A device that can generate electricity while desalinating seawater has been developed by researchers in Saudi Arabia and China, who claim that their new system is highly efficient at performing both tasks. The device uses waste heat from the solar cell for desalination, thereby cooling the solar cell. It also produces no concentrated brine as waste, cutting its potential environmental impact.
In many parts of the world, climate change and population growth are putting huge demands on freshwater supplies. In some coastal regions, desalination – removing the salt from brackish water or seawater to turn it into fresh water – is increasingly being used to meet demand. Indeed, there are now around 16000 desalination plants around the world producing about 95 million cubic metres of freshwater every day.

Elon Musk and Jeff Bezos have been feuding publicly for years, but the Tesla chief recently came out in praise of the Amazon boss.
3D-printed devices made from a biodegradable paper-like material could power the Internet of Things in a more sustainable way.

The researchers were inspired by bone and cartilage when designing the new membrane.
You’ve likely heard of solar energy, but what is osmotic energy?
Researchers have created an unusual new alloy made up of not two, but five different metals, and put it to work as a catalyst. The new material is two-dimensional, and was able to convert carbon dioxide into carbon monoxide effectively, potentially helping to turn the greenhouse gas into fuels.
The new alloy belongs to a class of materials called transition metal dichalcogenides (TMDCs), which are, as the name suggests, made up of combinations of transition metals and chalcogens. Extremely thin films of TMDCs have recently shown promise in a range of electronic and optical devices, but researchers on the new study wondered if they could also be used as catalysts for chemical reactions.
The thinking goes that because reactions occur on the surface of a catalyst, materials with high surface areas will be more effective catalysts. And as sheets only a few atoms thick, TMDCs are almost nothing but surface area.
Fortunately, automakers, suppliers and government leaders are examining things like electric vehicles and where batteries and other parts come from as they push for North American production. The Department of Energy has released a National Blueprint for Lithium Batteries, and a plan to support the domestic battery production to meet growing needs as people go back to work and school in the fall.
It is tempting to see the chip storage problem as just a technology story. But it also has real-world implications for our national security as so much of defense relies on computers and communications in the era of modern warfare.
As Americans celebrate our independence, we have to re-commit to being independent when it comes to reliance on others for goods and services that fuel our lives. We can’t make everything at home, but we can make more and ensure that disruptions abroad don’t reverberate, negatively, at home. As Congress continues to debate infrastructure and other major legislation, and the COVID-19 pandemic retreats, we will need to work together to ensure that we are prepared for whatever 2022 might bring.
The US power grid needs all of support it can get. Sad that some would stand in the way of progress.
There is no love lost between the notorious Koch brothers and the nation’s railroad industry, and the relationship is about to get a lot unlovelier. A massive new, first-of-its-kind renewable energy transmission line is taking shape in the Midwest, which will cut into the Koch family’s fossil energy business. It has a good chance of succeeding where others have stalled, because it will bury the cables under existing rights-of-way using railroad rights-of-way and avoid stirring up the kind of opposition faced by conventional above-ground lines.
The Koch brothers and their family-owned company, Koch Industries, have earned a reputation for attempting to throttle the nation’s renewable energy sector. That makes sense, considering that the diversified, multinational firm owns thousands of miles of oil, gas, and chemical pipelines criss-crossing the US (and sometimes breaking down) in addition to other major operations that depend on rail and highway infrastructure.
