This Week's Question: Scientists are exploring the possibility of utilizing space solar power for Earth-bound purposes. The United States, China, India and Japan all have projects at various stages of development that would see robots assemble solar arrays that could provide the Earth with clean, renewable energy, delivered wirelessly via microwaves and laser beams. According to experts, space is the ideal location for a solar power station as it would have access to uninterrupted power from sunlight. The final cost of the entire system, however, could easily reach $20 billion. What do you think? Will we deliver electricity from space?
