  • Infiniti VC-Turbo engine

    Infiniti is destined to become the first major automaker with a variable compression engine. The engine, dubbed the VC-T (Variable Compression-Turbo), has the ability to alter the compression ratio, i.e. the volume of the combustion chamber when a piston is at the bottom of the stroke compared to when it reaches the top, whereas in conventional engines this ratio is fixed. ALSO SEE: Audi unveils suspension-energy regeneration technology The result is an engine whose displacement changes as required, i.e. a larger displacement for high-load situations and a smaller displacement at other times...

  • Transit Elevated Bus (TEB) - Image via China Xinhua News

    China’s Transit Elevated Bus (TEB) made headlines last week after the company behind the project, TEBtech, conducted a first real-world test. However, questions have been raised as to whether it's just one big scam. As China’s Global Times points out, much of TEBtech's capital has been sourced via online peer-to-peer lending. The form of lending has been rocked by several scandals in China recently, with some turning out to be Ponzi schemes. ALSO SEE: Are you game to drive through an underwater floating tunnel?
