What is bad in it? Coverting water into a convenient fuel using the biggest culprit of global warming is none other than a achievement.

Using sun light to convert CO2 into CO will only help to make use of converted CO into some useful products as compared to CO2 as CO is more reactive than CO2 but ultimately the process except making use of so called free solar energy (though presently no body knowns authentically whether solar energy is free or not, as energy can neither be created nor destroyed)there is no other advantage being associated with the process. Plants are doing the same thing in a more environmental friendly way to convert CO2 into useful end products making use of solar light so there is to understand their (plants) importance in the nature and we should try to plant them and save them.

Why use genetic engineering – bamboo grows perfectly well as it is.

What would be perfect if anybody could figure out a way to do it – using CO2 to turn it into carbon, preferably useful stuff like carbon nanotubes, single molecule carbon sheets and buckyballs for technological use…

What we need is a mix of both, trees that grow extremely quick like bamboo but with genetic engineering bamboo on steroids. then we harvest the wood and turn it into flooring or furniture thus extending the co2 holding capacity for hundreds of years while we grow more of the crop to repeat the cycle. As long as it is not left to rot it will hold the co2. trees are neutral the give off what the took in all those years when the decay or burn. we can even sink them in the ocean to petrify them. just a thought.

Hmmmm

who would have thought that trees could have been the key to solving all of our problems. makes me think someone designed it that way.

Now that’s a novel idea Cal!

Yes, let’s plant some trees.

They have a long lifetime and they work through all those years to convert CO2 into Carbon (used in the structure of wood and leaves) and Oxygen which we can breathe. All the trees need to do this is sunlight, water and some minerals from the earth, all of them free and plentiful.

How about discovering organisms that change CO2 into something less nocive than CO…something like say…Oxygen? Oh, Oh! I know! How about every plant on earth? Instead of getting fancy with genetically-engineered microorganisms why don’t we do some gardening? Plant some trees maybe?

Use the sun and this complicated invention to convert CO2 to CO, then burn the CO to make heat and CO2. Or, alternatively, just use the sun to make heat. As far as CO2 is concerned, both ways work out the same.

Unless you want CO for some other process. As the article said, it can be used, via more expensive processes, to create liquid fuel. That sounds like the hard way to earn a living, but there are syntheses which use CO. Industry generates lots of it each year to help make other chemicals. So, as a source of CO, I suppose this one is the greenest.

Agreeing with Sepp i have to say from what i know co is more effective as a green house than Co2, so how is it possible that this could solve the problem

even if they produce bio fuels after that it will still turn into further co2 emissions wouldn’t it?

Carbon monoxide has a low energy density and is far more toxic than current fuels. Still, direct solar energy is hard to beat, and the carbon footprint is near zero if you’re capturing the CO2 from the atmosphere.

“We all are familiar with the effects of carbon dioxide on our environment. Carbon dioxide is responsible for causing the greenhouse effect.”

Everybody knows … except it may not be true!
