Effect of eclipse on solar farm

Yesterday’s eclipse prompted me to go look at the day’s power production from the University of Illinois’s solar farm.

Just eyeballing the graph, I’d estimate that eclipsing 94% of the sun reduced power production by about 94%.

The solar farm is exactly one mile north of Winfield Village. Jackie and I got a tour of the facility a couple of months ago and I got some pictures besides the one at the top, but haven’t gotten around to writing my solar farm post yet.

Toby’s books on the shelf

We went to Undercover Books in Christensted on St. Croix so my dad could look for Birds of the West Indies (which they had, and which Dad did get a copy of). While we were there, Steve noticed that they had copies of Tobias Buckell‘s books on the shelf, including this signed copy of Xenowealth. (Sorry, Toby, for carelessly covering part of your name in the photo!)

A great bookstore, by the way. Excellent SF section, excellent selection for tourists (books on local history, pirates, etc.), great selection of books for locals, books by local writers prominently displayed. I also really like their tortoise-under-a-book logo.

 

Chart of the Week: Electric Takeover in Transportation

From the IMF blog, a great chart showing the rate at which motor vehicles took over from horses early in the 20th century. Putting current motor-vehicle and electric-car use on the same graph makes a pretty good visual case that we might be as little as 15 years from the cross-over point where half the vehicles on the road are electric.

Greater affordability of electric vehicles will likely steer us away from our current sources of energy for transportation, and toward more environmentally friendly technology. And that can happen sooner than you think.
