Capturing Carbon and Making Airplanes from It

Climate scientists have tracked the growing percentage of carbon dioxide (CO2) in the air, and noted a correlation between that rise and global warming.  Scientists from Michael Mann to Benjamin Santer have measured the changes in CO2 levels against climate change, with 97 out of 100 climate scientists accepting that human activities and rises in CO2 (and other greenhouse gases such as methane) are affecting our overall climate. Not to start an argument about this matter, this entry looks at a novel method of removing CO2 from the atmosphere and using it to make possible carbon materials that would be used in aerospace and other components.  The question of carbon removal usually includes some method of storing it.  Futurism.com has a great overview (too large to display here) that shows those methods. One enterprising group of scientists avoids the costly and difficult means of carbon storage and instead focuses on retrieving carbon and turning it into carbon wool, a usable …

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 …
