Singularity 101
Solar System Day
Regular readers know that I hate the earth and the environment.
Well, not really, but I’d imagine that some of the more deluded among them believe that. And I am opposed to many so-called environmentalists. But it’s not an anti-environment position so much as an anti-anti-humanity and anti-anti-free market position.
So I do have trouble getting into Earth Day. I find the notion far too blinkered and unimaginative.
Yes, earth is special and, as we learned over forty years ago (shortly before the first Earth Day), looks like a very precious and fragile jewel against the black background of an unimaginably vast, sterile and hostile universe.
But it’s just one planet of uncountably many, and we don’t just live on a planet, we live in a solar system, a galaxy, a universe. In fact, while there’s an implicit recognition of this in the worship of the sun by the renewable energy types, they’re insufficiently open minded about the use of the rest of the system as a source of resources whose harvesting would be much gentler on the planet than mining them here, if it could be done cost effectively.
I’d like to see Earth Day used as a platform to focus a lot more attention on the environmental benefits that space technology has brought us over the past half century, from data gathering on deforestation and pollution, communications that allow less business travel and more telecommuting, to space-based navigation that saves fuel and lives. I’d also like to see consideration of the even greater future potential for saving the planet via space.
I actually do share the goal of the anti-humans of wanting to reduce the environmental burden of humanity on the planet, and I don’t even necessarily object to the goal of reducing the terrestrial population, as long as we can dramatically increase the extraterrestrial human population, because I’m one of those people who think that human minds are the ultimate resource, and that you can’t have too many of them. But the way to achieve that goal is to open up space, not to simply reduce the human population on earth, by whatever means necessary (and many of these folks think that end will justify any means).
Back in the seventies, many of the L-5ers were hippies who recognized the peaceful potential of space colonization to gently depopulate the earth and make it into a giant natural park, with the vast bulk of humanity living and producing off planet the wealth, via industrial-intensive processes, that would make such a thing affordable. I wasn’t a hippy, but I thought then, and still think, that a wonderful ultimate goal.
But the means to achieve it are not more constraints and taxes on current energy use, or population. It is to deploy technologies that can actually achieve the goal — nuclear, molecular manufacturing, fusion (if we can do it), and low-cost space access, which might eventually make space solar power and extraction of other extraterrestrial resources for use on earth economically feasible.
Golda Meir once said that there would be peace in the Middle East when the Arabs started to love their children more than they hated the Jews. Similarly, the planet will be saved when many of the watermelons who claim to care for it start to love it more than they hate humans, freedom, individualism and technology.
[Thursday morning update]
Last week the Environmental Protection Agency did bravely move forward by finding that things like smokestacks and breathing — or anything related to greenhouse gases — endanger the public health and welfare. And since the EPA can now regulate CO2, it can have a say in nearly everything we do with little regard for silly distractions like economic tradeoffs…
…What’s worse than the EPA grabbing power over CO2? Well, leading Luddite and Congressman Henry Waxman is worse. His proposal sets carbon reduction goals of 20 percent by 2020, 42 percent by 2030 and 83 percent by 2050, and, with cap-and-trade, effectively nationalizes energy production.
This incremental destruction of prosperity is probably going to have to be modified as soon as citizens get a taste of reality. But how could any reasonable or responsible legislator suggest an 83 percent cut in emissions without any practical or wide-scale alternative to replace it, or any plan to pay for it all?
Well, that assumes that Henry Waxman is reasonable or responsible, when the available evidence indicates otherwise.

The Achilles Heel Of Aging
Most people aren’t aware of the recent scientific breakthroughs in life extension technology, but here’s a good update:
In 2004 my lab teamed up with Dr. Rafael de Cabo at the National Institutes of Health to see if resveratrol could improve the health and extend the lifespan of mice. When middle-aged mice were fed a low-fat diet, resveratrol delayed diseases of aging but did not extend lifespan. When fed a high-fat diet, mice on resveratrol got chubby but stayed healthy — they were less susceptible to diseases we associate with obesity, like type II diabetes. And with a sufficient- win a Nobel Prize. ly high resveratrol dose, they burned enough fat to stay lean. What’s more, the resveratrol mice on the high-fat diet ran twice as far on a treadmill as their unmedicated counterparts, and their remaining lifespan after treatment began increasing by an average of 25 percent compared with the high-fat controls. Notably, in both the obese and the lean mice on resveratrol, there was the clear physiological signature of calorie restriction.
The trouble is, while resveratrol is found in many foods, it is present only in very low concentrations. Someone wanting to get a resveratrol dose equivalent to what we used in our mice studies would need to consume hundreds of bottles of red wine each day. Resveratrol has served its purpose, proving the possibility of inducing the physiology of dieting and exercise with a small molecule. Now pharmaceutical companies are working on synthetic molecules that are thousands of times as potent as resveratrol: The race to develop a drug that targets sirtuins is on, though the longterm effect of activating sirtuins in humans requires further research. If the mice studies are anything to go by, the side effects of these drugs could include protection from multiple illnesses, including heart disease, osteoporosis, cataracts, and Alzheimer’s.
Bring it on. I’m all in favor of this, which is one of the reasons that I’m not a conservative.
I Got Ripped Off
Over forty years ago, we stopped at the Four Corners National Monument on a family vacation, where I got to have one limb in each of the four states simultaneously. Well, it turns out that the plaque is off by two and a half miles. So all those tourists were in Colorado the whole time.
I’m not sure whether to blame George Bush, or Barack Obama.
Space Nuclear Waste Disposal
When I wrote that piece about Three-Mile Island the other week, I forgot to mention my own recollections of the event. It was interesting timing, because it happened in the middle of a senior space systems engineering project that I was involved with at the University of Michigan. It was an annual course taught in the Aerospace Engineering department, required for Aerospace majors, which I took as an elective (though it wasn’t my major, I took many courses there, including several graduate ones, tailoring my own astronautical engineering degree, but without the emphasis on aeronautics). The course was taught by Harm Buning (who died only three years ago — I really ought to write about him some time). The project was to figure out how to dispose of nuclear waste in space. This was a couple years before the Shuttle had its first flight, and we still believed the hype about its cost and safety, so it was the assumed launch vehicle, but the question was what to do with the stuff once it was in LEO.
Having been pretty heavily involved with the L-5 Society (I had actually spent a semester the previous year volunteering at the HQ in Tucson, and had met people involved with the MIT mass driver work, including Henry Kolm and Eric Drexler — the people in that now-classic picture are, from right to left, a twenty-four year-old bearded Eric wearing a Maxwell’s equations teeshirt (one of which I also had at the time), Henry, Gerry O’Neill, someone unknown to me, and Kevin Fine — geek and space enthusiast city — I could write a sad book titled “We Were Space Enthusiasts, And Young…), I suggested that we use a linear synchronous motor to propel it out of the solar system. The class adopted the idea, and we came up with a crude systems design (about what you could expect from college seniors for such a complex project). It was in the middle of the project that TMI occurred, making it seem even more relevant.
The university seems to have put many of these older (typed by department secretaries– no word processors back then) reports on line, including this one. I’m sure I have a dead-tree copy somewhere, but it’s nice to see it on the web. It’s been a long time, and I was distracted at the time because my father had his second heart attack in April of that year, and died a few weeks later. Due to time missed, I had to finish up my sections early in the summer to avoid an Incomplete for the course, so I don’t remember how much of it and which parts I wrote, but it was quite a bit of it (at least the orbital mechanics and the dynamics of the payloads in the accelerator, and how much wall play they would have to have). Dave Steigmann wrote a lot of the structures section, I think. The report says that it’s authored by Kevin Blankinship, but he was probably just final editor, because he was officially the team project manager. One of the things that this course taught was not just engineering, but how to work as an engineering team (including managing with the politics and personal interactions). These were…interesting. I won’t say any more than that, to protect the guilty, whoever they all may be. 😉
Anyway, is it feasible? Probably not, but it was a good project for the purpose of learning how to consider all aspects of a space system, and project teamwork.
[Update a while later]
The project name was pretty good acronymery. I don’t recall whether it was mine, someone else’s, or the result of a brainstorming session. But it was Project NEWDUMP (Nuclear Energy Waste Disposal Using Mass-Driver Propulsion).
For anyone who is willing to read the thing, it is probably entertainingly rife with howlers, from the perspective of three decades later. This one on page four jumped off the page at me:
The Space Shuttle has substantially reduced the cost of space transportation since the Apollo project, with possible improvements for further economy.
Note the tense, and not also that this was written about two years before first flight.
More SPS
Technology Review has a story about the Solaren/PG&E deal, which answers questions some have had in comments about beam intensity and aiming.
Traffic Camera Fraud
Holman Jenkins writes about the war on short yellows.
How Do The Numbers Work?
Sorry, but I just can’t buy this:
PG&E is pledging to buy the power at an agreed-upon rate, comparable to the rate specified in other agreements for renewable-energy purchases, company spokesman Jonathan Marshall said. Neither PG&E nor Solaren would say what that rate was, due to the proprietary nature of the agreement. However, Marshall emphasized that PG&E would make no up-front investment in Solaren’s venture.
“We’ve been very careful not to bear risk in this,” Marshall told msnbc.com.
Smart move.
Solaren’s chief executive officer, Gary Spirnak, said the project would be the first real-world application of space solar power, a technology that has been talked about for decades but never turned into reality.
“While a system of this scale and exact configuration has not been built, the underlying technology is very mature and is based on communications satellite technology,” he said in a Q&A posted by PG&E. A study drawn up for the Pentagon came to a similar conclusion in 2007. However, that study also said the cost of satellite-beamed power would likely be significantly higher than market rates, at least at first.
In contrast, Spirnak said Solaren’s system would be “competitive both in terms of performance and cost with other sources of baseload power generation.”
I just can’t see how. Unless there are going to be many satellites, the system has to be in GEO to provide baseload power to any given region on earth. They talk about putting up a 200 MW system with “four or five” “heavy lift” launches (where this is apparently defined as 25 tons).
Suppose the conversion efficiency of the cells is a generous 30%, the DC-MW conversion is 90%, the transmission efficiency is 90% and the MW-AC conversion efficiency is 90% (generous numbers all, I think). That gives an overall efficiency of 22% from sunlight to the grid. The solar constant in space is 1.4kW/m
That doesn’t include the mass of the conversion electronics, basic satellite housekeeping systems (attitude control, etc.) and the transmitting antenna, which has to be huge to get that much power that distance at a safe power density.
So even ignoring the other issues (e.g. regulatory, safety studies, etc.) that Clark mentions, I think this is completely bogus until I see their numbers. And probably even then.
What The Tea Parties Are About
This is both an interesting, and scary graph. The most important thing to me is not just the sheer magnitude of the Obama deficits, but the respective trends of both administrations.
Note that the Bush deficit was decreasing every year until 2008, when it got hammered by the TARP (at least I’m assuming that’s the cause, though it could also be a result of the slowing economy throughout the year, not to mention Congressional spending increases under the Democrats starting in late 2007). Note also that this was happening despite the evil Bush “tax cuts” (which obviously weren’t really tax cuts — they were just tax rate cuts that actually were reducing the deficit, despite the out-of-control spending by the Republican Congress).
In contrast note that the Obama plan is ever-increasing deficits after 2012, whether you believe administration or CBO projections. And though they decrease in the near term, they never get as low as the worst Bush deficit before they start to sky rocket in the teens. This, simply put, is fiscal insanity. And increasing taxes on “the rich” (as they’d surely love to do if they could get away with it) isn’t an option. There simply isn’t enough money there, and if there were, it would tank the economy even more, with even larger deficits from reduced tax receipts and automatic increases in non-discretionary wealth transfers. Also, estimate the integral under the curve. That’s an accumulating debt, with an ever-increasing proportion of the deficit going to interest, particularly when people become reluctant to loan money to a budding Weimar at low rates.
People who will be protesting on Wednesday won’t be protesting against a party. They’ll be protesting against a government completely out of control. But unfortunately for the Democrats and the left, they will be seen as the much larger part of the problem, because the Republicans are now at least giving lip service to reduced spending and reduced government. But they’re going to have to work very hard to live down their spending spree of the “compassionate conservative” (read, “progressive lite”) Bush years.
[Evening update]
“Liberal doughboys afraid of tea parties.”
Liberal bloggers and media groups can’t get the Tea Party phenomenon out of their heads. It wasn’t supposed to be this way, to them. Ordinary people getting together to protest against the liberal establishment. There is a cognitive disconnect. There must be a plot; the vast right-wing conspiracy at work.
So true to form, Media Matters sounded the horn that this was not a real protest, it’s a Fox News segment. Kind of a made for T.V. reality show, with a cast of tens of thousands. Think Progress joined in with “Spontaneous Uprising? Corporate Lobbyists Helping To Orchestrate Radical Anti-Obama Tea Party Protests.”
And the netroot blogosphere heard the call. FireDogLake proprietor Jane Hamsher posted “What Part of ‘FNC TAX DAY TEA PARTIES’ Don’t You Understand?” Hamsher also promoted “citizen-organized protests” which were unlike the “Fox-organized” Tea Parties; I guess she didn’t catch the irony of promoting counter-protests to protest other people promoting protests. Anyway, almost no one showed up for the counter-protests.
Gee, I think I have one of those in comments.
[Monday morning update]
More tea-party panic:
What’s the big deal? ACORN, MoveOn, and Soros get to pull puppet strings year after year, and that’s ok. But God forbid Fox News puts so much as its imprimatur on Tea Parties! No way! That’s too sinister, too insidious; and makes the whole movement illegitimate and inauthentic. Whatever…
Jane Hamsher and Oliver Willis are probably asking “Who the hell are this Tea Party bunch? Where did they come from?” I’ll tell you who they are, Jane and Oliver. They’re your worst nightmare: they’re small-governmenters first and party-loyalists second.
And we’re not laughing with you, Jane and Oliver. We’re laughing at you.

[Update a few minutes later]
More on Crazy Jane and the other panicked and paranoid leftists (like my commenter):
She’s implying because freedomworks listed the Texas Tea parties and Dick Armey is part of freedomworks that the Tea Parties, Houston in particular, are being organized by “Corporate lobbyists”. Houston Tea Party has never spoken with Freedomworks or Dick Armey, though we do know that Freedomworks has offered legal advice to different Tea parties, we’ve not sought it. None of that should imply they are running the show unless you go to the point of just making stuff up.
The “Corporate lobbyist” line is a laugh. Felicia is a local Mother of two who worked with some local grassroots groups like Raging Elephants. I was someone who was trying to be apolitical the past 4 years until I took a good look at was going on, and I was laid off last week and currently unemployed. There are other organizers and volunteers with us. None of them come close to the description “Corporate Lobbyist”.
And no, this woman is nuts, Fox News is not organizing the Tea Parties, they’re just jumping on board (like a lot of people are trying to). But she’s seeing Dick Armey and Fox News as the boogeymen in the closet…
So… I’ve had my LMAO moment for the day. How about you? 🙂
Edit: More on this silliness:
If we’re being organized by “corporate lobbyists” then where the heck is my check?
Yeah, me too. How do I get in on this hot “corporate lobbyist” action?
