Correction: Most diesel vehicles will run fine on B20, but B100 (pure) will damage rubber hoses and gaskets. Cars with those (like mine) will need upgrades to accomodate B100.
Ethanol can be made from feed grain waste (when grains are raised for vitamins/minerals and the starch is discarded), and there's a net gain of ~16000 btu according to DOAg..
The theory is that electrical producers, being centrally located (and regulated) and large, can reduce the amount of pollution per kilowatt by improved processes and scale. There is some research on this and IIRC the conclusion is that there is a small net reduction in greenhouse gases, but definitely look it up.
As far as practicality goes, I still feel biodiesel's a good alternative, especially for larger vehicles and power generation.
All I can say is, I put my $$$ where my mouth is.. No biodiesel-touting 15mpg-SUV-driving hypocrite me;)
Hi, Hybrids really don't count IMHO as 'alternative fuel' vehicles, since they use two fuels that are exceedingly ordinary: gasoline and electricity. They should qualify for partial EV credit, and they're great for reducing fuel consumption, but without E85 they just aren't 'alternative fuel'.
I would recommend a late-model Volkswagen diesel and biodiesel as a true 'alternative fuel' vehicle. Diesels are more efficient, create less CO2 and other greenhouse gases, and last FOREVER. I just recently purchased a Mercedes diesel with 362000 miles on it, and I expect to get at least another 130000 miles on it with proper care and feeding. My car can't take 100% biodiesel without some fuel-line upgrades (bio eats rubber away since it's more oxygenated than petro) but any diesel since 1994 can take 100%. Another option, particularly in colder climes or with older cars, is B20, which is 20%bio/80%petro. Biodiesel doesn't contain sulfur, and is naturally oxygenated enough to prevent smelly particulate exhaust. In fact, tailpipe exhaust smells like french fries;) Biodiesel is actually technically non-toxic and very hard to burn, and IIRC can be drop-shipped anywhere, so I _THINK_ you could even have it delivered to your house in large drums.. It's expensive (~$3/gal) but it may be worth it to you if you want to contribute to (a)saving the ozone layer and/or (b)keeping US$ out of the hands of despotic Arab states (and their terrorist pawns)..
Couple interesting Wired links on biodiesel: here and here
Even non-biodiesel is a better global environmental choice than gasoline/petrol since it's less intensive to refine. Diesel creates more NOx, large-particulate exhaust and sulfur (which lead to smog and acid rain), but the balance of impact is in its favor overall due to the efficiency of diesel engines. Also, if we could press for low-sulfur diesel, NOx could be handled with catalytic converters.
Oh, did I mention that biodiesel can be made from any biological substance that contains triglycerides? Hempseed, soybean, even used cooking fats can be 'cracked' into biodiesel, leaving glycerin. What to do with the glycerin though, that's the main Q...
Hi,
Maybe I missed it, but is there a way to unsubscribe and yank all my old postings? If/. is going to regressively charge people more for contributing to the community more (as was stated in the article) I would rather not be part of that community. In addition, I'd also want, if I unsubscribe, to yank my prior comments as well. It should be a relatively simple SQL op.
I have a new Ti, and being the non-ignorant-fuck that I am, I also bought a USB 'Mouse in a box optical pro' from J&R computer world (support downtown NYC!!!) for $29. Both work great together.
Also, Mobile Radeon is quite nice for Aliens vs. Predator for OS X, and GNUChess beats my ass every time (yes, I suck at chess)..

Give it another week and it will probably be alot faster, better and more feature complete than that pile of crap that we refer to as netfilter.
That's funny, I've got a netfilter box hosting 4 IPSec tunnels as well as firewall duties for a 2mbps link, 256MB RAM on a Duron 750. Guess what my load is?
0.00 0.00 0.00
I have never seen it peak above 3% total utilization, even when maxing out data transfers on the 3DES/MD5 links.
Even if we bump our pipe to 10mbps, I doubt I'll have much to worry about.
btw, I've run about 500-600 simultaneous tracked connections (wc -l/proc/net/ip_conntrack) without even breaking a sweat. I could not possibly have bought a cheaper AMD system than I did (the box is assembled from parts and configured to boot off of mirrored 4.3GB HDDs), and it is STILL overpowered.
Check this out: it (or larger versions) was used to lift radio aerials during WWII. I had one about 8 years ago but I broke its balsa spars. I'll probably buy a new one and keep an eye out for fiberglass or carbon fiber spars;)
Still, I guess uptime on a sunday doesn't matter.. my own piddly box was down for a couple of weeks while I waited for a shitty enough day to waste on a sys rebuild..
The poor thing. It ran on 2x400MHz Celerons clock'd to 533, 256MB RAM on an Abit BP6. The RAM seems fine and the HDDs had no issues (I used the opportunity to drop my new copy of Mandrake PowerPack 8.0 and do everything right as Reiser from starters), I built the new system on a spare HDD and nuked the old partitions for MP3 space. Everything seems pretty hunky dory, though there are a few little bits that need reworkign and I need to rebuild my NFS/Appletalk shares..
ObGeek: Right now I'm posting to/., listening to 'Flood' in iTunes (on the cube that received my old server's PC100 DIMMs today.. 768MB!), while MandrakeUpdate is downloading the 8.0 updates in (WAIT FOR IT..........) XDarwin over SSH.

So far, I've been pretty lucky. I pretty much gotz my sysadmin/netadmin sk33lz in many flavors, and I don't drool or smell much. My current gig is a blast. I actually took a big NOC provider to school on VPNs recently, though that isn't really saying much:). Still, if everything went totally pear shaped I woudln't have too much trouble relocating up north and finishing my degree, playing Shadowrun, and otherwise geeking out until broadband actually rolls out;)

OK - here's my jobs list, in chronological order: paper boy (afternoon), paper boy (morning), HS projectionist (carbon arcs!), HS radio announcer and disc-jockey, summer field-hand, commercial announcer, materials handling office-manager / salesman / driver, coffee shop short-order cook, data-processing operator (tape-ape), DP night manager, H200 assembly and COBOL programmer, DEC TOPS-10 computer operator, DOS/VS computer operator, DP supervisor, COBOL Programmer trainee (twice, let's not get into that), network install manager, network support manager and programmer, OS/VS1 systems programmer, MVS systems programmer (three different companies), Big-8 IT senior consultant, Big-5 IT manager, IT consultant for a small private firm, and now an IT management consultant for a large multi-national firm).
Hehe, check it:
product tester for CTW Apple ][ computer games, age 9
paper boy (morning 7 days/wk), age 10-12
computer tutor for public library (volunteer), age 10-13
computer tutor for hire (consultant), age 11-current
computer repair guy, age 11-current:)
dishwasher, chicken rack cleaner at KFC, age 13-15 (my folks forged my papers to be 16+ so I could work with heavy machinery and earn more $$$.. Helps being 5'10" at age 13..)
cashier, cart pushing guy at supermarket, age 15-16
token guy at amusement park, concession lacky, age 16-18
car valet, age 17
skeet trap loader, age 17
dockboy, age 20
campus computer consultant (pc/mac/sunos/vax), age 19-21
And that doesn't even count my more boring (yet more lucrative) "career" as a sys/netadmin (have ssh client, will travel).. Hell, I'm still looking forward to 30..
I _like_ that the RC5/OGR code is optimized for each CPU instruction set. It means a few things:
my CPU is being used most efficiently/performantly, which satisfies my deepseated urge for efficency.
common algorithms (though implemented optimized per architecture) mean I can get apples/apples benchmarking for this particular problem domain
Efficient/optimized code generates more work per watt of electricity. Combining this with a form of throttling would help with energy conservation while still getting good results.
SETI does not optimize per platform, thus I will not use it. I can't stand to think that some of my available CPU is being simply wasted. I run AMD CPUs at work: I want 3DNow optimization on those clients. I have a G4 Cube in my bedroom: I want AltiVec optimization on that. Bovine does both IIRC, SETI does neither.
It's the same to me as the idea that when I buy an Intel product for, say, $200, that a dollar or two might go to those dopey Blue Men. That's why (among many reasons) I don't buy Intel products.

So, then the question is whether you would rather have 1 gallon worht of diesel emissions or 1.6 gallaons worth of unleaded emission?
:/
If you care about the local environment, go with the Gas: it produces less NOx and soot, which contribute to local smog.
If you care about the global environment, go with the Diesel: it produces less CO2 and other greenhouse gases.
Oh well..

Still, E85 can't be used in most auto engines: it's too corrosive. Cars that can use E85 typically state it in the owner's manual or somewhere...
Hi,
US Diesels can't have euro catalytic converters: our diesel's got too much sulfur in it.
Still, whenever we can get reduced-sulfur requirements into law (perhaps CA can lead the way in this??)..
