Donald,
Does your push for Mars indicate giving up on Earth's prospects or is it only a backup? New developments, including the plasma engine, gives us several months round-trip access rather than several years, though I gather your concept is long-term and self-sufficient with an eye toward terraforming.
My essay speaks of "looking beyond" in terms of beyond Earth and beyond the conventional and "looking within" to harness the untapped potential of the human brain, which many see as the microcosm of the universe.
I would like to see your comments.
Jim
