    I'm liking this a lot.
    Not meaning to throw cold water (all the time), the sentence above the one you quoted reads,

    The company’s technology is not aimed at capture — it would work with any existing carbon capture strategy. It’s goal is to be logistically simple and low cost — a drop-in complement acquired on-site and used on-site, at a relatively low cost.
    So, this company's technology is targeted at novel ways to use CO2, not to collect it. In my view, collecting CO2 so that it is useful for something is the big challenge.

    It pains me to link huffpost but a good example nonetheless of previous successes. Especially for Reagan lovers.

    Not open until end of 2016. Pretty high cost/KW. Not sure what their rate of production is. Seems like a proof in concept.

    It seems that sewage plants would be a great place to start if we could convert waste into fuel (for example). But sequestration won't become a reality for awhile according to this article.

    You can keep spitting out insults if you like. It doesn't advance the topic though.

    Eventually science gets it right. Confirmation bias doesn't help, but as I showed you it's not a terminal disease.
    Just to mix some actual information into the debate, Wikipedia lists various ways that commercial grade CO2 is produced (https://en.wikipedia.org/wiki/Carbon...and_production) and consumed (https://en.wikipedia.org/wiki/Carbon_dioxide#Uses).

    Here is a commercial CO2 production unit: http://www.ascoco2.com/en/products/c...uction-plants/

    Note that it produces CO2 by burning fuel in a controlled and closed system, and then isolating the CO2 through chemical absorption, release, and compression.

    The fuel is burned under carefully controlled conditions. After water/soda ash scrubbing, CO2 from the flue gas is
    absorbed into a monoethanolamine based solution which is subsequently heated by the combustion process to release
    the raw CO2 gas. The CO2 is then led to a vertical, two stage, dry running (oil free) compressor and on to the
    high pressure, potassium permanganate purifier. After thorough drying in an automatic twin tower molecular sieve
    drier, the CO2 receives final purification in an activated carbon filter prior to feeding into an R404a refrigeration loop
    in the liquefier. The pure, liquefied CO2 can then be fed to a bulk CO2 storage tank.

    This continuous process is efficient, reliable and safe. The CO2 meets international food-grade quality standards
    and is used daily by the world‘s top gas companies, soft drink and beer brands in over 100 countries.
    So, at the end of the day, combustion creates the CO2 (that part is easy), and a pretty fancy process collects and isolates the CO2 so that it now has practical commercial use (that part is difficult).

    No doubt, CO2 collection and isolation will start to proliferate where it may be economic to install the necessary hardware. These might start at utility power plants and chemical plants that burn clean fuel, just like other flue gas scrubbers started to become economic. A carbon tax will help immensely to promote adoption of industrial scale CO2 recovery.

    Collecting CO2 from the atmosphere (or from tailpipes) will come (if ever) long after easier and far more economic (i.e. large and concentrated) sources are exploited.

    You wanted to talk about solutions and now you don't. Fickle.

    Electric cars have been around since the 1880s. Carbon capture has been around millions of years but in the form of plants. To make it cost effective you would have to put money into it (subsidy). Are you voting for a carbon capture subsidy?

    Edit: I posted on this thread giving an example of a scientist who had a confirmation bias yet admitted to his incorrect assumption. Are you on drugs? I doubt there is anything a closed mind can teach another.

    Alright, don't let facts get in the way...

    From your article: "But from the mid-1950s, it rapidly fell out of favour, partly because of poor results and partly because of the introduction of the first wave of effective psychiatric drugs."

    Carbon capture is not ECONOMICALLY feasible - not even close. I stated that and you turned around and vomited a bunch of carbon capture fluff pieces from people looking for investment monies. I would love to believe it is possible in the near future but it is not, unless you want to destroy our economy. Do you?
    In a word, the challenge is entropy, indeed a VERY tough challenge.
