainment (EA), glucose concentration, height, schizophrenia, total cholesterol, and (in females) age at menarche. I then examine associations between these scores and fitness to test whether natural selection has been occurring. My study sample includes individuals of European ancestry born between 1931 and 1953 who participated in the Health and Retirement Study, a representative study of the US population. My results imply that natural selection has been slowly favoring lower EA in both females and males, and are suggestive that natural selection may have favored a higher age at menarche in females. For EA, my estimates imply a rate of selection of about −1.5 mo of education per generation (which pales in comparison with the increases in EA observed in contemporary times). Although they cannot be projected over more than one generation, my results provide additional evidence that humans are still evolving—albeit slowly, especially compared with the rapid changes that have occurred over the past few generations due to cultural and environmental factors.center_img Journal information: Proceedings of the National Academy of Sciences (Phys.org)—Harvard economist Jonathan Beauchamp has conducted a study of lifetime reproductive success (rLRS) of a small segment of the U.S. population and has concluded that there is evidence that humans are still evolving. In his paper published in Proceedings of the National Academy of Sciences, he describes the study he conducted, his results and why he believes we are still evolving despite our control over our environment.

Why women find dominant men more attractive

first_imgThe findings, published in the journal Human Nature, suggest that men and women with genotypes consistent with prevailing gender norms are seen as more desirable.The researchers from the University of California, Irvine wanted to find out if mate selection could actually be influenced by people’s ability to quickly detect the so-called “good genes.” The team led by Karen Wu turned to speed-dating to test their predictions in a real-life scenario.  Also Read – ‘Playing Jojo was emotionally exhausting’In such meet-ups, participants only had a few minutes to assess the short- and long-term potential of their speed-dating partners, and to decide whether or not to offer their partners a second date.The team recruited 262 single Asian Americans to have three-minute dates with members of the opposite sex. After each speed-date, participants were asked whether or not they wanted to offer their partner a second date, and how desirable they found the person as a romantic partner. Also Read – Leslie doing new comedy special with NetflixParticipants were notified of a “match” (and thus obtained each other’s contact information) only if they both offered each other another date. When examining the DNA samples collected from participants, the researchers focused on two polymorphisms (on two different genes) that were previously linked to social dynamics.One of the polymorphisms is part of the genetic make-up that has been linked to social dominance and leadership. The other, which has been linked to social sensitivity, is part of the opioid receptor gene that contributes to people’s capacity to experience social pleasure and pain, and their need to have social contact.The researchers found that men and women with genotypes consistent with prevailing gender norms were more likely to receive second date offers. They were also seen as more desirable short- and long-term romantic partners.last_img read more

Falakata fiasco Subhanjan Das replaces Nirmal as DM

first_imgKolkata: The state government on Thursday appointed Subhanjan Das as the District Magistrate (DM) of Alipurduar district.

Tricks for good nights sleep

first_imgDo you wake up in the middle of the night and keep staring at the ceiling thinking of ways to finally get some rest before the alarm rings? Are you tired of restless tossing and turning during sleep time? Do you wake up feeling tired in the morning? Try these simple tips to get a perfect good night’s sleep. Listen to bedtime stories, millennial style: Remember those good old days when you enjoyed listening to grandma’s bedtime stories? Not only did her narrations transport you to lands of mystery and utopian countries, but they easily drifted you off to the world of slumber as well. Try the same technique now. Listen to stories or audio books as you tuck in and let your brain relax for a good night’s sleep. There are tons of podcasts and services such as Amazon’s Audible that you can use for this purpose. Also Read – Add new books to your shelf Choose the right mattress: One main reason for your sleepless nights could be your uncomfortable mattress. The best way to address this trouble is to switch to a comfortable mattress that allows you to submerge in deep sleep and wake up in the morning without aches and pains. Look for a mattress that provide complete spine support and are designed keeping ergonomics in mind. Enjoy the compressed relaxation that the memory foam offers.Block all blue light screens before bedtime: It’s imperative to create a calming ambience in your room to get the best quality of sleep. Block all the blue lights emitted from screens of cell phones, computers, tablets, televisions and other gadgets in your bedroom. Also Read – Over 2 hours screen time daily will make your kids impulsiveListen to white noise: Are the sounds of bikes and cars hampering your sleep? The best way to ignore all these external disturbances during sleep time is to listen to white noise. White noise is an ambient noise produced digitally combining different sounds like rustling leaves, rumbling waterfall, etc. White noise works in the background and drowns out other disturbing sounds of traffic, snoring, etc. White noise has the ability to relax you and induce sleep. Worth a try! Drink cherry juice: If you’re struggling with a sleep disorder, then try sipping a glass of cherry juice before you’re off to bed. According to several studies, cherries contain melatonin, a hormone that helps regulate sleep patterns. Isn’t this a ‘sweet’ way to drift off into the land of nods?Do a headstand: Turning the body upside down is not an easy task. However, a headstand will supply enriched oxygenated blood to the brain cells and ward off all depressive thoughts. This exercise if done regularly can beat any kind of sleep disorder. A must try! Place lemons in your room: If you are prone to allergies or suffer from asthma or cold and find it difficult to catch good sleep, then simply cut a lemon and place it next to your bedside table. This will not only leave a fresh citrus scent in your room but will also help you breathe better and sleep well.IANSlast_img read more
