One thing you can guarantee about this country: we’ve got a great grapevine.
If a thing really works, and is genuinely superior, the word goes out on the grapevine and that product becomes a success.
If this water fuel thing really works well, eventually everyone will have a cousin or a close friend telling them that “hey, this thing really works”, and it will be installed on cars all over the country.
There is also a lot of sales bull pucky and lots of get rich quick scams that we all hear about.
I’m going to reserve judgement. If this thing really works, my mechanic will soon be suggesting that I install one on my car. (no, he doesn’t get paid, so he isn’t looking to make more work for himself, and he isn’t going to install something that will damage my car and give him an unneccessary repair job.)
If it doesn’t work, that information will be floating around the web soon enough.
