Water to hydrogen or utilizing the properties of water as a source of energy is for me one of the most powerful deed humans have ever done.
"And, of course, for those of us to whom the water is a special attraction, this is heaven on earth." - Walter Cronkite
To continue on Thales' theory of all things finding their "original" in water, harnessing its energy is just a logical thing to do. No wonder, using the elements in water has no negative effects in the environment. It could even help us heal it as it has been severely abused.
There are several methods now on how to produce hydrogen on demand - hydrogen produced at the point of use.
And, nature for one has given as a clue - Photosynthesis. A lot of effort worldwide had been extended to imitate the process through the use of catalytic substances, and the classic electrolysis.
By photosynthesis it uses just the sunlight itself and bacteria combined.
*Solar Hydrogen is one example as an attempt to produce hydrogen on demand using Tandem Cell or nano scale structure - an advance solar panels that captures highest form of sunlight for electrolysis.
*Honda is making its way to producing homefueler or home fueling station using solar power for cars.
*Researchers at the University of California at Berkeley have engineered a strain of pond scum or Mutant Algae that could, with further refinements, produce vast amounts of hydrogen through photosynthesis.
Catalytic Substances used are Silicon, Boron, Aluminum, and other nano sized colloidal metals and some magnesium hydride slurry. Some combine magnesium, aluminum and stainless steel to produce hydrogen from water.
*Like, PowerAvenue Corp has patented a process to create a form of silicon from sand that reacts with water. They have combined this fuel cells that operates at low pressure and temperatures.
*Here's Rothman Technology which uses water, salt, and a claimed to be extremely inexpensive metal alloy. The process produces pure hydrogen, that burns without the need for external oxygen — and gives off zero carbon emission.
*Purdue University in West Lafayette, Ind. discovered the use of a catalyst based on metal rhenium called organosilane to produce hydrogen.
*AirGen Corporation technology involves a process of chemical reaction through a mixture of water, metals and nanosized colloidal metal using a thermal and/or electric energy source.
One good thing about the use of catalytic materials is that they can be regenerated after use into its original forms, like Boron and Aluminum.
Water to hydrogen, all those technologies and processes are here because of the environment loving people's attempt to reverse what fossil fuel have done to our lives today.
We are indeed finding our "original" and going back to it.
Try the hydrogen car kits to convert your cars from fossil dependent to HHO or basically saying WATER.
At the end of the day, Making-Hydrogen.com is about how to create hydrogen from solar power to bacteria! What is the coolest way you have discovered in making hydrogen?
