¿Qué le dicen el calor, el sonido y la electricidad? Quizás muchas cosas, si se toman aisladamente. O si se unen por parejas. Pero ahora un grupo de investigadores logró algo que suena extraño y que parece bien útil: pequeños aparatos que convierten el calor en sonido y luego en... electricidad. Una tecnología que promete transformar el calor desperdiciado en electricidad, lo que podría beneficiar los paneles de energía solar, así como enfriar computadores y radares.
El logro fue de físicos de la Universidad de Utah, liderados por Orest Symko, profesor de Física
Usar los sonidos para convertir el calor en electricidad tiene dos pasos claves. Symko y sus colegas desarrollaron varias máquinas de calor para lograr el primer paso: convertir calor en sonido.
Luego ellos convirtieron el sonido en electricidad utilizando tecnología existente, aparatos piezoeléctricos que cambian una presión que reciben a una corriente eléctriza. Piezo significa presión
La mayoría de los dispositivos acústicos de calor a electricidad coontruidos en el laboratorio de Symko están almacenados en resonadores de forma de cilindros que caben en la palma de la mano.

Heat, sound and electricity
What tell you the heat, the sound and the electricity? Perhaps many things, if they are taken separately. Or if they are united by pairs. But now a group of investigators obtained something that sounds strange and that seems really useful: small dvices that turn heat into sound and into… electricity. A technology that promises to transform the wasted heat into electricity, which could benefit panels of solar energy, as well as to cool computers and radars.The invent was made by physicists of the University of Utah, led by Orest Symko, professor of Physics.To use the sounds to turn heat into electricity has two key steps. Symko and its colleagues developed several heat engines to obtain the first step: to turn heat into sound. Then they turned the sound into electricity using existing technology, piezoelectric devices that change a pressure that receives to an electric current. Piezo means pressure.The majority of the heat-to-electricity acoustic devices built in the laboratory of Symko is housed in cylinder shaped resonators that fit in the palm of the hand.
