India Turns Mumbai-Ahmedabad Experience Into Standard Blueprint For Seven New Bullet-Train Corridors

India’s first bullet train isn’t running yet, but the country is already planning seven more corridors. Using the engineering, designs and hard-won lessons from the Mumbai-Ahmedabad project, the government wants a single reusable blueprint for nearly 4,000 km of high-speed rail — from Mumbai-Pune to Delhi-Varanasi. The goal: build the next corridors faster, cheaper and increasingly in India.

India’s ₹84,084-Crore Deep-Sea Oil Search: What ‘Samudra Manthan’ Promises and Why Success Is Not Guaranteed

India is placing an ₹84,084-crore bet on the oil and gas beneath its seas. The Samudra Manthan scheme will fund 60 deepwater wells, modern seismic surveys and shared offshore infrastructure, with the government hoping to cut the import bill by ₹1 lakh crore a year. But deep-sea exploration is slow, costly and uncertain — and whether the bet pays off depends entirely on what the drill bit finds.

Beyond Lithium-Ion: How Sodium, Silicon, Sulphur and Iron Are Reshaping the Global Battery Industry

Everyone’s waiting for a single battery to replace lithium-ion. It isn’t coming — and that’s the point. Sodium-ion cells are reaching factory floors, solid-state batteries are on the road, and labs are reporting 600 Wh/kg lithium-metal cells. Beyond lithium-ion, the battery industry is splitting by purpose: the cell that suits a family car is the wrong one for a cargo aircraft or a power grid. The future isn’t one miracle battery, but a division of labour.
