Gallery: CONVERTING CO2 TO ENERGY: Environmental 2-For-1


Here’s a promising idea that could help alleviate two environmental problems at the same time: potentially decreasing carbon emissions while also generating renewable energy for transportation and electricity. Clifford Kubiak and Aaron Sathrum from the University of San Diego have devised a way to use solar energy to obtain both fuel and electricity from CO2, and have a working prototype to prove it. Talk about killing two birds with one stone! (metaphorically of course).

    I have a prototype… Home build with commercial available materials… it turns co2 into co and i use it on daily base…
    using it for cooking, driving the motorbike, water pumping, charging the home battery set, generating electricity at work…

    the idea works but obviously the by product has common flaws shared with other ideas that are already out there and are used on a day to day basis, lpg; where i think this has the attraction is that it also leaves room that with some vague testing out in more so unpopulated areas there could be a compromise between wastage and already provided atmosoheric conditions already provided i.e. tokyo, new york, london, all of these have the co2 that could be better used but still a “cancelling out affect” would have to be put in place before it would be able to be released to the vast machine that is “world”

    How about nucleosynthesis (fusion) of carbon & oxygen into neon, using resulting energy to power the planet (same as what massive stars do), and neons for fancy displays.

    it’s has review many sites like gas for free,run your car on water etc.

    Finally, someone is trying it. I thought about this a while back after the global warming issue became a media attention getter. It seems like it should be quite possible. Plants do it, we have to be able to.

    Dear Sir/Madam,

    There are alot of computers and mobile phones being wasted, can the glass or plastic be
    recyled and combined with other alternative & additives to create solar panels ?

    I am pushing as hard as I can in the “school and multi -res” architectural practice I am in, to
    make electrical engineers and school boards accept mass scale photvoltaics, but there
    are so many techinical hurdles, and issues to changes of employment to people working
    in the electricity industry. Not only are the creation of more jobs an issue, but also the fact
    that for a $6 M multi -purpose builing , we can only supply about 10-15% of the power
    required with photo-voltaics, what can be done to ECONOMICALLY to increase this

    Currently one idea is not to use batteries, and pump the electricity straight back into the grid,
    as batteries are expensive, large and don’t have long lives ?

    There must be a by-product, or waste material that these things can be made out of.

    And just a general issue on wind power, I think people would like to a greater variety of
    turbine shapes if these are ever to be used on a mass scale.

    The other thing I am pushing for is a continuously, updatable internet list for the building industry, that
    contains embodied energy quotas of common proprietry products.

    And finally, another thing I am pushing for is standard green specifications for the building industry,
    particulary in architecture , but obviously this should apply to mech, elec, hydraulics, civil and structural
    consultants as well.

    I would very much appreciate to know of any econimically applicable advancements that have been
    made in your country that have general industry acceptance?
