Desert Leap writes: The Washington Post reports a new study that suggests it is more environmentally friendly to fly rather than to drive. Analysis from the University of Michigan Transport Research Institute found that driving uses 57% more energy than flying per passenger mile. This is largely due to the number of occupied plane seats increasing while passengers per car decreased.
Of course, "results may vary" for individual trips depending on many factors, such as distance flown (long flights are more fuel efficient) and the kind of car and how many riders.
One factoid is interesting, it takes 4,211 BTUs per person mile to drive. This number will fall as we switch over to electric vehicles. For example, a Tesla Model S takes about 1,100 BTUs per vehicle mile. Will future aircraft be able to also make the switch to electric?
Desert Leap writes: I was taught there are three ways to create wealth: grow it, mine it or manufacture it. Bankers take wealth in exchange for financial services; they redistribute wealth but do not create it. So, it should come as no surprise that business schools (a.k.a. banker factories) actually inhibit productivity growth.
I supported NASA's "If we build it, they will come." because we needed to establish heavy lift as a foundation to do any manned or heavy robotic exploration and exploitation of space. How about a space plane for low earth orbit and a mini space station for the Moon and Mars.

Researchers have long thought that these various examples of “psychological distance” are represented by some of the same circuits in the brain. A new brain-imaging study strongly bolsters the idea, finding that certain patterns of neural activity underlie all of our judgments about distance — whether in space, time, or the social realm.

The prototype is a part of The Kvasir Project and the goal of the prototype is to generate roughly 100 watts of electricity from a single device. This concept is interesting because multiple devices can be implemented along a single storm drainpipe as long as the building is more than one story high. More information about the Kvasir Project and the prototype can be found at the kvasir project website.

'Ukrainian riot police appear to be having trouble deciding who to beat up. BBC is reporting that police stopped a bus heading to Kiev and assumed that they were more protesters. So, they did what has become standard operating procedure for Ukrainian police: they proceeded to savagely beat the occupants.'

Nate Silver's 538 blog (http://fivethirtyeight.blogs.nytimes.com/) is much more interesting. His model takes into account polls (which he adjusts based on past accuracy) as well as economic factors. Nate is currently estimating a probability of an Obama win at 77%. Probably a much more accurate assessment than an estimate of 98%.
Nate Silver prediction for the 2008 presidential popular vote percentages was within 0.1% of the actual results.

The company had been hurt by the elimination of European subsidies and recently idled their manufacturing plant because of excess inventory. Thin-film photovoltaic companies face stiff competition from lower-cost polycrystalline solar panels, especially those from China.

This revolution will be more widespread because this is software that writes its own hardware. Forty percent of Dupont's earnings today come from the life sciences. It's going to change everything.'"
Desert Leap writes: Harold Camping, that minister that predicted the Rapture would occur last May 21, is reminding us that the world will "probably" end on Oct 21, this Friday. Mr. Camping must believe in a cruel and vengeful god; a benevolent god would end the world on Monday and let us enjoy one last weekend.
