" Why else would the Qld GOV back us?"The govt wants the jobs - they have NO idea of your viability. They have given you some money for the feasibility study so they can get an idea if you are really worth spending anymore money on.
As for Siemens they are a contractor NOT a partner no matter how much rampers or the company likes to spin it. Thus far Siemens has not committed any funds to any of your ventures - they have committed resources for which they expect to be paid.
