The Changing Face Of India’s Defence Sector
In Perspective
India is one of the largest importers of defence equipment worldwide. However, the government is now planning to reduce the country’s dependence on imports with focus on indigenous production of defence equipment. With a slew of recently announced reforms, the defence sector will surely gain more momentum in its path to self-reliance in defence production

SMART WORLD
Hydrogen As A Fuel For Next-Gen Mobility
Hydrogen-powered vehicles are more efficient than a combustion engine as no greenhouse gases are emitted. However, the process of generating hydrogen should also be green. Commonly used processes for separating hydrogen from other substances include steam reforming of methane, gasification, and electrolysis
SMART WORLD
Wind-Solar Hybrid Systems To Improve Grid Stability
Using renewable energy sources like wind and solar for power generation has helped in reducing carbon footprints and made power available to non-electrified remote areas. A hybrid power system that combines the benefits of both sources can improve the reliability and stability of the grid to deliver non-intermittent electric power
