The Japanese technology is correct and does work small-scale so far in labs as well as small electical devices that are available right now. The challenge will be to bring the system up to more power and size. Many of the comments are funny. Some remind me, however, that the educational system in this country has failed. There are several companies working on the breaking of hydrogen/oxygen bonds to produce hydrogen generated energy. In the meantime, hybrids will be the best transitional approach, And by hybrids, I mean the ones that produce much more energy than say a Prius. An example is the extreme hybrid by Trinity(100-150mpg). It will do for the near future for trips under an hour, and probably two hours in a year or so.
OK, Acuman. But I really don't get it. Doesn't it take energy to "break...hydrogen/oxygen bonds."? Where does that energy come from? To me it seems like basic thermodynamics. Which of course, most people have no clue about.
