Solar Power for the Military:

Deja Vu All Over Again

I recently saw an article discussing the use of solar panels by the U.S. military.  It cited a Department of Energy (DOE) study concluding that the military needs to rely more on solar power in order to eliminate weaknesses in the grid.  The article speculated that, with military funding to help address some of the drawbacks of solar power (including energy storage), there might be a knock-on effect for the general public as well.

The story brought back memories.  Early in my career, I worked for an Air Force think tank called Analytic Services (or ANSER).  Since I was the resident nuclear engineer, by extension, I was also assigned other energy-related projects.  Which is how I came to work on a project to explore the possible use of renewable energy to provide power for military bases housing MX missile systems.  I worked on it for some months, and even published a paper on it.  Alas, this was so long ago that I couldn't find it on the Web when I looked, but I did find a passing reference to the concept at the end of a 1979 article.

I hadn't thought about that project in years, but seeing the news item made me reflect on how many technologies don't get off the ground the first time.  This is true in the nuclear area, too, as we are now talking about technologies like molten salt for nuclear reactors as though it was a brand-new idea, when in fact, that was one of the technologies that was explored in the earliest days of nuclear power development.

This development reinforces the observation that the path to a technological development is not always a straight line.  Modern windmills are, of course, a new incarnation of a very old technology, once used for mechanical power, not electricity.  Nuclear technologies that were once sidelined for a variety of reasons are now receiving renewed interest.  Now, it may well be that solar power for military applications merits another look.  I've been away from it too long to make an educated judgment.  I just wish I'd saved the work I did so many years ago!

  1. I'd be concerned that the soldiers wouldn't have power when they needed it. To me, the way to go would be a flow battery to store power and even out the peaks. The producers, at least, claim 50% power savings. Whether it'd be worth adding a few solar panels to reduce fuel consumption I doubt.
