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. …
Thin, Light, Strong, and Energy Dense
2010’s Nobel Prize in Physics went to Andre Geim and Konstantin Novoselov, who extracted graphene from a piece of graphite when they stuck a piece of adhesive tape to it and peeled away a single atom-thick layer of the thinnest, strongest material in the world. The Nobel Prize web site explains other remarkable properties of this new material. “As a conductor of electricity it performs as well as copper. As a conductor of heat it outperforms all other known materials. It is almost completely transparent, yet so dense that not even helium, the smallest gas atom, can pass through it. Carbon, the basis of all known life on earth, has surprised us once again.” With studies in quantum physics and …
A Pair of Viruses Good for Your Computer – and Maybe Your Electric Vehicle
To say that your battery is “smoking” would normally be the sign of a failed circuit, but researchers at the A. James Clark School of Engineering and College of Agriculture and Natural Resources at the University of Maryland may be putting a virus that’s bad even for tobacco to good use in creating a battery that may be up to 10 times more powerful than today’s best lithium cells. Professor Reza Ghodssi, director of the Institute for Systems Research and Herbert Rabin Professor of Electrical and Computer Engineering at the Clark School, is “harnessing and exploiting the ‘self-renewing’ and ‘self-assembling’ properties” of the Tobacco Mosaic Virus (TMV), which in its unrestrained natural state destroys tobacco, tomatoes, peppers and other leafy green things. …
