Now here’s what I like to see.

“High-tech marvels, the solar dishes look like three-story-tall mirrored flowers atop steel stems. But at the heart of each dish is a very old-fashioned invention: a Stirling engine, patented by a Scotsman in 1816, decades before the diesel or internal combustion engine.
The cutting edge of renewable energy is littered with long-established ideas such as the Stirling. From generating power from the wind to harvesting liquid fuel from algae, some of today’s most promising new technologies are actually quite old.”
May I use this beautiful photo of Stirling in my book about Solar Energy?
