Just where do you think that we will get the hydrogen ? From petroleum ? Or nuclear ?

The article says from your electric current (whatever that is - nuke or petroleum or coal etc.) or solar panels

As stated, the oxygen and hydrogen from water are seperated. The oxygen is released back into the atmosphere, and the hydrogen is converted for storage. The converter can run on solar power, wind power (for those near Lake Michigan), or plugged into a 110v outlet.
