Water-Fuel Powered Car

 

I'm talking about a water-fueled car; and plenty of scams have started this way, but not a single useful invention.  Okay, I'll try just once to explain this but I don't want to get dragged into a debate about it because frankly it's just too silly.

 

Yes, hydrogen fueled cars are a great idea; and yes, hydrogen can be obtained by electrolysis from water; but NO, water is not the fuel (i.e., the energy source).  You still need an external energy source to do the electrolysis.

 

The energy required to separate a water molecule into hydrogen from oxygen is exactly the same as the energy obtained by recombining hydrogen and oxygen, i.e. burning it as a fuel.  There can be no net gain in energy -- in fact, inevitably there is a net loss due to heat, friction, electrical resistance, etc.  An engine that runs on hydrogen can never generate enough electrical energy to extract the hydrogen it needs for its own fuel, let alone having energy left over to do any useful work.

 

Hydrogen fueled cars would be very cool because hydrogen is conveniently portable for cars and energy-dense compared to a battery (i.e., can store more power per unit weight).  Generating hydrogen by electrolysis is a cool idea because it can transform a non-portable energy source (e.g., hydroelectricity) to a portable one.  And fuel cells are very cool because they are much more efficient at converting fuel to power (electricity) than internal combustion engines.

 

But no matter how you shuffle these technologies around, and no matter how efficient or advanced they become, you will never get more energy by combining hydrogen with oxygen than you consumed to split them apart.  It was called "conservation of energy" when I learned it in about Grade 5.  Scientists now prefer to call it the something-or-otherth law of thermodynamics (I can never keep the numbers straight), but it's the same thing.

 

 

Are you talking about the water fueled car? If so, how many other inventions started off like this.

 

There are a lot of protypes I seem to be coming across for energy efficiency and better for the environment, but whether they are viable or not it is a stepping stone for more investigations, this is the only way to develope and learn. The first computer was a huge thing but look at it now, small light weight and can sit on your lap  

 

if you're not talking about this water fuel car, ohhhh well

 

Trust me, folks -- DO NOT invest a dime in this scam.
