Scientists have built a breakthrough device that can clean dirty water and turn it into clean hydrogen fuel. The “simple” device could be used in areas without resources or places where people live off the grid. And it is just one example of the many solutions that will be required to respond to pollution and give people access to both clean fuel and water, the researchers behind it say. The system is inspired by photosynthesis, the process where plants turn light into food. But previous versions of those “artificial leaves” have required clean water sources – whereas the new device can be used with polluted water and even produce clean drinking water at the same time. As such, scientists believe that it could help solve two problems at once: making green fuel and cleaning water so that it is ready to drink. “Bringing together solar fuels production and water purification in a single device is tricky,” said Chanon Pornrungroj from the University of Cambridge, the paper’s co-lead author. “Solar-driven water splitting, where water molecules are broken down into hydrogen and oxygen, need to start with totally pure water because any contaminants can poison the catalyst or cause unwanted chemical side-reactions.” The system uses a carbon mesh to absorb light and heat, creating water favour that is then turned into hydrogen for fuel by a photocatalyst. That carbon mesh also repels water, so that the system can float and its important parts can be kept from being damaged by water. The device is also able to harness more of the Sun’s energy than previous examples, which have used only a small portion of the spectrum of light. The new system has a white layer on top to absorb UV rays, with the rest being used lower down to vaporise the water. “This way, we’re making better use of the light – we get the vapour for hydrogen production, and the rest is water vapour,” said Dr Pornrungroj. “This way, we’re truly mimicking a real leaf, since we’ve now been able to incorporate the process of transpiration.” The researchers behind the breakthrough noted that the system was simple to make, and was especially able to deal with very polluted water. As such, it could be a key way of working towards a sustainable future, they said – even though it is just a proof of concept for now. “The climate crisis and issues around pollution and health are closely related, and developing an approach that could help address both would be a game-changer for so many people,” said Cambridge’s Erwin Reisner, who led the work. The device is described in a new paper, ‘Hybrid photothermal-photocatalyst sheets for solar-driven overall water splitting coupled to water purification’, published in Nature Water today.

Canadian Prime Minister Justin Trudeau hit out at Facebook as detrimental to democracy after the news service began blocking access to news stories on its platforms in Canada in the midst of a wildfire crisis. “It is so inconceivable that a company like Facebook is choosing to put corporate profits ahead of ensuring that local news organizations can get up-to-date information to Canadians and reach them,” Mr Trudeau said prior to a cabinet meeting on Prince Edward Island on Monday in comments reported by the New York Post. Mr Trudeau’s anger at Facebook comes as the company has started enforcing a new policy blocking Canada-based users from accessing news stories in response to a recent Canadian law that requires the company to pay publishers for content shared on the platform. Facebook, in response, has sharply reduced its role as a news service in the country — an issue in an emergency like the one Canada is facing now as its summer wildfires have forced the evacuation of some 35,000 families in the western province of British Columbia. “Democracy depends on people being able to trust high-quality journalism and of all sorts of different perspectives and points of view,” Mr Trudeau said on Monday. “But right now, in an emergency situation, up-to-date local information is more important than ever.” The prime minister’s contention is that Facebook’s policy is threatening people’s safety — a charge that a Facebook spokesperson denied in a statement provided to the Associated Press in which they said that Canadian Facebook users can still use the platform “to connect with their communities and access reputable information, including content from officials.” The dispute between Canadian lawmakers and companies like Facebook and Google set to be affected by the payment law has been brewing for months. In comments made last year, Mark Zuckerberg, the CEO of Facebook’s parent company, Meta, said the Canadian law “is based on the incorrect premise that Meta benefits unfairly from news content shared on our platforms, when the reverse is true.” In fact, experts say, the popularity of Facebook as a news-sharing platform has helped to drive a number of news agencies out of business while reportedly profiting in some cases from the dispersal of misinformation. Meanwhile, Canadian wildfires continue to burn and push families out of their homes. Per the Post, there have been more than 5,700 fires in Canada this summer that have burned more than 50,000 square miles — with the resulting smoke felt at various points in states across the US.
