I have a question about the article written by Isaac Asimov in 1987 that was published in the Los Angeles Times. It said
For instance, coal, oil, and gas all contain hydrogen atoms and you can obtain pure hydrogen from them, but it takes some energy to do this. You have to burn some oil to get hydrogen out of other oil and in this way, you end up with less fuel than you started with.
Is there anything that contains hydrogen that is not a fuel? Yes-there is water, the weight of which is one-eighth hydrogen. The only trouble is that ripping the hydrogen out of water takes energy.
(title: Quest for Fuel an Ongoing Objective, LA times (1987)),
Should I interpret this as meaning 'Yes-there is water, the weight of which is one-eighth of hydrogen'?
When you say that A is one-eighth of B, that means A=1/8×B, right? However, does this mean that water is lighter than hydrogen? Even though water is actually heavier than hydrogen.
