Keep it simple. Do one thing. Test. Evaluate results. Evaluate cost-effectiveness. Then do another.

I snipped the post but I think this is the key but in the reverse order.

If you get the HHO combustion working properly, then you will be melting the metal. So i'd be aiming for that. If you get that far, then you're probably on the right track.

Spraying water mist to cool it down isn't so hard. Just getting it all rolled together to work seamlessly will be .. time consuming.

With a lot of attempts at getting HHO working with petrol-engines people often gave up when they burnt out the head-gaskets. But SM had some type of recirculation system where he'd use exhaust steam as an input.

Anyway, I've never done it and may never but if you do get any real progress please post. Just work through it one step at a time. There are other forums that have a wealth of attempts by people on this. They'd probably be able to help more perhaps.
