Hey guys, I made a topic similar to this earlier, but after I was informed that my ideas has several flaws that would prevent it from working, I revised it and researched more about my topic. This is my original idea with several concepts that has changed. I am planning on making a mini-model of this that will test out all concepts, so I would like some critique whether its logic, error in concept, or just difficulty. I am just a simple high school student in a one-year physics course who wants to improve his ability in applied science and using physics to create new things (my dream is to be an inventor) I always had this idea of a Maglev (electromagnetic) hover car where it uses the messier effect and superconductivity for magnetic levitation and Faraday’s electromagnetic induction principal to generate electricity give it the ability to recharge its motor if it runs on newly built magnetic roads. I am a high school junior, a first-year physics high school student, so I don’t know if my physics reasoning is good enough and if I am actually typing in wrong physics concepts on this page right now. So here are my ideas for the maglev car. Main concepts Electromagnetic suspension (Meissner effect) By using a superconductor and using extremely low temperatures, it will allow electromagnetic suspension to be created and give the car the ability to levitate. Possible experiement: Use liquid nitrogen to cool a superconductor/magnet and place it on a magnetic track and see how it levitates and move on the track, basically recreating this experiment: Inductive Coupling/ Resonance This is the use of transferring electrical current from one wire to another with no contact by using induction. This happens when a current flow through a coil and creates a magnetic field in the magnetic rails. The second coil in the maglev car will also create a magnetic field and have the field induce a current in the car’s coil, recharging the maglev car’s battery. This is also made possible through resonance, where if both coils achieve the same resonance, energy can travel in a stream from the rails to the car from meters away. Possible experiment: Create two coils, one with a battery and one with an LED, and attempt to preform inductive coupling. In other words, I will try to recreate this experiment: We are pretty close to using inductive coupling in electrical vehicles thanks to the breath through of the creation on OLEV (On-Line Electrical Vehicle) created by the Korean Advanced Institute of Science and Technology (KAIST). They already created their first vehicle that uses inductive coupling to recharge the bus’s electrical motor while driving, as opposed to other electrical vehicles which relies on stopping and recharging (which means it is more time efficient). Pros Higher speed capability and lower travel time Due to the fact that Maglev car does not contact the service, it has an advantage over the common four-wheeled cars: lack of friction. Road to tire friction has always been the force that restricted a car’s ability to achieve maximum speed and have always resulted in loss of energy. However, the maglev car makes no contact to the road and completely ignores friction, allowing less energy loss and maximum speeds. Another friction that slows down vehicles is air resistance to maximum speeds of around 300-350 mph. However, if maglev highways were to take place in low pressured tunnels, where there is less air, then maglev cars can ignore both surface friction and air drag, achieving speeds up to thousands of miles per hour. There have been predictions from sources saying that if Maglev highways were to built, cars can reach Los Angeles from New York in just an hour. Less accident rates and higher safety (guided maglev railways) Maglev relies on magnetic rails in order to function; therefore the path of the car will be restricted to the magnetic railway. This is a good thing since this reduces the chance of “losing control” of the vehicle, which often results to car accidents. Also, the distance between the cars as well as the speed of the cars will be controlled by frequency of electrical power that feeds the car. Constant supply of energy without recharging The maglev car is an electrical car that uses inductive coupling (as demonstrated in Korea’s ONEV) by transferring electricity from underground power lines to the wires of the vehicle connecting to the motor. No need for oil and gasoline & no pollution The maglev cars run completely on electricity with no need for oil. This would only significantly reduce the amount of human conception on oil (since automobile and transportation is the main consumer of oil) , it would also significantly reduce the amount of CO2 output in the air. If millions of these were used on the road instead of gasoline powered cars, it will cause a great impact on global warming and the energy crisis. Quiet Maglev trains have a reputation of being quiet trains due to the use of electrical motors and magnetic suspension. Same goes for the future maglev cars. Reasons for Maglev car being a top choice in the future Why preferable over solar powered cars? Weather independence This is one of the huge advantages over solar powered cars. While the results between maglevs and solar powered may be the same in bright daylight, solar powered cars will lose their main source of energy in a cloudy or rainy day, or more common problem, at night. However, maglev cars is completely weather independent, capable of functioning at its highest during sunny, rainy, cloudy, and nightime weather conditions. Even though solar powered cars can store in electricity that it got from its solar panel to use during non-sunny condition, the weight of the battery reduces the efficiency of the car, giving it an additional disadvantage while the maglev cars is weather independent without losing its efficiency. Significant increase in speed as opposed to decrease in speed Another disadvantage of solar powered cars is their reduction in speed. Solar powered cars are designed to run even slower than gasoline powered cars in order to function properly. However, maglev cars is the exact opposite, it is designed to move 3 times faster than the top speed of gasoline powered cars (due to reduction in surface friction and air resistance). While speed is the great weakness of solar powered cars, it is the maglev car’s greatest strength while both of them have a fair share of other similar advantages. In this situation, Pro + con (solar) loses to Pro + Pro (maglev) Easier maintenance/increased durability The main source of power for solar powered cars is its solar panels, which will be completely exposed to the roof of cars. Due to such exposure, the solar panels have a higher chance of being damaged from outside forces which can cripple the car’s ability to receive energy from the sun. In addition, solar panels are expensive to maintain and replace. Maglev cars have no solar panels to be worried about. Energy efficiency Maglev cars only consume 0.4 megajoules per passenger mile, which is two percent of the energy consumed by the typical 60 mph car. In low-pressured tunnels, its energy consumtion would decrease to the equivalent of 10,000 miles per gallon. Why Maglev technology over normal four-wheeled cars? High energy efficiency As explained before, Maglev cars only consume 0.4 megajoules per passenger mile, which is two percent of the energy consumed by the typical 60 mph car. In low-pressured tunnels, its energy consumtion would decrease to the equivalent of 10,000 miles per gallon. Less need for highway maintenance Maglev highways would last 50 more years than today’s roads due to the lack of mechanical contact between the car and the ground where the mechanical contact of today’s car constantly wear down the road, especially heavily weighted vehicles. Maglev cars also have a higher life-spawn than normal cars, airplanes, and normal trains. Quiet As mentioned, Maglev trains have a reputation of being quiet trains due to the use of electrical motors and magnetic suspension. Same goes for the future maglev cars. Support for the rise of robotic/driverless cars Driverless cars are increasingly becoming popular and more possible as shown by the creation of Google’s smart driverless cars as well as several robotic cars creations by several universities in the DARPA Grand Challenge. With the sensors of robotic cars, cars will have the ability to navigate through places safely without the need for a driver, allowing “autopilots” to many places The fact that the maglev highways use guided railways, driverless robotic systems more easily can be installed to maglev cars and give more effective results in combination with cars on guided railways than normal cars today (due to less need of a complex navigation system). Maglev and driverless robotic car systems work great together. Cons Expensive cost to build Maglev highways The only negative aspect of maglev car is the fact that maglev highways have to be created, which won’t be cheap. In order for this to happen, there has to be large funding to the project for the creation of not only maglev cars itself, but an actual system of highways for it. While there has been tests and sample Maglev car railways that show that this is definitely possible, the cost of the project and building a network of maglev highways is the only thing that is stopping its production. However due to the fact that there is a significant decrease in maintenance and fuel costs as well as energy efficiency, this can be something that can pay off in the long run, if it is invested in today. I have high faith for the success that will come from production of these cars and these highways. Any critique on this? Is this possible? Any advice in what I can do to make a small model of the maglev car (not the entire thing, just a small demo of it) or any correction to the concepts that I posted? Some of these may look ridiculous to you as I am only a high school physics student. However, I really want to interact with physics more and use these concepts to create something new and interesting, like this maglev electromagnetic hover car.
