This Week's Sci-light!

January is a time of new beginnings, fresh starts, and New Year's resolutions.  Perhaps the idea of a making a resolution that you anticipate breaking in just a few days has soured you on the fundamental idea of a clean slate.  It is true that you can change at any time, but there is something to the power of collectively bringing in the new.

An article on e Science News! (a great source for breaking science news) celebrated a discovery that could pave the way for a new chapter in world energy needs.  The burning of fuels derived from organic materials, commonly called fossil fuels, meets many of our energy needs today.  (If you take for granted electricity, try a day without it and see how much work you get done and fun you have.)  But meeting the needs of a world that is increasingly becoming electricity dependent, is no small matter.

Alternative energy sources are one of the avenues being explored for just such a purpose.  Researchers are experimenting with energy produced by wind, sun and water.  A book I recently found, Gust or Bust, by Hannah Flynn and Ljiljana Grubisic takes readers through the benefits and challenges of windmills in the context of climate science and energy production.  One of the problems with using wind energy, for example, is that the energy produced varies.  To compensate for low wind, the energy generated during high wind has to be stored in batteries.  The cost of the batteries is high and reduces the cost-effectiveness of this form of energy...

...but there is a new solution!  Scientists at the Harvard School of Engineering and Applied Sciences in collaboration with colleagues from Chemistry, Materials Science and Chemical Biology have developed a "metal-free flow battery that relies on the electrochemistry of naturally abundant, inexpensive, small organic (carbon-based) molecules called quinones, which are similar to molecules that store energy in plants and animals."

The article adeptly outlines the current challenges of energy storage with traditional batteries and presents the clear economic and efficiency advantages of their battery comprised of electrochemical conversion hardware and a separate chemical storage tank.

The application of such a invention gives me hope.  But what really strikes me is all the interdisciplinary work that was done to invent the battery.  Such work cannot be done by solitary individuals but through shared ideas and actions.

At any rate, here's to the the New Year--may it be filled with new imaginations, new collaborations, new actions and new discoveries!
