Hyperloop project

Why in news?

The proposed Pune-Mumbai Hyperloop project, may be scrapped by the state government.

What is the Hyperloop technology?

  • It is system of magnetically levitating capsules (pods) that are sent at high speeds through low-pressure tubes.
  • It envisages tube modular transport system that runs free of friction.
  • It uses linear Induction motors in it to control speed of pods.
  • It would also be thrice or four times as fast as a bullet train, with an average speed that would be twice of an aircraft.

How it works?

  • The high speed is achieved as the pods, which carry passengers, move using magnetic levitation.
  • The speed increases further due to the near-vacuum conditions inside the tubes, which reduce resistance to the pod as it travels within the tube.
  • Note: Magnetic levitation is a method by which an object is suspended with no support other than magnetic fields.


  • Once developed fully, it could make the transportation of people and goods easier, faster and less expensive.
  • Hyperloop departures could happen with a low frequency of a pod every 20 seconds which is not possible in railways.

Fact For Prelims

Submarine-launched ballistic missile, K-4:

  • Test- fires recently.

Key facts:

  • Range: 3,500 km.
  • The Circular Error Probability (CEP) of the K-4 is much more sophisticated than most countries which possess similar missiles.
  • The CEP determines the accuracy of a missile.
  • The lower the CEP, the more accurate the missile would be in targeting.


  • It is the flagship showcase of the Indian electrical industry and a platform to connect the world with the Indian industry in respect of technology, new trends and innovation for the future energy transition.
  • It is a platform for knowledge-sharing with a strong focus on electric vehicles, Internet of Things (IoT), storage solutions and renewable energy.
  • It is supported by the Ministry of Power, Ministry of New and Renewable Energy and Ministry of Heavy Industries and Public Enterprises, Government of India.
