‘Artificial leaf’ gains the ability to self-heal damage and produce energy from dirty water

Another innovative feature has been added to the world’s first practical “artificial leaf,” making the device even more suitable for providing people in developing countries and remote areas with electricity, scientists reported here today. It gives the leaf the ability to self-heal damage that occurs during production of energy.

Daniel G. Nocera, Ph.D., described the advance during the “Kavli Foundation Innovations in Chemistry Lecture” at the 245th National Meeting & Exposition of the American Chemical Society.

Nocera, leader of the research team, explained that the “leaf” mimics the ability of real leaves to produce energy from sunlight and water. The device, however, actually is a simple catalyst-coated wafer of silicon, rather than a complicated reproduction of the photosynthesis mechanism in real leaves. Dropped into a jar of water and exposed to sunlight, catalysts in the device break water down into its components, hydrogen and oxygen. Those gases bubble up and can be collected and used as fuel to produce electricity in fuel cells.

“Surprisingly, some of the catalysts we’ve developed for use in the artificial leaf device actually heal themselves,” Nocera said. “They are a kind of ‘living catalyst.’ This is an important innovation that eases one of the concerns about initial use of the leaf in developing countries and other remote areas.”

Nocera, who is the Patterson Rockwood Professor of Energy at Harvard University, explained that the artificial leaf likely would find its first uses in providing “personalized” electricity to individual homes in areas that lack traditional electric power generating stations and electric transmission lines. Less than one quart of drinking water, for instance, would be enough to provide about 100 watts of electricity 24 hours a day. Earlier versions of the leaf required pure water, because bacteria eventually formed biofilms on the leaf’s surface, shutting down production.

“Self-healing enables the artificial leaf to run on the impure, bacteria-contaminated water found in nature,” Nocera said. “We figured out a way to tweak the conditions so that part of the catalyst falls apart, denying bacteria the smooth surface needed to form a biofilm. Then the catalyst can heal and re-assemble.” …

Analysis Finds Monsanto’s GM Corn Nutritionally Dead, Highly Toxic

Is GMO corn nutritionally equivalent to non-GMO corn? Monsanto will tell you the answer is a big ‘yes’, but the real answer is absolutely not. And the simple reality is that they are continuing to get away with their blatant misinformation. In fact, a 2012 nutritional analysis of genetically modified corn found that not only is GM corn lacking in vitamins and nutrients when compared to non-GM corn, but the genetic creation also poses numerous health risks due to extreme toxicity.

With the recent passing of the Monsanto Protection Act, there is no question that mega corporations like Monsanto are able to wield enough power to even surpass that of the United States government. The new legislation provides Monsanto with a legal safeguard against federal courts striking down any pending review of dangerous GM crops. It is ironic to see the passing of such a bill in the face of continuous releases of GMO dangers.

…sounds like an interesting development. Working with electrically charged water droplets and wind to produce energy.  3 minute video below.

Invention of the day: A bladeless wind turbine

It may look like a giant airplane window strung with Venetian blinds, but this structure, designed by Dutch architecture firm Mecanoo and installed at the Delft University of Technology in March, is a model of a machine that would convert wind to energy without any moving parts.

Any mechanical moving parts, at least: The technology, developed by the Electrical Engineering, Mathematics and Computer Science faculty at Delft, uses the movement of electrically charged water droplets to generate power. How does this work? A handy video explains:
