    That is the epitome of an annoying racket of marbles and nuts in a tin can. That noise will easily give you early hearing loss. Unless they have a miracle noise absorption gadget, I don't know why anyone in their right mind would buy them.

    I would like to see it, the claimed hp and efficiency would be nice.
    I'm not sure how the torque curve runs out. The noise can be addressed.
    Also this noise about lubricating the crank, your existing engine does not run in oil,
    if it wasn't for the oil pump pushing oil to the crank it would seize.
    Since the old dipper splash lubricated engines there hasn't been an engine that used the crank to lubricate by being in close
    proximity to the oil level other then low power short lived small engines

    They've been R&Ding the idea for years now and I don't think they have anything in production. In 2015 they reportedly had 5 different engine applications including passenger vehicle, military, light/heavy commercial, and marine stationary power generation. The noise issue probably best suits industrial applications.

    For now I'm more interested in hearing some news about real world practical stuff like GM's inline 6.

    Opposed piston engines aren't new or "revolutionary". They've been around since the at least the 1930s, and have been used in everything from industrial to marine to aircraft applications (they've been used on submarines since the 1940s). They do make decent power and are fairly efficient though.

    There's been a few duplicate articles lately with little to no new info. Hopefully this article provides a bit more specifics on the engine design.

    Best I have seen. One video on the side is well worth watching as they simulate the engine in operation.

    Gonna watch both later. My first impressions are very positive. Love the layout of the turbo and injector pump. Must go right now but will look later today when I can make time. One thing bugs me. That stupid flashing LED light angle on the front sure is obnoxious to me. That's why they make rolls of black tape.

    Vern - Thanks for the links.
