Hver 24. time roterer planeten v\u00e5r \u00e9n gang rundt sin egen akse, noe som gir oss \u00e9n dag og \u00e9n natt. Men hva om du var p\u00e5 M\u00e5nen? Den g\u00e5r i bane p\u00e5 en annen m\u00e5te. Det kan v\u00e6re mye sollys i 14 dager, etterfulgt av 14 dager hvor det er veldig m\u00f8rkt.<\/p>\n<\/div>\n<p>Dette utgj\u00f8r et problem for fremtidige menneskelige m\u00e5neutforskere, da de vil trenge sollys p\u00e5 solcellepanelene som igjen produserer den s\u00e5rt tiltrengte elektrisiteten. I hvert fall har det alltid v\u00e6rt planen\u2026 inntil n\u00e5! ESA-forskere unders\u00f8ker en ny m\u00e5te \u00e5 bruke laget av m\u00e5nest\u00f8v som dekker M\u00e5nen p\u00e5, som en slags batteri. Om dagen p\u00e5 M\u00e5nen absorberer og lagrer m\u00e5nest\u00f8vet energi fra sollyset.
