Generating small amounts of electricity by squeezing luffa sponges Over the past several years, engineers have investigated the possibility of generating small amounts of piezoelectricity by taking advantage of footsteps, for example, or the movement of clothes as a person walks. Electricity generated and collected in such ways is seen as a possible way to charge personal devices.
Desalination system could produce freshwater that is cheaper than tap water The researchers estimate that if the system is scaled up to the size of a small suitcase, it could produce about 4–6 liters of drinking water per hour and last several years before requiring replacement parts. At this scale and performance, the system could produce drinking water at a rate and price that is cheaper than tap water.
Phosphazene-based electrolytes for high-voltage lithium batteries that work in extreme environments Ether-based electrolytes are also highly compatible with Li metal anodes, thus they can suppress the growth of dendrites while batteries are charging. Despite these advantages, many ether solvents are highly flammable, thus their use can greatly reduce the safety of battery cells.
Nestlé & Cargill use cocoa shell in new lowcarbon fertiliser We have to optimise natural resources to build resilience — this project is a very meaningful step towards a net zero future, says Nestlé’s Matt Ryan
AI to Protect Sea Turtle Populations AI-powered tracking systems have revolutionized our understanding of sea turtle migration patterns. These systems use satellite tags to track sea turtles migrating across the ocean. The tags collect data on the sea turtles’ movements, such as their speed, location, and depth. This data is then transmitted to satellites, which send it back to scientists.
GAC and Toyota develop ammonia engine for 90% CO2 reduction Four-cylinder engine is the first ammonia-fuelled engine for passenger cars; could be a hydrogen alternative
M&S switches from plastic bags for life to paper options Marks & Spencer (M&S) has replaced its plastic bags for life with paper alternatives that it claims are just as “strong and robust”
Apple touts its first carbon-neutral products The new Apple Watch lineup launched by the eponymous tech giant at its annual event is being marketed as carbon-neutral, due to a 75% reduction in lifecycle emissions.
Algae-Based Ice Cream, A Sustainable Frozen Treat That’s right, Sophie’s BioNutrients, a food tech company developing 100% plant-based and sustainable alternative protein for the industry, is now developing a vegan ice cream made from chlorella protein.
