  • First ever optical ‘rectenna’ uses billions of carbon nanotubes to capture solar energy
  • Combines functions of "an antenna and a rectifier diode to convert light directly into DC current"
  • Georgia Tech Associate Professor: “We could ultimately make solar cells that are twice as efficient at a cost that is ten times lower"
  • Kirigami is a Japanese paper cutting technique, not as "well known as it's flashier cousin, origami"
  • Flexible, "amorphous panel strips are made of gallium arsenide that are cut in a kirigami-like fashion"
  • Can "make almost any solar cell up to 40% more efficient"
  • 8 schools already have solar power; 9 remaining schools will by the end of the year
  • Aims to cut utility costs; projected to save the district $175,000 a year.
  • Also "implemented a behavioral energy conservation program, which trained employees to make sure energy is not wasted when the district’s buildings are not occupied.
  • Cancer is "the leading cause of firefighter line-of-duty deaths in the United States;" 60% of career firefighters will die this way
  • greater risk of contracting multiple myeloma, non-Hodgkin lymphoma, prostate, and testicular cancers"
  • Researchers believe chemicals in synthetic materials are increasing cancer rates
  • "Poorer nations along the equator are not benefiting from the world's increased coffee drinking over the last 20 years."
  • "The shift to 'technified' coffee production [occured] in the 1970s and 1980s."
  • It has "created harsher economic and ecological consequences for heavy coffee-producing nations."
  • "Five solar farms will produce a combined 2,500 kilowatts of electricity."
  • "The highway solar farms are part of an initiative launched two years ago by the state Department of Transportation."
  • Five more "solar farms will be built next year near Stockbridge and in Salisbury."
  • The study, published in Proceedings of the National Academy of Sciences, looked at 186 species of pelagic seabirds.
  • The researchers looked at previous studies done on seabirds between 1962 and 2012; 29% of birds studied had ingested plastic in 1962.
  • "Concentrations of plastic now as high as 580,000 pieces" per sq/k of ocean.
  • "Trace amounts of toxic substances used to make plastics don’t contaminate the food or beverages they contain."
  • "Those plastic products may cause health concerns decades after they’ve been used and thrown in the trash bin."
  • "Lead, mercury, chromium, cadmium, and antimony [...] can cause numerous health problems such as neurological and renal damage."
  • A 12-megawatt (MW) solar power plant "makes it the first 100-percent solar-powered airport in the world."
  • "The Airport Authority of India has plans to build 50MW of solar at various airports by 2016."
  • "India is already committed to building 100GW of solar by 2022."
  • CSIRO aims to "obtain a bee's-eye perspective on the cause of the alarming rise in the insects' mortality rate."
  • "Sensors are tiny radio frequency identification (RFID) tags measuring 2.5 x 2.5 millimetres and weighing 5.4 milligrams."
  • "Results in it only being able to carry two-thirds of its normal payload of water, pollen and nectar."
  • Harnesses ocean's stored energy "using the temperature difference between warm surface and cold deep water to produce electricity."
  • OTEC (ocean thermal energy conversion) beginning to supply energy to Kona, Hawaii.
  • Energy stored in ocean's surface estimated to be greater than the planet's energy needs.
