an O2 cylinder is full at 2000 PSI a Nitrous cylindr is full at 850PSI, mixing the two in the cylinder is going to give a highly variable mixture; and there is no "perfectly safe, minimalist setup "; a sedation unit used in Dentistry is going to run you $2500.00 - $3,000.00 with scavenging unit and that doesn't count the wall mount manifold with the fail-safe valve that cuts off the nitrous flow when there is no O2 pressure. Your misinformation is just wishful thinking on the part of high-ons trying to convince themselves that huffing Nitrous isn't potentially deadly.
I can guess who you'd vote for out of Bush (an idiot) and Obama (not an idiot). Your presuming something that hasn't been clearly demonstrated yet. Lets wait and see when he actually does something that we wouldn't expect from Bush.
Not sure how your measuring 50:50 but most Dentists typically administer at 5L/Min O2 and 2L/Min N2O. occasionally kick it up to 4L/minO2:3L/minN2O for induction then back down to 5:2 for maintenance.
1/ Is this enough heat to melt the rubber on vehicle tires? no does your electric window deicer in your car's back windshield melt the tires? 2/ Can it burn the skin? see above 3/ What about chewing gum and other pieces of crap that will get onto the roads? see above
"this would epically fail in Amish country -- metal-shod horses are rough on asphalt, through plastic cratering, but would be absolute hell on glass."
Most Amish aren't cruel enough to their animals as to force them to work long distances on hard-surfaces with metal shoes, rubber soled shoes are much kinder.
That, and the fact that the Amish don't use electricity in the first place so it's kind of a moot issue.
The Amish do use electricity, they just like being self-sufficient more, self-generation allows electricity without being dependant on the outside world. Every Perish has different rules and most have one or two individuals that push the limits.
That's what's not clear is what the boiler is producing in saturated steam before it's superheated, I found that the car in the article is in fact superheated to 782F, where the stanley's boiler ran at 600PSI and gives the temperature as 488F, so the extra 150 degrees of superheat brings the system up to 638 F.
my Cyclopedia of Engineering Vol. II dated 1913 has a chapter on steam turbines and mentions their use in dreadnought class warships, thats hand stoked coal boilers feeding steam turbine engines.
Stanley steamers generate steam in drum shaped boilers ranging from 14" to 30" in diameter and from 14" to 18" in height. Similar to a battery the Stanley boiler stores steam energy for later use on demand. Unique in their design, no Stanley boiler has ever been documented to explode. The circular boiler walls are strengthened with three layers of exceptionally strong piano wire to provide sidewall strength unequalled in boiler designs for similar ratings. The use of between 500 and 1,000 fire tubes not only efficiently transfers heat to the water, they provide a structural strength to the boiler ends. Operated nominally at 600 PSIG, boilers were factory tested to twice operating pressure before being placed in a car. Once generated, steam is released from the boiler through a driver controlled throttling valve. The steam is routed to the engine after making a final pass through the burner fire to absorb 150-degrees or so of additional superheat energy. Stanley Motor Carriages technical specifications
Saturated steam tables 600PSI and gives the temperature as 488F, so the extra 150 degrees of superheat brings the system up to 638 F; the modern speedster is running 752 degrees F superheated for a difference of 16%. I don't think using modern materials would make much difference, the Stanley was far ahead of it's time. With rankin cycle engine the magic sauce is in the delta T so the boiler is most critical not the engine. The biggest gains are in the superheater, then next in condensers. A good condenser that can get the exhaust pressure down to 3 PSI absolute makes a big difference too.
1. glass absorbs IR, CO2 absorbs IR, 2. greenhouses get warm, the Earth gets warm 3. greenhouses get warmer irregardless of whether the glazing absorbs IR therefore AWG argument are false. That's what a lot of people think, using sloppy inaccurate terminology and you'll have to make the same arguments over and over
Besides, the greenhouse effect is basic science. Greenhouses work by the glass stopping convection cool not by absorbing infrared heat. You can make a greenhouse out of glass which absorbs IR and one out of salt which doesn't and both will maintain near identical temperatures, this is middle-school level science. Dumbing-down your arguments for the ignorant masses merely causes the astute amateurs to dig in their heels.
I didn't see anything there that we aren't doing here anyways. My state Michigan is committed to have 10% of our energy coming from renewable resources and we are making significant progress even with one of the highest unemployment rate s in the country. Very week I see at least one windmill pylon going down the highway. As far as insulation that's required by building codes, and Michigan is also an agriculture state, we grow lot's of corn and sugar beets E10 fuel has been used here for at least 30 years!
American businesses were able to severely cut acid-rain causing sulfur emissions, and CFC emissions, and still keep growing, but are too dumb to be able to severely cut CO2 emissions? Sorry you have such little faith in American ingenuity.
The acid rain is pretty much a red herring issue, acid rain is very local only affecting the US and Canada and the causality was painfully obvious. The remedies were largely effective, nobody even talks about acid rain anymore and the credits are pretty much worthless now. The AGW on the other hand doesn't have the obvious causality, add to it bad data, suspicious proxy data, crude computer models and the remediations feels like the non-productive punishing the productive it's no wonder there is skepticism.
The EPA can only affect American businesses. And of course the US cannot meaningfully influence other countries to clean up their act until it cleans up its own.
Which many view as even if we hurt ourselves to "save the world" others will just destroy it faster.
I bet if you installed Windows Server 2008 on your laptop the battery life would kinda suck to; Server OSes tend to expect they'll be running balls to the wall ready to spawn new processes by the hundreds, not conserving a few mAHrs of battery life.
Yeah that's like the people who say they have strong people skills, frequently they can't recognize they difference between building an agreement and bullying opposing points of view into submission.
Some movie characterful said the safest place to be hit with lightening in in the anus,but mooning Zeus seems to be asking for trouble if you ask me; I'm sure there is a goatse joke in there somewhere as well.
You do realize that there is a truck driver that knows so much about the nuclear weapons built in the 1940s and '50s that he has been invited to give presentations at Los Almos. Some people like menial labor because it give them the opportunity to think about things they are more passionate about.
Obviously you've never had a vampyric, somatic narcissistic woman sink her fangs into you. Bedroom skills have nothing to do with what makes them happy. what makes them happy is taking every social, psychological and financial resource you have for themselves, they feed off your pain.
Isaac Asimov: isn't the the guy that said "either everything we know about particle research is wrong or the sun has gone out, therefore the sun has gone out" many years ago when the solar neutrino flux was observed to be well below expected values because he didn't know about neutrinos flavor oscillation .
And according to GR, the length of your ruler is also different at the top of Mount Everest compared to at sea level!
Which is why I can't understand who LIGO really works, I understand the Michelson interferometer, I understand the Fabry-Perot interferometer, what I can't get my head around is the changing length of the arms. If the gravity wave wraps time-space, then should any length in that time-space be constant ( the ruler changes as much as the object being measured)? When space contracts, doesn't time expand so that C is constant?
This is what I don't understand - they're taking sequestered carbon out of seawater and burning it back into the atmosphere as jet fuel, at a huge additional energy cost during the conversion.
This is 'green'? Have I missed something...?
Actually you have , first it probably takes almost a gallon of oil to get a gallon of oil out of the ground, then you have to add more oil, about 5 gallons to refine 100 gallons to turn the crude oil into something usefull. Then you have to ship that a couple thousand miles to the fleet which takes more fuel for the cargo ship; so fuel get precious fast. Almost anything would be "greener".

"Balloon gas" frequently isn't pure, and welding gas will sometimes contain argon.

They put enough sulfur-oxides in the racing stuff that people will not huff it, only difference.

nope his escape rocket didn't have enough oomph to get out of the fiery debris field.

No we haven't but I've seen some pretty amazing designs from small low-budget outfits.
