significant capital investment and so every additional unit they sell offsets that so scaling up production would be a good thing financially. Of course if the demand isn't there then there's not positive cash flow. I'm always skeptical of reports like this, I'm sure all these companies assumed early losses, the question is how they're are tracking to their projected ROI...if that hasn't panned out as expected the return is longer than expected but losses aren't necessarily a bad thing for new technology. They claim losses for taxes proposes and gain market share going forward
