    Can it count towards CE credits I am required by state to pay someone for?

    I have no idea. You'd have to contact them about that.

    But...since the course is based out of the Netherlands, I doubt they are set up with any CE programs here in the USA.

Just some questions.


    I'm pretty sure that you're thinking of CO (carbon monoxide), not CO2 (carbon dioxide).

    A lot of people are concerned about CO2 as a greenhouse gas.

    Where it becomes more appealing is when you compare a pound of refrigerant to a pound of CO2.

    R404a has a gwp of 3922 meaning that one pound of R404a is equivalent to almost 2 tons of CO2 in terms of global warming.

    GWP is based on CO2 one pound of co2 has a rating of 1, so it's easy to equate the differenceses between HFC's and HCFC's, they are compared to CO2 for greenhouse effect ratings!

    So, anyone know how the "GWP" and "ODP" were designed and just how scientific these gauges are?

    Here's a hint; It's all a bunch of manufactured bullcrap, right along with "good/bad ozone" and "CO2" as being toxic.

    Yeah I guess chemistry is crazy eh?
    Ozone is ozone, it's the altitude which it resides in that makes it good or bad.

    Download NASA JPL's Earth now app and you can see just how scientific the hole in the ozone layer is.

    Wrong! Ozone is ozone....period. Ground level ozone is very important and cannot be decreased no matter how much environMENTALISTS claim it needs to be. That's the beauty of the way these users and posers have designed their methods of madness that are costing us billions of dollars every year.

    NASA is just another government agency looking for ways to bilk us out of our hard earned money through taxes, just like the EPA. At least NASA has been a little more honest recently, but still, all government agencies are now out for one main thing; OUR MONEY!

    GWP and ODP are both arbitrary scales. GWP is based on CO2=1; ODP based on CFC-11 =1
    Ozone is toxic and irritates our respiratory tract. It's not a pollutant that "ruins the environment" IMO.
    It's a problem in places like Los Angeles where the climate encourages photochemical smog and concentrated source of pollutants.
    O3 and NOx are both natural. They only become a problem when the level gets too high.

    Ozone is useful way up there in stratosphere, because it's a gaseous filter that is opaque to shortwave UV. Toxicity isn't a concern since we don't breath anything up that high.

    All accurate, other than it being a stretch to call ozone "toxic". At the levels that ozone is toxic, even Los Angelos hasn't hit that mark.

    Ozone is not smog, as the EPA claims it is. Ozone is found in smog because the man made components that make up smog produce ozone when UV light and heat breaks off an oxygen atom from the harmful pollutants, rendering those pollutants non-harmful. In other words, higher levels of ozone in smog is what keeps smog from being way more harmful than it is.

    Ozone is also produced when sunlight and heat break off oxygen atoms from naturally produced VOC's in rural areas where there are very little man made pollutants, such as Lancaster county, PA.

    Solution to pollution is dilution. VOCs, PMs and CO from a ton of cars in close proximity is an issue. That's why rural areas don't always have the same restrictions that apply to metro area. Inhaled ozone has same toxicity profile as nitrogen oxides.
    Ozone and NOx levels in LA may not be above OSHA TWA 8-hr level but that doesn't mean breathing in below that level at 24/7 is healthy. As you know some people are far more sensitive to air quality.

    Burning one candle in the house is fine... but burn hundreds at once and it'll be like running a car in the garage with the door closed.

    Ozone is extremely irritating. Cars, sites of unattended death dedecay, etc are routinely deodorized with ozone owing to its powerful oxidizing effect. It's produced when there's a corona discharge and a small amount is produced in laser printers. Some laser printers have a ozone filter to prevent ozone from entering the office space as its harmful.
