Space-Based Solar Power: a solution to our burning need for energy

People burn things. This crude way to get energy has done wonders for us as a species, but I think it’s about time we moved on.

The Biological Singularity

If you’re a sci-fi reader, you are probably familiar with the idea of the “technological singularity“.

The "explorer" analogy and US spaceflight

The other day, the blog Sociological Images had a thought-provoking post about a Canadian ad campaign which invokes the idea of exploration and discovery to promote Canadian tourism. It got me thinking about one of the most common defenses of U.S. space exploration: that it is the natural next step for a nation founded on exploration to start exploring space.
