You still need the colder coil temperature to remove moisture. To maintain a maximum comfortable 50% RH at 75degF, you need a coil with a max water temperature of 62degF. Usually air comes off the cooling coil at 55degF and saturated [100%RH] so when it mixes with the air in the room, the resulting RH is about 30%. The moisture removal is arguably more important from a comfort standpoint.
Ethylene and propylene glycol reduce the efficiency compared to a 100% water heat transfer fluid. The viscosity of the solution is raised [harder to pump] and the specific heat is lowered [heat capacity per volume]. A 50% EG & water solution system capacity has to be oversized by about 20% to have the same performance characteristics as 100% water and the pumps have to be increased to overcome the increased viscosity. In order to increase the delta T to reduce flow, you have to have a source and sink with a great differential temperature.
I am an HVAC engineer and we do some LEED buildings as well as normal commercial work. I am relatively familiar with these systems and the main problem with ground source heat pumps are that the wells are very expensive to dig. For a large residential system, say 5-ton, the cost to dig the wells is somewhere around $20,000. If you put that in the upfront cost of a new house, maybe okay, but not too many homeowners are going to shell out $30,000 for a new furnace and a/c.
Also, the problem with heat pumps is capacity. You can use them with great effectiveness to heat in milder winter climates like the South, Florida is a good example, but if you tried one in say New York or Chicago [where I am], you will be running the supplemental electric or nat gas heat throughout most of the winter.
Same experience here. I think I've been using Gentoo/FreeBSD/Slackware for too many years. The no-text configuration seems to get in my way more than it helps. The funny thing is, when I went to there forums and asked why a Samba update was overwriting my config file I had hand editted, the mods there told I wasn't supposed to do that, or something to that affect. When I replied why not, they said I must of been some elitist Gentoo user [which I am, but that is besides the point]. It is still Linux, I should be able to get under the hood if need be.
I have a Honeywell Vision Pro 8000, I am an HVAC engineer and my Honeywell rep gave it to me. They are a little more expensive than your average programmable, about $120-$140 but really has some nice features. Google shopping link.
Every degree on your thermostat will save you about 3%. If you don't have a 7-day programmable thermostat, get one with 4 states, wake, leave, return and sleep. Increase the sleeping and leave temps to 85degF and then set to 78degF for the other periods. They are less than $100 and would pay for itself in a few months.
Depending on the orientation (North, etc) of the windows, replacing inefficient single panes with double panes that have some reflective properties that can lower the solar gain significantly. With the economy in shambles, you can get construction work done at a great discount. Depending on the number of windows you need done, you can get them for about $300-$600 a window.
I guess to add to my point, corn-based ethanol doesn't make sense, it is only being produced because of the subsidies. Switchgrass yields something on the order of 10x's more ethanol per acre but farmers don't get the huge subsidies to grow it. I have also seen some arguments that other crops were being abandoned to grow corn for ethanol because of the subsidies thus reducing the supply of other crops and increasing prices. Its not the governments job to set prices. There should be no subsidies, the agriculture business in this country is profitable without subsidies, why should taxpayer money go into the pockets of "big farm"? It ain't ma & pa tilling the fields anymore you know.
Depends on the wine and the grapes involved. You can over age wine, you will notice it loses much of its flavor. The same in respect to under aged wine, where you get high tannins and little fruit, over aging will usually result in a mess of indistinguishable subtle fruit flavors. Your heartier "big" reds like syrah, cabs and zins can age for decades [if they are of good quality, say $50 a bottle or better] but most are at their best drinkability within 5-8 years of the vintage date. As far as whites are concerned, unless you have a d'Yquem, drink within 5 years of the vintage.
I am [was] a volunteer security expert on CastleCops. I helped hundreds of people, but the task was very daunting. Back in the hayday for malware, there were literally hundreds of new posts everyday with problems that would take more than a canned response and a hijackthis log. There was only a handful of us and to be honest, I am surprised that it lasted as long as it did. I know I would get burned out and disappear for a few months then pop back in and try to help a couple people.
The last time I was in traffic court, the Judge proceeded the cases with stating that traffic tickets are not a criminal offense and you do not have the privilege of being innocent until proven guilty. I believe they fall under the umbrella of a civil offense in which the burden of proof of innocence falls on you the defendant. Of course, IANAL.
Windows only updates Windows programs, the updating systems in every linux distro I have used, quite a few, update everything installed. There is nothing in Windows to rival that. I understand that it is really impossible to implement especially due to the proprietary nature of most Windows software, but to say that it rivals any Linux distro's package management system is disingenuous.
I just spent 5 minutes trying to read your sig and still haven't done so successfully. I guess my boss is right, those lunch beers are affecting my productivity. Damn.
Basically yes and no. The world economy as it is today is highly dependent on the US consumer. Not knowing where you are from, but the European banks which were in a lagging housing boom following the US could be hit with similar declining real estate prices that are at the heart of the mess in the US.
Please note that I am not an economist but do follow the economy closely as a personal investor.
Actually the parent is wrong. The USD is gaining strength because the rest of the world is also in a recession. US Treasuries are the current preferred safe haven, its bad here but worse every where else. When other currencies are sold and US treasuries bought, the yield dives and the relative value increases. We are in rapid deflation, look at the prices of everything, they are down down down. The Fed printing money will have an inflationary affect but it ain't happening yet, the key is that they raise the interest rates and fast once this economic cycle is over to help curb inflation.
I am an HVAC engineer and I have had $30,000 condensing units destroyed on construction projects for $200 worth of copper. I've seen LIVE power feeds ripped off of buildings. Something needs to get done. Unfortunately as the old saying goes, people are assholes.
The $75/hour number is not incorrect. I never claimed that the workers were getting a salary of 75 per but that labor costs them 75 per, which it does. The article also backs up the $60k number. Is unskilled labor really worth that much to you? Seems unreasonable that an uneducated unskilled laborer should earn more than the average undergrad out of school.
Whether you care to admit it or not the union members don't make really anything more than what the non-union employees do for other companies in the US. The cost of labor is pretty much dead even over all.
Site one source that backs up your completely false claims. Every piece of hard information I can find puts the labor costs at GM around $75/hour and at Toyota $48/hour. The total cost difference per vehicle is right around $2,500 for labor and benefits between GM and Toyota. Assembly line monkeys without a high school diploma can get a $60,000 a year job plus benefits at a big 3 plant because of strongarmed union deals. That is fact.

Actually the use of 30% of the US's corn for ethanol because of misguided subsidies is one of the major causes of the massive hike in prices.

64-bit flash did fix those issues. You can download the alpha version here. I've been running it on Gentoo for a few weeks without issues.
