How Deep Could We Dig for Infinite Geothermal Energy?

The deepest hole ever dug was by the Soviet Union, starting in 1970. The project reached 7.6 miles deep and took 20 years. We are now attempting this once more, but this time, to harness the immense power of our planet for clean, renewable energy. However, digging deep holes is not as easy as it sounds. We speak to some of the leading experts attempting to do this, discussing the pitfalls and what they hope to gain from this endeavour.

Sweden's Stealth Navy: Visby Corvettes and Gotland Submarines

Sweden favors stealth over brute force—and nowhere is that more apparent than in its two naval marvels: the Visby-class corvette and the Gotland-class submarine. Engineered for one of the most complex maritime environments in the world, these platforms embody the Swedish Navy’s philosophy of striking silently, surviving unpredictably, and defending decisively.

30 Years Without Refuelling: Is the Future of Ships Nuclear?

Though aircraft carriers and submarines powered by nuclear energy have existed for years, they have yet to be fully embraced by the commercial shipping industry. But now, with the frantic push towards greener, more sustainable ships, eyes are turning back towards nuclear power.

The Science of Tank Killing: Javelin, TOW, and Matador in Action

Javelin, TOW, and Matador missiles are designed to defeat the toughest armored threats on the battlefield. Each uses different methods to identify, track, and destroy tanks—whether by hitting from above, defeating reactive armor, or operating in confined urban terrain.

What Happened to Libya's Great Man-Made River Project?

The Great Man-Made River (GMMR) is an extraordinary network of pipelines, hailed as the world's largest irrigation project. Stretching across Libya, it channeled fresh water from the ancient Nubian Sandstone Aquifer System to the bustling northern Mediterranean cities, including Tripoli and Benghazi. Covering a remarkable distance of up to 1,600 kilometers, this system supplied 70% of all freshwater used in Libya, transforming the arid landscape and supporting millions.
