Oh well. I had noticed that K. Eric Drexler, on a web page, has a list of patents, and the solar sail is one of them (4,614,319). There are already solar sails in production. In 1991, for high school debate, we had a space exploration plan with solar sails.

I guess we are around at the right time for the next century of things. Considering life extension, we might be around for the century after that, etcetera.

The most efficient means to power a laser, or, anything, is matter-to-energy transformation. Again, this is barring extra-dimensional sources of power.

I've always been very fond of space, it is a romantic ideal, the so-called "final frontier."
