Cool! I'd only heard of it in the context of solar/wind power, but it appears quite widely used.

How can you say that was a drag? That was poetry that was; sheer poetry. :D

The dude was glibly talking out of his backside. You could see he knew right away that he'd stepped into a leaky boat, and had to start bailing fast. In my case, boredom won out over Schadenfreude.
