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 secondswhich is not possible in railways.
Fact For Prelims
Submarine-launched ballistic missile, K-4:
Test- fires recently.
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.
