Well, with Graphene, we could have some dreams actualized soon. Have you heard of Space Solar Sails? Well, that's our Wakandian spaceship!

This part of your post reminds me of my article titled "it's actually possible to tap loads of energy from the sun at night".
Cost of setting up large materials in space is a major challenge to this technology. Graphene would help a great deal in making this become a reality.

This has to go down as my favourite read so far. If Chemistry was thought this way in school, I wouldn't have been so awful at that subject. Nice work @mrbreeziewrites
