"heat (otherwise wasted) signals steered and amplified in energy-efficient data processing... non-conductive magnetic strips in conjunction with normal metal spacers conduct and amplify heat signals in controlled manner powering logical computing operations and heat diodes... slower speed better suited for next-generation computers which will be used to perform energy-saving calculations, than for everyday electronics such as smartphones"
