Are Stirling engines the future of solar power?

Yesterday's 'science & technology posting' looked at 'electric vs hydrogen cars':

The technology has been around for some time now:

But it's just gained a huge push from NASA:

And NASA has been interested in the technology for some time now:

A second type of solar-powered Stirling engine was patented by NASA on August 3, 1976 which employed the use of solar energy in order to freely pump water from a river, lake, or stream.[3] The purpose of this apparatus is to “provide a low-cost, low-technology pump having particular utility in irrigation systems employed in underdeveloped arid regions of the earth…[using] the basic principles of the Stirling heat engine.

Although back on earth, a nuclear source is not necessary:
