Windows are great for letting in light, but in summer months that comes with an unwanted side order of heat, causing many people to run the air conditioning non-stop. Now, researchers have developed windows that can change color automatically when heated by sunlight, to keep buildings cool – and to top it off, they’re solar panels as well.

Color-changing glass has been around for a long time, most commonly as transition lenses for eyeglasses that tint automatically under bright light. More recent developments have made it electronic and switchable on demand, and scaled it up to window size. At the same time, transparent (or semi-transparent) solar cells are getting more efficient, to the point where they can be fitted into windows.

In the new study, researchers at the US Department of Energy’s National Renewable Energy Laboratory (NREL) has combined the two technologies into one window. The “thermochromic photovoltaic” tech, as they call it, can switch colors when heated up by sunlight to block glare and reduce the need for cooling, and when it does it also starts harvesting energy from that light.

As the electric vehicle sector grows, the demand for batteries is poised to see a significant increase. This is a big opportunity for companies like LG Chem, which supplies batteries for several EV makers like Tesla. Amidst this surging demand, LG Chem revealed on Wednesday that it is planning on tripling its production capacity for cylindrical batteries, the type used by the Silicon Valley-based electric car maker.

LG Chem currently forecasts a further rise in its battery sales and profits this fourth quarter. This is rather optimistic of the South Korean company considering that the company has already posted record quarterly earnings thanks to its growing EV battery business. “Sales are continuously expected to grow thanks to greater shipments of automotive batteries and cylindrical batteries for EVs,” LG Chem noted.

Elon Musk’s carmaker reported net income of $331 million on revenue of $8.77 billion in the third quarter.

FERNDALE, Mich. – Samples from Ferndale’s municipal water system have lead levels in the drinking water exceeding state standards, according to officials.

Oakland County Health Division (OCHD) was notified by the Michigan Department of Environment, Great Lakes, and Energy (EGLE) about the results from testing. Testing occurred as part of routine compliance sampling required by EGLE under Michigan’s Safe Drinking Water Act.

The OCHD is coordinating the distribution of free water filter kits to Ferndale residents who qualify on Oct. 28 from 3 to 6 p.m. at the Gary Kulick Community Center (1201 Livernois St, Ferndale, MI 48220).

Volcon is the latest startup hoping to bite off a piece of the growing electric motorcycle pie. The company’s new Volcon Grunt is poised to fill a gap in the market with an interesting mix of specs and pricing.

The Volcon Grunt is a fat tire electric motorcycle of sorts that doesn’t just talk the talk.

Plastic eating enzyme.

PLASTIC-EATING ENZYME: Researchers have re-engineered a plastic-eating enzyme to degrade bottles within days — and it might be ready to start eating our trash as soon as next year 👀.

A simple way to improve efficiency…

Solar panels offer huge potential to move more people away from electricity generated from burning coal, and a new innovation devised by scientists stands to more than double the amount of light captured by conventional solar cells.

In a new study, a team of scientists from the UK, Portugal, and Brazil discovered that etching a shallow pattern of grating lines in a checkerboard design on solar cells can enhance the current generated by crystalline silicon (c-Si) by as much as 125 percent.

Australia seems to be leading the way in terms of wind power as well. 😃

It was a big week for South Australia last week. First, as we wrote at the time, the state reached 100 per cent solar power (of state demand) for the first time on Sunday, October 11.

Then, just a few days later, the state reached 100 per cent wind power (of state demand), on Thursday, October 15.

Leiden chemists Marc Koper and Ian McCrum have discovered that the degree to which a metal binds to the oxygen atom of water is decisive for how well the chemical conversion of water to molecular hydrogen takes place. This insight helps to develop better catalysts for the production of sustainable hydrogen, an important raw material for the chemical industry and the fuel needed for environmentally friendly hydrogen cars. Publication in Nature Energy.

For years there has been a heated debate in the literature: how to speed up the electrochemical production of hydrogen on platinum electrodes in an alkaline environment? Chemist Ian McCrum watched from the sidelines and concluded that part of the debate was caused by the fact that the debaters were looking at slightly different electrodes, making the results incomparable. Time to change that, McCrum thought, who was a LEaDing Fellow postdoc in the group of Professor Marc Koper at the time.
