You can
a.) add it to fuel rods and burn it in a reactor
b.) break it down via neutron bombardment into shorter-life or stable isotopes. This is essentially a.
If you're talking about solid waste that's not recycleable, like the reactor housing itself, you're probably right. That's the basic idea behind Yucca Mtn.
With Hanaford, you're talking about millions of gallons of acidic radioactive sludge that's the byproduct of decades of fuel processing. This stuff can't be stored in a manner that'll be safe for more than a few decades without serious effort. IMHO the best option is to re-sort the stuff and process it for any useful isotopes; then, either solidify the rest for long term storage / disposal, or break it down into more stable or safer short-lived isotopes.
actually, this is wrong. As soon as you drop the throttle plate closed, the fuel flow is stopped as well. Descelerating engines have (had) a tendency to "pop" or backfire because the mixture goes lean while the system recovers. The lean mixture causes a missfire and that's how the excess fuel ends up in the exhaust manifold, where, it ignites.
the EGR adds inert gases (burned fuel) back into the intake stream. It does this at cruise and during deceleration to a.)decrease the cylinder temperature and b.)increase the "effective" compression ratio. This allows the use of a leaner mixture.
You're missing a point here. If you remove the nitrogen, you can increase the cylinder pressure and temperature without worrying about N20 production. Increasing either increases engine efficiency. Unfortunately, the energy expediture required to separate air would far outweigh the gains.
Nitrous is used in racing for one purpose only: generating GOBS of extra power. Using Nitrous in an engine is a balancing act. You have to actually reduce cylinder pressure (by backing off the timing) and temperature (by running a rich fuel mixture) to use it, without destroying your engine. It has the enormous benefit of allowing you to fill the cylinder with significantly more fuel (and the oxygen to match) yeilding more power. Think of it as supercharging on the cheap. If cylinder pressures get high enough in such an engine to actually produce N20, you're engine is going to self destruct.
Actually, you're wrong. While most later 4valve/cyl heads do use a hemi-like combustion chamber (part of the reason they generate more power), older 2valve/cyl heads almost all use a variation on a wedge shaped combustion chamber with the valves side by side (not inline with the flow) and the spark plug angled in from the side in a less than ideal orientation. Because it's a cheaper & easier design to manufacture .
crashworthness is another factor; as, it adds hundreds of pounds of metal to the structure
generally what you say is true. This is how cars are sold in Europe and Asia where many (but obviously not all) have somewhat smaller engines. The same car sold hear in the U.S. with a 2.0L would be sold in Europe with a 1.6L; maybe even a diesel engine option. They do this, of course, because Europeans are paying ~$5.00/gallon for fuel.
Companies that have tried this in the U.S. generally find the cars don't sell as well (since we generally pay under $2.00/gallon). People here would rather pay for a bigger more power engine than a smaller more fuel efficient one. The manufacturers are just feeding the perceived demands of the American consumers.
We should focus on stopping all the new coal fired power plants that are scheduled to come on line over the next 30 years from starting
Most of the coal plants being designed now achieve higher efficiency and lower emissions by gassifying the coal and burning the resulting gas(es) directly in the turbine. A second stage boiler is added to extract any remaining heat. They're much more efficient than the old plants; and, all the ash and other nasty crap is trapped in the gassification stage.
diesels get better mileage because the diesel thermodynamic cycle is more efficient than the otto thermodynamic cycle. Part of the reason for that is the higher (2.5X typically) compression ratio.
I think it's a cool commuter car; I'd build one myself if I had a garage...
However, it'd never meet current crash safety requirements under ntsb rules, as a car, on a public highway. No automotive manufacturer would ever consider it because of the liability issues.
just one note: diesels are switching from 2-stroke to 4-stroke to meet emissions requirements. Improvements in engine technology allow this with little or no loss in power over the predecessors.
because at 15 I was homeless. At 18 I was accepted to college because I graduated 13th in my class 3.9gpa anyway (still homeless). At 20 I had to leave college, go home to work, to save my sisters from my parents. at 25 got married. at 27 found out wife had lupus & rheumatoid At 27 I went back to college while working full time. at 30 I had cancer & had to drop out of school (again) also went bankrupt and lost all savings at 35, have no home of my own, still have no degree so work for slave wages at the only job(s) I can find (since most companies just toss my resume, given the lack of degree). Can't quit job & finish school because wife NEEDS my medical insurance. Can't start own company either for same reason.
life sucks and I'm very tired of it
Note to self, post this anonymously.... Screw it, don't care who knows.
It's well known that, when someone is asked to assess themselves, most people usually give themselves a higher rating than is reasonable or warranted. I tend to take the opposite tack and trash myself in a self assessment; but, that's my personal demon to live with. You can not ask a large group to rate themselves and not expect an above average result.
Having said that... This is/. for God's sake. What do you expect.
I wonder if it would be possible to set up a network of gigantic electromagnets and attempt to impede or even reverse the earths magnetic flip flop?
So, you're proposing we can change the flow of iron in a planetary core. Using electromagnets (because, they have magical powers, you know.) Hmmmm, this sound suspiciously like a really really bad movie I saw recently...
Linspire is Lindows. They changed the name to in an attempt to throw off the lawsuits brought on them by Microsoft.
Linspire has those limitations because it's designed for a linux newbie, maybe even someone who's never used a computer before. If you're an experienced linux user, you won't like Linspire.
Dell's not alone in this. HP has done it too. There's nothing to prevent a company like HP or Dell from throwing resources at some software development and creating a Linux spyware package. It just hasn't happened yet (that you know of).
That's Dell's story. Dell sells white-boxes to distributor channels and sells Dell branded machines to businesses with Free-DOS installed (they call it the No-OS option).
1.) Dell is bound by liscense agreements with Microsoft to ship consumer PC's with a copy of Windows installed. (notice I said consumer PC's)
2.) Dell does ship servers with linux pre-installed to businesses. So, there's no contractual requirement forcing Dell to ship a machine to a business with Windows.
3.) Dell will ship desktop machines to businesses with FreeDOS installed (they call it the no-OS option). This re-enforces the statement in 2.
4.) Questar is buying white-boxes with the no-OS option, and intalling Linspire itself. Questar then ships these to consumers. This is a work-around for case 1.
5.) Dell is testing the waters in Europe. Once they've got the bugs worked out, they'll start shipping machines, under another name, with Linux pre-installed, within the U.S.
There's nothing to prevent a mom and pop shop from buying white-boxes from Dell today and doing what Questar is doing, inside the U.S. Maybe this is what Dell wants. It's a win-win. They sell machines (albiet not Dell branded) and consumers get machines with Linux pre-installed.

Of course, I suppose a few people who also live in Virginia might be opposed to the idea...
is a distant echo of a toilet flush and the water swirling around the drain...

gasoline engines can run on alcohol with minor mods. same context as bio-diesel.

It's all chrome plated plastics now...
engine noise from the exhaust pipe
with the right resonator configuration, a 1.3L 4cyl can sound like an awfully big engine.
dangerously tinted windows
We're geeks, aren't we? I burn too easily
aggressive stance (too high to be stable)
Wrong Wrong Wrong... agressive == low and fast (with lots of stickers).
loose spinning reflectors on the wheels!!! Hate those.
jacked-up suspension, with angled drive train
those are the air bags. we can slam it to the ground if you like
V-Tec stickers :-)
don't forget the Type R 5.0 Magnum Hemi Edelbrock
violet underbody lighting
that's the 'friggin lazers warming up :)
wood trim
It's lighter than steel and comparable in weight to the plastic foam trim. Think of it as sequestering CO2.
audio system that everyone can hear
that's to drown out the blue-grass muzac coming from your station wagon.

Yes, and you can get the cheapest PC's with no operating system (ships with FreeDOS)
