I have been looking into the details of how to run your car on water and one of the things that I can’t seem to find concrete information about is the cost. I understand that there is a cost involved with buying the instructional “how to” guide but how much can one expect to pay for the materials to make the conversion kit and have it installed. I wish either my husband or I were a bit more handy and I had the confidence to believe we could do it ourselves, but I know that just isn’t the reality, we will need to hire someone. If you have any info about this, please let me know.
