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
Xinggong Subdistrict, Dalian Xinggong Subdistrict, Dalian Xinggong Subdistrict () is a township-level division of the north of the Shahekou District of Dalian, Liaoning, China. Xinggong Subdistrict is first and always well known as Xinggong Street or Xinggong Jie () because of the important and famous street which Dalian people always call by "Xinggong Street" instead of "Xinggong Subdistrict" where Xi'an Road Commercial Zone is. Xinggong Subdistrict was also an important Japanese (Kwantung Leased Territory) machi called by where was. The area of Xinggong Subdistrict is 4 km. It has 16 villages/communities like Xingxin Community, and 256 neighborhoods/community groups. Until 2016, the population of
