Time and Joint Ventures are the issues really...without JVs', of course, GRC haven't the wherewithal to make/sell machines. The Schlumberger deal is likely to be at least two years before any potential significant revenue is achievable. Apart from tyre units which need a year to complete, why should any newer partnerships produce any sooner? Assuming no remaining technical problems, it looks like the only reason a tyre unit isn't being made/sold is cash or lack of:but there lies the rub..no company seems willing to 'take the plunge'. Chicken and egg really....Or ...have they finally got a taker? AIMO
