How do you build an engine that runs on water?

Question

i've been searching the internet to see how to build em or convert normal engines to run on water (hydrogen) but i couldnt find s*** all

Answer 1

There have been many attempts to do what you ask.  The problem is that to get enough hydrogen gas from water takes a lot of electrical energy in an electrolosis system.  The demand for the hydrogen will outstrip the supply if the vehicle electrical system has to try to power the electrolosis.  The idea is only feasible if a method of extracting much more hydrogen gas from water can be done with very little power.

Answer 2

Yes it is quite possible to make such engine. A friend of mine tried to use HHO alongwith CNG and the result was very good.

Answer 3

It will cost you more money to split water by electrolysis to hydrogen and oxygen than from running on gasoline.  Not to mention the conversion cost.

Answer 4

you can't because it's not possible.

But there is a big scam around, and if you are crazy enough to waste your money and time on it, just search for HHO and you will find lots of scam artists eager to sell you equipment.

Answer 5

A.  get a lot of water.

B.  Put it in a tank above the vehicle to be driven.

C.  Let the water go through a pipe to a water-wheel below mounted on the car, attached to a transmission.

D.  Drive vehicle.  

E.  When water runs out, refill.

Answer 6

First you need to split the water (H2O) by electrolysis into hydrogen (H2) and oxygen (O2).  This requires some sort of electrical input.  The current best method for this using green energy is solar produced electricity.

Next you need an engine to burn the hydrogen which burns a lot faster than gasoline or diesel.  So to properly use the hydrogen you should use a fuel cell, which is a sort of battery with specialized membranes separating the hydrogen and oxygen.  This uses an electrolyte to transfer H+ ions to oxygen to produce water while also sending electrons through a load, producing power.  This is your most effective use for the hydrogen fuel... however fuel cells large enough to power a vehicle are VERY expensive since they're still being researched today.

So you should probably stick to your gasoline or diesel engineer or get a bus pass since fuel from water isn't going to be a likely option for some time yet.
