Winning Hyperloop design revealed by MIT engineers

Hyperloop – Conceptual Transport System

A team from the Massachusetts Institute of Technology has revealed designs for passenger pods which tend to travel through airless tubes. The Hyperloop is said to be a conceptual transport system wherein passenger of pods could be fired through vacuum tubes at more than 600 mph or 1,000 km/h.

The MIT team first came in a SpaceX competition in designing pods which could be experimented in a prototype tube and would now have the opportunity of building and testing its design in the U.S. Over 115 teams had entered the design competition with the MIT engineers making attempts for the Best Overall Design prize.

At the award ceremony in Texas recently, Mr Musk spoke of the next stage of the competition stating that the basic idea with the competition is that `they were going to try to get the highest possible speed in the 1.5 km track and then you have to stop before the end. There will be foam put towards the end so that one might recover some pieces of the pod. The purpose is to come up with something which could eventually be utilised and if one were to extend the track to hundreds of kilometres, the system would still tend to work

Spur Interest in New Forms of Transportation

What is envisioned to be done with Hyperloop was to spur interest in new forms of transportation’ and Musk is of the belief that it will happen. `It is clear that the public as well as the world would want something new’.

The MIT team beat over 100 other design teams of students from across the world, in order to win the award for the best overall design. The captain of the winning team, Phillippe Kirschen, a master’s student in aeronautics and astronautics commented that `MIT has been involved in so many technological breakthroughs in the past century and it makes sense that we could help advance what might be the future of transportation’, as reported in MIT news.

Chris Merian, chief engineer of the winning MIT team has described the pod as a levitating aluminium capsule and has said that the pod tends to focus on levitating and moving at really high speeds. Those are the two things which are seen as crucial to this being a true Hyperloop pod.As reported by BBC, the pod that tends to function on a custom designed computer system does not have space to accommodate passengers or cargo at the moment

Testing Braking System with Advanced Magnets

But the team has assimilated a fail-safe brake system in order to stop the pod in case its computer system tends to fail to operate. It is said that the MIT team together with 21 other students-led groups had the opportunity to graduate to the next level and experiment their designs on SpaceX’s mile-long test track.

The team is said to now concentrate on testing out its braking system using advanced magnets to plunge their pod at a speed of 100m per second. By mid-May, the final assembly of the design would be preferably ready for testing.

Envisioned concept of a `fifth mode of transportation’ the Hyperloop was announced by Elon Musk, the entrepreneur and tech titan in August 2013. The concept involved high speed transportation of cargo and passengers aboard a `pod’ which would travel within airless tubes.

 Though SpaceX had mentioned that it had no plans of commercialising Hyperloop, it however prefers to quicken the progress. Presently the tech company is said to be developing a mile long track in California that will be utilised in experimenting several pod designs in the forthcoming months.

Next-Gen Incandescent Bulb is a Light-Recycling Marvel

New Incandescent Light Bulb – More Efficient than LED

A new incandescent light bulb has been invented by a team of researchers at the Massachusetts Institute of Technology due to the breakthrough in nanotechnology which tends to be much more efficient than LEDs. The US researchers state that they have developed the technique which could considerably advance the efficiency of the traditional incandescent light bulb.

The older bulbs have been phased out in several countries since they tend to waste large amount of energy as heat. However the scientists at MIT have discovered means of recycling the waste energy and aiming to get back on the filament where it is re-produced as visible light. They are of the belief that they have developed the skill which could turn the weakness of the traditional incandescent bulb into power.

 The incandescent light bulb is a wonderful world changing invention. Its form is iconic with the light it tends to produce is matchless. The MIT team comprising of professors Marin Soljacic, John Joannopoulos and Gang Chen, have not necessarily re-invented the incandescent bulb nor have they done away with LEDs and CFLs, ushering in new era of incandescent. They have set out in solving an old problem by utilising new technology.

Two Stage Light Recycling Process

Significant to the technology on display with the next gen incandescent, is a two stage light recycling process wherein infrared radiation which is produced by conventional tungsten filaments is taken by photonic crystals based filter wrapped around the filaments. Performing as nano-mirror, the crystals made of Earth-abundant materials tend to reflect the energy back to the filament so that the radiation instead of being wasted as heat is reabsorbed and harvested producing visible light.

The discovery disclosed in the journal Nature Nanotechnology is undoubtedly impressive if a touch puzzling to those of us who do not tend to dedicate time and energy to nanophotonics. It could be simple just to think of these incandescent as self-recycling bulbs which could connect a source of waste and then transform it into a source of energy.

Applying this technology of light-recycling to commercial lighting could be a small part of a intricate puzzle as the MIT tend to investigate other application wherein this innovative thermal emission controlling process could be instantly beneficial.

Vast Challenge Faced – Global Warming/Energy Efficiency

But Soljacic had explained to BBC that he `would not exclude the probability of incandescent bulbs re-emerging in a completely more efficient form and it is not totally out of the question considering that incandescent bulbs are not outlawed. The most popular wattages have to be manufactured in order to meet the efficiency standards established in 2007’.

`Thomas Edison had not been the first one to work on the design of the light bulb, however what he had done was to find out how to mass produce it economically and keep it stable for a longer period of over 10 hours and these are the two critical criteria still.

These are questions to which they are trying to answer’. Soljacic further added that they `have a vast challenge which the world is facing presently, global warming and energy efficiency and this give one more tool in the toolbox to meet this challenge and they are excited about the potential’.

Whatsapp Reaches a Billion Monthly Users

WhatsApp – Communication Offering Low Cost Chat

As reported by Facebook, WhatsApp, mobile messaging service is being used by billions of people each month. The app owned by Facebook tends to have overtaken the social network’s own Messenger mobile app that has around 800 million monthly users.

The company has informed that 42 billion messages together with 250 million videos have been sent through WhatsApp on a daily basis. However, one analyst has stated that WhatsApp tends to trail behind local competition in some of the key markets. Jack Kent, mobile analyst at IHS, has commented that there are big markets where WhatsApp is not the leading player.

WeChat in China tends to have over 500 million users while Line is well-known in Japan and Kakao Talk is big in South Korea. However, WhatsApp seems to be certainly most successful, internationally and part of that tends to focus on communication offering low cost chat which is very trustworthy.

While other apps have focused on monetisation, stickers and games,WhatsApp has appealed that it is light on monetisation and has now dropped its annual fee entirely. In 2014, Facebook had bought the mobile messaging app in a deal worth of $19bn.

Secured/Easy Option of Staying Connected

WhatsApp, founded only seven years back has altered the way users seem to message one another and has only one focus which is a secured and easy option for anyone to stay connected with their family and friends all across the globe without the tension of cost etc. that other messaging services tend to burden on their users. Hence whether it is for sharing information during calamity or simply staying connected,

WhatsApp is always available for its users. With their ambitions to grow still further, it would not be surprising to see WhatsApp improve with new features and probably with some enhanced ways of communicating. WhatsApp, not too long ago had planned to drop the $1 yearly subscription fee and since then, WhatsApp had promised not to show ads for their own users’ sake, it leaves one wandering on how the messaging platform intends to make money.

Usage data which the platform tends to generate for Facebook could support the company in improving its targeted advertising that is its fundamental business model according to Mr Kent.

Added Feature – Voice Calling

He has mentioned further that `Facebook had started pushing people to its own standalone Messenger appwhen it had purchased WhatsApp. However, according to him, there was a risk that it could have been attained by a competitor and Facebook could lose millions of highly engaged mobile users to a rival, but WhatsApp still tends to face those challenges from local players who seem to monetise their services well and the same remains to be a competitive space.

In 2015 WhatsApp had up to 700 million monthly users and thereafter WhatsApp has added voice calling wherein users could have another option of getting in touch with their contacts. On addition of the voice calls, it has also decided to develop a web client which reflects the app from the phone and the team tends to continue making improvement with speed and reliability of the app, while ensuring it to be simple and secure.

Samsung Allows Ad-Blocking on New Mobile Web Browser

Android Phone – Install Ad-Blocker Extensions

Latest form of the default web browser on Samsung’s Android phone will now enable users to install ad-blocker extensions that were an update by Apple in September which permits ad-blockers to be installed for the Safari browser as extensions. Samsung phones blockers would have to be added in the same way and would not come as standard. It is said that the new browser would be rolled out for Android Lollipop or advanced users.

Well-known ad-blockers are already available for Samsung phone such as Adblock Fast and Crystal. Besides making web page less messy, mobile ad-blocking is considered to reduce the time of web-page loading as well as mobile data usage wherein the ad-blockers tend to improve the performance of browser by lessening to draw on phone batteries as well as data plans.

`Consumers using ad-blockers would probably use other browsers than the default one’ according to Daniel Knapp, the advertising industry analyst at IHS and `it is nonetheless important for Samsung to jump on the ad-blocking bandwagon. It wants to show customers that it is a premium brand which protects them and Apple’. He also informed BBC that there had been a `seismic change in the ad industry, wherein the marketing budgets had been increasingly moved from traditional forms of advertising, for instance, to sponsorship deals.

Eliminates Scripts in Web-Page Code

He also added that it was the most highly prized by advertisers, young as well as affluent users, who would in the first place, probably use ad-blockers. According to him it is an expression of massive consumer dissatisfaction in the way the ad industry tends to work.

 Ad-blockers tend to work by eliminating scripts in web page code which would then pull content from servers of ad networks. Around 18% of British adults online had been utilising some kind of ad-blocker in November and up 3% from June as per a report from the Internet Advertising Bureau – IAB.

In the meantime, in the annual financial filing of Facebook, the social network had announced advertising earning of $5.64bn for the fourth quarter of 2015 though cautioned that ad-blockers could affect future profits, adversely.It stated that if such technologies tend to continue to thrive especially with regards to mobile platforms, the future financial results could be affected.

Ads Delivered through Third Party Apps

However, Mr Knapp informed that companies like Facebook would be less likely than the other content publishers to get affected by mobile web ad-blockers since ads could be delivered through their third party apps. Thinking of ad-blockers being admitted to iOS 9, they were all completely focused on the in-browser environment and not for third party apps like Facebook.

Samsung had been contacted by Business Insider asking for more information on why the company had released this update. Details are awaited and will be provided on receiving from them. Ad blocking apps had come to the top of App Store charts when the iOS 9 update had been released.

 Though some Wall Street analysts had first feared a worst case scenario, this was Apple against the whole mobile publisher and advertiser ecosystem. Though ad-block apps tend to get lots of downloads, the fraction of users utilising them on regular basis seems to be quite small.

Pilotless Drone to Transport Humans

Autonomous Aerial Vehicle - EHang

One of the transport innovations which had been on display at the CES tech show in Las Vegas was a human-carrying drone. Announced by Chinese company the so-called EHang, the company’s new Autonomous Aerial Vehicle – AAV is a large scale drone which has been designed to separately fly people from one point to another.

The personal minicopter is not operated through manual controls and the passenger can choose a point on a map to travel to a particular place. The device is said to be costing more than $200,000 and could be illegal to ride in public in several countries.Huazhi Hu, CEO of Ehang had started designing the one seater electric drone a couple of years back after two of his pilots had been killed in plane crashes. He had decided that people required a short-to-medium-distance personal air transport where a pilot’s license would not be needed and that took off most of the danger of out of low-altitude flight.

The notion of creating the Chinese built-184 is that users could get to power it and select their destination using a 12-inch touchscreen tablet display and then use the `take-off’ button. The automated flight systems of the drone will then take over from here, handling task like communication with air traffic control together with the other aircrafts, avoid obstacles and navigate.

Safe/Smartest -FailSafe System

It will tend to use the fastest and the safest route between its current place and its destination. Besides being safest, the company has described it as the smartest low altitude autonomous aerial vehicle on the market. The Failsafe system will apparently take control in case of any malfunctions and the passenger would also get the drone to stop and hover in place if required.

If one tends to travel short distance often, this is appropriate option to reduce the strain of traffic and transport through air. One could hop into the only passenger vehicle and go up and away to their choice of destination.

According to EHang, passengers only need to sit back and permit the software and machine to do the work where no piloting or license is needed and flights have now become very easy. EHang also envisages the 184 for shipping medical transport and much more.

Eight Propellers/Four Arms

The craft comprises of eight propellers together with four arms which is created with reinforcements in place should a component tend to fail. EHang has also mentioned that while one is in the air and attacked by a bird, the 184 tends to take suitable action.

Should anyone attempt to hack the 184, the oversized drone is built with encryption which means that one need not worry about someone despicable sending you travelling into a building. The 184 is quite small for an aerial transportation which tends to weight around 440 pounds having a rated load capacity of 220 pounds.

However, the EHang 184 death machine does not seem to be powerful enough to carry across any sort of distance. EHang states that it promises limitless possibilities and would influence the way one tends to travel in profound ways.
