I wouldn't exactly call it massive, its a pilot plant designed to produce 60 liters per hour, even the full scale plant will only be 4,000 liters per hour. The technology of Cielo is impressive to say the least, but there are still a lot of hurdles to overcome to go from small scale batch production to large scale continuous production.
I'm not saying it's a bad investment, just do your DD on that one.
Heres to hoping It goes to 4 bucks
