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
Dalian most liveable city in China according to "China Daily". Standard Mandarin is usually spoken in Dalian because it is a city with people from various locations. But Dalian natives use Dalian dialect, which belongs to the Jiaoliao Mandarin subgroup spoken in parts of Shandong and Liaoning provinces. Most of the residents of Dalian were farmers and fishermen who had come from Shandong Province in a large population move, the "Chuang Guandong", during which era Dalian was occupied by the Japanese as the Kwantung Leased Territory. The Dalian dialect incorporates a few loanwords from Japanese and Russian (very rare in Chinese),
