Space Balls Invade Mars!

Posted in by Kenneth Newquist on Tue, 10/21/2008 - 8:08pm

No, I'm not talking about those Space Balls

NASA will be landing the truck-sized Mars Research Laboratory on Mars in Fall 2009. If the Swedes have their way, the gigantic rover will be accompanied by a number of ball-shaped probes that will roll around the larger probe. The idea is that the balls can go places the rover can't, and that their round shape will prevent them from getting stuck.

It all reminds me of the probes that used to orbit seaQuest DSV (yes, I used to watch seaQuest). Sure, we're talking sand instead of water, but it's the same basic idea, and very cool either way.

CNN: Space Elevator could take humans to orbit

Posted in by Kenneth Newquist on Wed, 10/08/2008 - 5:30am

One of the exceedingly cool things about living in the time we live in is this: some of the really hardcore science fiction ideas of the past 50 years are becoming technically possible. Now they may not be practical, but I find it amazing that we can seriously contemplate building something like a space elevator.

This article on CNN talks about a world-wide conference being held in Japan this fall to discuss the feasibility of such a project.  As the article states, the space elevator was first suggested by Arthur C. Clarke in his novel The Fountains of Paradise in 1979. It's shown up in other novesl since then; the most memorable one I can remember is Kim Stanley Robinson's martian space elevator in Red Mars (a technological feat made easier by the Red Planet's lower gravity; the elevator's fall from orbit during the Martian revolution is one of the book's most amazing scenes.

CNET: The Physics of Baseball

Posted in by Kenneth Newquist on Sun, 04/13/2008 - 7:54pm

I don't doubt that some people feel that knowing the physics of baseball removes some of the romance from the game. Me? I think it makes the game all the more fascinating. CNET's Daniel Terdiman writes about a presentation on the physics of baseball by Paul Doherty at San Francisco's Exploratorium. Doherty talks about how curveball's curve, why knuckleballs are so damn hard to hit, and where the sweet spot is on a baseball bat.

Reason: The Biofuel Brew Ha-Ha

Posted in by Kenneth Newquist on Thu, 04/10/2008 - 7:26pm

It was bad enough when the corn biofuel debacle drove up gas and food prices, but now the biofuel debacle is messing with my beer, as chronicled in this article on Reason.

Actually, I already knew this -- the my local brewery, Weyerbacher, had already explained how ethanol was driving up their costs by increasing demand for corn, leading to a shortage of less profitable hops.

CNN: Lean, Green Energy Machine

Posted in by Kenneth Newquist on Tue, 04/08/2008 - 8:58am

When I hear people lamenting the eventual end of the Age of Oil, and gnashing their teeth about where our power is going to come from, the science fiction geek in me has to laugh. The sun radiates enough power to keep us in electricity for billions of years; we just need to figure out the most efficient way to capture it. Which is why this story is such a good read; it discusses using fast-growing algae to produce oil, which then can be used as biofuel. While still experimental, it's already proving itself to be far more efficient then producing ethanol from corn, and even better, it could be use to sequester CO2 from factories, since the algae needs CO2 for photosythnesis.

This is the sort of innovation we need, not dead ends like corn-based ethanol that end up using more fuel then they produce, while simultaneously driving up food prices as more and more land is planted for corn rather than other staple crops.

Wired: Scientists Want Your MacBook for Earthquake Detection

Posted in by Kenneth Newquist on Mon, 04/07/2008 - 12:29pm

Earthquakes cause vibrations. Certain Mac and PC notebook computers come with vibration detectors used to shutdown their hard drives should the computers fall. So why not, asks a seismologist, use the accelerometers on the computers as a distributed network for detecting earthquakes?.

You can help out by visiting the Quake Catcher Network's home page. Right now it only works on Macs, but a version for HP laptops is coming soon.

Rolling Stone: Ethanol Scam

Posted in by Kenneth Newquist on Fri, 08/03/2007 - 7:43am

I'm glad to see that some of the more mainstream publications are coming to the realization that ethanol is a boondoggle that's going to end up costing us billions, both at the gas pump and at the dinner table, without making a significant impact on global warming emissions. The latest of these articles is by Jeff Goodell at Rolling Stone , and here's the point that I think everyone needs to understand:

CNN: Google Pushes 100-mpg Car

Posted in by Kenneth Newquist on Wed, 06/20/2007 - 7:31am

This is very cool. Google has awarded a million dollars in grants, and is offering $10 million more, to those supporting and developing plug-in hybrid cars that are not only more fuel efficient, but can plug into the grid and sell power back to it during peak hours. Granted, it's only a few million dollars, but it seems like Google's just getting its feet wet here -- hopefully we'll see more initiatives, and more private funds, from them in the future.

CNN: Planes with freaking LASER beams...

Posted in by Kenneth Newquist on Wed, 01/17/2007 - 7:30am

CNN reports that the first commercial jet with an onboard anti-missile laser system is now in operation. It's part of a pilot program to see how Northrop Grumman's Guardian anti-missile system behaves on a working commercial jetliner, and what impact it has on its maintenance and operational schedule.

The system works by firing an invisible laser beam at the guidance system of an on-rushing missile, disrupting it and causing the projectile to miss the plane. The goal is to prevent attacks by shoulder-launched missiles, but since officials say it could take 20 years to equip the commercial fleet with such system, you have to wonder if it's worth it. Won't some other, more modern threat to planes have emerged by then? Or will the missile technology be so cheap and widespread that we'll have terrorists regularly taking potshots at jetliners as they fly overhead?

Wired: Road Testing BMW's Hydrogen 7

Posted in by Kenneth Newquist on Wed, 11/15/2006 - 3:00am

Practical hydrogen powered vehicles are something that most geeks would love to see within our lifetimes ... and preferably much sooner. BMW's Hydrogen 7 series offers a glimpse of that future with a gas/hydrogen hybrid that puts a hydrogen fuel tank (actual liquid hydrogen, not fuel cells) and allows the drive to switch between gas and hydrogen at the bush of a button. Wired test drove one of the Hydrogen 7's in Germany and offers its insights into the prototype including the good (very low emissions that are mostly water vapor), the not-so-good (the eventual boiling off of the hydrogen over the course of 10-12 days) and the potentially nervewracking (refueling said hydrogen fuel tank).
