Talk:Hydrogen

A separate article on hydrogen energy might be better, but, it is in this context that people now most often hear hydrogen mentioned. So it's quite reasonable to leave it in this article. Likewise mention of carbon and ozone and nitrogen is also almost always in an atmosphere context these days in the news. If that changes, hell, we change the articles, big deal.

It's very important to note the hydrogen infrastructure issue and power grid analogy. A lot of people are under the totally wrong impression that hydrogen as used in fuel cells is in fact a fuel that is "mined" from the ground like fossil fuel and which actually contains the energy, rather than having to be created from another electricity source. This is only true if one has fusion. Which we don't.

Didn't mention cold fusion or aneutronic fusion in general either here. There've been many attempts, all failed or suppressed (you tell me which!).

Why do you mention the part about Iceland? Huh?--Filll 13:57, 17 November 2006 (UTC)

Hydrogen power grid

This whole section needs to be rewritten. It appears to be an opinion with concepts and ideas from a point of view. There is no reference or proof provided. It also asks a rhetorical question in an unnecessarily colloquial way. 203.12.139.104 (talk) 02:37, 3 June 2008 (UTC)

Changes to organization, diction

I made a few changes to the diction used to simplify the language and use fewer pronouns to help clarify what the author is referring to. The biggest changes I made were to the organization so that there is a clearer flow of information (i.e. introduction --> hydrogen in nature --> uses of hydrogen: example, example, example). I'd also like to add more references to the work that people have already done. Thanks! Jia.liu (talk) 03:22, 13 April 2009 (UTC)

Greek Word for Water??

I'm not sure the Greek word for water is correct.. and the pronunciation key seems to say "You Stupid"?? Is that just me? 99.24.222.27 (talk) 19:51, 18 May 2010 (UTC)

Hah, no it's not just you. It's old vandalism. Fixed now, thanks. J.delanoy ^talk_changes 00:13, 19 May 2010 (UTC)

Something needs clarified (or simplifed) or be removed

"Hydrogen did not begin to form a second after the Big Bang. These hydrogens did not have any neutrons or electrons. The first neutral hydrogen with an electron would not form until 380,000 years later during the ...".--Not my cup of tea, for now. 80.67.37.2 (talk) 12:02, 21 October 2024 (UTC)

I am not entirely sure what you are referring to. You said in your edit summary that hydrogens did not form until 380,000 years after the big bang, and that hydrogens did not form a second after the big bang, and provided a source that proved your claim. Your claim is not true. Proton atoms(or, positively charged hydrogen) formed within a second of the universe being formed. Your number of 380,000 years is actually from the recombination epoch when electrons and neutrons join hydrogen. Your source even makes this distinction(although it did say that the time for protons to form was longer than what some other sources say, but that is another topic).

I reverted this edit because it is clearly wrong and non-controversial.

Please tell me if I am misunderstanding, your stance, however. Thanks, MrMeAndMrMe_Talk 02:21, 1 November 2024 (UTC

One next step could be for this talk page to say, what En-wiki is saying and/or present a relevant quote from the source. 2001:2020:323:F662:D874:A0F2:5544:9A23 (talk) 06:11, 1 November 2024 (UTC)

Maybe one can say something like "The first neutral hydrogen with an electron would not form until 380,000 years after big bang. However, protons (or positively charged hydrogen atoms were created ... a second.)"--Please go ahead and make that change if it sort of sounds okay.--Note: positively charged hydrogen atom is maybe not a simple concept - unlike (arguably) a 'regular' hydrogen atom.--We should not be moving goal post (of school science for fifth graders), by saying that there is one type of hydrogen, and then there is a hydrogen that has electrons.--If this post is regarded as helpful, then fine. 2001:2020:323:F662:D874:A0F2:5544:9A23 (talk) 06:24, 1 November 2024 (UTC)
