I think that is rather cool, except seperating water into hydrogen and oxygen is electrically expensive. Though, there has been progress in that regard. It has been found that the bacteria used for cleaning water at water treatment plants, when deprived oxygen, and then provided 10% of the electricity normally required to seperate the base atoms of water will take the O2 for themselves and release the hydrogen. Cheap hydrogen for fuel cells anyone?
And for the car lovers (or haters, depending on how you go with this) there isa a DIY car insignia service...
Hmmm.... Will anyone believe the "R-Type" logo on my Dodge pickup? :-P Actually, I am expecting SUV haters to make insignia's to replace the factory spec insignias on the SUV's they hate. Like bumper stickers, but more subtle. If you could change the model or make logo on your car or someone elses, what you you replace, and what would you replace it with?
