And why is the end production not carbon but carbon monoxide? Can I ask your some questions: What exactly is the iron oxide? And why is the end production not carbon but carbon monoxide?

Dear all,

you are doing good job.

False Statement. The overall cycle of this system would not produce or retract pollutants or green house gasses. This is a neutral cycle. @Bensch Getting power from the sun is one thing, storing it is quite another. Liquid fuels like gasoline, diesel, kerosene, etc have far more energy density than any battery tech could provide. @aeread Carbon Monoxide is not a biproduct of this process, but rather a step in the process. It is used in water gas shift reaction to produce hydrocarbons. The CO is taken up in the process. “It’s important to note that while this machine seems like it would be useful for removing carbon dioxide from the atmosphere, burning the transportation fuel it creates would then produce more pollution and greenhouse gases.”

The problem remains that carbon monoxide is created, and that pollutant is worse then carbon dioxide. Also, how is the liquid fuel generated? That is not explained at all. I think this development is really important, but lots more work is required to push this into commercialization. The solar aspect of this is the selling point i guess, but not really important to the system at all. Energy from any source can be used.

I love this project, but not the use it is projected to have. Better to put it at the end of a biomass generator and keep sequestering CO2 from fossil plants.

Syngas is certainly not clean-burning." Granted - but at least this technology has the benefit of utilising the CO2 back into the fuel production and would appear to use low amounts of energy (or rather high amounts of free energy from the Sun) to do so, so it offers a number of benefits compared to other technologies. Plus the syngas can be converted to synthetic fuels using Fischer Tropsch reactions that can then be utilised in exisiting infrastructures for running cars “It’s important to note that while this machine seems like it would be useful for removing carbon dioxide from the atmosphere, burning the transportation fuel it creates would then produce more pollution and greenhouse gases.
