[edit] Someone has done some good work on this page.

Well organized! That's what a Table of Contents should look like ideally. Maybe a Conclusion section would be good. Just a few sentences summing it up. KarenAnn 00:18, 5 June 2006 (UTC)

[edit] "Water purification"

Water purification is not a method of hydrogen production. I've deleted again. --Pjacobi 18:03, 5 September 2006 (UTC) I fixed the category text:

The following articles relate to or are required for the production of hydrogen.. reg. Mion 20:44, 5 September 2006 (UTC)

And you have to purify the water.Mion 20:44, 5 September 2006 (UTC)

"Water purification" was listwed as a method of hydrogen production. This was and is still wrong. You cannot produce hydrogen by purifying water. Mion I must severely doubt your qualification for the project you try to do here. --Pjacobi 07:12, 6 September 2006 (UTC)

I didn.t say it is a method, but if you talk about hydrogen production from water the first step is the purification of water.Mion 08:18, 6 September 2006 (UTC)

The first step in most chemical synthesis is purification of the starting materials. But it's rarely mentioned. And it's not always necessary. Hydrogen can be made from seawater. In fact, in electrolysis, it's necessary to use impure water. Give it up. SBHarris 08:36, 6 September 2006 (UTC)

yes, for conductivity, but certain elements have to be removed, i think its better to include when waterpurification is used and when not, and where is the section about hydrogen purification ? Mion 08:52, 6 September 2006 (UTC)

The waterpurification should be under electrolysis tp prevent the misconception that it is a method. Mion 08:57, 6 September 2006 (UTC)

[edit] argon

I have heard of using surface uranium for extraction. I am sorry but i dont remember where, but the idea was that if you found an area with high amounts of radon, you would be able to extract hydrogen from water due to nuclear decay. —Preceding unsigned comment added by 74.78.78.201 (talk) 02:18, 18 October 2007 (UTC)

[edit] Aluminum-Gallium pellets produce hydrogen from water on contact

As I already mentioned in Talk:Hydrogen_economy, Jerry Woodall, a researcher in Purdue Discovery Park, has made an interesting discovery. The article describes a chemical process in which water reacts with aluminum, the latter effectively stripping water molecules of their oxygen and freeing hydrogen. The gallium prevents formation of aluminum oxide film which would stop the continuous reaction. The reaction takes place until either aluminum or water runs out. More informative description of the process can be found in a Flash-based presentation Woodall has compiled. Does anyone have more information and any thoughts if this should be included in the article? --Khokkanen 19:43, 1 September 2007 (UTC)

[edit] John Kanzius

The folks discussing John Kanzius are proposing that content be merged into Hydrogen_production.

The problem here is that it is not clear what Kanzius is claiming.

Is he or is he not claiming that he gets more energy out than the RF input?

If yes: then it appears a water as fuel proposal

If no: then he is apparently claming a highly efficient method of producing hydrogen.

Which is it?

Kaznius himself is not making any public comments, he does not even have a web site. The statements reported and attributed to him have been contradictory.

Meanwhile, his strongest supporter so far, Dr. Rustum Roy, states (as of 13th Sept 2007):

"He has not made any attempt as far as we know to obtain the data regarding the energy balance between input and output." http://www.rustumroy.com/response_to_email.htm

The problem here is complete absence of data on the input and output energy numbers for the process. It is puzzling as to why this is being kept so secret..... I can understand secrecy about HOW it is done, but secrecy as to WHAT has been done makes no sense. Charles 15:29, 16 September 2007 (UTC)

I oppose the merge. See Talk:John_Kanzius#Problem_with_merge_proposal ≈ jossi ≈ (talk) 16:16, 16 September 2007 (UTC)

[edit] "Nanoparticles could make hydrogen cheaper than gasoline"

From the article:

"the coatings can be used to retrofit existing electrolysers to increase their efficiency to 85 percent--exceeding the Department of Energy's goal for 2010 by 10 percent"
"Instead of switching 170,000 gas stations over to hydrogen, using our electrodes could enable consumers to make their own hydrogen, either in the garage or right on the vehicle"
