Did you check liter per minute?

exactly what grade or type of alum. is that ?????

To tell you the truth, I have no idea where the hydrogen comes from in this reaction. I think its being released from the potassium hydroxide. No idea where the potassium ends up. The oxygen I think combines with the aluminum to form aluminum oxide. So it will be interesting to see if the KOH is consumed during the reaction. That should tell us where the hydrogen is coming from. I dont think its cracking the water. Water is lost to heat/steam in this reaction. I think. Let us know.

quite nicely done (: do you use a PWM?

i believe it was a mig welder adapted with a wire feed of aluminium on to a solid aluminium roller encased in the water which produced desired gas .bmw used it and then said the residue of oxide was a problem (what they meant was not at this time as we have a lot of oil companies to keep going)!

google "the cornish device" for an example of a device that was constructed to use this chemical reaction, along with a high voltage electrolytic reaction. it was a facinating device that is said to have powered a car. The fellow used aluminum wire fed into his reactor as needed. complex mechanism but interesting none the less.
You know, I am not quite sure. I think that every aluminum grade would work, also zinc and magnesium should do the same although I have not tried it.

Also, this little aluminum piece still creates lots of gas after about 24 hours. It has become a little less in size, the water level is lower now and there is lots of black aluminum oxide on the bottom of the glass jar :)

No, there is no PWM or any electricity involved. The KOH just "eats up" the aluminum, creating lots of hydrogen in the same time.
SmartScarecrow, I also looked up the Cornish device and am very grateful that you mentioned it, this is interesting. Although I am using a ittle different principle.
Thanks :)

To run a car from this gas would require costly and difficult conversion of the engine. But this could be used as a cheap booster to improve the gas mileage. At first we need to get an answer for following questions:
What happens to KOH? Is it also being consumed just as the water and aluminum? How much gas can be created with a certain amount of aluminum? How toxic is this gas?
I am not strong in chemistry :)
