If We Can Put A Man On The Moon…

2 Comments

…why can’t we kick the fossil fuel habit? Well, we can, but not the way we put a man on the moon, and certainly not within a decade. On the thirty-ninth anniversary of the first landing, I explain.

[Afternoon update]

It’s interesting to note that the original landing was on a Sunday as well. I don’t know how many of the anniversaries have fallen on a Sunday, but I would guess five or so. It’s not too late to plan to commemorate the event with a ceremony at dinner tonight, with friends and family. Also, a collection of remembrances here. If you’re old enough to remember it yourself, you might want to add one.

The End Of The World

2 Comments

Ron Bailey reports.

Well, OK, it’s just a conference on the subject. Which isn’t as interesting, but a lot less scary.

[Saturday morning update]

We have met the enemy, and he is us:

“All of the biggest risks, the existential risks are seen to be anthropogenic, that is, they originate from human beings.”

All the more reason to get some eggs into baskets other than this one. Also, the rise (again) of the neo-Malthusians. It’s hard to keep them down for long, even though so far, they’ve predicted about five out of the last zero world overpopulation crises.

Empirical Evidence At The Nanoscale

16 Comments

This is pretty damned cool:

Chan said the experiment shows that it is not possible to simply add the force on the constituent solid parts of the plate — in this case, the tines — to arrive at the total force. Rather, he said, “the force actually depends on the geometry of the object.”

“Until now, no significant or nontrivial corrections to the Casimir force due to boundary conditions have been observed experimentally,” wrote Lamoreaux, now at Yale University, in a commentary accompanying publication of the paper.

I don’t know what it means for the singularity, but molecular manufacturing seems to be moving along nicely. Tony Snow’s death was sobering for me, because we were very close to the same age. Fortunately, I don’t have the genetic time bomb that he did, though my family’s heart history is worrisome. All I can do is do what I can do, and hope that things will come along.

Energy Versus Space?

2 Comments

Jeff Foust wonders if new government energy initiatives will crowd out space budgets.

Maybe. His piece reminds me of an idea I’ve had for an essay on why energy independence isn’t like landing a man on the moon.

In fact, I had a related comment over at Space Politics this morning, in response to a comment from someone named…Someone…that cost-plus contracts are a proven means of success in space:

I know alt.spacers see cost-plus as some sort of ultimate evil. But recognize its been successful in the past, from the Saturn V to the Pegasus. And the X-33 would likely have been finished and test flown if NASA had used its traditional cost-plus approach instead of the fixed price model they used. If NASA had funded the X-33/VentureStar under the same procurement model as the Shuttle it would be flying today.

To which I responded:

But recognize its been successful in the past, from the Saturn V to the Pegasus.

Only if by “successful,” you mean it eventually results in very expensive working hardware. Not to mention that Pegasus was not developed on a cost-plus contract.

And the X-33 would likely have been finished and test flown if NASA had used its traditional cost-plus approach instead of the fixed price model they used.

Perhaps. At a cost to the taxpayer of billions. And probably a radically different vehicle than the one originally proposed.

If NASA had funded the X-33/VentureStar under the same procurement model as the Shuttle it would be flying today.

Perhaps. And likely just as big an economic disaster (and perhaps safety one as well) as the Shuttle.

We don’t like that form of procurement because historically, in terms of affordable access to space, it has repeatedly been proven not to work.

Anyway, I do need to write that essay. We’re not going to get energy independence from government crash programs (though prizes may be useful).

Roomba Hacking

7 Comments

We haven’t been using the Roomba for a while, because Patricia loves the new Dyson. But it excels at vacuuming under the bed, so we tried it for that today. It ran for about five minutes, and died.

I put it back on the charger, and it charged quickly. Too quickly, I fear. I think that the batteries have seen their last.

I was looking on line to see how much replacements are, and found a site that describes how to replace the Roomba batteries with standard sub-C NiMH batteries, with much more capacity than the factory original (four hours on a charge). I may give it a try.
