Armadillo claims X Prize

The rain cleared off long enough earlier this evening, at Caddo Mills northeast of Dallas, for Armadillo Aerospace to claim the X Prize Foundation’s million dollar award for a private rocket capable of taking off, flying for a hundred eighty seconds and landing precisely on a simulated lunar surface. Two videos here show the vertical takeoff and vertical landing rocket doing the trick.

Another blow for ‘peak oil’

Before it was in North Dakota. Now it’s deep under the Gulf of Mexico. Whether we need it or not is one thing. (Although it would be good not to be so dependent on dictators and absolute monarchs for it.) But the idea that we’re running out of it is pure baloney.

Solar energy from the black

It’s a been a topic of debate for many years and, so far, all we’ve done is talk about it. The Japanese appear to be ready to put $21 billion where their mouth is when it comes to collecting solar energy in space and beaming it down to the surface. They say they’ll be able to power 249,000 homes. Makes a lot more sense than ruining a desert ecology with solar collectors. What do you want to bet the UN calls it too dangerous and tries to stop them?

Specious argument

I have often, foolishly, commented that the climate modeling of anthropogenic global warming can’t be accurate since weather forecasting is so fallible. It’s a poor argument, as Andrew Dessler at Texas A&M shows:

"Predicting the weather is like predicting what the next roll [of the dice] will be. Predicting the climate is like predicting what the average and standard deviation of 1000 rolls will be. The ability to predict the statistics of the next 1000 rolls does not hinge on the ability to predict the next roll. Thus, one should not dismiss climate forecasts simply because weather forecasts are only good for a few days."

On the other hand, it’s a good argument to say that the climate models are too weak to be trusted, because the physics of the atmosphere isn’t fully understood. In other words: garbage in, garbage out.

Spin

I read the sequel Axis first, only because it was available at the library and Spin wasn’t. Now I await Robert Charles Wilson’s conclusion, tentatively titled Vortex. Spin is pretty incredible. Apocolyptic but plausible. If you read a lot of scifi, I mean. The idea that a mystery race of sentient biotech machines would seek to save Earth by enclosing it in a living membrane, then speeding up time beyond it.

But it’s the coming-of-age, three lifelong friends’ saga and love story between two of them that sticks with you. The scifi binds them, beginning with the night in their puberty when the stars disappeared (thanks to the membrane) and only reappeared when they were in their forties. A bit heavy on the government conspiracy stuff for my taste. As I have said elsewhere I believe in the government’s innate incompetence, not it’s all-powerful whatever. And the idea that peak oil is our doom is tiresome. But, as I say, neither of those subjects dims the human story, which lingers yet in my mind.

Axis was a worthy sequel, with just enough of a hint about the original folks to send me out in search of Spin, which was reward enough for the trouble. Second books in trilogies usually pale beside the first ones, but Axis didn’t. Quite. The human tale was less compelling than in Spin, but worth the read. Now I await Vortex, curious to see how the sentient biotechs, called the Hypotheticals, will wrap it up.

Morning Glory Clouds

You don’t have to leave the planet to find weirdness. These tube clouds can move at sixty clicks an hour with no discernible wind to push them. They form every spring over Australia. The Seablogger says we also get them over the Midwest (and elsewhere in the world) the morning after a night of severe thunderstorms.

Hubble’s Ultra Deep Field

Get out your 3D glasses for a stirring, and a bit humbling, animation of about ten thousand of the other hundred billion galaxies out there in the black. More here.
