    Its an interesting concept, but will be expensive to put into play. You have to remember that manufacturers of conventional hydro drives have economies of scale on their side now.

    The first generation of equipment using water will be very expensive to the end user or will be subsidized by the manufacturer, much the same way hybrid-drive automobiles have been up to now. Still, Detroit (and the rest of the auto industry) has the incentive of keeping their corporate average fuel economy up, so each hybrid they sell allows them to sell a gas-guzzler. Not sure if hydro drive manufacturers will find an enabling factor like that, so the end user will have to bring this into play.

    On the other hand, it's curious that someone hasn't tried to work this out before now, like during the gas crunches of the 1970s. Whatever the case, I suppose we can look forward to more innovations to reduce dependence on petroleum products as time marches on.

    That will never happen untill they can control the rust in the system.

    Controlling the rust is not that difficult,the problem lies in the cost of materials to do so. Good quality stainless steels are probably the easiest but there are many advances in plastics that could provide a solution.

    Don't forget that water boils @ 212 degrees farenheit. Current hyd oil will take much more than that, and synthetics even higher, not to mention water's lack of lubricity. I'd be willing to bet that technology is a long way from being really feasible, as others have mentioned, It will be real pricey.

    Simple cooler will take care of the heating.
    Pricey it will be,as any new technology is,but once it matures it is a great thing.

    Pressurized water boils at a higher temperature then water at atmospheric temp, hence the radiator cap on your car.

    Water is a nice environmentally friendly idea but if you notice, it is not "tap" water thy use. It is deionized water. It is expensive to deionize water. Another sidenote is that deionized water CANNOT be ingested as it will draw the salts and electrolytes from your body quite possibly resulting in death.
    On the plus side, it is neat to see new things being tried.

    Unfortunately, SUVs are STILL exempt from CAFE standards, so all the manufactures are doing now is pushing SUVs. Doesn't create much incentive. If SUVs were subject to CAFE as well, the need to sell hybrids would REALLY be there!
