I was wrong about Diesel engines being easy to make, as I suggested in my entry for March 5, 2012. Fuel injection, as it turns out, is a bitch. You're trying to divide oil into a multitude of very small droplets of (reasonably) consistent size. Gasoline carburetion, by comparison, is a snap. (Thanks to Pete Albrecht, an automotive engineer, for the reminder.)
I suspect it's easier to produce wood gas (AKA "producer gas") at a small scale than gasoline. In a future where large-scale oil refiners are no more, a Dieselpunk society could power internal combustion engines with wood gas. This has been done a lot around the world, especially during WWII when oil supply channels were disrupted.
This looks like a good book, especially if you're finding it hard to keep track of genre mutation within SFF. Will order and report after reading. (Thanks to Trudy Seabrook for pointing it out.)
We found one of these in a drawer in my late grandfather's workbench after my grandmother died in 1965 and we had to sell their house. I never knew what it was until it made the A-head story on the front page of yesterday's Wall Street Journal , in an article about...olympic sheep shearing. My grandfather lived a quiet life in a modest house on a tiny lot on Chicago's north side. There wasn't a sheep for miles. (I hope he didn't use it to cut my father's hair.)
I've noted some confusion about this: "Retina display" is not an Apple trademark, but a technical term: a display with such high resolution that the eye can't make out individual pixels at typical reading distance. Here's a good explanation of the whole retina display concept. The new iPad certainly qualifies, but it wasn't the first. Asus' Tranformer Prime was there some time ago. Retina-quality displays are made by several vendors, and will eventually appear in other high-end tablets.
The Lytro camera has been mentioned in a lot of places, but here's the first in-depth description I've seen. A camera that allows you to fiddle with the focus after the shot is taken is FM, if you know what I mean. I ditch about a third of my digital photos (mostly taken in bad light) for focus problems. It's an awkward form factor, but if it's the first of it's kind, I'll assume the next one will fit the hand a little better.
The mad scientist in me cried out when I saw this. I need a castle. I need a kite. I need a monster.
