I hydrogen by mimicking photosynthesis

As many know, photosynthesis is one of the activities any sort of vegetable Kingdom can generate their own food, i.e. energy, something that if took it to the demands of electric power, is precisely what is being sought from the earliest times.

Focusing on this concept, it has been announced that a new technology that plan to use a very similar to the photosynthesis system to create electricity using hydrogen is currently in full development.

As many know, one of the ways to obtain this raw is "breaking" the water molecule, although also it may be subjected to other processes to generate new hydrocarbon resembling a fossil, fuel behaviour although of course, should participation oxygen in this reaction.

In plants, acts also as an oxidizing agent, but it is quickly released in breathing, absorbing carbon dioxide, which would have to work for increased performance (for the moment, the structure of the hydrogen cell degrades)

As if this out, this would be combined also with the use of solar energy, applying directly using a blue light technology, creating a highly efficient energy conversion system.

At the moment it's all in development and is no more than a project, though it is advancing by leaps and expected results are too optimistic.

Artificial leaf that Imitates Photosynthesis - Solar energy

Now we have spoken above of various scientific projects to develop artificial leaves that mimic photosynthesis and they take advantage of the solar energy to generate renewable energy. In this case, we will tell of further progress in this regard with a feature that distinguishes it from other similar: (its components nickel and cobalt) make economically viable, to the point that there are potentially interested in manufacturing companies.

In the Edition number 241 of the national meeting of the American Chemical Society has made the formal announcement of this scientific breakthrough. He is - as I anticipated - an"artificial leafthat could be used to generate energy enough for the daily maintenance of the energy needs of all a home, something is expected to apply in those areas without coverage of the power grid in developing countries.


This advanced solar cell has a dimension similar to a tile and is composed of silicon, electronic compounds and catalytic converters.


 Instead of directly convert sunlight into energy (as do the photovoltaic solar cells), follows a different process. Similar to a "natural" sheet using water to imitate the process of photosynthesis, by placing in a container with water under the ray of the Sun "artificial leaf" can be divided the H2O molecule into oxygen and hydrogen, collecting these gases in a cell of fuel.
