You know my little cousin was talking to me earlier in the year at some family thing, and he was on at me about helping him make a 49CC 2 stroke petrol/oil mixture engine run on water... It was pretty hard telling him it wouldnt work, because they'd be no lubrication, and it's just not the right engine, period. He thought he'd invented something lol, when he was talking about how to get the water, and devide it all out into it's originall make up and all this fun diddly-un stuff to get the hydrogen.

But hey, he learnt a lesson.

And now he's gone back to the drawing board with the right kind of idea... It's up to him though to get it to work out,.
