&nbsp;

Uma
equipe de engenheiros da Universidade de Colorado Boulder desenvolveu um
metamaterial escalável - um material de engenharia com propriedades
extraordinárias não encontradas na natureza - para atuar como um tipo de
sistema de ar condicionado para estruturas.&nbsp;Ele tem a capacidade de
arrefecer objetos mesmo sob luz solar direta com zero de energia e consumo de
água.

Quando
aplicado a uma superfície, o filme de metamaterial esfria o objeto embaixo eficientemente
refletindo a energia solar de entrada de volta para o espaço enquanto
simultaneamente permite que a superfície libere seu próprio calor na forma de
radiação térmica infravermelha.

O
novo material, que é descrito no &nbsp;journal&nbsp;Science,&nbsp;,
poderia fornecer um meio eco-friendly de refrigeração suplementar para usinas
termelétricas, que atualmente requerem grandes quantidades de água e energia
elétrica para manter as temperaturas de funcionamento das suas máquinas.
