Hydrogen fuel cells begin to show off in the world of competitive racing

22. I don't give a shit about efficiency of oil

Because oil, coal, and other non-carbon neutral sources are destroying our climate it doesn't matter how efficient they are. They have to go no matter what their efficiency. So fuck oil, etc. They are irrelevant to the discussion.

But when calculating the cost of carbon neutral energy futures one cannot ignore the fact that there are zero sources of molecular hydrogen on our planet. All hydrogen is made by electro-chemical processes, presumably by hydrolysis of water which always takes more energy than the subsequent burning of hydrogen gives back.

What is wrong with people in this thread? Are you all that ignorant of basic physics that you cannot understand what I have written here? Or am I that bad at communicating?

What do you think I am trying to say? That hydrogen is bad? No! That it isn't useful? No! I am only saying that it isn't a fucking energy source since it takes more energy to make it than it generates by burning it. But it IS a great energy storage medium assuming we can do that efficiently.

We need to put billions of dollars into research on energy, including solar, wind, yada-yada, and hydrogen.
