Energy harvesting that are able to operate in higher temperature gradients, and that can conduct electricity well without also conducting heat (something that was until recently thought impossible ), will result in increased efficiency. Future work in thermoelectrics could be to convert wasted heat, such as in automobile engine combustion, into electricity. This type of harvesting is based on the changing capacitance of vibration-dependent capacitors. Vibrations separate the plates of a charged variable capacitor, and mechanical energy is converted into electrical energy. Electrostatic energy harvesters need a polarization source to work and to convert mechanical energy from vibrations into electricity. The polarization
Legend of the Guardians: The Owls of Ga'Hoole "Legend of the Guardians" is the in-flight movie on the aircraft piloted by Carol (Matt Damon), who claims his passengers "... think that $300 and a photo ID gives them the right to fly through the air like the guardian owls of legend!" In a 2014 episode of "The Simpsons", "Specs and the City", Bart considers giving Nelson an "Owls of Ga'Hoole"-themed Valentine, finding it fitting that Nelson should get a Valentine referencing what Bart considers a bad movie.
