What Does This Mean For Space Development?
Will expensive solar cells be put in space because they are more efficient up there?
Will this drive lunar manufacture of solar cells and asteroid mining?
Or will the rise in demand be matched with new searches and finds of these materials so it quickly becomes a no issue.
