Subject: My son found plans to fuel a vehicle w/water. Is this feasible & dangerous?

My son is 12, and fascinated with vehicles, speed, and power.  He wants to try 
to build a go-cart, and put together an engine which runs on water.  It is 
called "fuel from water", and he got it from a website.  Is this idea of using 
water as fuel even feasible?  If so, aren't we talking about hydrogen, and 
wouldn't it then be a BAD idea?  I have received very little definitive 
information about such an idea, but plenty of scoffing.  I want to encourage my 
son to explore this area of science to the degree he is able to-without blowing 
himself up.  Thank you sincerely for your time.
