Quote: hey im new here but u obviously know what your talking about i recommend not trying to light hydrogen with a match (personal experience) hydrogen has a octane of 130 where petrol is only around 85-90 so yeah its gonna go boom faster ive made a fully functioning wet cell generator it works beatifully but its not all that effiecient so im now making a dry cell in a couple of months im going to get a cheap datto and run hydrogen through it yer i was going to do it but lack of space in the engine bay, and other issues prevented me, plus to be honest im sure as we covered before the 4L engine is just to big to run with HHO effectively. if i had the money/space to throw at a project, my car of choice would probably be pretty similar to your choice on the datto. my wet cell disintegrated when i used NaOH (55% drain cleaner) as my catalyst; it ate up my tin foil plates  . if 316L stainless steal wasn't so friken expensive i would make a generator for sh!ts and gigs. but then again i was looking at making up a design with over 30 plates!!!!!!!! i worked out the cost to be around over $100 just in plates.

yeah i know what your talking about my HHO generator (wetcell) is awesome it runs but havent tested it on the datto yet still waiting to find one sorry but soon as i do im making 3 drycell generators around 20 plates in each with a bigger altinator in the datto as you say for s**t and gigs lol
if you want i can post some pictures of my HHO (first ever made By me) so if ya want just say so (i used stainless steel from around the place also ive heard platinum plates are better for it but more costly) |

just don't forget that you need to produce allot of HHO gas to effectively lower an engines petrol consumption. and usually a lot of gas requires a lot of power, which in turn puts more strain on your engine, so don't be shocked with the fuel consumption doesn't drop like some of the yanks say it will.
for example, lets say a 1.5L engine is being powered, and we can assume it has a 90% air volume efficiency. at 1000rpm that's 1350L of air sucked in per minute. (unless Ive done my maths wrong). i remember skimming over somewhere that a ratio of air:HHO is 34:1 to provide effective HHO running. so in other words you need to produce just under 40L of HHO per minute, to make the car more efficient at 1000rpm. # im not 100% sure on that ratio as their is actually less energy in HHO then in petrol, may be wrong but i think thats got to do with my the octane rating is so high. by the way, fiat 500 is a 2 cylinder 500cc engine, some modification would have to be done to fit an alternator but that's the smallest engine i can think of placed in a car. soooooo in other words for the ultimate sh!ts and giggles project, try to help power the cells with other sources of energy  solar panel roof anyone??

hmmmmm sounds a bit hard to swallow. Lets see some vids of it actually running on a car...(it'll probably end up on youtube with all the perpetual motion machines...)

i'd hate to see a backfire with this type of setup lol bye bye airbox.

Quote: i'd hate to see a backfire with this type of setup lol bye bye airbox. this is why HHO set ups use a bubbler and then a 1 way valve to eliminate backfires. as a back fire in a air box is one thing, but a back fire into a HHO generator equals massive damage. as i said in one of the previous post theoretically about 40L of HHO per minute is requires for running a 1.5L engine at 1000rpm... a relatively powerful HHO generator pushes only 3-5L per minute of HHO. so if someone was to do this it would be more so for sh!ts and giggles rather then actually increasing their fuel consumption. so please dont see me as a person that falls easily for these scams, i am merrily a uni science student

i dont really care much for the maths side but i intend to put alot of money into it 2 make this car run im making my drycell hho generator soon so hopefully its more efficient then the wetcell like everyone says they are. but im putting a 30watt altenator in the datto for maximum input with 3 banks of batteries in the boot and the drycells under the bottet because they got alot of space underthere(hopefully 3 or 4 drycells)
 lets see how this goes |

yeah its pritty fun to put bottles of hydrogen on a fire (done it myself) but becareful im making my new ones around 15 cm by 15cm im hoping with o rings and so on but ill defidently post some photoes of the progress of you guys want it plus dattos are reliable so im going to run the 30w altinator off of it and improve all the wiring in the car so im going to see how it goes and if it run on hyrogen ill pput the plans up and tally up how much it costed.

theirs a type of rubber you can buy, cant remember the name of it but Clark rubber sell it in sheets, it starts with N and its not natural rubber. Use that to make a frame instead of a O-ring, as you'll get more surface area. where are you getting your plates from and are you using 316L grade SS.
photos yes please and what size engine is the datto, as i said you need allot of gas to to lower your fuel consumption in a small engine at low revs.

i dont know what size the datto is but im pritty sure its a 1.6 or something (unsure) but ill try that rubber from clark rubber see if its worth the money since i just got a tonne of 0 rings hanging around
and the pictures of the car or the wetcell gen? |

Ive heard that Neoprene Rubber is the best to use as it doesn't corrode like normal rubber will.
pics of the dry cell when you build it, also where are you planing on getting your plates from, as im trying to build a small dry cell but still dont want to spend $100+ in stainless steel alone, as 316L is one of the more expensive grades.

i got no idea where im getting the steal but i got so many projects on the go im spending over a grand this week on projects fun i think yes but im going to price some steal like that. im thinking something like bunnings or some steel fabricator i dont know

bunnings will be pretty expensive (about $46 a sheet cant remember distentions but its 0.5 thick), for me to muck around it will cost over 100 bucks in steel alone. to make a small generator to my linking it will set me back over 150 just to have some fun.
