HHO powered car Answered

One of my friends asked for my help for a project for his school expo. He wants to run a car on water and I have told him not to be too optimistic. when I googled it all I found was that it was not possible(as of now), but no other detail. I did stumble upon an old episode of myth busters in which they came to the conclusion that a car can run on hydrogen, but they were unable to provide enough hydrogen from their electrolysis setup, however, I noticed that the HHO generator created by king of random produces way more gas then theirs. so I wanted to know your opinion and knowledge on this matter and whether this can work or not.  



Also, an ideal method for detecting pranks about hydrogen as a fuel would be to see whether they call it brown`s gas or HHO. Please be careful.


Hello Ahtasham Ahmad Mohtashim. Car engines are not designed for using hydrogen as a fuel. It will probably not work anyway, and if it does, the engine will be damaged eventually. However, I will check it up and get back to you. If an engine were to be designed specifically for hydrogen, it just might work. I suggest you do a little more research. Be careful though, there are a lot of pranks related to oxyhydrogen from electrolysis. Compare pages with wikipedia to make sure that what you are reading is authentic.

Also, a hydrogen powered car is probably not good for a science fair project- there are inherent difficulties with using hydrogen as a fuel. It is difficult to store and to use. There are also some serious efficiency issues.

As the wikipedia page on ` hydrogen vehicle` says- Hydrogen fuel cells are relatively expensive to produce, as their designs require rare substances such as platinum as a catalyst,[55] In 2014, Toyota said it would introduce its Toyota Mirai in Japan for less than $70,000 in 2015.[12][56] Former European Parliament President Pat Cox estimates that Toyota will initially lose about $100,000 on each Mirai sold.[13]

Hydrogen does not come as a pre-existing source of energy like fossil fuels, but is first produced and then stored as a carrier,[61] much like a battery. A suggested benefit of large-scale deployment of hydrogen vehicles is that it could lead to decreased emissions of greenhouse gases and ozone precursors.[62] However, as of 2014, 95% of hydrogen is made from methane. It can be produced using renewable sources, but that is an expensive process.[3][63] Integrated wind-to-hydrogen (power to gas) plants, using electrolysis of water, are exploring technologies to deliver costs low enough, and quantities great enough, to compete with traditional energy sources.[64]

The challenges facing the use of hydrogen in vehicles include production, storage, transport and distribution. The well-to-wheel efficiency for hydrogen is less than 25%.[7][68][69][70] A study sponsored by the U.S. Department of Energy said in 2004 that the well-to-wheel efficiency of gasoline or diesel powered vehicles is even less.[71]

1. School stuff is to be done without our help and setup ;)
2. Being able to run an engine on hydrogen does not mean the engine will tolerate for more than a few minutes.
3. Despite other claims on the WWW it is neither feasable nor advised to produce the hydrogen you need "on the go".
