No one like them? There are PLENTY like them. Many companies use CO2 extraction and many companies grow produce using hydroponics. Nothing unique or proprietary about TRTC's products.
Being unique is a subjective opinion... until it is shared with everyone and majority deems it truly unique.
I am afraid, as a relatively young company, TRTC thinks he is UNIQUE from the reflection in a small pond in the bottom of a well, until he comes out to the real world.
