Transporting materials to the moon is expensive ... This is why so many things designed from space travel are lightweight. Whaaaat?!

  Cost to get things into orbit is expensive - I don't have the numbers but the amount of extra fuel for every pound is, though roughly 90% of the weight of any launch vehicle is fuel. So if you can have something lighter do the same job, then costs etc really start to factor in hard.
