FACTS OF BERMUDA TRIANGLES

                      FACTS OF BERMUDA TRIANGLES

Bermuda Triangle is the greatest unsolved mystery of the modern age. Also called Devil's Triangle.
It is a triangular shaped area in the North Atlantic Ocean, from Bermuda Island to Miami, USA and Puerto Rico. Hundreds of people and numerous boats, ships and planes have disappeared inside this triangle. Reasons given for these disappearances vary from scientific to sheer myth. Here are 10 Shocking facts about Bermuda Triangle :



Fact No. 1
The Bermuda Triangle is not small. In fact, it is quite large and covers an area of 440,000 miles of sea. This is larger than the combined area of Rajasthan, Madhya Pradesh & Maharashtra.


Fact No. 2
The triangle is certainly not fixed and its effect can be experienced outside of the triangle too.


Fact No. 3
The disappearances are ascribed to UFO's and alien activity, city of Atlantis lost under the triangle, and various other technical, natural and geographical reasons.


Fact No. 4
Whenever any plane or ship disappears in the Triangle, its debris cannot be found. The reason behind this is that Gulf Stream runs near the triangle, which quickly gets rid of the debris.


Fact No. 5
At least 1000 lives are lost within the last 100 years. On average, 4 aircraft and 20 yachts go missing every year.


Fact No. 6
Inside the Bermuda Triangle, US Government has AUTEC (for Atlantic Undersea Test and Evaluation Center), which is located on the Andros Island of Bahamas. Here US Navy tests their submarines, sonar and other weapons. However many are of the view that it is more than just the testing center.


Fact No. 7
People have experienced electronic fog in the triangle, which can be a Time Travel Tunnel too. Pilot Bruce Gernon claims he lost 28 minutes after flying through a time-warping cloud tunnel. The plane went missing from radars, only to re-emerge in Miami Beach. (Source: The Fog by Bruce Gernon.)


Fact No. 8
One of the biggest and famous losses of US Military occurred in 1945. Five US Navy Avenger torpedo bombers flew from Fort Lauderdale, Florida for a sortie to the island of Bimini. The mission had 14 men. After about 90 minutes, the radio operators received a signal that the compass was not working. After that the communication was lost. The bombers were never found. The three planes that went for their rescue also disappeared.


Fact No. 9
The first person to report about Bermuda Triangle was Christopher Columbus. He wrote in his journals that inside the triangle, the ship's compass stopped working and he also saw a fireball in the sky.


Fact No. 10
Bermuda Triangle is one of the rare places on earth where the compass does not point towards Magnetic North. Instead of that, it point towards true north, which creates confusion and that's why so many ships and planes lost its course in the triangle

MY THOUGHT ABOUT THIS TRIANGLE IS ;

REGENERATIVE BRAKING SYSTEM

REGENERATIVE BRAKING SYSTEM

    


Introduction:
               
                           A brake is a tool that enables in deceleration of a moving object; they use friction to convert kinetic energy into heat. Conventional braking systems use this mechanism. Once the brake pads rub against the wheels of the car, excessive heat energy is produced. The heat generated is lost into the air nearly accounting for about 30% of the car’s generated power. The project here “Regenerative Braking System Project For Mechanical Students” introduces a different braking technology.

                           In this system, regenerative braking mechanism reuses the energy created by the braking process and uses this energy to charge the battery for further use. Generally the energy lost in the conventional use is transferred to the generator of the rotating wheel and is given to the battery. This saves a lot of energy.

          Regenerative braking is one of the emerging technologies which can prove very beneficent. The use of regenerative braking in a vehicle not only results in the recovery of the energy but it also increases the efficiency of vehicle(in case of hybrid vehicles) and saves energy, which is stored in the auxiliary battery.

Working:

                   The driving system of the vehicle is responsible for most of the braking process. As soon as the driver steps onto the brake pedal of the vehicle (either hybrid or electrical), the brakes put the vehicle’s motor in the reverse mode enabling it to run backwards causing the wheels to slow down. While in the reverse mode, the motor operates as an electric generator feeding this electricity into the vehicle’s batteries.

                      Most of the hybrid and electric vehicles in the market employ this technique to extend the life span of the battery pack. It is highly beneficial to use regenerative mechanism as it reduces pollution and also increases the engine life.

Flywheel energy storage:

                  The energy (mechanical) stored in the flywheel is directly given to the vehicle so as to boost its acceleration instantaneously, whenever needed. Generally, the method of transmission of energy directly to the vehicle is more efficient rather than storing it in the
battery, as it does not consists of the conversion of energies. 

                  As, during the recharging of battery, mechanical energy is converted into electrical energy and during discharging electrical energy is converted into mechanical energy. So, due to these conversions transmission loses occur and the efficiency reduces. As, in the other case, there are no transmission loses since mechanical energy stored in the flywheel is directly transferred to the vehicle in its original form. Because of the instant energy supply and high efficiency these type of system is used in F-1 cars.

Future Scope:

                  As in regenerative braking system about 30% of the energy is recuperated, also the system of regenerative braking increases the weight of the vehicle by approximately 25 kg. So rather than manufacturing the metallic gears and metallic flywheel, carbon fiber can be used which will not only reduce the weight of the system but also it will reduce the transmission loses.

Conclusion:

                          In this project Regenerative Braking system, the regenerative brake captures about half of the energy wasted and is utilized by the engine whereas in conventional brakes, 80% energy is wasted. Hence fuel consumption is reduced by 10 to 25 percent in regenerative braking. Not only this, speed of the vehicle is also greatly enhanced by this mechanism of braking.

Application:


  • Better fuel economy
  • Reduced CO2 emissions
  • Approximately 30% saving in fuel consumption
  • The lower operating and environment cost of the vehicle
