Quote This appears to be a genuine breakthrough:  Power generation from ambient humidity using protein nanowires end quote


Quote    As reported today in Nature, the laboratories of electrical engineer Jun Yao and microbiologist Derek Lovley at UMass Amherst have created a device they call an "Air-gen." or air-powered generator, with electrically conductive protein nanowires produced by the microbe Geobacter. The Air-gen connects electrodes to the protein nanowires in such a way that electrical current is generated from the water vapor naturally present in the atmosphere.

"We are literally making electricity out of thin air," says Yao. "The Air-gen generates clean energy 24/7." Lovely, who has advanced sustainable biology-based electronic materials over three decades, adds, "It's the most amazing and exciting application of protein nanowires yet."

The new technology developed in Yao's lab is non-polluting, renewable and low-cost. It can generate power even in areas with extremely low humidity such as the Sahara Desert. It has significant advantages over other forms of renewable energy including solar and wind, Lovley says, because unlike these other renewable energy sources, the Air-gen does not require sunlight or wind, and "it even works indoors."

The Air-gen device requires only a thin film of protein nanowires less than 10 microns thick, the researchers explain. The bottom of the film rests on an electrode, while a smaller electrode that covers only part of the nanowire film sits on top. The film adsorbs water vapor from the atmosphere. A combination of the electrical conductivity and surface chemistry of the protein nanowires, coupled with the fine pores between the nanowires within the film, establishes the conditions that generate an electrical current between the two electrodes.

The researchers say that the current generation of Air-gen devices are able to power small electronics, and they expect to bring the invention to commercial scale soon. Next steps they plan include developing a small Air-gen "patch" that can power electronic wearables such as health and fitness monitors and smart watches, which would eliminate the requirement for traditional batteries. They also hope to develop Air-gens to apply to cell phones to eliminate periodic charging.


 
Yao says, "The ultimate goal is to make large-scale systems. For example, the technology might be incorporated into wall paint that could help power your home. Or, we may develop stand-alone air-powered generators that supply electricity off the grid. Once we get to an industrial scale for wire production, I fully expect that we can make large systems that will make a major contribution to sustainable energy production."

Continuing to advance the practical biological capabilities of Geobacter, Lovley's lab recently developed a new microbial strain to more rapidly and inexpensively mass produce protein nanowires. "We turned E. coli into a protein nanowire factory," he says. "With this new scalable process, protein nanowire supply will no longer be a bottleneck to developing these applications."

The Air-gen discovery reflects an unusual interdisciplinary collaboration, they say. Lovley discovered the Geobacter microbe in the mud of the Potomac River more than 30 years ago. His lab later discovered its ability to produce electrically conductive protein nanowires. Before coming to UMass Amherst, Yao had worked for years at Harvard University, where he engineered electronic devices with silicon nanowires. They joined forces to see if useful electronic devices could be made with the protein nanowires harvested from Geobacter.

Xiaomeng Liu, a Ph.D. student in Yao's lab, was developing sensor devices when he noticed something unexpected. He recalls, "I saw that when the nanowires were contacted with electrodes in a specific way the devices generated a current. I found that that exposure to atmospheric humidity was essential and that protein nanowires adsorbed water, producing a voltage gradient across the device."

In addition to the Air-gen, Yao's laboratory has developed several other applications with the protein nanowires. "This is just the beginning of new era of protein-based electronic devices" said Yao.

I doubt we'll ever see that come to light.

There is a far better way than this

But remember, you having free energy=you cant be here for free energy. We can only talk of free energy.

Its a game silly, play by the rules.

This statement is BS

>>>> New Green Technology Generates Electricity ‘Out of Thin Air’ <<<<<

because it already exists all your doing is moving the charged particles  about.
when it's neutral pos and neg are balanced equal, to subtract energy all you need do is separate poss and neg and collect them ie separate the + from the - and store them.

Generating it is a big fat Lie !

Its power output is puny compared to the power of the sun engine.

Humiliated.

As I laugh, laugh, at these professors.

sigh...here I was thinking infant stages of manipulating Biology into "SCALABLE" and quite passive energy harvesting .
how it "do what it do" ?? may open other understanding ??

Some see this research as a path we are destined to travel....where we actually enter the realm of creators...?
Building biological machines that can run off of the surrounding environment ...

Tool ..you need to work less selfish and more selfless....making people beg for help is "selfish" helping those who ask for help is "selfless" [see the difference?
open source is Selfless ....it thrives there ,...our planet is open source ...our sun is open source ...air water etc etc ....

By having a closed system whereby a fluid is cooled by the venturi effect then energy 'collected' from ambient to restore equilibrium.

Aussiebattler,


That sounds quite plausible !


Even transfer back and forth between vessels (expandable) with venturi siphon (bringing in ambient air)
Is interesting!


We use to have an experimenter here who did some work there (Tinman)


Thx
Chet

PS EDIT  here is a wonderful open source FE engineer playing with a "cool" atmospheric manipulation idea

I already described those things.

A sun is this big, a sun is that big.

No time for noobie stupid step by step things you have to know these things.

The emperor says do this, and he expects you to do it. Hes not there to coach you, he could do it himself.
