Whimsical, curious, crazy and sometimes just monster-sized. With an unbelievable total weight of 260,000 tons, the floating factory “Prelude FLNG”, which can extract, liquefy and store natural gas on a mobile basis, weighs 26 times more than the steel giant Eiffel Tower. A marvel of engineering. In recent years, tomorrow has repeatedly unveiled vehicles that are not quite as heavy but no less spectacular. High-tech machines that deliver unimaginable performance on land, at sea and in the air. Have you ever heard of autonomous, emission-free container freighters, for example? Is there really such a thing? No, is there? Test your knowledge!
