Re: Space Pioneers
Actually, there are a lot of extremely good profit opportunities we know about, & could actually begin to implement, today. Satellite solar power & asteroid mining are two very obvious ones. The main problem is that capital requirements are high & the big payoffs are typically 20 years or more out — it's just impossible to get commercial money for that kind of time these days. The US rail system was built on hundred-year bonds, but that was under the gold standard.
There are some very credible prospects in the range of three years & sooner, which piggy-back on the long-term ones, but they don't stand on their own. Hence my position that the initial impetus has to be supplied by another means. In the past people have assumed that government would furnish the jumpstart, but it doesn't appear likely. I think I have identified a viable alterntive approach, & if not that'll just be too bad.
