A Misapplication Of Rockets

Glenn (and Popular Mechanics) confuse the terms. As is pointed out in the article, rocket packs aren’t “jet” packs.

Remember the rules? If you want to cruise in the atmosphere, use an air breather. A rocket belt sounds cool, but it really makes no sense for this application. Rockets are for accelerating, and getting out of the atmosphere as soon as possible (or for traveling in space, if you’ve already done that). They’re not for tooling around near the ground, or for atmospheric transportation (rocket races being an exception, because it helps push the technology, and sounds cool). A true jet pack, though, would be actually cool, as opposed to merely sounding (and looking, when you see a pro do it at a show, for a minute or so) cool.

Is This Really A Younger Generation Thing?

I’m not in the cohort discussed in this article, but I’ll often go weeks without carrying any cash. I find the only time that I need it is on business trips when dining out with others, and have to split a bill. Even then, though, we often either have the waitperson split the bill on separate cards, or I’ll be the one to take the cash and put it on my mine (after which I have cash for the next time).

Maybe the difference between me and the people being discussed here is that I use credit, rather than debit cards. I can see how it would be tough to track your balance if you charged everything to your checking account.

More Options

Randall Parker has a list of consequences when the cost of individual gene sequencing comes down (as it inevitably will). I found this one interesting:

Discovery of genetic variations that contribute to appearances such as genes for eye and hair color, complexion, hair texture, facial shape, and other attributes that contribute to visual desirability.

Physical desirability is a two-way street. We are bred to appear desirable, but we’re also bred to view desirable people as desirable. I wonder if some people might not figure out how to rearrange their genes to change what is desirable to them? That’s probably a much tougher problem, though.

Save The Planet

…by not recycling:

…recycling is no way to reduce global warming. In fact, by increasing energy use, it worsens it.

[Update mid morning]

Someone asked in comments in this post if I made up the phrase “Green Man’s Burden,” and if it was the first usage. Well, it turns out that I wasn’t first (though I did come up with it independently). Here’s an instance of it at the Competitive Enterprise Institute back in 2000. And here’s an instance on Usenet from 1991. Great minds think alike, I guess.
