IDEAS The steam engine changed the world. Artificial intelligence could destroy it. The US and China have to stop thinking of AI as an arms race.

Nuclear rocket propulsion experts say the technology will advance space travel the way a steam locomotive revolutionized the horse-and-buggy days of transportation.

Looking back at the 40s, 50s, 60s, and 70s, you'll likely come across a production series car or concept car that is so beguiling and odd that it warrants a hearty "What the hell is that?" Like the 10 ...

Nuclear engines have been powering submarines and other military ships since at least the 1950s, as noted by the U.S. Environmental Protection Agency. The heat from the reactions creates steam ...

Norway’s near-total shift to electric vehicle sales signals a transformative moment for the global automotive industry, with major implications for combustion engines.

Naval ships and submarines all come with a designation that generally describes what they do and other key specifications.

A nuclear rocket engine which could halve the flight time to Mars is now under construction at Pulsar Fusion.

By program's end, design proposals for everything from nuclear-powered rockets, submarines, missiles, hydrofoils, and even helicopters were floated.

Installation of the high and low pressure cylinders of the steam turbine for unit 3 of the Haiyang Nuclear Power Plant project in China's Shandong province has been completed.

General built a giant, futuristic steam engine. The reaction process starts in a huge tank filled with liquid metal (lead and a little lithium) that’s spun around furiously to form a cavity.
