Wildfires Are Not Just a U.S. Problem Windracers, a British firm specializing in autonomous flight and swarm technology, is using drones to seek out and extinguish nascent or early stage wildfires. A recent report from the University of Sheffield alerts us, “Wildfires have become more frequent, larger, and more severe in the United Kingdom. Factors such as land use changes, higher temperatures, drought conditions, and climate change contribute to this trend. In 2022, there were over 44,000 wildfires—a rise of 72% from the previous year.” Sheffield and the University of Bristol have partnered with Windracers, a British automated aerial delivery company, to seek out and contain wildfires early in their development cycles. To add a trans-Atlantic link, Purdue University is joining the effort. International Concerns Windracers’ Links to English Universities As noted above, Windracers is working with the Universities of Sheffield and Bristol, combining talents in artificial intelligence and swarm technology.

Carbon Fiber, Batteries and Clean Air from CO2
Creators of a one-step process called STEP (Solar Thermal Electrochemical Photo) claim a world of benefits, including pulling carbon dioxide from the air and turning it into useful things, such as fuels, cement, and cheap carbon fiber. The process can also purify and desalinate water, according to many of the 300 peer-reviewed papers by Dr. Stuart Licht of George Washington University and his graduate students. The elevator speech regarding their research can be found on the home page for the group. “A new fundamental solar process has been introduced. STEP efficiently removes carbon from the atmosphere and generates the staples needed by society, ranging from fuels, to metals, bleach and construction materials, at high solar efficiency and without carbon dioxide generation. By using the full spectrum of sunlight, STEP captures more solar energy than the most efficient solar cell or photoelectrochemical processes.” According to the British Broadcasting Company (BBC), the sample of nanofibers Dr. Licht showed participants at the Autumn Meeting of the …
