RWE starts Warsaw EV pilot

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."

UK EV Per-Mile Taxes are reshaping road pricing and vehicle taxation for electric cars, raising fairness concerns, climate policy questions, and funding needs for infrastructure and charging networks across the country.

Key Points

They are per-mile road charges on EVs to fund infrastructure, raising fairness, emissions, and vehicle taxation concerns.

✅ Propose tax relief or credits for EV owners

✅ Consider emission-based road user charging

✅ Invest in charging networks and road infrastructure

As the UK continues its push towards a greener future with increased adoption of electric vehicles (EVs) and surging EV interest during supply disruptions, a growing number of electric car drivers are voicing their frustration over the current tax system. The debate centers around the per-mile vehicle taxes that are being proposed and implemented, which many argue are unfairly burdensome on EV owners. This issue has sparked a broader campaign advocating for a more equitable approach to vehicle taxation, one that reflects the evolving landscape of transportation and environmental policy.

Rising Costs for Electric Car Owners

Electric vehicles have been hailed as a crucial component in the UK’s strategy to reduce carbon emissions and combat climate change. Government incentives, such as grants for EV purchases and tax breaks, have been instrumental in encouraging the shift from petrol and diesel cars to cleaner alternatives, even as affordability concerns persist among many UK consumers. However, as the number of electric vehicles on the road grows, the financial dynamics of vehicle taxation are coming under scrutiny.

One of the key issues is the introduction and increase of per-mile vehicle taxes. While these taxes are designed to account for road usage and infrastructure costs, they have been met with resistance from EV drivers who argue that they are being disproportionately affected. Unlike traditional combustion engine vehicles, electric cars typically have lower running costs compared to petrol or diesel models and, in many cases, benefit from lower or zero emissions. Yet, the current tax system does not always reflect these advantages.

The Taxation Debate

The crux of the debate lies in how vehicle taxes are structured and implemented. Per-mile taxes are intended to ensure that all road users contribute fairly to the maintenance of transport infrastructure. However, the implementation of such taxes has raised concerns about fairness and affordability, particularly for those who have invested heavily in electric vehicles.

Critics argue that per-mile taxes do not adequately take into account the environmental benefits of driving an electric car, noting that the net impact depends on the electricity generation mix in each market. While EV owners are contributing to a cleaner environment by reducing emissions, they are also facing higher taxes that could undermine the financial benefits of their greener choice. This has led to calls for a reassessment of the tax system to ensure that it aligns with the UK’s climate goals and provides a fair deal for electric vehicle drivers.

Campaigns for Fairer Taxation

In response to these concerns, several advocacy groups and individual EV owners have launched campaigns calling for a more balanced approach to vehicle taxation. These campaigns emphasize the need for a system that supports the transition to electric vehicles and recognizes their role in reducing environmental impact, drawing on ambitious EV targets abroad as useful benchmarks.

Key proposals from these campaigns include:

1. Tax Relief for EV Owners: Advocates suggest providing targeted tax relief for electric vehicle owners to offset the costs of per-mile taxes. This could include subsidies or tax credits that acknowledge the environmental benefits of EVs and help to make up for higher road usage fees.

2. Emission-Based Taxation: An alternative approach is to design vehicle taxes based on emissions rather than mileage. This system would ensure that those driving high-emission vehicles contribute more to road maintenance, while EV owners, who are already reducing emissions, are not penalized.

3. Infrastructure Investments: Campaigners also call for increased investments in infrastructure that supports electric vehicles, such as charging networks and proper grid management practices that balance load. This would help to address concerns about the adequacy of current road maintenance and support the growing number of EVs on the road.

Government Response and Future Directions

The UK government faces the challenge of balancing revenue needs with environmental goals. While there is recognition of the need to update the tax system in light of increasing EV adoption, there is also a focus on ensuring that any changes are equitable and do not disincentivize the shift towards cleaner vehicles, while considering whether the UK grid can handle additional EV demand reliably.

Discussions are ongoing about how to best implement changes that address the concerns of electric vehicle owners while ensuring that the transportation infrastructure remains adequately funded. The outcome of these discussions will be critical in shaping the future of vehicle taxation in the UK and supporting the country’s broader environmental objectives.

Conclusion

As electric vehicle adoption continues to rise in the UK, the debate over vehicle taxation becomes increasingly important. The campaign for fairer per-mile taxes highlights the need for a tax system that supports the transition to cleaner transportation while also being fair to those who have made environmentally conscious choices. Balancing these factors will be key to achieving the UK’s climate goals and ensuring that all road users contribute equitably to the maintenance of transport infrastructure. The ongoing dialogue and policy adjustments will play a crucial role in shaping a sustainable and just future for transportation in the UK.

Manitoba Hydro Allegations Investigation reveals RCMP and OPP probes into 1960s abuses in northern Manitoba, affecting Fox Lake Cree Nation, citing racism, discrimination, sexual assault, and oversight by the IIU and Clean Environment Commission.

Key Points

A coordinated probe into historic abuses tied to Manitoba Hydro projects, led by OPP and IIU after RCMP referral.

✅ OPP to investigate historical cases involving Hydro staff and contractors.

✅ IIU to examine any allegations implicating Manitoba RCMP officers.

✅ Findings follow CEC report on racism and abuse near Fox Lake.

Manitoba RCMP have called in outside investigators to probe alleged assaults linked to hydro projects in the province’s north during the 1960s.

RCMP say any historical criminal investigations involving Manitoba Hydro employees or contractors will be handled by the Ontario Provincial Police.

The Independent Investigation Unit of Manitoba, the province’s police watchdog, will investigate any allegations involving RCMP officers.

A report released last month by an arm’s-length review agency outlined racism, discrimination and sexual abuse at the Crown-owned utility’s work sites dating back decades, while projects like Site C COVID-19 updates provide contemporary examples of reporting.

Much of the development at that time was centered around the community of Gillam and the nearby Fox Lake Cree Nation.

The report said the presence of a largely male construction workforce led to the sexual abuse of Indigenous women, some of whom said their complaints were ignored by the RCMP, and in a different context, Hydro One worker injury highlights safety risks in the sector.

Premier Brian Pallister says his government is taking the right approach to addressing alleged sexual assaults and racism by Manitoba Hydro workers against members of a remote northern First Nation, while pandemic cost-cutting at Manitoba Hydro has shaped recent operations.

Pallister made his first public comments about the allegations after a private meeting with Prime Minister Justin Trudeau on Tuesday evening, as COVID-19 reshaped Saskatchewan and other Prairie priorities were in focus.

The allegations, made by members of Fox Lake Cree Nation, were revealed in a report produced by the Clean Environment Commission. The report was released by the provincial government in August, although it was completed in May.

Allegations against Manitoba Hydro workers: What you need to know

"My reaction would be that's deplorable behaviour, and I have to admit, my puzzlement is why this wasn't investigated sooner or didn't come to light sooner," Pallister said, adding that he believes his government has taken the right approach by referring the information to the RCMP.

Some members of Fox Lake Cree Nation say the government didn't give them any advance notice of the release of the report, so the community was traumatized when it hit the news.

Pallister said his government didn't want to delay the release of the report.

'Pure trauma': Fox Lake members stricken after hasty release of troubling report

"I think the right thing to do is release the report. A lot of this information was in the public domain over the last number of weeks and months anyway. It wasn't the case of it being new in that respect," he said.

However, he accepted criticism of the timeline of the report's release.

"I would rather accept those criticisms, than accept the argument that we were in any way covering up information that is important to be released," he said.

Fox Lake Chief Walter Spence has said he expects Pallister to visit the community.

The premier said Tuesday he was not sure of the effectiveness of such a trip.

"I think most of the communities would prefer that there be electricity jobs for young Canadians created in their communities, that there be better water, many other tangible things rather than symbolism," he said.

"That's what I'm hearing and I've been in dozens of First Nations communities in the last two years."

Paris E-Scooter Ban: Voters back ending rental scooters after a public consultation, citing road safety, pedestrian clutter, and urban mobility concerns; impacts Lime, Dott, and Tier operations across the capital.

Key Points

A citywide prohibition on rental e-scooters, approved by voters, to improve safety, order, and walkability.

✅ Non-binding vote shows about 90% support citywide.

✅ About 15,000 rental scooters from Lime, Dott, Tier affected.

✅ Cites 2022 injuries, fatalities, and sidewalk clutter.

Parisians have voted to rid the streets of the French capital of rental electric scooters, with an overwhelming 90% of votes cast supporting a ban, official results show, amid a wider debate over the limits of the electric-car revolution and its real-world impact.

Paris was a pioneer when it introduced e-scooters, or trottinettes, in 2018 as the city’s authorities sought to promote non-polluting forms of urban transport, amid record EV adoption in France across the country.

But as the two-wheeled vehicles grew in popularity, especially among young people, and, with similar safety concerns prompting the TTC winter ban on lithium-ion e-bikes and scooters in Toronto, so did the number of accidents: in 2022, three people died and 459 were injured in e-scooter accidents in Paris.

In what was billed as a “public consultation” voters were asked: “For or against self-service scooters?”

Twenty-one polling stations were set up across the city and were open until 7pm local time. Although 1.6 million people are eligible to vote, turnout is expected to be low.

The ban won between 85.77% and 91.77% of the votes in the 20 Paris districts that published results, according to the City of Paris website on what was billed as a rare “public consultation” and prompted long queues at ballot boxes around the city. The vote was non-binding but city authorities have vowed to follow the result, echoing Britain's transport rethink that questions simple fixes.

Paris’s socialist mayor, Anne Hidalgo, has promoted cycling and bike-sharing but supported a ban on e-scooters, as France rolls out new EV incentive rules affecting Chinese manufacturers.

In an interview with Agence France-Presses last week, Hidalgo said “self-service scooters are the source of tension and worry” for Parisians and that a ban would “reduce nuisance” in public spaces, with broader benefits for air quality noted in EV use linked to fewer asthma ER visits in recent studies as well.

Paris has almost 15,000 e-scooters across its streets, operated by companies including Lime, Dott and Tier. Detractors argue that e-scooter users disrespect the rules of the road and regularly flout a ban on riding on pavements, even as France moves to discourage Chinese EV purchases to shape the broader mobility market. The vehicles are also often haphazardly parked or thrown into the River Seine.

In June 2021, a 31-year-old Italian woman was killed after being hit by an e-scooter with two passengers onboard while walking along the Seine.

“Scooters have become my biggest enemy. I’m scared of them,” Suzon Lambert, a 50-year-old teacher from Paris, told AFP. “Paris has become a sort of anarchy. There’s no space any more for pedestrians.”

Another Parisian told BFMTV: “It’s dangerous, and people use them badly. I’m fed up.”

Julian Sezgin, aged 15, said he often saw groups of two or three teenagers on e-scooters zooming past cars on busy roads. “I avoid going on e-scooters and prefer e-bikes as, in my opinion, they are safer and more efficient,” he told the Guardian.

Bianca Sclavi, an Italian who has lived in Paris for years, said the scooters go “too fast” and should be mechanically limited so they go slower. “They are dangerous because they zip in and out of traffic,” she said. “However, it is not as bad as when they first arrived … the most dangerous are the drunk tourists!”

Hydro One Q2 Earnings surge on a one-time gain from a court ruling on a deferred tax asset, lifting profit, revenue, and adjusted EPS at Ontario's largest utility regulated by the Ontario Energy Board.

Key Points

Hydro One Q2 earnings jumped on an $867M court gain, with revenue at $1.67B and adjusted EPS improving to $0.39.

✅ One-time gain: $867M from tax appeal ruling.

✅ Revenue: $1.67B vs $1.41B last year.

✅ Adjusted EPS: $0.39 vs $0.26.

Hydro One Ltd., following the Peterborough Distribution sale transaction closing, reported a second-quarter profit of $1.1 billion, boosted by a one-time gain related to a court decision.

The power utility says it saw a one-time gain of $867 million in the quarter due to an Ontario court ruling on a deferred tax asset appeal that set aside an Ontario Energy Board decision earlier.

Hydro One says the profit amounted to $1.84 per share for the quarter ended June 30, amid investor concerns about uncertainties, up from $155 million or 26 cents per share a year earlier.

Shares also moved lower after the Ontario government announced leadership changes, as seen when Hydro One shares fell on the news in prior trading.

On an adjusted basis, it says it earned 39 cents per share for the quarter, despite earlier profit plunge headlines, up from an adjusted profit of 26 cents per share in the same quarter last year.

Revenue totalled $1.67 billion, up from $1.41 billion in the second quarter of 2019, while other Canadian utilities like Manitoba Hydro face heavy debt burdens.

Hydro One is Ontario’s largest electricity transmission and distribution provider, and its CEO compensation has drawn scrutiny in the province.

Site C Dam Update outlines hydroelectric budget overruns, geotechnical risks, COVID-19 construction delays, BC Hydro timelines, cancellation costs, and First Nations treaty rights concerns affecting renewable energy, ratepayers, and Peace Valley impacts.

Key Points

Overview of Site C costs, delays, geotechnical risks, and concerns shaping BC Hydro hydroelectric plans.

✅ Cost to cancel estimated at least $10B

✅ Final budget now about $16B; completion pushed to 2025

✅ COVID-19 and geotechnical risks drove delays and redesigns

The cost to cancel a massive B.C. energy development project would be at least $10 billion, provincial officials revealed in an update on the future of Site C.

Thus the project will go ahead, Premier John Horgan and Energy Minister Bruce Ralston announced Friday, but with an increased budget and timeline.

Horgan and Ralston spoke at a news conference in Victoria about the findings of a status report into the hydroelectric dam project in northeastern B.C.

Peter Milburn, former deputy finance minister, finished the report earlier this year, but the findings were not initially made public.

$10B more than initial estimate
On Friday, it was announced that the project's final price tag has once again ballooned by billions of dollars.

Site C was initially estimated to cost $6 billion, and the first approved budget, back in 2014, was $8.775 billion. The budget increased to $10.8 billion in 2018.

But the latest update suggests it will cost about $16 billion in total.

And, in addition to a higher budget, the date of completion has been pushed back to 2025 – a year later than the initial target.

Among the reasons for the revisions, according to the province, is the impact of COVID-19. While officials did not get into details, there have been multiple cases of the disease publicly reported at Site C work camps.

Additionally, fewer workers were permitted on site to allow for physical distancing, and construction was scaled back.

Also cited as a cause for the increased cost were "unforeseeable" geotechnical issues at the site, which required installation of an enhanced drainage system.

Speaking to reporters Friday, the premier deflected blame.

“Managing the contract the BC Liberals signed has been difficult because it transfers the vast majority of the geotechnical risk back to BC Hydro,” said Horgan.

Former Premier Christy Clark vowed to get the project to a point of no return, and in 2017 the NDP decided to continue with the project because of the cost of cancelling it.

The Liberals now say the clean energy project should continue, but deny they shoulder any of the blame.

“Someone has to take ownership – and it's got to be government in power,” said MLA Tom Shypitka, BC Liberal critic for energy. 

There are also several reviews underway, including how to change contractor schedules to reflect delays and potential cost impacts from COVID-19, and how to keep the work environment safe during the pandemic.

A total of 17 recommendations were made in Milburn's report, all of which have been accepted by BC Hydro and the province.

Among these recommendations is a restructured project assurance board with a focus on skill-specific membership and autonomy from BC Hydro.

Cost of cancelling the project
The report looked into whether it would be better to scrap the project altogether, but the cost of cancelling it at this point would be at least $10 billion, Horgan and Ralston said.

That cost does not include replacing lost energy and capacity that Site C's electricity would have provided, according to the province.

A study conducted in 2019 suggested B.C. will need to double its electricity production by 2055, especially as drought conditions are forcing BC Hydro to adapt power generation. 

The NDP government says the cost to ratepayers of cancelling the project would be $216 a year for 10 years. Going forward will still have a cost, but instead, that payment will be split over more than 70 years, the estimated lifetime of Site C, meaning BC Hydro customers will pay about $36 more a year once the site goes live, the NDP says, even as cryptocurrency mining raises questions about electricity use.

“We will not put jobs at risk; we will not shock people's hydro bills,” said Horgan.

"Our government has taken this situation very seriously, and with the advice of independent experts guiding us, I am confident in the path forward for Site C," Ralston said.

"B.C. needs more renewable energy to bridge the electricity gap with Alberta and electrify our economy, transition away from fossil fuels and meet our climate targets."

The minister said the site is currently employing about 4,500 people.

Arguments against Site C
While there are benefits to the project, there has also been vocal opposition.

In a statement released following the announcement that the project would go ahead, the Union of B.C. Indian Chiefs suggested the decision violated the premier's commitment to a UN declaration.

"The Site C dam has never had the free, prior and informed consent of all impacted First Nations, and proceeding with the project is a clear infringement of the treaty rights of the West Moberly First Nation," the UBCIC's secretary treasurer said.

Kukpi7 Judy Wilson said the UN's Committee on the Elimination of Racial Discrimination has called for a suspension of the project until it has the consent of Indigenous peoples.

"B.C. did not even attempt to engage First Nations about the safety risks associated with the stability of the dam in the recent reviews," she said.

"It is unfathomable that such clear human rights violations are somehow OK by this government."

Chief Roland Wilson of the West Moberly First Nation said he was disappointed the province didn’t consult his and other communities prior to making this announcement. In an interview with CTV News, he said he was offered an opportunity to join a call this morning.

“We signed a treaty in 1814,” he said. “Our treaty rights are being trampled on.”

Wilson said his nation has ongoing concerns about safety issues and the plans to flood the Peace Valley. West Moberly is in a bitter court battle with the province.

At the BC Legislature, Green Party Leader Sonia Furstenau slammed the government’s decision.

“It is an astonishingly terrible business case in any circumstances, but considering that we lose the agricultural land, the biodiversity, the traditional treaty lands of Treaty 8, this is particularly catastrophic,” she told reporters.

She went on to accuse the NDP government of keeping bad news from the public. She alleged the NDP knew of serious problems before last fall’s unscheduled election, but chose not to release information.

Prior to the decision former BC Hydro president and a former federal fisheries minister are among those who added their voices to calls to halt work on the dam.

They were among 18 Canadians who wrote an open letter to the province calling for an independent team of experts to explore geotechnical problems at the site.

In the letter, signed in September, the group that also included Grand Chief Stewart Phillip of the UBCIC wrote that going ahead would be a "costly and potentially catastrophic mistake." 

According to Friday's update, independent experts have confirmed the site is safe, though improvements have been recommended to enhance oversight and risk management.

Earlier in the project, a B.C. First Nation claimed it was a $1-billion treaty violation, though an agreement was reached in 2020 after the province promised to improve land management and restore traditional place names in areas of cultural significance.

The Prophet River First Nation will also receive payments while the site is operating, and some Crown land will be transferred to the nation as part of the agreement. 

Additionally, residents of a tiny community not far from the site is suing the province over two slow-moving landslides they claim caused property values to plummet.

Nearly three dozen residents of Old Fort are behind the allegations of negligence and breach of their charter right to security of person. The claim is tied to two landslides, in 2018 and 2020, that the group alleges were caused by ground destabilization from construction related to Site C.

One of the landslides damaged the only road into the community, leaving residents under evacuation for a month.
