TOP 5 NEWS ARTICLES

Hydrogen Air Taxi Takes Flight, 523 Miles with Zero Emissions LINK 

• Joby Aviation successfully completed a 523-mile test flight of a hydrogen-powered VTOL aircraft, emitting only water vapor.

• The hydrogen system extends the range of their electric VTOLs, making regional travel between cities more viable with zero in-flight emissions.

• Despite its promise, hydrogen power remains expensive and is mostly produced from natural gas, a major CO2 source, though efforts are underway to expand green hydrogen production.

Innovative Startup Turns Carbon into Butter LINK 

• Savor has developed a sustainable butter alternative using a petrochemical process that transforms CO2 into fatty acids, which are then used to create a butter-like product.

• This innovation not only offers a sustainable food option but could also significantly impact agricultural practices by reducing the reliance on greenhouse-gas-intensive crops.

• The potential for synthetic foods like this to address global food shortages and reduce environmental impacts is vast, though challenges in cost and public acceptance remain.

New Alloy Allows Chips to Harvest Their Own Energy LINK

• The alloy comprises silicon, germanium, and tin, reducing thermal conductivity while maintaining electrical properties, ideal for thermoelectric uses.

• It can integrate into the CMOS chip production process, allowing waste heat from electronics to be converted back into usable energy.

• The innovation could lead to more energy-efficient electronic devices and expands potential applications in thermoelectrics, photonics, and spintronics.

Swiss Researchers Recycle Gold from Electronics with Cheese Whey LINK

• Scientists have developed a method to extract gold from e-waste using "denatured" whey proteins from cheese, offering an environmentally friendly recycling option.

• The technique uses a whey protein sponge to collect gold ions, which can then be recovered by heating, proving to be cost-effective compared to traditional methods.

• This approach not only addresses the e-waste problem but also utilizes food industry byproducts, reducing food waste and potential environmental impacts.

Startup Helps Southeast Asian Farmers Cut Methane Emissions LINK

• Rize supports rice farmers in Southeast Asia with alternate wetting and drying techniques to significantly reduce methane emissions.

• The new methods not only cut emissions but also improve water efficiency and crop yields.

• Rize provides essential agronomic support and resources to ensure sustainable farming practices and financial viability.
