Hydrogen appliances, what I would like to expect here are actual home and personal appliances that are powered by hydrogen. Like Angstrom Power's hydrogen-powered Motoslvr cell phones. Their prototype is claimed to last twice as long between refueling than phones powered with lithium ion batteries. The fuel cell were made so small to fit comfortably inside the phone.
Or maybe I would like to see in the near future a refrigerator and other home appliances powered by hydrogen through an Artificial Inorganic Leaf (AIL)-a "biophotolysis" technology.
Here's something intriguing video on Fuel Cell Charger.
My question in this video is that, I don't know what the cartridge is made of and how is it able to electrolyze the water that is filled in it. My suspicion is that it is battery operated, and I don't know the conversion efficiency. But nevertheless, it was able to demonstrate an innovation that could be enhanced.
An article from USNews Science features Timothy Dolan, an experimenter who calls himself "a developer of technology". He lives on Chestnut Hill Road in Trumbull, Connecticut . For the last five years, he has been using hydrogen appliances such as gas range, and even operate a lawn mower and a portable generator. He said that the only thing wasted in doing so was sunlight.
Having his electrolysis system takes place in an enclosed tank, he said that the hydrogen gas "compresses itself — I stop it at 2,000 psi (pounds per square inch)."He further said that "it's simply a matter of making the gas orifices a little smaller to compensate for the smaller molecular weight of hydrogen as opposed to natural gas."
He said that "fear" made us resist in using hydrogen.
Hydrogen as source of energy holds much promise for a future in which everyone can have energy that is efficient and clean and that it can be produced home-based. A very empowering and liberating feat for the humanity.
