So the video proves we could mine... wherever the street cleaners have been dumping their catch daily for the last 40 years and derive precious metals. The dump? Futures of mining!
As for your accord and the cat troubles... I don't think a 2.3L inline 4 is likely to have two cats, do you? Pop the hood and look. The six cylinder was years later, I thought.
Toilets will not help you with this problem. Save them for their primary design purpose.
