Sorry, but it's not. That's from Alchemy Gothic's Steampunk line, and the "mechanics" of it are completely decorative- it's just a standard quartz movement. Looks awesome, but the whole solar turbine bit is just a clever backstory. Looks like the "Treehugger" site that story came from didn't look deep enough, and Dvice didn't double check.
This Alchemy retailer on eBay has more pics, and the disclaimer the news sites missed. As I said, it
looks great. Too bad that's as far as it goes.
