One of the most interesting talks at AAAS is about a discovery that may ultimately give the much-vaunted hydrogen economy an opportunity. Daniel Nocera, Professor of Energy and Professor of Chemistry at MIT delivered a plenary lecture on a new catalyst produced in his research lab, one that gets inspiration from the photosynthetic pathways inside plant cells to break up body of water into H2 and O2, giving up the H2 to be utilized as fuel.
Fulfilling the human’s future energy need is going to require the sun, said by Nocera, and that is only going to occur if we can stock that energy for utilization when it is not beaming. Plants developed to take advantage of high-power chemical bonds, and the oil, gas, and coal we presently utilize is just stored sunlight (thru plants), even though concentrated. Hydrogen is the single practicable solution compared to batteries, capacitors, or mechanical storage systems like pumped-up water or compressed air when you consider energy density and the work from his research laboratory may help do that possible.

The other day I came across an article containing list of water powered calculators from around the world. they guy went to a great length in researching all the available product and made a decent list. My attention was specifically drawn towards how these so called green batteries work. I was disappointed to know that these products like clocks and calculators, that are being marketed as water powered devices are not in fact water powered and also they are not as green as they claim to be.
Here is how they explained it at ixibo.com
At last we arrived at the company that made all the above devices possible and promises more. 
None of above calculator would have existed if H20 battery was not invented/marketed by Tango Group. They are were the first one but not the only one to mass produce and market Replacement H2O cells in pack of 2. These little monsters have Minimum continuous life 1 year. More details about this little niche industry here
These so called water powered devices use H20 batteries, which are very similar to other batteries. All of them work on same principle. They generate electricity by eroding zinc or other metal. not green at all.
