The system developed in Milano is robust and it also has the potential to process information encoded in different coupled systems, including far and enormous galaxies. Thanks to these new results, it is now possible to simulate in the lab complex coupled systems, with order altered by stable defects, difficult to be reproduced otherwise since involving ginormous scale, like galaxies, or part of extreme hydrodynamic systems.

Water whirlpools, smoke rings, violent tornados and spiral galaxies are all examples of twists in fluids, although very different each other. Analogous twists, but in the realm of light, have been created by the research group coordinated by Antonio Ambrosio at the IIT-Istituto Italiano di Tecnologia (Italian Institute of Technology), in Milano (Italy). The results, published in the journal Nature Photonics, show the realization of 100 light vortices, coupled to form an ordered structure, a light crystal.

Mutual interaction of light and nanostructured materials is the focus of the research of Antonio Ambrosio, Principal Investigator of the research line Vectorial Nano-imaging at IIT in Milano and grantee of the ERC Consolidator project “METAmorphoses.”

Twisted light generators have been developed in the last few years, but they typically create a single vortex propagating alone in . IIT researchers have shown instead that it is possible to create 100 light vortices, coupled into an ordered light crystal.

Scientists at the US Department of Energy have created a low-cost molten salt battery that can store energy for months — potentially giving us a way to store and use energy from renewables year round.

The challenge: To stop climate change, we need to transition toward cleaner sources of energy.

Renewable energy (especially wind and solar) has become increasingly cheap to generate over the last couple decades, but storage is still an issue — we can burn as much coal or gas as we want, whenever we need it, but we can’t force the wind to blow.

Cognitive dissonance in the government’s decision to approve Bay-du-Nord while professing to fight fossil fuel emissions responsible for climate change.

The decision to approve Bay-du-Nord is based on the low emissions intensity of the oil that will be produced with no accounting for end-use.

There’s still a long way to go, but it’s an important milestone.

Ten years ago, solar and wind didn’t even make up 1% of our global energy mix. Now, in just a decade, they’ve reached 10%. It may not seem like much, but becoming such a significant part of the global energy mix in such a short time is remarkable — though there’s still a long way to go.

The past couple of years have been horrendous in more ways than one, but that doesn’t mean all is bad in the world. In fact, renewable energy continued its impressive growth, according to research from Ember, a climate and energy think tank.

As the world recoiled after the first year of the COVID-19 pandemic, economies were eager to reopen, and demand for energy surged. Some of what growth was covered by coal, which experienced its fastest growth since 1985, but renewables also rose to the challenge.

This doesn’t mean you need to don an ushanka and start marching. You can start taking collective action by focusing on community groups and connecting with climate leaders. This will likely help you solve other issues, too, like waste disposal, recycling, and community clean-up projects in your locale.

Conclusion

Combating climate change requires all of us to reconsider our individual and collective climate responsibility. As an individual, you can do your part and let others know what you are doing. It has never been easier to connect with the world and share than it is today. You can join others in writing letters to the editor of your local newspaper, or your local and national government representatives. You can join groups like Citizens’ Climate Lobby and learn how to engage policy decision-makers. And in your daily routines, you can lead by example.

Flooding is common in informal settlements in Bwaise, a neighbourhood in the Ugandan capital Kampala. Bwaise’s residents are largely excluded from planning and local decision-making processes, and have poor housing and limited access to sanitation and other essential services.

The installations of photovoltaic (PV) solar modules are growing extremely fast. As a result of the increase, the volume of discarded solar modules that end up on the recycling market annually will grow at the same rate in the near future. Currently, the aluminum, glass, and copper of the discarded modules are reprocessed; however, the silicon solar cells are not.

Now, researchers from the Fraunhofer Center for Silicon Photovoltaics CSP and the Fraunhofer Institute for Solar Energy Systems ISE, together with the largest German recycling company for PV modules, Reiling GmbH & Co. KG, have built new PERC solar cells with 100% crystalline silicon recycled from end-of-life photovoltaic panels.

The team has developed a process for recovering the silicon material with funding from the German Federal Ministry for Economic Affairs and Climate BMWK. The technique is claimed to recycle silicon from different types of crystalline silicon PV modules, regardless of manufacturer and origin.

Every industry will be affected by quantum computing. They will alter the way business is done and the security systems in place which protect data, how we battle illnesses and create new materials, as well as how we tackle health and climate challenges.

As the race to build the first commercially functional quantum computer heats up, here we discuss a handful of the ways quantum computing will alter our world.

The Charles M. Schulz Sonoma County Airport had two solar power systems installed onsite and made them live in February. Over the course of their electricity-generating life spans, they will offset thousands of tons of CO2 emissions and potentially save millions of dollars.

Sonoma County has been hit particularly hard by wildfires in the last several years. These natural disasters occur with some regularity on their own, but many believe the latest ones are connected to the effects of climate change. The county has been experiencing higher temperatures and droughts as well. As a result of these challenges, Sonoma County’s government set a goal for the county to be carbon neutral by 2030. The airport solar power installations fit within the carbon-free plan. (The California state government has a goal for California to be operating on clean, carbon-free electricity by 2045.)

Jon Stout, the Sonoma Airport Manager, and Rachel McLaughlin, ForeFront Power’s Vice President of Sales & Marketing, provided some insights to CleanTechnica about the new solar power systems. (The last three answers are from ForeFront.)
