Existing technology.
www.aquamist.co.uk, or just use the same stuff that's used for fuel delivery in a parallel circuit.

Trade a 15 gallon fuel tank for a 10 gallon fuel tank + a 5 gallon water tank. Same space, only a little more weight. If you really think the extra 12 lbs the system weighs when topped actually makes a real-world difference...

Distilled water costs $0.66/gal at Walmart. Also, IIRC, the BMW system is nearly a closed system that reuses the water, so you rarely have to top off the system.

And don't forget you have to stop the engine at some point. what happens to the cylinder that is full of unexhausted water vapor? can you say oxidation? Maybe we will have stainless or ceramic blocks.

An engine block is exposed to more water just due to normal humidity that it is when you add water injection to the mix. I'm pretty sure it would be fine. Hell, cast-iron steam trains didn't rust out in 20 minutes. A modern engine designed for the water cycle would be no different than a current motor that has to deal w/ condensation and the like already. In fact, I'll bet a water-stroke motor would run cleaner due to the constant steam cleaning it gets.

Hope I'm wrong, but my pesimistic side is winning this one, and I say the glass is 3/4s empty.

He didn't say it makes more power, he said it makes the same power with less gas... which is the whole point. I said it makes more power, because the next step (since you've already got a water delivery system in place) is to add water injection to the gasoline power stroke and make more power.
Do I expect this to revolutionize the automobile industry? Nope. But I recognize that we're entering a new era of car design where we're going to see alternatives to the normal gasoline motor. Hybrids, E85, diesel, water-stroke, pure electric, hydrogen, etc... people are finally going to have choices. And as the kinks are worked out on smaller production cars, we'll start to see these technologies in large scale vehicles.
