I am a student. We are working on a design project, and long story short, we need to transmit power on the moon. We have decided on a gear system but still need to transmit from the gear output to the axles, and were considering v-belts. Does a belt exist that could operate in such extreme temperatures (~+100 to -200 degrees C)? I can't seem to find much on this, any leads to info or suggestions would be appreciated. Thanks!
