Crystal discovered

 Scientists in China have identified massive thorium reserves that could dramatically change the future of global energy. Thorium is a naturally occurring radioactive element that can be used in advanced nuclear reactors to generate huge amounts of power with far greater safety and far less waste than traditional uranium-based systems.


• China has identified over 1 million tonnes of thorium in newly surveyed regions.

• Thorium-based reactors produce far less long-lived radioactive waste than uranium reactors.

• Thorium cannot easily be weaponized, making it significantly safer from a security standpoint.

• A single tonne of thorium can generate many times more energy than coal or uranium.

• China is actively developing molten salt thorium reactor (MSR) technology.

• These reactors operate at lower pressure, reducing meltdown risks.

• Thorium fuel cycles can run for decades with minimal refueling.


Why It Matters:

This discovery could reshape global energy systems by providing a long-term, low-carbon, and safer alternative to fossil fuels and conventional nuclear power. If fully developed, thorium energy could supply reliable electricity for centuries while drastically cutting emissions and nuclear waste.

Canada helps

 In a cozy corner of Canada, one café quietly changed the way people see leftovers. Near its exit door sits a small rack marked “Still Good.” On it, bagged muffins, sandwiches, and pastries that didn’tp sell that day are carefully labeled and placed for anyone to take—no questions, no payment.


It’s a simple setup. Items are wrapped, marked with the time they were made, and checked for freshness. Staff place them on the shelf at closing or during slower hours. Some customers take a bag on their way out, others leave one behind if they’ve bought too much. Local college students, delivery drivers, and even passersby have come to appreciate it—not out of desperation, but as a smart, respectful way to reduce waste.


The café’s owners say the idea started when regulars asked what happened to unsold items. Rather than toss them or compost food that was still perfectly edible, they created the rack as a quiet invitation. It works on trust and kindness. No one’s monitored, and nothing feels like charity—it just feels communal.


Since the “Still Good” rack appeared, a few neighboring cafés have adopted similar models. Some add coffee coupons or handwritten notes with jokes or encouragement. It’s small, but it reminds people that food doesn’t stop being valuable when it’s not bought—it still holds warmth, comfort, and care.

Repurpose Solar panel

 China has found a smart second life for retired solar panels by converting them into roadside shade roofs along highways. Instead of sending old panels to landfills, they are reused to create cool resting shelters for drivers, reducing waste while improving road safety and comfort.


These recycled solar-panel canopies provide shade from intense heat, especially on long highway stretches where temperatures can soar. The structures lower surface temperatures underneath, helping drivers rest, cool down, and reduce fatigue—an important factor in preventing road accidents during long journeys.


What makes this innovation powerful is its circular economy approach. Even after solar panels lose peak efficiency for power generation, they can still function effectively as durable roofing material. This reduces disposal costs, cuts environmental pollution, and extracts extended value from renewable energy infrastructure.


As countries struggle with the growing problem of solar waste, China’s approach shows how infrastructure, sustainability, and public convenience can work together. Turning “trash” into useful roadside shelters proves that renewable energy doesn’t stop being valuable when panels retire.

Solar windows

 Scientists have developed a brand new, clear coating that can be applied to any standard window to turn it into an effective solar panel – while still keeping the window largely transparent.

It's the work of a team from Nanjing University in China, and the researchers have already developed a small working prototype. Scale that up across all the available windows in the world, and we could be talking about terawatts of green energy.


Technically known as a "colorless and unidirectional diffractive-type solar concentrator" (CUSC), the coating directs some sunlight photons to the sides of the window panel where mounted photovoltaic cells convert them to electricity, while other light passes through.


The CUSC design is a step forward in integrating solar technology into the built environment without sacrificing aesthetics," says optical engineer Wei Hu. "It represents a practical and scalable strategy for carbon reduction and energy self-sufficiency."


This new coating beats existing options in terms of transparency, scalability, and efficiency, according to the researchers. The coating still lets 64.2 percent of visible light through, and maintains 91.3 percent color accuracy.

The material is made from cholesteric liquid crystals (CLCs), which have properties that enable the necessary interactions with light as it passes through. By stacking different layers of CLCs, the coating is able to cover the full spectrum of light.


Crucially, only one polarization of light – so a single one of the multiple ways that light is moving as a wave – is trapped and siphoned off for converting into energy. That enables the window to carry on functioning as a window.


"By engineering the structure of cholesteric liquid crystal films, we create a system that selectively diffracts circularly polarized light, guiding it into the glass waveguide at steep angles," says optical engineer Dewei Zhang.


In tests using green laser light – the color that human eyes are most sensitive to – 38.1 percent of the available energy was captured and converted, which is a high potential maximum for the technology. In tests using more realistic conditions and the full light spectrum, the overall efficiency was 18.1 percent.


The researchers have already been able to develop a 1-inch prototype using the coating, which collects enough energy to power a small fan. Scale that up to a full-size window, and a substantial amount of electricity could potentially be generated.


As the coating can be applied to normal windows, without too much in the way of modification, the team is hopeful that this can be made commercially viable – though there's still a lot of work to do before that happens.


The researchers say more can be done to improve the stability and the manufacturing of the coating, and the power conversion efficiency needs to be improved too – the total amount of incoming solar energy that actually makes it into usable electricity. Right now, that figure stands at a relatively low 3.7 percent.
