Hmmm...I'm one of the resident idiots of Mudcat, but it seems to me (Tweed bumbles forward shamelessly with uneducated pronouncements), that storage of the finished product is not viable. The hydrogen must be burned as fuel as soon as it's produced, so have they thrown that idea out already or did the researchers go for the gas tank with all the infrastructure involved idea first?? Is there any possibility of super capacitors (smaller and less weight than batteries) being developed to store solar harvested electricity and then be used as onboard cracking power, wherein the vehicle fills up a water reservoir and makes it's own fuel as needed?
