“When it comes to photovoltaics, dust is the enemy. This is not a trivial concept, even if it may seem so at first glance; actually, the problem of soiling – the accumulation of dust, dirt or sand on PV panels – can decrease, sometimes significantly, the performance of solar power systems,” stated an Enel Green Power press release published on Friday.
Desert areas
“It’s an issue that’s particularly important in desert areas, areas with low rainfall, and those characterized by the presence of very dusty soil, where soiling can have a heavy impact on energy yield, but in any case, it’s something that concerns solar power everywhere, because regardless of location, cleaning the panels still involves costs, including environmental ones.”
The future of cities as seen by architects and urban planners. Future cities: Urban planners get creative | DW DocumentaryYOUTUBE.COMFuture cities: Urban planners get creative | DW Documentary.
Will the cities of the future be climate neutral? Might they also be able to actively filter carbon dioxide out of the air? Futurologist Vincente Guallarte thinks so. In fact, he says, our cities will soon be able to absorb CO2, just like trees do.
To accomplish this, Guallarte wants to bring sustainable industries and agriculture to our urban centers, with greenhouses atop every building. But in order for Guallarte’s proposal to work, he says, cities will have learn to submit to the laws and principles of nature.
Urban planners also have big plans for our energy supply. In the future, countries like Germany could become energy producers. In Esslingen am Neckar, residents are working on producing green hydrogen in homes, to be used as fuel for trucks. It’s a project that‘s breaking new ground, says investor Manfred Norbert.
Our future cities will be all about redefining a new normal. Architects and urban planners are expecting to see entirely new approaches to communal living, as well as new urban concepts for autonomous supply chains. The repurposing of old buildings, and the generation of food as well as energy, are other important topics.

Rechargeable lithium-ion batteries power smartphones, electric vehicles and storage for solar and wind energy, among other technologies.
They descend from another technology, the lithium-metal battery, that hasn’t been developed or adopted as broadly. There’s a reason for that: While lithium-metal batteries have the potential to hold about double the energy that lithium-ion batteries can, they also present a far greater risk of catching fire or even exploding.
Now, a study by members of the California NanoSystems Institute at UCLA reveals a fundamental discovery that could lead to safer lithium-metal batteries that outperform today’s lithium-ion batteries. The research was published today in the journal Nature.
Canadian architecture studio Atelier l’Abri has built a series of A-Frame buildings for the Farouche Tremblant agrotourism site in Québec’s Mon-Tremblant National Park, which were designed to “recede in the landscape”.
Intending to celebrate and showcase the surrounding untamed woodlands, Atelier l’Abri created a cafe, farm and four rental micro–cabins that act as a basecamp for visitors wanting to explore the nearby Devil’s River and its valley.
Sitting among the wild terrain, the four small rental cabins have steep-pitched roofs clad in cedar shingles that extend to the ground to form sloping walls.
Transforming cars that go from tearing up the tarmac to soaring through the skies at the touch of a button. It sounds like science fiction, but that might be the future we’re looking at, as America’s regulatory body for commercial flight and transportation, the Federal Aviation Administration, certified to test a bona fide flying car.
The vehicle — which has a flying range of around 177km on a full charge — is the brainchild of Alef Automotive, a Californian startup backed by high-profile venture capitalist Tim Draper (whose other seed investments include Tesla and SpaceX).
Transparent electronic devices could have numerous valuable real-world applications. Among other things, they could enable the creation of new optical devices, smart gear or wearables, invisible solar panels and integrated communication systems.
Researchers at Xidian University, Southeast University and Wuhan University of Technology recently developed new, highly promising, transparent metadevices based on quasi-one-dimensional surface plasmon polariton (quasi-1D SPP) structures. These devices, introduced in a paper published in Nature Electronics, could be used to develop optically and radiofrequency transparent wireless communication systems and other promising technologies.
“Transparent and invisible electronic device is a fascinating goal that scientists and engineers are enthusiastically pursuing,” Prof. Bian Wu, one of the researchers who carried out the study, told Tech Xplore. “Currently, transparent electronics typically rely on the intrinsic properties of optically conductive materials, which are not radiofrequency transparent and have low operating efficiency. SSPs can be used to concentrate, channel and enhance energy. However, the use of SPPs in the development of optical and radiofrequency transparency remains blank.”

This highly anticipated refresh promises exciting changes to both the interior and exterior of the popular Model Y.
MIT researchers have discovered that when you mix cement and carbon black with water, the resulting concrete self-assembles into an energy-storing supercapacitor that can put out enough juice to power a home or fast-charge electric cars.
We’ve written before about the idea of using concrete for energy storage – back in 2021, a team from the Chalmers University of Technology showed how useful amounts of electrical energy could be stored in concrete poured around carbon fiber mesh electrodes, with mixed-in carbon fibers to add conductivity.
MIT’s discovery appears to take things to the next level, since it does away with the need to lay mesh electrodes into the concrete, and instead allows the carbon black to form its own connected electrode structures as part of the curing process.
