I heard about that car some time ago. Part of its problem was they used it to power the transmission directly, so the turbine had to spool up/down constantly. That's a real turbine-killer.
What makes the hybrid situation different is that you could generate power by running the turbine at its optimum speed all the time, as opposed to accelerating/decelerating constantly.
How about a GPS-enabled shock collar? Or maybe a GPS- and flux gate magnetometer-enabled ear shocker that'll not only know when they've strayed out of bounds but will know which ear to zap to get them pointed in the right direction!
The idea behind plug-in hybrids is to make the electric motor the big engine and have a small gasoline motor who's only job is to charge the batteries when they get low.
I've always wondered if having a regular gasoline engine to turn the generator is as efficient as a small turbine. Supposedly turbines are most efficient at constant speed/load, which the generator would be. Anybody have any hard numbers?
In wine, however, expensive does not necessarily equate to a quality product. There are _very_ few people that are comfortable enough to admit that they like a less expensive wine. The parent is absolutely correct in that 'wine snobbery' is quite rampant. My wife's favorite wine is a Adolph Mueller Rheinhessen Niersteiner Gutes Domtal Spatlese. It's about $10/bottle. She absolutely adores it much to the chagrin of the chardonnay and merlot snobs at the wine store.
I sometimes get 'vapor locked' while zipping along in my sandrail. I guess the wind blows up under the windshield and across my nostrils just so and makes it very hard to inhale. Turning my head slightly breaks the seal, so to speak, and makes it easier to breathe.
Agreed. When I told a petrol station worker that the lowest grade of gasoline we have in the US is 87 octane his reply was "Why, that's paraffin!" IIRC, the petrol in Scotland was 95 octane, according to their measurement method. I don't remember if they use (RON+MON)/2.
Good point. The microphones in question will be banned from the new 700 MHz safety band after the DTV cut-over, and will be useless within used DTV channels. Paradoxically, the FCC docs clearly outline testing against part 74 wireless mics. How those two statements fit together I cannot fathom.
You know, it really irritates me when a writer feels that they must 'cross-reference' other works, classical or not, that are outside their work's milieu. Bandersnatchi, Clive Cussler appearing in Dirk Pitt novels, etc.
I give Frank Herbert a pass for the crossover words used in "Dune" because those characters were supposed to be a distant offshoot of humanity, and they brought with them...elements of most ancient religions.
The rest of you authors, however, need to CUT IT OUT! It cheapens your work considerably when you go for the low-brow association with other works.
My answer: ZigBee! They're mesh topology, so you don't have to have line-of-sight to the coordinator. They have interoperability as part of the ZigBee spec by using defined profiles.
These specific devices are essentially rs-232 devices with some A/D and digital I/O lines. The end device incarnation can sleep most of the time and awake to take samples. You can run a 'sleepy' endpoint on batteries for 1 yr+. With a decent antenna, you can get pretty far on 1-2mW, and if you've got power available, they sell 100mW versions. I'm setting up monitoring using these beasts, and hope to use the same protocol for my home entertainment system.
8-Tracks never caught on in Australia so please refrain from telling me about how they were much better than CC.
I don't remember if they actually sounded better, but I know that the very loud 'kerchunk' in the middle of a song on a poorly laid-out 8-track was extremely annoying!
On the technical side, the tape may have moved at 3.75 inches/sec (2x cassette tape speed), but the movement of the heads to advance tracks almost guaranteed that they'd be either skewed or off center, making for lousy sound.
Very well put. That doesn't preclude switching in a narrow analog filter (a SAW or other IF filter) when you want the narrow band performance. If the filter has sufficient rejection, you could even use subsampling.
Well, I could imagine that it's easier to make a wideband-capable radio transmit a narrowband signal than the other way around. Personally I'd rather have a general-purpose device _capable_ of transmitting and receiving ATSC video, say, and also transmitting SSB or PSK31. Clever DSP can make a wideband radio into (effectively) a narrowband one, but not vice versa.
There's also UWB and spread spectrum to consider, as well as the ability for a smart radio to receive a whole band simultaneously, and present the parts you're interested in. For instance, if my radio was able to listen in on the entire 88-108 MHz FM band, I could have it decode all the digital traffic info for me, as well as switch to the station playing "Afternoon Delight" by the Starland Vocal Band.
... paying... $250/month for 72 months is better than paying $350/month for 48 months for the same car.
It depends on how you look at it. From a strictly dollars and cents perspective, you're right. If I'm uncertain about the economy or my job prospects, I'd gladly pay $1200 over 6 years for 'insurance' against having an extra $100/month payment if I lose my job.
That's the same reason I choose a longer mortgage for my house to obtain a low required monthly payment, but regularly pay ahead on the principal to reduce my total expenditure. If I lose my job or are disabled, I can fall back on the lower minimum payment. I realize that simple vs compound interest loans are different, but the principle is the same.

I swear the recent e. coli outbreaks from tainted lettuce and spinach are from the distinct lack of toilet paper in the fields.

This makes the Red October's propulsion system silent _and_ deadly.
That efficiency figure was "... measured under [the] concentrated light of 326 suns." Let me know when they've installed the other 325 suns.

Funny! My nick is a rip of Herbert's, but I wouldn't use it in a novel. It was either Muad'Dave or Muad'Dipshit, both equally apropos.

I don't like cats. Let me know when they find the naphthalene dogion in the light.
