Snow-Melting Satellites

17 Comments

Patrick Collins, a PhD economist who lives in Japan, has been a long-time promoter of space tourism, but he has also been interested in solar-power satellites. Many have promoted them as a means to mitigate greenhouse gases, but three years ago, he presented a paper in Nagoya on their use in preventing the next glacial advance, which would be much more catastrophic than any of the climate frights conjured up by the warm mongers. He writes:

The webmaster of spacefuture.com [presumably, Peter Wainwright] refuses(!) to put this paper into the Space Future library which we founded together! Living and working in NYC seems to have made him “politically correct” (i.e. unscientific) – and also “warmist”! This despite the fact that any arguments that once existed for the theory that human emissions of CO2 could lead to catastrophic “global warming” (now morphed into “climate change”) have been totally destroyed by ever-growing scientific evidence – including notable work by Burt Rutan.

This evidence has grown by leaps and bounds in the three years since this paper was written. For a taste of the power of private citizens dedicated to scientific truth, and armed with the Internet and Freedom of Information laws, wattsupwiththat.com is hard to beat.

When we wrote this paper, neither of us had read Fallen Angels, in which Larry Niven, Jerry Pournelle and Michael Flynn – back in 1991 – prefigured both the key ideas: that the coming of the next Ice Age is a far greater threat than any possible warming, and that solar-generated microwave beams from orbiting satellites offer a unique means of combatting the spread of glaciers. NB it will require a massive “crash program” to ramp production up to a scale that could save western civilisation – a cool 1 million square kilometres of solar panels in various orbits! Sadly they were also prophetic about the degeneration of the US government. Perhaps holding back the glaciers could become the trigger to wake people up and develop space at last? Their book receives honourable mention in the follow-up paper being published soon.

I’ve uploaded the paper to my own site, for anyone interested, despite Peter’s truculence in that regard.

Too Little, Too Late

28 Comments

Wayne Hale continues to recall the events of a decade ago, when Columbia was lost, here, and here. And as I suspected at the time, they took the attitude that Gene Kranz did in the movie:

Jon Harpold was the Director of Mission Operations, my supreme boss as a Flight Director. He had spent his early career in shuttle entry analysis. He knew more about shuttle entry than anybody; the guidance, the navigation, the flight control, the thermal environments and how to control them. After one of the MMTs when possible damage to the orbiter was discussed, he gave me his opinion: “You know, there is nothing we can do about damage to the TPS. If it has been damaged it’s probably better not to know. I think the crew would rather not know. Don’t you think it would be better for them to have a happy successful flight and die unexpectedly during entry than to stay on orbit, knowing that there was nothing to be done, until the air ran out?”

I was hard pressed to disagree. That mindset was widespread. Astronauts agreed. So don’t blame an individual; looks for the organizational factors that lead to that kind of a mindset. Don’t let them in your organization.

As I wrote:

…you’re asked to make an assessment, in the absence of any data except a launch video showing some insulation hitting the vehicle, as to whether or not the damage could be catastrophic. Others around you, whom you respect, are saying that it won’t be. You have a bad feeling, but you can’t prove anything with the available data.

What do you do? What’s the benefit, given that there’s no action that can be taken to alleviate the problem, in fighting to get people to recognize that we may have a serious problem?

Moreover, suppose that we do believe that there’s a problem.

Do we tell the crew? What can they do, other than make peace with their God and say goodbye to their families?

Add to that the fact that it would disrupt the mission, perhaps for nothing, and sadly, deliberate ignorance looks appealing.

Say What?

What does this mean?

The original Panama Canal was a revolution in geopolitics and economics; before it was built, the sea voyage was shorter from London to San Francisco than from New York to California…

Ummm, last time I checked, San Francisco was in California, and that was true even before the canal was dug. How could it have been a shorter distance from London to there, than from New York to there (or to southern California)? Both trips would involve going around the Horn (or taking the long way round the other way). Does anyone know what Professor Mead is saying here?

Pretend Gun Control

18 Comments

Frank J. has a great idea that should make everyone happy, ignorant and knowledgeable alike:

…What we can do is pass a law banning a bunch of made-up things that sound scary, and many gun control proponents already have great ideas along this line. For instance, I read a column in which Howard Kurtz mentioned a ban on high-magazine clips — we can certainly do without something that nonsensical. And I’ve heard the press before mention armor-piercing hollow points and plastic guns (actually, I think we already banned that made-up weapon in the ’80s). And as long as the NRA and Wayne LaPierre go apoplectic about it (“This ban on sorcerer-enchanted guns is just a slippery slope toward eliminating all witch-hexed weaponry!”), gun control proponents won’t know the difference between this and actual gun control. And this will help protect our most vulnerable people out there: politicians. Because long after the gun control advocates move on to other things, like who they want to tax next, gun owners will still be annoyed by any actual gun control legislation. One of the greatest fears politicians have is seeing an angry guy with lots of guns charging down the street, because they know he’s probably on his way to commit an act of voting.

Of course, with this idea, absolutely nothing will be done to keep criminals and madmen from obtaining guns, but that’s the effect of every other gun control law, so we’re just reaching this end in a much cheaper and less messy fashion.

I think you could probably even get it through the House. And the enforcement costs would be zero.

Carbon Nanotubes

5 Comments

This looks like it would make a useful material for an electrodynamic tether:

Working with Teijin Aramid, the Rice group has now made carbon-nanotube fibers that have more of the properties of individual nanotubes. They have an electrical conductivity close to copper’s, but are much stronger. They’re not quite as strong as conventional carbon fibers, but they’re much less brittle. And they’re more thermally conductive than metal or carbon fiber. That means nanotube fibers could replace these materials in existing applications in aerospace and electronics, and enable new technologies that take advantage of the fibers’ unique combination of strength, flexibility, and thermal and electrical conductivity. Pasquali envisions washable electronic textiles, lightweight wiring for planes, and eventually, more efficient wires for the electrical grid.

Cool.

The Defense Budget

51 Comments

How much can we cut?

In addition to the points that Megan makes, a lot of the Pentagon budget is wasteful, for the same reason that a lot of NASA’s is — because the lawmakers on the committees overseeing it like it that way. But the other problem is that we can’t always predict what we’ll need, and in that sense, defense spending is like advertising — only half of it is effective, but no one knows which half.
