Air-gen Protein Nanowire Generator delivers clean energy by harvesting ambient humidity via Geobacter-derived conductive nanowires, generating continuous hydrovoltaic electricity through moisture gradients, electrodes, and proton diffusion for sustainable, low-waste power in diverse climates.

Key Points

A device using Geobacter protein nanowires to harvest humidity, producing continuous DC power via proton diffusion.

✅ 7 micrometer film between electrodes adsorbs water vapor.

✅ Output: ~0.5 V, 17 uA/cm2; stack units to scale power.

✅ Geobacter optimized via engineered E. coli for mass nanowires.

They found it buried in the muddy shores of the Potomac River more than three decades ago: a strange "sediment organism" that could do things nobody had ever seen before in bacteria.

This unusual microbe, belonging to the Geobacter genus, was first noted for its ability to produce magnetite in the absence of oxygen, but with time scientists found it could make other things too, like bacterial nanowires that conduct electricity.

For years, researchers have been trying to figure out ways to usefully exploit that natural gift, and they might have just hit pay-dirt with a device they're calling the Air-gen. According to the team, their device can create electricity out of… well, almost nothing, similar to power from falling snow reported elsewhere.

"We are literally making electricity out of thin air," says electrical engineer Jun Yao from the University of Massachusetts Amherst. "The Air-gen generates clean energy 24/7."

The claim may sound like an overstatement, but a new study by Yao and his team describes how the air-powered generator can indeed create electricity with nothing but the presence of air around it. It's all thanks to the electrically conductive protein nanowires produced by Geobacter (G. sulfurreducens, in this instance).

The Air-gen consists of a thin film of the protein nanowires measuring just 7 micrometres thick, positioned between two electrodes, referencing advances in near light-speed conduction in materials science, but also exposed to the air.

Because of that exposure, the nanowire film is able to adsorb water vapour that exists in the atmosphere, offering a contrast to legacy hydropower models, enabling the device to generate a continuous electrical current conducted between the two electrodes.

The team says the charge is likely created by a moisture gradient that creates a diffusion of protons in the nanowire material.

"This charge diffusion is expected to induce a counterbalancing electrical field or potential analogous to the resting membrane potential in biological systems," the authors explain in their study.

"A maintained moisture gradient, which is fundamentally different to anything seen in previous systems, explains the continuous voltage output from our nanowire device."

The discovery was made almost by accident, when Yao noticed devices he was experimenting with were conducting electricity seemingly all by themselves.

"I saw that when the nanowires were contacted with electrodes in a specific way the devices generated a current," Yao says.

"I found that exposure to atmospheric humidity was essential and that protein nanowires adsorbed water, producing a voltage gradient across the device."

Previous research has demonstrated hydrovoltaic power generation using other kinds of nanomaterials – such as graphene-based systems now under study – but those attempts have largely produced only short bursts of electricity, lasting perhaps only seconds.

By contrast, the Air-gen produces a sustained voltage of around 0.5 volts, with a current density of about 17 microamperes per square centimetre, and complementary fuel cell solutions can help keep batteries energized, with a current density of about 17 microamperes per square centimetre. That's not much energy, but the team says that connecting multiple devices could generate enough power to charge small devices like smartphones and other personal electronics – concepts akin to virtual power plants that aggregate distributed resources – all with no waste, and using nothing but ambient humidity (even in regions as dry as the Sahara Desert).

"The ultimate goal is to make large-scale systems," Yao says, explaining that future efforts could use the technology to power homes via nanowire incorporated into wall paint, supported by energy storage for microgrids to balance supply and demand.

"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."

If there is a hold-up to realising this seemingly incredible potential, it's the limited amount of nanowire G. sulfurreducens produces.

Related research by one of the team – microbiologist Derek Lovley, who first identified Geobacter microbes back in the 1980s – could have a fix for that: genetically engineering other bugs, like E. coli, to perform the same trick in massive supplies.

"We turned E. coli into a protein nanowire factory," Lovley says.

"With this new scalable process, protein nanowire supply will no longer be a bottleneck to developing these applications."

EU Renewable Power Overtakes Fossil Fuels, reflecting a greener energy mix as wind, solar, and hydro expand, cutting CO2 emissions and curbing coal while negative prices rise amid pandemic-driven demand drops.

Key Points

A milestone as renewables surpass fossil power in the EU, driven by wind, solar, hydro growth and pandemic demand.

✅ 40% renewables vs 34% fossil in H1 across 27 EU states

✅ Wind, solar, hydro rose; coal generation fell 32% year-on-year

✅ Lower demand, carbon prices, grid priority boosted clean output

Renewable power for the first time contributed a bigger share in the European generation mix than fossil fuels, as described in Europe's green surge as the fallout from the pandemic cut energy demand.

About 40 percent of the electricity in the first half in the 27 EU countries came from renewable sources, exceeding the global renewables share reported elsewhere, compared with 34 percent from plants burning fossil fuels, according to environmental group Ember in London. As a result, carbon dioxide emissions from the power sector fell 23 percent.

The rise is significant and encouraging for law makers as Europe prepares to spend billions of euros to recover from the virus, with wind power investments underscoring the momentum, and set the bloc on track to neutralize its carbon footprint by the middle of the century.

“This marks a symbolic moment ​in the transition of Europe’s electricity sector,” said Dave Jones, an electricity analyst at Ember. “For countries like Poland and Czech Republic grappling with how to get off coal, there is now a clear way out.”

While power demand slumped, output from wind and solar farms increased, reflecting global wind and solar gains, because more plants came online in breezy and sunny weather. At the same time, wet conditions boosted hydro power in Iberia and the Nordic markets.

Those conditions helped renewables become a rare bright spot throughout the economic tumult this year. In many areas, renewable sources of electricity have priority to the grid, meaning they could keep growing even as demand shrank and other power plants were turned off.

Electricity demand in the EU fell 7 percent overall. Fossil-fuel power generation plunged 18 percent in the first half compared with a year earlier. Renewable generation grew by 11 percent, according to Ember.

Coal was by far the biggest loser in 2020. It’s one of the most-polluting sources of power and its share is slumping in Europe as the price of carbon increases, with renewables surpassing coal in the US illustrating the broader shift, and governments move to cut emissions. Power from coal fell 32 percent across the EU.

Despite the economics, the decision to shut off coal for good will come down to political agreements between producers and governments, while reducing reliance on Russian energy reshapes policy debates.

One consequence of the jump in renewables is that negative prices have increased, as solar is reshaping prices in Northern Europe in similar ways. On particularly windy or sunny days when there isn’t much demand, the grid can be flooded with power. That’s leading wind farms to be shut off and customers to be paid to consume electricity.

Georgia Cities Clean Energy IRP Coalition unites Savannah, Atlanta, Decatur, and Athens-Clarke to shape Georgia Power's Integrated Resource Plan, accelerating renewables, energy efficiency, community solar, and coal retirements through Georgia Public Service Commission hearings.

Key Points

Georgia cities working to steer Georgia Power's IRP toward renewables, energy efficiency, and community solar.

✅ Targets coal retirements and doubling renewables by 2035

✅ Advocates data access, transparency, and energy efficiency

✅ Seeks affordable community solar options for low-income customers

Savannah is among several Georgia cities that have led the charge forward in recent years to push for clean energy. Now, several of the state's largest municipalities are banding together to demand action from Georgia's largest energy provider.

Hearings regarding Georgia Power's Integrated Resource Plan (IRP) happen every three years, but this year for the first time the cities of Savannah, Decatur, Atlanta and Athens-Clarke and DeKalb counties were at the table.

"It's pretty unprecedented. It's such an important opportunity to get to represent ourselves and our citizens," said City of Savannah Energy Analyst Alicia Brown, the Savannah representative for the Georgia Coalition for Local Governments.

The IRP, which essentially maps out how the company will use its various forms of energy over the next 20 years was filed with the Georgia Public Service Commission (GPSC) in January, the 200-page IRP outlines Georgia Power's plans to shutter nearly all Georgia Power-controlled coal units, similar to Tucson Electric Power's coal exit timelines elsewhere, which could begin later this year.

The company is also planning to double its renewable energy generation by 2035. The IRP also outlines plans for several programs, including an Income-Qualified Community Solar Pilot, reflecting momentum for community energy programs in other states as well.

During the hearings the coalition, alongside the other groups, had the ability to question Georgia Power officials about the plan to include the proposed increase per kilowatt for the company's Simple Solar program, Behind-the-Meter Solar program study and various other components, amid debates over solar strategy in the South that could impact lower income customers.

"The established and open IRP process is central to effective, long-term energy planning in Georgia and is part of our commitment to 2.7 million customers to deliver clean, safe, reliable and affordable energy. In continuing our longstanding relationship with the City of Savannah, we welcome their interest and participation in the IRP process," John Kraft, Georgia Power spokesman said in an email.

Brown said the coalition's areas of interest fall into three categories: energy efficiency and demand response, data access and transparency and renewable energy for citizens as well as the governments in the coalition.

"We have these renewable goals and just the way the current regulations are set, the way the current laws are on the books, and developments like consumer choice in California show how policy shifts can reshape utility markets, it's very challenging for us to meet those renewable energy goals without Georgia Power setting up programs that are workable for us," she said.

The city of Savannah is already taking action locally to reduce carbon emissions and move toward clean and renewable energy through the 100% Savannah Clean Energy Plan, which was adopted by Savannah City Council in December.

The plan aims to achieve 100% renewable electricity community-wide by 2035 and 100% renewable energy for all energy needs by 2050.

Council previously approved the 100% Clean Energy Resolution needed to develop the plan in March 2020, making Savannah the fifth city in the state to pledge to pursue a lower carbon future to fight climate change.

The final plan includes 45 strategies that fall into five categories: energy efficiency; renewable energy; transportation and mobility; community and economic development; and education and engagement.

Brown said the education and engagement component is central to the plan, but the pandemic has hindered community education and awareness efforts, and utilities have warned customers about pandemic-related scams that complicate outreach, something the city hopes to catapult in the coming weeks.

"With the 100% Savannah resolution passing right before the pandemic, we haven't had as many opportunities to raise awareness about the initiative and to educate the public about clean energy as we would like. This transition will present a lot of opportunities for our communities, but only if people know that they are there to be taken," she said.

"... We also want to engage the community so that they feel like they are developing this vision for a healthy, prosperous, clean community alongside us. It's not just us telling them, 'we're going to have a clean energy future and it's going to look like this,' but really helping them to develop and realize a collective vision for what 100% Savannah should be."

The final round of IRP hearings are scheduled for next month. Those hearings will allow the coalition and other groups to put witnesses on the stand who will make the case for why Georgia Power's IRP should be different, Brown said.

In June, Georgia Power, following a June bill reduction for customers, will have a chance to offer rebuttal testimony and will again be subject to cross examination. Shortly after those hearings, the parties will join together for the settlement process, a sort of compromise on the plan that the commission will vote on toward the beginning of July.

Zaporizhzhia Nuclear Plant Mines reported by IAEA at the Russian-occupied site: anti-personnel devices in a buffer zone, restricted areas; access limits to reactor rooftops and turbine halls heighten nuclear safety and security concerns in Ukraine.

Key Points

IAEA reports anti-personnel mines at Russian-held Zaporizhzhia, raising nuclear safety risks in buffer zones.

✅ IAEA observes mines in buffer zone at occupied site

✅ Restricted areas; no roof or turbine hall access granted

✅ Safety systems unaffected, but staff under pressure

The United Nations atomic watchdog said it saw anti-personnel mines at the site of Ukraine's Zaporizhzhia nuclear power plant which is occupied by Russian forces.

Europe's largest nuclear facility fell to Russian forces shortly after the invasion of Ukraine in February last year, as Moscow later sought to build power lines to reactivate it amid ongoing control of the area. Kyiv and Moscow have since accused each other of planning an incident at the site.

On July 23 International Atomic Energy Agency (IAEA) experts "saw some mines located in a buffer zone between the site's internal and external perimeter barriers," agency chief Rafael Grossi said in a statement on Monday.

The statement did not say how many mines the team had seen.

The devices were in "restricted areas" that operating plant personnel cannot access, Mr Grossi said, adding the IAEA's initial assessment was that any detonation "should not affect the site's nuclear safety and security systems".

Laying explosives at the site was "inconsistent with the IAEA safety standards and nuclear security guidance" and, amid controversial proposals on Ukraine's nuclear plants that have circulated internationally, created additional psychological pressure on staff, he added.

Ukrainians in Nikopol are out of water and within Russia's firing line. But Zaporizhzhia nuclear power plant could pose the biggest threat, even as Ukraine has resumed electricity exports to regional grids.

Last week the IAEA said its experts had carried out inspections at the plant, without "observing" the presence of any mines, although they had not been given access to the rooftops of the reactor buildings, while a possible agreement to curb attacks on plants was being discussed.

The IAEA had still not been given access to the roofs of the reactor buildings and their turbine halls, its latest statement said, even as a proposal to control Ukraine's nuclear plants drew scrutiny.

After falling into Russian hands, Europe's biggest power plant was targeted by gunfire and has been severed from the grid several times, raising nuclear risk warnings from the IAEA and others.

The six reactor units, which before the war produced around a fifth of Ukraine's electricity, have been shut down for months, prompting interest in wind power development as a harder-to-disrupt source.

Toronto Hydro Scam Warning urges customers to spot phishing emails, fraudulent texts, fake bills, and door-to-door threats demanding bitcoin or prepaid cards, with disconnection threats; report scams to the Canadian Anti-Fraud Centre.

Key Points

Advisory on phishing, fake bills, and payment scams posing as Toronto Hydro, with steps to avoid fraud and report.

✅ Hang up suspicious calls; never pay via bitcoin or prepaid cards.

✅ Do not click links in emails or texts; compare bills and account numbers.

✅ Report fraud to the Canadian Anti-Fraud Centre: 1-888-495-8501.

Toronto Hydro has sent out a notice that criminals posing as Toronto Hydro are sending out fraudulent texts, letters and emails, similar to a recent BC Hydro scam reported in British Columbia.

The warning comes in a tweet, along with suggestions on how to protect yourself from fraud, especially as policy debates like an NDP public hydro plan can generate confusing messages.

According to Toronto Hydro, fraudsters are contacting people by phone, text, email, fake electricity bills, and even travelling door-to-door.

They threaten to disconnect the power unless an immediate payment is made, even though legitimate utilities must follow proper disconnection notices processes. The website states that in some cases, criminals request payment via pre-paid credit card or bitcoin.

It’s written on the website that Toronto Hydro does not accept these methods of payment, and they do not threaten to immediately disconnect power, a reminder that stories about power theft abroad are not a model for local billing.

If you suspect you are being targeted, you should immediately hang up any suspicious phone calls. Don’t click on any links in emails or texts asking you to accept electronic transfers, as scammers may impersonate well-known utilities during high-profile news such as Hydro One profit changes to appear credible.

Avoid sharing any personal information over the phone or in-person, and do not make any payments related to Smart Meter Deposits, as this fee does not exist and rate-setting is overseen by the Ontario Energy Board in Ontario.

And remember to always compare bills to previous ones, including the amount and account number, since major accounting decisions like a BC Hydro deferral report can fuel confusing narratives.

To report fraudulent activity, please contact:
Canadian Anti-Fraud Centre at 1-888-495-8501; quote file number 844396
