Give The Lunar Solar A Rest

One of the presentations at the Space Investment Summit was on Lunar solar power. Solar satellites were also referred to. One presentation noted that if a government agree to buy solar at $0.85/kwh (about a 900% subsidy) that space solar would pay. Great. You can make $50 billion if they give you a $70 billion subsidy. Hand me a glass of ethanol.

My previous best efforts on solar are here, here, and here.

I think there is a fairly simple case against. Grant that space solar is 4x as efficient per kilogram as Earth solar. Ignore the fact that people want more power during the day than at night. Grant that we can take raw silicon and turn it into solar cells with minimal remote human input. Grant that we can beam it. Ignore that if we import solar power in quantity that the price of coal and uranium will drop until they are competitive again as fuels.

Can’t we just set one of the ‘bots that will build the cells loose in an Earth desert? Doesn’t it require the transportation cost to space be on the order of 4 times the manufacturing cost for space solar to be economically effective? Even if we are just talking about the regolith eating robot, don’t we have to get transportation cost down to three times the cost of producing a sand eating robot and letting it loose in the desert? Am I missing something? I think this argument means space solar will never be competitive.

Space Science

Space Science Bull

Thomas B. Pickens III gave the luncheon speech at the Space Investment Summit yesterday. He thinks that SpaceX and Rocketplane-Kistler are the “Toyota trucks” of the space infrastructure and that Space Hab will make a good business of packing science payloads to send to the Space Station. He is interested in ISS racks but can do free floating experiments and also work with Bigelow. I asked him afterwards if doing his “due diligence” as a board member before taking over as CEO he talked to the customers. He said that every customer said that they were interested if it were cheaper, more reliable and standardized.

I think that this market may not be as big as Bigelow and Space Hab are hoping. It remains to see if a business can be made. The Bull I prefer is Space Tourism. Space Hab did say they could do logistics missions too. Glad to have you as part of the industry, Thomas B. Pickens. Best of luck.

Economics

Free Market for Loans

New York Times says in an editorial that student loans should be subject to sunshine laws, careful policing and ethics rules that make it a crime to take money for access to colleges. This is misguided. Colleges will voluntarily step forward to show that their processes are clean now that there is focus on the issue. Those that don’t should be spared the regulatory burden. Students will go to the school that gives them the best overall package. Competition will steer students to the schools with the best policy–taking into account both student loan rates and what the school does less of due to the way it administers the loans.

Political Commentary

More On Infantilization

On Monday, I wrote:

Here it comes. Now they’re going on about “the children, won’t someone think of the children“? Someone on Cavuto is demanding to know what they’re doing for “the kids.” Are they being kept warm, are they being fed, are they getting the grief counseling they need?

These “kids” are college students. Almost all of them are of the age of majority. They’re the same age as the “kids” who are off fighting for us overseas, who are seeing things just as horrific, or more so, every day. Yes, one doesn’t go off to an idyllic campus in the western Virginia mountains with the expectation that they’ll have to deal with something like this, but they’re not kids. In every society up until this one, they would have been considered adults, and many of them would have already been married (or not) and raising families. The notion that we should treat them like grade schoolers, for whom we are responsible for feeding, and heating them, is ludicrous. Yes, they’re upset, but I’m pretty sure that they’re still capable of feeding themselves, and finding a blanket, if shooting people somehow caused the heating systems on campus to break down. If I were one of them, I’d be insulted and appalled at this kind of stupid, stupid commentary.

Today, Mark Steyn expands much more eloquently on that theme, and on our culture of passivity:

The students at Virginia Tech were grown women and

Report From The Front

Professor Chris Hall, former aerospace engineering blogger, but now department head at VPI and too busy to blog, checks in with a message:

Dear Friends and Colleagues,

I have heard from many of you throughout the last 24 hours. I’m sure I speak for the entire department, when I say that we thank you for thinking of us and for your many thoughtful notes. It means a lot to us.

As far as I know there were no casualties from the department of Aerospace and Ocean Engineering. We won’t really know that until the names are released though. My son is a sophomore in Engineering Science and Mechanics, which is the department that Occupies most of Norris Hall. He is safe, but his undergraduate research advisor was one of the fatalities.

The departments of Engineering Science and Mechanics and Civil and Environmental Engineering lost three good men, and there are several folks in the hospital. The three fallen professors are Liviu Lebrescu, Kevin Granata, and
G.V. Loganathan.

Liviu was an internationally known mechanician and was teaching a junior-level course on Solid Mechanics yesterday morning in Norris Hall. I did not know him well, but occasionally chatted with him about his home country of Romania.

Kevin was a young professor with a young family. His field was biomechanics, and my oldest son chose to major in ESM because he wanted to work in Kevin’s lab. My son, Duncan, a sophomore, has worked in Kevin’s biomechanics
lab for the past year. I thoroughly enjoyed Duncan’s stories of how Professor Granata was teaching him how to program nonlinear controllers for inverted pendula. I know Duncan will miss those lessons.

G.V. was an award-winning professor of environmental engineering, whose expertise was in water resources. Most recently he won the university’s prestigious Wine Award for excellence in undergraduate teaching.

Again, I thank you all for your kind messages. I will let you know more when I know more. Please feel free to forward this email to friends and colleagues.
