The problem with the sun as it was once put to me is that nobody can put a meter on it and bill us. Which is why renewable energy is not about the science. It's about us and what we think is more important. Money today or survival tomorrow. There is an interesting side discussion here about the accessibility of young people to potentially shocking technology in the future but again it's less about the technology and more about why do we not trust our children with danger. Maybe it's because we let the Pentagon get first access to any scientific discoveries we make. How can we weaponize space (as is being done) and then lecture about good and evil? More on the "Death Ray" below over here.
