TREV: Thousand-Year-Old Windmills Still Work

What's the longest you've been able to keep a cellphone? One year? Two years? It's funny how they seem to stop working just before your contract expires. Like a lot of things these days, they're not exactly built to last. At the risk of coming across like your cranky uncle who always says, "They don't make things like they used to," I'm posting this Totally Random Educational Video (TREV) about 1,000-year-old windmills in Iran that are still being utilized to grind wheat into flour.

The windmills at Nashtifan are among the oldest in the world and are thought to have been designed between 500 and 900 A.D. They were built in a part of Iran where forceful winds blow steadily, sometimes reaching hurricane strength. And the best part is that these windmills couldn't be more environmentally-friendly. Perhaps ancient technology is the solution for a world trying to go green.
