Here’s Richard Garriott on a recent Austin ZEROG flight

Fellow Austinite Richard Garriott talks more in the December issue of PC Gamer about his upcoming trip to space:

I grew up with an astronaut father, and space has been my pinnacle interest since I was young…. the probability of me going [to space] the same way my dad did was zero….

Since earning my earliest profits in the games industry, I have been investing in privatizing space….

Here’s how he enabled Dennis Tito to get into space with his investment in Space Adventures.

I am also involved in Zero G, which has given me a taste of what I might experience in space. Zero G uses a modified Boeing 727 to take people on parabolic flights into microgravity. Anyone can book these flights and I tell you, it will change your life. People get giddy on these flights; they experience true happiness and living in the moment. I enjoy these flights so much that I recently chartered four of them to help promote the release of my space epic MMPORG Tabula Rasa. And my experience on them solidified my desire to get private citizens into space as well–even those without bazillions of dollars.

… I am lucky enough to be able to go into space myself through our work with the Russian Government! Earlier this month, we announced that I will be going into space as the seventh private space explorer, and the first second-generation astronaut, next year. I can’t tell you how excited I am about this. But I’m still my father’s son[;] I will be part of a team conducting experiments and bringing back new knowledge and data concentrating in four areas: commercial, educational, environmental, and artistic. This isn’t just a joy ride for me; it’s something I need to do.

Amen on the ZEROG flights.

This technology seems to be moving along pretty well, and it’s one of the revolutions that will constitute a major solution to our energy problems.

This approach allowed the engineers at Standard Oil to build a multifarad device. At the time, even large capacitors had nowhere near a farad of capacitance. Today, ultracapacitors can store 5 percent as much energy as a modern lithium-ion battery. Ultracapacitors with a capacitance of up to 5000 farads measure about 5 centimeters by 5 cm by 15 cm, which is an amazingly high capacitance relative to its volume. The D-cell battery is also significantly heavier than the equivalently sized capacitor, which weighs about 60 grams.

I’ve probably told this story before about innumeracy, even of physics students, and the inability of some to think through a problem. When I was teaching an E&M lab in college, we were doing experiments with capacitors, and someone came up and said, “The lab instructions say to use a microfarad capacitor, but this one says MFARAD instead of (greek letter mu–the symbol for micro)FARAD. I assume it means megafarad. Don’t we have smaller ones?

I explained to him that the largest capacitor I’d ever seen (this was in the late seventies) was a quarter farad, and it took a truck to deliver it. Did he really think that he was holding something in his hand with four million times that capacity?

The article is also a good tutorial on capacitors in general, for those unfamiliar with how they work. The way that I like to think about this is that the positive charge accumulates on one plate, and the negative on the opposite one. They are held in place by their mutual attraction (being opposite charges), but cannot combine because of the insulation gap represented by the dielectric. The more accumulated charge, the higher the attraction (and field force) and accompanying voltage and potential energy. When the plates are allowed to connect to each other through an external circuit, the charges flow toward each other and create current (and power). The breakdown voltage is the voltage at which the gap can no longer restrain the attraction between the two groups of charge, and they jump across it to meet their destiny. This is to be avoided.

Sorry, link was slightly mangled (though usable) before. Fixed now.

Buy a cell phone jammer if you want to project 30-foot cones of silenced phones. Or if you don’t want to be arrested for using a jammer, build yourself a Faraday cage: no signal and no interference.

And here’s a discussion of another kind of blocked call out.

I’ll also be doing light posting. I’m having dinner and a ZEROG flight with Buzz Aldrin. There still appears to be some availability. If you can get to Vegas by 6:30 tonight, you can make the dinner and the ride prep starts tomorrow at one. The price is $8,900; it’s more than the regular price of $3,500, but less than $144k for a flight with Stephen Hawking. At $3500 for 25 seconds * 12 parabolas at 0g is $700/minute. That’s about a quarter the price per minute of a week in 0g on the International Space Station.

Here they are. I’d read most of them before, but it’s nice to have them all in one place. They’re missing Vannevar Bush’s quote about ICBMs.

Intercontinental guided missiles, Bush contends, need not be feared at all

Joel Garreau has an interesting WaPo piece on Aubrey de Grey.

Well, according to this article, we’re past it. I don’t buy it, though. It says nothing about shale or tar sands, which are going to come on line in quantities that will make current prices unsustainable. Another encouraging thing is that solar may become competitive within a decade. As the Guardian article points out, we are in an energy transition period, but it’s nowhere near as apocalyptic as it makes it out to be.

Glenn is kvetching about having to buy both types of HD players:

The prices have dropped enough that I might be able to buy this high-rated HD-DVD player and this Sony Blu-Ray player and not spend much, if any, more. On the other hand, the notion of having to buy two just bugs me somehow.

My preference, actually, is to buy two things if I have the room, and I can afford them. Bundling functions in a single unit might seem convenient and cost saving, but the problem with it is that if one component fails, you still have to either replace the entire thing, or at least replace the functionality of the part that failed. The old example would be a combination microwave/range. The microwave dies, and you not only have to go replace it, but you can’t find a stock replacement for it that will fit the range, so you have a permanently dead microwave in your kitchen, and have to take up space with the new one on or under the counter. Unless you go out and replace the entire stove, even though the range and conventional oven are just fine.

A more recent, and mundane example is these television/DVD combos. If the TV dies, it’s become a boat anchor, unless there’s a way to get the DVD output from it to bypass the TV. Plus, some of them (amazingly) are HDTVs, with standard DVDs (hopefully, they at least do up conversion). So you get instant obsolescence, built in! My (two-channel, thank you) stereo system still uses a separate pre-amp and power amp.

A risk analyst (like yours truly in his day job) would say that by increasing the complexity you’re increasing the probability of failure (can anyone say Space Shuttle? Apparently it really bugged NASA to have to buy both a launch vehicle and an orbital laboratory…)

But I suspect that bundling is the wave of the future, particularly as electronics continues to become less and less expensive (as living space becomes more so).
