6 Potential Transportation Systems For The Future

6 Potential Transportation Systems For The Future

It is often said that the world has now become a “global village” due to enhanced transportation and communication. Communication technology has made interaction between distant people easy, whereas it is thanks to modern transportation methods that you can now easily travel from one corner of the world to the other corner within a matter of hours.

Primitive transportation systems included just a few animals and wheeled carts. As civilization advanced, we came up with many new vehicles, ranging from trains to motorcars to ships to airplanes; and still our quest for even faster and more reliable transport system continues. In this article, we will be looking at 6 potential transportation systems of the future.

1. Personal Air Vehicle

1

    Generally known as flying cars, PAVs are an emerging aviation market which provide on-demand aviation services. The term ‘PAV’ was initiated by NASA in 2003 when it launched PAVSP (Personal Air Vehicle Sector Project), as part of the Aeronautics Vehicle Systems Program.

    As per NASA, any flying vehicle can be classified as a PAV if it has seat capacity of less than 5 passengers, a speed of 150-200 mph and a range of about 800 miles. Due to several ongoing research projects, a PAV challenge organized by NASA and funding from several organizations, such as the EU, there is great potential that PAVs will one day be deployed into the public market.

    2. Jetpack

    2

      A jetpack is a device that is propelled by jets of emitted gases, which can propel the user into the air/space. The concept of the jetpack arose from science fiction and its history dates back to 1960. It has since been repeatedly featured in literature, movies, video games and research projects and has now become a reality.

      The common fuels for jetpacks are hydrogen peroxide, an oxygen-hydrocarbon mixture, or jet fuel, among others. However, there are many obstacles to the use of jetpacks for transport, like atmospheric friction and our planet’s gravity, low energy density of available fuels and short flight period due to the small size of fuel packs.

      The current prototypes of jetpacks have a small range and height, high fuel consumption and a maximum flight period of only about 10 minutes. Yet, one among the numerous ongoing research projects to enhance the performance of jetpacks might just bring us good news someday, which could make it possible to use them for things like airport transfer.

      3. Backpack Helicopter

        A backpack helicopter is a device that consists of a motor-rotor system, can be worn on a person’s back like a backpack and uses driven-air current to propel the user into the air. The working mechanism of backpack helicopters is the same as in regular helicopters, except that the rotors in backpack helicopters are contra-rotating so as to reduce the turning motion and rotate at a fixed pitch for simplicity, unlike full-scale helicopters.

        They often use a safety harness with a strap to be placed between the legs to prevent the user from falling out of the harness. Some backpack helicopters also provide a seat for the pilot. Besides the portrayal of backpack helicopters in popular culture, many working models of backpack helicopters have already been developed. It might, however, take some time to prepare this transportation system to be launched on a large public scale.

        4. Hover Car

        4

          A hover car is a personal vehicle, pretty much like a car, but which is able to fly at a constant altitude of about a few meters. This new brand of car has been widely portrayed in science fiction and popular culture for a long time, but is now closer to being a reality.

          The theoretical mechanism of a hover car, as described in science fiction, is such that it uses some short-range anti-gravity phenomenon against frictional forces, which enables it to easily hover above the ground and travel at great speed. A hover car doesn’t produce dust cloud, unlike an air-cushion vehicle.

          The closest existing counterparts of hover cars are hovercraft and hover trains. There have been numerous attempts to develop a real hover car since 1958, but so far a hovering altitude of only about few inches has been achieved. Researchers may be close to designing and deploying hover cars that can speed up to 1500 miles per hour in the near future.

          5. Slidewalk

          5

            Contrary to the regular trend of a moving vehicle/user on a stationary track, slidewalk is a conceptual transport system which consists of a moving track that can transport people and objects from one place to another.

            As with many other inventions, the idea of the slidewalk came from science fiction, and has been portrayed in many books, like H.G. Well’s “When the Sleeper Wakes,” Arthur C. Clark’s “The city and the stars” and even in the “The Jetsons” cartoon series.

            Theoretically, slidewalks are structurally strong enough to even support buildings and a large population of travelers, and have an average speed of about 37 miles per hour. Existing examples of transport system similar to slidewalk are conveyor belts, used to transport goods within a production factory, and the “people movers” in some large airports. These examples stand out as a hope that one day we can really bring slidewalks into practice.

            6. Space Elevators

            6

              Space elevators are a proposed system that can be used for space transportation. Russian scientist Konstantin Tsiolkovsky first conceptualized space elevators back in the late 19th century.

              The idea is to anchor a tensile structure (preferably a cable), called a tether, to the planet’s surface, extend it vertically into space/the sky and add a counterweight to it, such that the center of mass for the overall system lies above the geostationary orbit.

              The interaction between outward centrifugal force and downward gravitational force causes the tether to be tense and remain stationary over a single position relative to the planet. Any object (called a climber) can climb up the tether by mechanical means, release the cargo (craft, satellite, etc.) into the geostationary orbit and descend when the job is done. It serves literally as an elevator up into space.

              The challenge is to find a cable material that is both strong and light, such as carbon nano-tubes (CNT). The first construction of boron nitride nanotubes and diamond nanothreads were great breakthroughs in 2014 and have multiplied the chances of the earth’s first space elevator being built.

              10 Best VPNs to Browse the Internet More Securely

              10 Best VPNs to Browse the Internet More Securely

              When it comes to digital security, public Wi-Fi networks aren’t safe enough, making it much easier for hackers to access your personal data. Whether you are studying in a library or scrolling through Facebook in a coffeehouse, it is vital to have a VPN installed on your device.

              VPNs work wonders when it comes to securing your internet connection. By creating an encrypted tunnel between a remote server run by the VPN service, they protect your personal data from prying eyes. There is a variety of VPNs available on the web, and we have collated a list of the best VPNs that stand out from the rest.

              How to Choose a VPN

              • Free trial period – Free trials allow you to try the product risk-free. The same idea technically applies to those with 30-day full refunds as well.
              • Speed – You want your VPN to be just as fast as the internet speed at home. Good quality VPNs are ones where you see little difference between those speeds.
              • Device connection – Of course, the more devices that can connect to VPNs, the better. It increases the customers’ coverage and the product’s value. You also want to consider compatibility since fewer VPNs may work for Mac or Windows only.
              • Number of servers – The number of servers determines how much capacity a VPN can handle while you are connected. The more servers there are, the more users it can handle without running into potential disconnections or slow speeds.
              • Kill switch feature – Having this feature means that your IP address isn’t exposed if the VPN disconnects for some reason. A lack of this feature is a big deal since the whole reason why you’re paying for a VPN is to hide your IP address, among other things.

              Why You Should Trust Us

              Our hand-picked VPNs are incredibly efficient and offer such distinctive features that grant you safe browsing. They outperform many VPNs in terms of both speed and security. Their primary aim is to provide you the utmost security, thus enabling you to surf the web safely and prevent any potential threat from causing harm.

              Among the best VPNs’ many unique features include split tunneling, strict logging policies, high encryption level, and availability of international servers. We have gathered them in this article to enlighten our readers and offer the best pieces of advice before you get one. Therefore, take our word for it, and if you go for a VPN mentioned below, you’d be fully appeased.

              1. NordVPN

              The most popular VPN on the market these days is NordVPN, and it’s easy to see why. It has widespread coverage, offering a selection of over 5,000 servers spanning across 59 countries.[1] Due to the high number of servers, its speed is similar to your Wi-Fi at home.

              Lifehack’s CEO, Leon, has been using NordVPN for many years and wants to recommend it for its remarkable server count in different locations with no-logs policy. The VPN perfectly works with Netflix and Fire TV stick, too.

              NordVPN is also compatible with Mac, Windows, and Linux. You can download the app onto Chrome, Firefox, Android, and Mac OS. Thanks to its massive coverage, it’s easy to connect multiple devices onto these servers.

              In terms of pricing, while NordVPN doesn’t have a free trial period, they argue that their plans are considerably cheaper than those of their competitors. For example, a one-year plan for ExpressVPN costs $8.32 per month, but NordVPN only charges $6.99 monthly.

              NordVPN has a new protocol called NordLynx that is based on WireGuard with speed benefits, though it’s still under development.[2] If you’re looking for general quality and affordability, this is one of the best VPNs around.

              2. ExpressVPN

              ExpressVPN is the second-best option out there for keeping your privacy while browsing the internet. Like many other VPNs here, they will encrypt your IP address, offer vast coverage, and can have multiple devices connected to their servers.

              Compared to NordVPN, while the pricing point is higher, ExpressVPN’s biggest selling point is the number of countries that their connection covers. Depending on where you are in the world, this may be the only option you have. They have fewer servers — 160, to be precise — but they make up for the low server count by covering 94 countries.[3]

              Cost-wise, your best bet is to go with the yearly plan where they charge $8.32 a month. They also have one- and six-month plans.

              3. Surf Shark

              With regards to Surf Shark, you can connect multiple devices to its servers, and it’s compatible with Windows, Linux, and Mac. It is also available on Android, iOS, Chrome, Firefox, and FireTV.

              Furthermore, Surf Shark can whitelist apps and sites, letting them bypass the VPN. This, along with the lines of split-tunneling, is another feature that many VPNs offer. The difference is that Surf Shark allows you to whitelist specific apps or any website, while most VPNs will whitelist all sites or none at all.

              The other consideration for this app is the price. While lower-tier plans are more expensive compared to others, Surf Shark’s 24-month plan is priced at $2.69 a month, so it’s cheaper than even NordVPN’s equivalent plan!

              4. CyberGhost

              Another top-reviewed VPN is CyberGhost. They’ve been around for 15 years and have fine-tuned their offers and features to stay competitive. They provide the standard package of browsing the web and logging into accounts safely and give you access to regionally blocked content.

              The network also maintains security from hackers, malware, and phishing. Aside from that, you can connect multiple devices, and it’s compatible with all kinds of platforms.

              Advertising

              What separates CyberGhost from the others is their extensive coverage. They have multiple servers, and the pricing point is still very low. It covers over 88 countries and has roughly 6200 servers for you to choose from, all while charging $2.75 for their 18-month plan.

              5. IPVanish

              IPVanish’s prime purpose is to give users online freedom by providing fast speeds and private connections. It’s clear that they can meet that promise as they provide many of the features that have been listed previously from their competitors.

              IPVanish is a part of SugarSync now. What is that, you may ask? It’s a cloud-based service that syncs files across devices and computers for sharing, backup, and many more. What this means is that other devices can access various files and videos so long as they are connected to your specific VPN. Furthermore, it can serve as a backup plan if you get hacked or lose your device for some reason.

              Buy this VPN.

              6. Private Internet Access

              Private Internet Access (PIA) is a remarkably generous company in many ways. Aside from the obvious features, they offer great incentives and discounts for people to try out their products. They claim to be the most trustworthy and reliable VPN around, and we believe that.

              One notable thing is that PIA offers a free two-month trial. Compared to other VPNs to this point, none have provided free trials (though all come with a 30-day money-back guarantee). On top of that, small businesses can avail of their VPN at a discounted rate. There is also the fact that their pricing plans go as low as $2.69 a month for two years, and they let you pay with gift cards.

              In terms of specs, PIA has over 2695 servers that cover 47 countries right now.

              These particular aspects make PIA unique and one of the best VPNs to consider.

              7. Hotspot Shield

              Hotspot Shield is all about offering protection while you’re browsing the internet or using streaming services like Netflix. The encryption is military-grade, and its speed is ultra-fast. In truth, it is even marketed as one of the fastest VPNs.

              Hotspot Shield offers a plan that only costs  $7.99 a month; however, it’s one of the few in this list to provide its services for free. Like other Freemium apps, the free version comes with limited features. That said, it gives you a much better feel for the VPN.

              Also, take note that the encryption feature is still there, though the limitations in the free plan include connecting to one location in the US and having limited streaming options and speed.

              Buy this VPN.

              8. TunnelBear

              As unusual as a name choice for an online security protection service can be, TunnelBear is nothing short of incredible. It makes our list of the best VPNs for various reasons.

              The biggest one is that the company goes through a yearly security audit. This is notable because many VPNs don’t bother about independent audits to ensure their systems are secure and safe from any issues. This is critical as VPNs have gotten some bad reputation over the years, as TunnelBear has noted in their post about their security audit.[4] The fact that they are doing this annually ensures that nothing is being compromised.

              Furthermore, TunnelBear offers limited services for free, but even their paid plans are pretty cheap. For individuals, you’re merely paying $3.33 per month. The only catch is that you can connect five devices regardless of which paid plan you pick.

              Buy this VPN.

              9. Norton

              Norton has been on the security scene for some time, and it’s actually one of the founders of the internet security industry. It started with virus and malware protection in 1991 and has since branched off to other sectors as the industry has shifted.

              As you might expect from a company that’s been around for a long time, Norton provides excellent services, and a few of their other services have gone into the VPN package. In reality, Norton is the only one thus far to offer a password manager with their VPN services. They provide 50GB of cloud storage as well.

              Advertising

              Norton has one of the cheapest VPNs, considering you can get their deluxe plan at $49.99 per year. That comes up to roughly $4.17 a month. It might be slightly higher than other equivalent plans, but you get a lot of extra value that makes it worth the price.

              Buy this VPN.

              10. StrongVPN

              The final VPN we want to cover is StrongVPN. Like many others, it’s great at blocking unnecessary web traffic and providing a fast and simple solution to navigating the internet without any hindrance.

              StrongVPN has over 900 servers. It is available in more than 30 countries and compatible with all devices. Beyond that, the only notable selling point it has compared to others is that it also offers Sugarsync services and 250GB of storage, irrespective of your chosen plan.

              As for the pricing, their year-long plan costs $5.83 a month, while their month-long one is $10.

              Buy this VPN.

              Bottom Line

              Getting online protection is important these days, and companies recognize this.

              With more hacks and breaches occurring every single day, the best VPNs can provide an excellent haven for many people who value their security and privacy.

              We hope that by putting together this list, you’ll be able to find the best VPN that you can trust and enjoy using. As you can see, there are several great options with no real wrong one out there. Pick the VPN that’s best for you.
