The big coal interests have a favored saying: “There is no silver bullet.” This old adage suggests there is no single solution to the growing energy needs and concerns of this country. While this is obviously true, the only solution (or “silver bullet”) that these charlatans ever talk about is “clean” coal. Ironically enough, “clean” coal is a fantasy notion as mythical as the werewolves and other monsters silver bullets were reputed to destroy.

For those unfamiliar with monster lore and mythology, silver bullets were capable of destroying everything from werewolves to vampires – creatures that had no other weakness or vulnerability. This metaphor is quite fitting to our dilemma of increasing energy demand while preserving the ecosystem, for it is a dilemma that seems insurmountable and unsolvable. Our civilization is built upon electricity and the idea of continuing our lifestyles without it is unfathomable to many Americans. But, as with the legendary monsters of old, a silver bullet does exist to address and conquer this problem – at least metaphorically.

It is not wind power, or solar power, or even energy efficiency, nor is it some yet-to-be-discovered technology that we hang unreasonable hopes upon. It is a mindset. A way of viewing the world free from the burdensome fear and closed-mindedness of the energy industry’s status quo. The simple knowledge, which (more…)

An op-ed in the New York Times yesterday by O. Glenn Smith, a former NASA employee, suggests what is certainly a “thinking outside the box” kind of solution to our nation’s energy woes: solar panels…in outer space.

Smith recommends building large solar panels that would orbit the earth and send energy back to us via wireless radio waves. Apparently, the technology already exists, and the pro column reads something like this:

  • not hampered by weather
  • works 24 hours a day (the sun never sets in space)
  • environmentally friendly
  • cost-competitive with other renewables
  • makes use of the United States’ hefty investment in space travel

While I’m always glad to hear about innovations that will help our globe move toward a sustainable energy schema, I’m a little skeptical about the way Smith holds up this technology as the way of the immediate future. He opens his piece with this:

As we face $4.50 a gallon gas, we also know that alternative energy sources — coal, oil shale, ethanol, wind and ground-based solar — are either of limited potential, very expensive, require huge energy storage systems or harm the environment.

This quick dismissal of the alternative energy sources we know and love (except…how is coal alternative?) is questionable. For starters, I have a hard time believing that any energy system that must be installed and maintained outside our atmosphere will be less expensive than one based here on the earth’s surface.

Smith also ignores the benefits that energy sources like wind and ground-based solar provide that space-based solar does not. One of the great benefits of investing in wind and solar power is the creation of thousands of jobs, especially in rural areas. The fact that the handymen for these solar panels in space would have to also be astronauts prevents space-based solar from becoming a solution to the dearth of quality manufacturing and other blue-collar jobs in this country.

Some day, I hope we will see space-to-earth solar energy. But for now, let’s focus on all the untapped renewable energy potential here on terra firma before we pull a Buy N’ Large* and run to outer space in search of the answers.

But if the idea of space-based solar intrigues you, you can read more about it on this blog dedicated to the topic.
