Hydrogen from Aluminum Demonstration Video

The actual process: gallium and aluminum combining, add water. stir - bubbles of hydrogen with only white aluminum oxide. as demonstrated by John Woodall - Jerry M. Woodall, National Medal of Technology Laureate, Distinguished Professor of School of Electrical and Computer Engineering, Purdue University, West Lafayette, IN http://hydrogen.ecn.purdue.edu/

[YesAndWhat1]

hey i was wondering if you have a video for the purification of water and generation of electricity through this method? i read the article but would like to see it happen

[dadeo1111]

@YesAndWhat1 - sorry, no.

[ogsterduck1]

why do they call it an experiment if its already been done, why not call it an example

[dadeo1111]

Semantics?

[Opinionator52]

This is interesting, but when we can't get a reply to posted questions what good is it?

[dadeo1111]

All the info I have is in the description. This isn't my video, it's Dr. Jerry M. Woodall's, who is Professor of School of Electrical and Computer Engineering, Purdue University in West Lafayette, Indiana. Please contact him about specifics on this as I'm just a messenger for this very worth endeavor. Thanks. -D

Aluminum is actually quite reactive, and reacts with air and water. however, if forms a thin layer of aluminum oxide, which blocks further oxidation. the liquid gallium keeps the aluminum oxide off the aluminum so that more water can react with it.

Yes, but you end up with sodium aluminate and that's the end of that. With Ga-Al, you end up with Ga and Al2O3 and resuse the Ga and the Al2O3 goes back to the factory.

@livnlarge1980 Electrolysis "uses grid electricity which is produced by burning coal" and therefore it is not a "green" solution.  The purpose of this is to have a solution that is more environmentally friendly.

[livnlarge1980]

and what is the purpose of this?? There are thousands of people on youtube making hydrogen generators via electrolysis using stainless steel, aluminum and copper. Does this happen to be more cost advantageous compared to the other examples.

[spotlightman1234]

must have been very expensive!!

[Video85Man]

thats nice!!

kool you just undid the work of stars which help make our planet and youself xD

@AHW214 You best put some fine grain of Alu into the liquid Gallium, stir. Although Alu needs 660 degrees Celsius to melt, the Gallium will nonetheless penetrate it and build an alloy. Gallium has the tendency to penetrate other metals.

The alloy (let's say 50:50) is rather stabile in the air, but inside water the alu will oxidate(to al2o3) by taking 1 Oxide Atom from Water (h2o), leaving 2 free hydrogen Atoms back. So Hydrogen is the only "fumes", not toxic, but higly flammable.

Actually the gallium-alluminium alloy is a pretty good energy storage medium since the desintegration, as shown here, releases almost as much as energy (hydrogen that could power an engine directly) as it is required to turn aluminium-oxidxe back into aluminium. As fas as I see it's a much better solution than hydrogen tanks that may explode, just like some batteries that are used in electrical cars.

[AHW214]

Could I make a alloy that would react with water to make hydrogen by smearing liquid gallium on aluminum foil? Also what are the products of the water and aluminum reaction and how should I dispose of them. Are any toxic fumes given off?
