Technical Ignorami

And the sustainable development/energy folks wonder why they can’t get us to take them seriously.

Check out this bit of technological illiteracy in an FAQ on energy sources:

Why don’t we build a solar plant on the moon and beam the energy back to Earth?

We don’t do this for the same reason we don’t cover North Dakota with wind turbines to supply the whole country with electricity; transmission costs. Disregarding the insanely expensive cost of building a solar plant on the moon, transmitting this energy back would be technically impossible. In addition, with the rotation of the moon and the earth as they are, the transmission cables would quickly become terribly tangled.

But wait–if they use “transmission lines,” then it’s not technically impossible, just difficult. Of course, it would only occur to idiots like this to use transmission lines, and of course the question said nothing about transmission lines–it asked about beaming power.

“Beaming” electricity is not quite the same as beaming Scotty up to the Enterprise.

True. Unlike beaming Scotty, it’s actually been demonstrated, with 90% efficiency…

Electricity travels along transmission cables that are inefficient and very expensive: high voltage cables can cost thousands of dollars per mile. [42] If we could devise a way to efficiently “beam” electricity without transmission cables, we would be utilizing this technology first to connect earthbound power plants with various earthbound consumers.

Except for that nasty little line-of-sight problem…

They don’t seem to have any concept of using the right tool for the job. Of course, where you can, you use transmission lines, because they’re more efficient than beaming. But if you can’t, then beaming may be good enough.

Perhaps a better idea would be to build solar plants on the earth and then just keep the energy here.

Except that the sun goes out at night, and it’s diminished by clouds, and not all latitudes get decent sunlight, and…

The problem with terrestrial solar is the storage problem. It can’t provide reliable 24/7 power, and it will always be a marginal, decentralized source until we can come up with cost-effective ways to store large amounts of energy.

It is true that the sunlight on the moon’s surface can be more intense than on the earth’s surface, due to its lack of atmosphere, but this greater intensity does not justify the R&D effort that would be required to pursue extra-terrestrial capture of solar energy for use on earth.

No, it doesn’t. Of course “intensity” is not the reason that gathering power in space is potentially attractive, as the numbskull who wrote this would have learned from even a cursury glance at the abundant available literature.

The interesting features of space power are that it’s available continuously, there’s no weather to interfere with it, and you can get much higher effective power densities at the ground collector than with terrestrial solar.

Furthermore since most industrialized countries experience power losses of about 10% between the generating plant and the customer, which is only at most in the hundreds of kilometers, there is no way the energy would be still coursing through the transmission cables after the 384,400 kilometers it would have to travel from the moon to the earth. [43] [44]

Not just ignorance, but willful ignorance because, as I said, a quick google would have revealed how stupid a statement this is.

But these people live in their own little world, and when they hear about an idea, they don’t bother to actually research it, or give it any serious thought or analysis (though it’s not obvious in this case that whoever wrote this nonsense is even capable of it, either from an intelligence, or knowledge standpoint), because its politically incorrect. Unlimited power from space implies that we don’t have to live in their little “sustainable” renewable gulag, that we don’t have to give up our SUVs, that we don’t have to start splitting our own wood.

There are serious critiques to be made of space-based power (particularly from the Moon), and I’m on the fence as to whether or not it’s a viable future energy source, but this is simply pathetic.

The Plot Revealed

The Evil Jews (TM) are going to kill Arafat with poisonous death rays beamed into his brain, according to the loons.

I think they’d better tighten up their own foil hats–the poisonous death rays, emanating in the form of photons from their lunatic screeds into their brain via their ocular nerves, and phonons reverberating across the air of the mosques, have driven them so far around the bend, they can’t see the bend from there.

Bystanders

Mark Steyn discusses the culture of passivity and, as usual, nails it.

I have to say though, after reading this:

On September 11, 2001, the first individual to be named among the dead was the wife of the US Solicitor-General, Barbara Olson, whom I’d sat next to at dinner a couple of months earlier. On September 11, 2003, I woke to the news of the death of the Swedish foreign minister, Anna Lindh, whom I also sat next to a couple of months ago, at a conference.

As much as I enjoy his writing, I’d be a little nervous about having dinner or sitting next to him…

Plea to Capsicum Connoisseurs

I’ve had a bumper crop (in terms of patio farming) of chiles this summer. I’ve got a few Anaheims (that plant didn’t do that well, which is unfortunate, because I use it the most, and often sub it for bell peppers in recipes), quite a few jalapenos (some turning red), a bunch of serranos (about a third of which are now red), a good bush of little yellow but potent tabascos, and the biggest problem–several dozen large habaneros, fit for a sauce for Lucifer himself, and guaranteed to take the hair off any tongue that has the temerity to come within a quarter mile of them. I’m afraid that they’d have the effect of the Guatemalan insanity pepper from the Simpsons episode in which Homer had his vision quest. Muy, muy picante…

What should I do with them, both in terms of when to harvest, how to preserve or dry, and what kind of sauces, salsa, etc. to make with them? Also, how do I do all this, and live, or at least not burn off all of my precious guitar-playing digits?

Conventional Wisdom

Joe Pelton has an editorial over at space.com about space policy. It contains the usual justifications (we need to save ourselves from the asteroids, etc.), but while I agree that there are questions that have to be asked, I’m underwhelmed by his:

Why explore space and why send humans into space?

Why does NASA spend the money it does?

Why does NASA use the resources it has the way it does?

What is NASA?s role in terms of education, health care, energy and job creation?

Why is there not more international cooperation in space activities?

Should the U.S. government, at all levels, not realize it needs to do a better job telling us why space and space research, exploration and applications are key?

Why the focus on NASA? This needs to be framed much broader–what is the role of the government, and of the private sector?

And what’s the big deal about international cooperation? Why is this apparently a desirable goal, in and of itself? There’s no good reason for it to be. We should cooperate if it makes sense, not just for cooperation’s sake.

Non Sequitur

Gregg Easterbrook gives a little history of the Biosphere venture, and how Columbia University has finally ended its affiliation with it. But in the process, he makes a glib comment about the affordability of a Mars mission:

It seems certain that as the space shuttle debate continues, some prominent person will advocate the bold new adventure of a trip to Mars. When someone advocates that, this blog will demolish the idea in detail. Here’s a quick preview. Last week the Wall Street Journal ran a letter to the editor blithely asserting that colonization of Mars could be accomplished “easily and cheaply.” The Russian rocket manufacturer Energia recently estimated that the hardware for a stripped-down manned mission to Mars would weigh a minimum of 600 tons in low-earth orbit. At current space shuttle prices, it costs $15 billion to place 600 tons in low-earth orbit. That’s just the initial launch cost for a stripped-down high-risk flight with a couple of people–spaceship and supplies are extra.

Sorry, Gregg, this does not compute. Why would you take the word of Energia for the mass of a Mars mission, and then make the insane assumption that it would be delivered with a Shuttle (probably the most expensive launch system on the planet, and one to soon go out of business, one way or another)?

If you’re going to go with Russian quotes, use Russian launch prices. Of course, any rational person, contemplating fifteen billion dollars in launch costs, might consider spending that money instead on reducing launch costs…
