As long as you think that "hydrogen power" is an energy source you will not be able to fix the world.

Karama Neal

So what can I do to fix the world? Visit sowhatcanido.blogspot.com for my suggestions. Enjoy!

You should add Don Kosloff's Bullshit (DKB) to your list of alternative energy resources. It burns rather quickly, is readily available in large quantities, and has no other known uses.

Don Kosloff

Well Mr. Wizard, since you assert that my comment was BS, perhaps you should explain how hydgrogen can be a source (as opposed to a transfer or storage tool) of energy. For example, you could tell us where the hydrogen mines, hydrogen wells and hydrogen orchards are.

By the way, I am sorry that I actually don't have even a tiny supply of DKB. But real BS is actually a greater source of energy than hydrogen. Many people dry it out in the sun and use it in their cooking stoves. The real Legend of Cow Patty.

Are you kidding? Contrary to what you may believe, the paragraph on water electrolysis that you read in your Chemistry 101 book was not the last word on the subject of hydrogen fuels. Remarkably, in the time since that esteemed primer was published, intrepid scientists have been able to come up with a dozen ways to harvest free hydrogen from sustainable precursors, including futuristic plans to tap deep sea hydrothermal vents and possible metal hydride veins, as well as more practical and immediately implementable methods such as the mass cultivation of genetically enhanced hydrogenosomic bacteria and algae strains. Try picking up a science journal every once in a while Don, you’ll be amazed at what intelligent people are doing these days.

"Pie in the sky by and by", as the old song goes. A possible metal hydride is not a source of anything other than dreams. How many of the alleged dozens of sources of hydrogen have produced any usable hydrogen that has produced energy in excess of the energy needed to produce the hydrogen? How do you get free hydrogen from a metal hydride without any energy costs?

If the bacteria farts are indeed "practical and immediately implementable" who is using them to produce hydrogen, a valuable industrial commodity, even without a hydrogen energy infrastructure. The same people who are harvesting the methane in cow farts?

Mister Wizard

“How many of the alleged dozens of sources of hydrogen have produced any usable hydrogen that has produced energy in excess of the energy needed to produce the hydrogen?”

All of them. Hydrothermal vents produce molecular hydrogen spontaneously through a process of high temperature geothermal electrolysis and/or possibly hydrogen release from exposed metal hydride veins. Hydrogenosome containing bacteria feed off organic waste matter and/or waste emissions, in the absence of light and oxygen, and with the proper catabolic enzyme gene inserts can be made to feed off any practically any refuse material. Hydrogen creating algae produce hydrogen using a number of different photochemical mechanisms. They require a slightly more nutritious food stock than bacteria, as well as a source of sunlight, but, other than, they are also a self-sustaining source of hydrogen. Further study of hydrogenosomic bacteria and hydrogen creating algae will allow molecular biologists to isolate and genetically enhance the hydrogen producing mechanisms of both of these organisms. Additionally there are at least a hundred different thermochemical reaction cycles that generate hydrogen from water and recyclable inorganic catalysts. Most of them require high temperatures to operate effectively, but one of the newer catalyst mixtures is powered by solar thermal mirrors and operates at a significantly lower ambient temperature.

Your understanding of the concept of energy balance is a bit flawed. Gasoline is a highly refined, processed, and non-renewable industrial product that is, in almost every case, produced with a negative energy balance. Some alternative fuels currently have a greater negative energy balance than gasoline, but many do not, and there are a number of alternative energy combinations, like the ethanol and biomass economy of Brazil, that operate with a positive energy balance.

During the course of this discussion I’ve also noticed that you never make a distinction between renewable and non-renewable energy resources, which, I believe, further reveals your lack of understanding of this important subject.

“How do you get free hydrogen from a metal hydride without any energy costs?”

The metal hydrides to which I am refering are interstitial metal hydrides, that, unlike crystalline compounds, do not require electrochemical decomposition to free their constituent hydrogen, but instead consist of institial matrices within which molecular hydrogen is quasi-suspended by the electronic forces of a metal hydride lattice. The rate of molecular hydrogen release from a interstitial metal hydride matrix is a function of its metallic composition as well as its ambient temperature. The exact metallic composition of naturally occurring metal hydrides will vary, but they are expected to contain a wide variety of exotic alloys, some of which are capable of releasing 1000 time their volume’s worth of molecular hydrogen at room temperature.

“If the bacteria farts are indeed "practical and immediately implementable" who is using them to produce hydrogen, a valuable industrial commodity, even without a hydrogen energy infrastructure.”

This is a very active and wide ranging field of research. Let me once again encourage you to read, or have someone read to you, an actual science periodical instead of a pamphlet from OPEC.

“The same people who are harvesting the methane in cow farts?

With all due respect to the agribusiness community, it’s actually more efficient to grow methanogen bacteria in a controlled anaerobic environment.

Also, most people would probably use a breathing analogy to describe bacteria and algae respiration, but your continued reference to flatulence is also understandable given the close proximity of your head to your ass.

Don Kosloff

You used a lot of words to avoid the questions. There is a significant difference between research and production. What is your source for your information on the negative energy balance of gasoline?

Nice blog!and interesting story above.
