We came up with a portfolio of technologies that would help us turn the ideas into something usable and eco-friendly. It included direct manufacturing, fiber optics for data transmission and the idea of transparent Glass Fiber Reinforced Polymer (GFPR) as a strong and unorthodox material for the aircraft's outer shell. We were trying to determine how different technologies might evolve in context to others -- important, because only if you understand certain technologies and their huge potential are you able to pick the appropriate ones.
