A Blast From The Past

4 Comments

Ben Bova has a piece in the Naples News that could have been written thirty years ago. In fact, it’s exactly like stuff that he (and I) wrote thirty years ago. The only difference is that I have experienced the past thirty years, whereas he seems to be stuck in a seventies time warp, and I’ve gotten a lot more sober about the prospects for a lot of the orbital activities that were always just around the corner, and probably always will be:

An orbital habitat needn’t be a retirement center, though. Space offers some interesting advantages for manufacturing metal alloys, pharmaceuticals, electronics components and other products. For example, in zero-gravity it’s much easier to mix liquids.

Think of mixing a salad dressing. On Earth, no matter how hard you stir, the heavier elements sink to the bottom of the bowl. In zero G there are no heavier elements: they’re all weightless. And you don’t even need a bowl! Liquids form spherical shapes, whether they’re droplets of water or industrial-sized balls of molten metals.

Metallurgists have predicted that it should be possible in orbit to produce steel alloys that are much stronger, yet much lighter, than any alloys produced on Earth. This is because the molten elements can mix much more thoroughly, and gaseous impurities in the mix can percolate out and into space.

Imagine automobiles built of orbital steel. They’d be much stronger than ordinary cars, yet lighter and more fuel-efficient. There’s a market to aim for.

Moreover, in space you get energy practically for free. Sunlight can be focused with mirrors to produce furnace-hot temperatures. Or electricity, from solarvoltaic cells. Without spending a penny for fuel.

The clean, “containerless” environment of orbital space could allow production of ultrapure pharmaceuticals and electronics components, among other things.

Orbital facilities, then, would probably consist of zero-G sections where manufacturing work is done, and low-G areas where people live.

There would also be a good deal of scientific research done in orbital facilities. For one thing, an orbiting habitat would be an ideal place to conduct long-term studies of how the human body reacts to prolonged living in low gravity. Industrial researchers will seek new ways to utilize the low gravity, clean environment and free energy to produce new products, preferably products that cannot be manufactured on Earth, with its heavy gravity, germ-laden environment and high energy costs.

Cars made of “orbital steel”?

Please.

But I guess there’s always a fresh market for this kind of overhyped boosterism. I think that it actively hurts the cause of space activism, because people in the know know how unrealistic a lot of it is, and it just hurts the credibility of proponents like Ben Bova.

Good Old Reliable

As is often the case, I agree with Glenn. They can have my land line when they pull the phone from my cold dead fingers.

Cells are simply not reliable enough for me to use them for everything, though I put up with it on a trip (when we were with T-Mobile, my cell phone didn’t even work in the house). I wonder how many kids who have grown up with cell phones for voice and texting take their idiosyncrasies and unreliability for granted, because they don’t have that much experience with a reliable and clean line? Plus, during the hurricanes, when all else failed, including power, cell service was out, but I always had phone service plus DSL on my land line. It allowed me to stay on line, by using a laptop and a voltage inverter plugged into the car.

The technology may continue to improve to the point at which I no longer feel the need for a land line, but we’re nowhere near it yet, in my opinion.

Getting Better

The latest installment of “Better All The Time” is up at The Speculist. It’s all pretty good (I found sensation in a bionic arm without sensors fascinating), but I liked this:

Hey, did you notice? The world didn’t end! We get so used to the world not ending that sometimes we take it for granted. But in honor of our not being sucked into a giant black hole or blasted back in time to when our entire universe was nothing but diffuse particles, the Times Online has compiled a list of 30 other time the world didn’t end.

If you like that sort of list, keep this in mind: those thirty days are just a tiny, tiny subset of the total number of days in which the world has not ended. In fact, we are (and I hope I don’t jinx it or anything by pointing this out) batting a perfect 1000 on that score.

Yeah, every day, they tell us the world won’t end, and it doesn’t until one day it does. Which sucks. And there’s no one around to say “I told you so.”

The Latest In Medical Transplants

Eeeeuuuuwwww…:

… Patients who come into the hospital with suspected pneumonia now get an antibiotic within six hours, instead of four hours previously, to allow more time to assess the need for drugs.

One controversial strategy: fecal transplants. For one patient with recurrent C. diff, Kettering suggested a stool transplant from a relative, to help restore good bacteria in the gut. But Jeffrey Weinstein, an infectious-disease specialist at the hospital, says the patient “refused to consider it because it was so aesthetically displeasing.”

To say the least. Though some kinky folks might get off on it. It’s certainly a simple procedure compared to a heart or a kidney.

Some might argue that a lot of folks in Congress have already had the procedure done, except it was transplanted to the wrong location, considerably north of where it was supposed to go.

Of Course It Does

Restricting the top speed on automobiles “seems reasonably sensible” to Matthew Yglesias:

…of course the reason you’re not allowed to go super-fast is that it isn’t safe. A large proportion of car accidents are related to people driving too quickly. Thus, via Ezra Klein comes Kent Sepkowitz’s suggestion that we design cars so as to make it impossible for them to drive over, say, 75 miles per hour.

Clearly spoken as someone woefully ignorant of the cause of accidents, and who probably doesn’t drive much, at least outside a city, or in the west, or in mountains, or on curvy roads where rapid passing is occasionally necessary. Or someone to whom time (at least other peoples’ time) has no value. I suspect that he agrees with Al Gore that cars are intrinsically evil, and wishes that everyone would ride a train, like those enlightened Europeans. It’s similar to the idiocy (and yes, there’s no other word for it) of a double nickel speed limit (something to which even Charles Krauthammer, who doesn’t drive at all) has fallen prey.

Fortunately, most of his commenters take him to school.
