Most people will say yes, and affirm that bigger is better. On the other hand, sometimes smaller can be better, as we recently discussed using superconductors to reduce the size and increase the power of wind generators. Piezo- and pyroelectrical materials, such as PbZr0.2Ti0.8O3 [PZT], have properties that are well-known and demonstrated […]
