Researchers have combined gold nanoparticles (in light red) with copper nanoparticles (in light green) to form hybrid nanoparticles (dark red), which they turned into powder (foreground) to catalyze carbon dioxide reduction.

Copper -- the stuff of pennies... Actually, that would be Zinc.

When fashioned into an electrode and stimulated with voltage...How much voltage, for how long? IOW, will it cost more to supply the necessary voltage than the net value of the fuel produced?
Will it end up as inefficient as the other "green" technologies?

recycling carbon dioxide emissions in powerplants: Instead of being released into the atmosphere, carbon dioxide would be circulated through a copper catalyst and turned into methane which could then power the rest of the plant. I guess I'm missing the point. Thermodynamics requires MORE energy to convert CO2 into methane than can be produced by converting (combustion of) methane back into CO2 and H2O. The total mass of carbon remains constant. So how does this help?

Wait a minute - they burn methane which produces carbon dioxide which they convert back into methane which they burn which produces carbon dioxide which they convert back into methane.....

turned into methane which could then power the rest of the plant. When methane is burned the carbon turns back into CO2 so there is no net gain. Are they suggesting they've discovered a perpetual motion machine? Is there any point in doing this?

suck all the CO2 out of the air and then wonder why all the plants are ,ah, dead
To: knittnmom
This sounds really fishy to this old engineer, but I’m burdened with those old, crusty laws of thermodynamics that were formulated before the days of quantum physics and nanotechnology. Still, the prospect of oxidizing CH4 to form CO2 and H20 to release energy and then taking “relatively little energy” to convert CO2 to CH4 sounds more like a perpetual motion machine than an economically viable process.
To: LucianOfSamasota
I guess the point is the carbon never leaves the plant.?..........

The methane produced would not generate power for the grid, just the power to run the facilities at the plant..........

Sounds like another great money-wasting scheme to me. But it’s great for Professorette Chu, whose research is probably funded by Steven Chu (no relation?).
Meantime, they’re blocking the nuclear plants and shutting down the coal plants that would produce the needed electricity to do this.
Lights out! Time to freeze in the dark, while starving the plants.

More than likely, the cost of producing the catalyst will be higher than the energy from the hydrocarbons produced. No where in the article did they give hard numbers for the energy cost of making this catalyst. Also, there are ALWAYS problems with scaling up a lab process to a commercial operation. Things that work well on small scales sometimes have a tendency to get unstable when scaled up.

Then the amount of energy to recycle more and more carbon will eventual overwhelm the productive capacity of the plant, consuming all energy converted from combustion of new carbon based fuels. Very strange.

EPA will throw a tissy fit and will hold their breath and faint because they won't be able to fine them for CO2 emissions.
To: LucianOfSamasota
I guess I'm missing the point. Actually, you got the point. The author is counting on the 99% that read the article and never understand that point.
They hope you will flood the phone banks of your congress representative to fund this important research.
No different than the chasing of hydrogen fuel for the exact same reason.

When methane is burned the carbon turns back into CO2 so there is no net gain. Worse, there is some loss at each step.
