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
Homosexualities: A Study of Diversity Among Men and Women review from Michael Lynch in "The Body Politic". The book was also reviewed by Norman C. Murphy in "The Advocate". With Dean Gengle, Murphy presented a discussion with Bell about his book. Lynch argued that "Homosexualities" was in part an attempt by Bell and Weinberg to overcome statistical weaknesses in the work of Kinsey and his colleagues, and that as a result they had put more effort into "data processing" than into "understanding the premises and conclusions of the study." He suggested that they were "sometimes silently at odds" with Kinsey and his colleagues, and that they had limited their
