Ann: Clarification Announcement, page-17

Nice of them to give an update and address shareholders questions.
Alex is making a decent effort however a few points:
Still no hard specifacations of the products content??
They say the tanked gas was not hot enough??
According to elgas’s website: http://www.elgas.com.au/blog/486-comparison-lpg-natural-gas-propane-butane-methane-lng-cng
Which Burns Hotter Liquid Propane (LPG) or Natural Gas?
LPG burns slightly hotter than natural gas.
LPG - propane - burns ar 1967ºC or 3573ºF.
Natural gas burns at 1950ºC or 3542ºF.
However:
LPG Needs More Oxygen


The second difference is in the oxygen to gas ratio required for proper combustion.
LPG requires an oxygen to gas ratio of approximately 25 to 1.  
Natural gas requires a ratio of around 10 to 1.  
To achieve this difference, LPG is typically provided in a smaller quantity but at a higher pressure, drawing more oxygen with it into the combustion process.

The only explanation I can come up with is the lab is at very high altitude and has low oxygen causing burning efficiency issues??

To be honest I still don’t know if I buy the gas would not burn hot enough..
The good news is industrial grad is still worth a lot of money, good luck holders hope this has a bounce, but be wary guys
