Take a look at this site that sells water for fuel conversion kits. Is this for real?

...or not? Please give a reason for your yes or no answer.

Answer 1

No, this doesn't work. It defies the laws of thermodynamics.

Water Is a very stable molecule. It gives off a lot of energy when it is created. This also means that you have to give that energy back in order to pry the molecule apart. The best way to separate hydrogen and oxygen is to use through using a little electrical current system. This is useful, say, on a submarine where you need gaseous oxygen in a place where oxygen is difficult to obtain. I'm pretty sure it's also used in space.

However, if you do what is being described by the website, you're ripping the water molecule apart in order to extract the energy given off when it is put back together. So it's basically an inefficient way to get energy from your battery into your engine. Claiming that this requires only a small amount of energy from the battery is a blatant violation of the second law of thermodynamics and I wouldn't trust anything said on the web pages you linked to.

Answer 2

NO. Sorry but there is no way to separate water into its constituent gases in a manner that is efficient enough to use those gases as fuel. The common method of using electricity is in the neighborhood of 50% efficient.  People want to believe that this technique is viable but the science is not there.

Answer 3

not sure if this is the exact site, but my husband & his friend are installing similar mechanisms on their trucks from instructions they got off the internet.  they are mechanically inclined types and i can tell you my husband is fully sure this will work to reduce his gas mileage.  he has been researching for months.  i'm not ready to have them install it on my caryet...the jury's still out for me, i guess. but apparently the concept behind it is solid.

Answer 4

it doesn't defy the laws of thermodynamics, it is supposed to burn the gas with better combustion dynamics, hence providing more energy with less fuel.

Read the article below, it's based on ultra-lean burn combustion engines.

splitting water into H+H+O is very simple and has been done for years. It does require a bit of energy to do this, but if you're getting a lot more energy out of your gasoline, then your mileage will increase. Doesn't seem to work for all cars, but a lot of people are getting significant increase in mileage.
