well you can make Ammonia renewably . The fundamental inputs are Air , Water and Energy . If you use wind turbines you can easily take DC off those . <| sep |> I agree , when it works . Got a titanium model from sneaky pete and it worked exactly twice , before giving me redblue police lights thus signalling a defect . Grasshopper is sending me a new backend This better work or it ' s going back to Sneaky for a refund . Now I will say the two bowls I got out of it were top notch , thick heavy vapor , fastest heat up on a Vape i ' ve ever used , and I have around 8 vapes alreadyVAS kinda sucks . Currently waiting on a DaVinci IQ that should have been here a week ago ! Seems to be a real trend in high end vapes anymore , delays in shipping , delays in release etc .
