Scientists in Australia have demonstrated a new way to apply a passivating contact layer to silicon cells. They produced an n-type cell with aluminum-titanium passivating contact and 21.9% efficiency, and claimed the technique could open up new possibilities for the use of transition metal oxides in cell passivation.
The vehicles we’ll see on the roads in a decade’s time will be radically different from what we have at present. Design language will change a lot, as hinted by the concepts and prototypes put together by big names and budding automotive designers.
The focus definitely will be on personal mobility in the most sustainable manner possible. Compact vehicles that will trade off the greatest of luxuries for a more sensible method of commuting will be the norm. This boomerang-shaped two-seater vehicle with multiple use-case scenarios is different from what we’ve seen so far. Even in the automotive landscape dominated by some really bizarre vehicle concepts.

Bill Gates is funding more research into dimming the sun! Check out how solar geoengineering works.
Bill Gates is a man who recently suggested the world should eat 100% synthetic beef, has argued that bitcoin is bad for the planet, co-founded Microsoft, and remains one of the richest people in the world.
He is also very interested in dimming the light from the sun to reduce or delay the effects of climate change, according to a forthcoming study from the Bill Gates-backed Harvard University Solar Geoengineering Research Program — which aims to evaluate the efficacy of blocking sunlight from reaching our planet’s surface.
For one month Rob Greenfield lived just like the average person and WORE every single piece of trash he created. Why? To create a visual of how much trash just one of us creates and serve as a mirror to society to self-reflect, question habits and explore alternatives to live in balance with Earth.
Rob Greenfield is an activist and humanitarian dedicated to leading the way to a more sustainable and just world. He embarks on extreme projects to bring attention to important global issues and inspire positive change. His work has been covered by media worldwide including National Geographic and he’s been named “The Robin Hood of modern times” by France 2 TV. This talk was given at a TEDx event using the TED conference format but independently organized by a local community.
Electric buses are great for municipalities. They are cheaper to operate and maintain than diesel buses, and they emit no pollutants. For passengers, they’re awesome because they’re comfortable, smooth, and relatively quiet. But, even a decade ago they were almost unheard of. The price of batteries has come down significantly in recent years, making electric buses a more viable option for many city transit agencies.
So, it’s no surprise that sales of electric buses have exploded as prices fell and made them the superior choice in most circumstances. In 2012, only 15 electric buses were put into service throughout Europe’s urban areas. In 2021, every fourth newly registered bus in Western Europe was electric. Now, they’re showing up all over the place in much greater numbers.

The bizarre remarks were an answer to a question during a Shareholder meeting. Elon Musk was ask about the fate of Tesla if he had to step down as CEO after being forced to buy Twitter.
Bill Gates-founded Breakthrough Energy Ventures co-led a $44 million funding round for a startup that aims to accelerate solar far construction.
Breakthrough Energy Ventures, a climate change solution-focused VC firm backed by the likes of Bill Gates, has joined a $44 million backing of solar startup Terabase Energy, a press statement reveals.

The challenge: The building and construction sector is responsible for a big chunk of global carbon emissions. A lot of those emissions come from the production of cement, which is the second most consumed material on the planet behind water.
Cement produces emissions in two main ways. One is through the chemical reactions that occur while sintering limestone and other materials to make “clinker,” a key component of cement. The other comes from using fossil fuels to heat up kilns to very high temperatures.

The electrification of heating systems could play a significant role in building decarbonization. Heat pumps are emerging as a solution.
Iranian scientists have demonstrated a multi-layer silicon nanoparticle (SNP) solar cell based on nanoparticles that are densely stacked inside a dielectric medium. They considered different SNP structures and configurations to tailor these particles as a p–n junction cell.
