Fyzika, nie elektronika<\/strong><\/h2>\n

Vedci sa obr\u00e1tili na fyziku, nie na elektroniku, aby otvorili tieto prieduchy. Pou\u017eili kombin\u00e1ciu nylonu, ktor\u00fd reaguje na vlhkos\u0165 s vrstvou striebra zachyt\u00e1vaj\u00faceho teplo. Ke\u010f spodn\u00e1 vrstva nylonu navlhne, chce sa roztiahnu\u0165 ako plachta \u0165ahan\u00e1 po stran\u00e1ch.
