ucg technology questions

Hi, I'm trying to find more information on Ergo Exergy and where/how they have been developing their UCG technology.

There doesn't seem to be many details available publicly on the internet, so I'm hoping I may be able to get a bit more information from some of the CXY holders.

A few of the questions I would like answers to are:

1 - How many generators has Ergo actually built?

I know about Chinchilla and Majuba and Ergo's website claims that -

"Other commercial projects based on eUCG technology are currently in the initial stages of development in several regions of the globe, including the USA, Pakistan, New Zealand, India, and Europe"

- but I cant seem to find any confirmation that any of these projects have actually produced any gas.

2 - Is the design of the generator used at Majuba significantly different than that used at Chinchilla?

3 - How much money has Ergo spent on technology development over the last 10 years or so and how many full time engineers/scientists does the company employ?

I know I could email the company with my questions, but Im sure these same questions have been asked before by many of the longer-term holders of CXY, so if anyone could pass on the answers you received from Ergo or Cougar that would be very much appreciated.

Cheers
