  • 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.
  • "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."
  • 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."
  • 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.
  • "Plant-e, a company based out of the Netherlands, has found a way to harness electricity from living plants."
  • Electricity used to power Wi-Fi hotspots, cell phone chargers, streetlights.
  • Naturally occurring micro-organisms to donate their electrons to a supplied electrode.
  • Graphene has great conductivity making it good for use in batteries but has small surface area.
  • "Conductivity from the graphene and the 3D nature of the structures […] should increase the storage capabilities of batteries."
  • Will aid in addressing climate change by providing storage for renewable energy.
  • The purpose of the Soccket is to give impoverished communities a source of electric light.
  • Harnesses kinetic energy generated during play and stores it inside the ball.
  • 30 minutes of play gives generates three hours of LED light.
  • On a very windy day "sustainable wind-power technologies harnessed and collected 144% of one days electricity needs."
  • surplus power exported to Norway, Germany, and Sweden
  • Germany & Norway can store energy in hydropower systems for later use
  • Berkshire, England "Bus Hound" set record for a regular bus by driving at 77mph
  • Its fuel is made from animal waste which is broken down in a process called anaerobic digestion to produce biogas, which is then liquefied
  • It normally carries passengers around Reading at 56mph
  • "Plant-e, a company based out of the Netherlands, has found a way to harness electricity from living plants"
  • "Their plant power technology is also being used to power the company’s headquarters in Wageningen."
