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
Homosexuality: A Psychoanalytic Study of Male Homosexuals are consistent with those of Bieber's work. They maintain that Bell "et al."′s finding that "detached-hostile father" is relatively characteristic of 52% of the white homosexual men in their study and 37% of white heterosexual men is quite similar to what was reported by Bieber "et al". The philosopher Timothy F. Murphy described Bieber "et al."′s research methodology as flawed. William Spurlin suggested that "Homosexuality" informed stereotypes later promulgated by the media.
