Atwater believes that a combination of light management at the nanoscale and clever device architecture can yield "a quantum leap" in cell efficiency.

Atwater believes that a combination of light management at the nanoscale and clever device architecture can yield "a quantum leap" in cell efficiency. Today's "series" triple-junction cells stack three photovoltaic semiconductors on top of each other. Each semiconductor is optimized for a specific wavelength range. But the series nature of the device means that an enormous effort is spent in the growth of the layers, as well as separating or buffering the layers. The layer with the lowest current limits the current for the chip and minimizes the power generated.
In my run for U.S. Senate against Utah's Orrin Hatch, I posted many progressive ideas and principles that I internalized over the years. I'm leaving that site up indefinitely, since it describes what I believe most members of our species truly want: www.voteutah.us. I thank those who sent such wonderful comments, even though it forced me to go buy a few larger hats, which were among my top campaign expenses (just kidding).
My forever-to-write novel (now my favorite book for some unfathomable reason), A Summer with Freeman, finally got out the door, via Kindle and CreateSpace. Readers of this site, and anyone else with two or more brain cells who want some "serious humorous relief" may want to check it out: http://www.opednews.com/articles/A-Summer-with-Freeman-nov-by-Daniel-Geery-130528-385.html
My family and I lived off the grid in an earth-sheltered, solar powered underground house for 15 years, starting in the early '80s, proving, at least to myself, the feasibility of solar power. Such a feat would be much infinitely easier with off-the-shelf materials available now, though the bureaucracy holding us back is probably worse. http://www.opednews.com/articles/Living-on-Sunshine-Underg-by-Daniel-Geery-110318-547.html
I wrote a book on earth-sheltered solar greenhouses that has many good ideas, but should be condensed from 400 down to 50 pages, with new info from living off the grid. It's on my "to do" list, but you can find used copies kicking around online. Just don't get the one I see for $250, being hawked by some capitalist... well, some capitalist.
I'm 68 with what is now a 26 year old heart--literally, as it was transplanted in 2005 (a virus, they think). This is why I strongly encourage you and everyone else to be an organ donor--and get a heart transplant if you're over 50, unless your name is Dick Cheney.
I may be the only tenured teacher you'll meet who got fired with a perfect teaching record. I spent seven years in court fighting that, only to find out that little guys always lose (http://www.opednews.com/articles/Letter-to-NEA-Leadership--by-Daniel-Geery-101027-833.html; recommended reading if you happen to be a parent, teacher, or concerned citizen).
I managed to get another teaching job, working in a multi-cultural elementary school for ten years (we had well over 20 native tongues when I left, proving to me that we don't need war to get along--no one even got killed there!). http://www.opednews.com/articles/opedne_daniel_g_060716_alternatives_to_exti.htm
I spent a few thousand hours working on upward-gliding airships, after reading The Deltoid Pumpkin Seed by John McPhee. But I did my modelling in the water, so it took only two years and 5,000 models to get a shape that worked. You can Google "aquaglider" to learn more about these. As far as I know, this invention represents the first alteration of Archimedes'principle, spelled out 2,500 years ago.
"Airside," the water toys evolved into more of a cigar shape, as this was easier to engineer. Also, solar panels now come as thin as half a manila folder, making it possible for airships to be solar powered. You can see one of the four I made in action by Googling "hyperblimp"(along with many related, advanced versions).
Along with others, I was honored to receive a Charles Lindbergh Foundation Award, to use my airships to study right whales off Argentina. Now we just have to make it happen and are long overdue, for reasons that would probably not fit on the internet.
In 2010 I married a beautiful woman who is an excellent writer and editor, in addition to being a gourmet cook, gardener, kind, gentle, warm, funny, spiritual, and extremely loving. We met via "Plenty-of-Fish" and a number of seemingly cosmic connections. Christine wrote Heart Full of Hope, which many readers have raved about, as you may note on Amazon.
I get blitzed reading the news damn near every day, and wonder why I do it, especially when it's the same old shit recycled, just more of it. In spite of Barbara Ehrenreich and reality, I'm a sucker for positive thinking and have read many books on it. I find many many of them insane and the source of much negativity on my part. My favorites these days are by Alan Cohen, who seems to speak my language, and likewise thinks a bit like Albert Einstein did (as do I on this note). Albert: "Try and penetrate with our limited means the secrets of nature and you will find that, behind all the discernible laws and connections, there remains something subtle, intangible and inexplicable. Veneration for this force beyond anything that we can comprehend is my religion. To that extent, in fact, I am religious."
Though I rapidly note that I've kept alive my deceased and "devout atheist" friend's book, http://www.opednews.com/articles/The-Foundation-of-Religion-by-Daniel-Geery-110510-382.html
Lastly, kudos to Rob Kall and those who make OEN the site that it is: one of the last bastions of free speech.
