Interesting articles on TTT, page-2

The fusion process seems to offer incredible potential for sure. I have been accumulating shares for a while and hold high hopes. Have watched their videos several times and it amazes me that:
[a] a powder is sprayed but there seems to be no dust from surplus/peripheral spray ? No containment room needed ? No concerns over factory staff breathing in powder? The above article was  also the first realisation for me that titanium it is flammable material too...no dust explosion hazard ?
at supersonic speed thru fine nozzles, there is no noise problem ? I would expect nozzle wear to be rapid too, I see nozzles are mentioned as a consumables sales item, must be tough stuff , especially if get into tungsten etc spraying.

Not knocking the process at all in my ignorance, just commenting as a very interested, production engineering background observer. Would love to visit the facility if/when a shareholders open day is held !
Congratulations to Jeff and his team, may your/our wealth grow exponentially !!
