First ‘sand battery’ developed to heat homes or balance renewable energy for grid

“The construction of the storage went well, especially considering that the solution is completely new,” said Polar Night co-founder and chief technology officer Markku Ylönen in a statement.

“We managed to get everything in order despite some challenges and a short delay.”

He said the first installation has shown that the system “has even more potential than we initially calculated”.

New Artificial Photosynthesis Method Grows Food With No Sunshine

Photosynthesis uses a series of chemical reactions to convert carbon dioxide, water, and sunlight into glucose and oxygen. The light-dependent stage comes first, and relies on sunlight to transfer energy to plants, which convert it to chemical energy. The light-independent stage (also called the Calvin Cycle) follows, when this chemical energy and carbon dioxide are used to form carbohydrate molecules (like glucose).

A research team from UC Riverside and the University of Delaware found a way to leapfrog over the light-dependent stage entirely, providing plants with the chemical energy they need to complete the Calvin Cycle in total darkness. They used an electrolysis to convert carbon dioxide and water into acetate, a salt or ester form of acetic acid and a common building block for biosynthesis (it’s also the main component of vinegar). The team fed the acetate to plants in the dark, finding they were able to use it as they would have used the chemical energy they’d get from sunlight.

They tried their method on several varieties of plants and measured the differences in growth efficiency as compared to regular photosynthesis. Green algae grew four times more efficiently, while yeast saw an 18-fold improvement.

A new breakthrough could turn windows into active solar panels

The dream of transforming windows into active power generators has just edged one step closer to realization.

A team of researchers from ARC Centre of Excellence in Exciton Science led by Professor Jacek Jasieniak from Monash University’s Department of Materials Science and Engineering has created perovskite cells with a conversion efficiency of 15.5 percent that allows more than 20 percent of visible light through, a press release states.

This improves the stability of solar windows while allowing more natural light in, which means the amount of visible light passing through the cells is remarkably now reaching glazing levels, increasing their potential for usage in a wide range of real-world applications.

How technology helps scientists explore Amazonian biodiversity without human interference

Spotting wildlife in these dark and dense forests teeming with insects and spiny palms is always challenging. This is because of the very nature of biodiversity in Amazonia, where there is a small number of abundant species and a greater number of rare species which are difficult to survey adequately.

Understanding what species are present and how they relate to their environment is of fundamental importance for ecology and conservation, providing us with essential information on the impacts of human-made disturbances such as climate change, logging, or wood-burning. In turn, this can also enable us to pick up on sustainable human activities such as selective logging – the practice of removing one or two trees and leaving the rest intact.

As part of BNP’s Bioclimate project, we are deploying a range of technological fixes like camera traps and passive acoustic monitors to overcome these hurdles and refine our understanding of Amazonian wildlife. These devices beat traditional surveys through their ability to continuously gather data without the need for human interference, allowing animals to go about their business undisturbed.

A Biodegradable Spray Applied to Fresh Produce Could Eliminate a Lot of Foodborne Illnesses and Plastic Packaging

That’s not a Faberge egg on the right. It is an avocado sprayed with an antimicrobial fibre to keep the produce from rotting and could become the future way we preserve fruit and vegetables.


Naturally occurring pullulan fibres with antimicrobial agents when sprayed on test avocados proves better than plastic packaging.

Soof Azani and Lir Braverman propose collapsible solar-powered bike for last-mile deliveries

Soof Azani and Lir Braverman’s proposal for a solar-powered cargo bike that aims to facilitate local deliveries is the latest of 10 visionary transportation projects selected for Dezeen’s Future Mobility Competition powered by Arrival.

Called D50, Azani and Braverman’s concept aims to combine solar power with micro-mobility in a bid to improve the distribution of goods while reducing carbon emissions.

The vehicle, which is intended for developing countries, is designed for heavy loads to expedite last-mile deliveries for traders and businesses.

IKEA will now sell solar panels

IKEA, the world’s largest furniture retailer, has announced plans to sell home solar panels in the US — a move that could democratize and demystify access to solar.

Solar hesitancy: The benefits of solar go beyond protecting the environment — solar panels are cheaper than ever, and between the lower energy bills and government subsidies, a home solar system could pay for itself before the panels need to be replaced.

Despite that, only 3.2% of single-family detached homes have solar panels, according to the National Renewable Energy Laboratory.

Off-grid hydrogen generation technology for on-demand power

Spotted: Although relatively expensive to produce at present, and with storage often cited as a concern, green hydrogen fuel production is increasing. A naturally occurring and superabundant element, hydrogen is popular for several reasons, including the ability to produce it using renewable energy sources. And now, Element 1’s modular, grid-independent hydrogen generation technology is making the fuel even more accessible.

Designed to efficiently convert methanol to hydrogen to electricity, the technology supports both hydrogen fuel cell vehicles and electric vehicles. The company’s catalytic reactor heats a methanol and water feedstock mix before sending it through a membrane purifier for almost 100 per cent fuel cell grade hydrogen.

Because the modular system produces the fuel as needed, the risk of combustion is nearly eliminated, and specialty storage facilities are redundant. This is because the only material that needs to be stored and transported is the methanol and water feedstock. The hydrogen is then produced on-site. Element 1 provides both small and large-scale solutions, as well as a mobile version specifically for refuelling electric vehicles on the go.
