Powered only by natural sunlight, an array of nanotubes is able to convert a mixture of carbon dioxide and water vapour into natural gas at unprecedented rates. Such devices offer a new way to take carbon dioxide from the atmosphere and convert it into fuel or other chemicals to cut the effect of fossil fuel emissions on global climate, says Craig Grimes, from Pennsylvania State University, whose team came up with the device. Although other research groups have developed methods for converting carbon dioxide into organic compounds like methane, often using titanium-dioxide nanoparticles as catalysts, they have needed ultraviolet light to power the reactions. The researchers' breakthrough has been to develop a method that works with the wider range of visible frequencies within sunlight.

yeah i saw that one, but it looked different so I posted this. The other mentioned burning coal? Or was that another one? Either way, save the coal, use the sun instead!

The energy situation is entirely a manmade construct, there is no shortage of obtaining energy in a universe which, essentially, is matter made from energy. People need to think about the implications of this. Everything is energy.
If people want an abundance economy, which is technologically possible, then focus on the people who are shelving these inovations, or focus on making them for yourselves.
The more I read about this stuff the more I realise we should not wait for new energy inovations, we will have to build them ourselves, in our garages, from plans probably downloaded off the internet. Only then will these things reach a critical mass where the establishment won't be able to supress them.

Well if you're worried about that, then CO2 isn't really an issue. It's most of the other stuff that really fouls the air. Sulfurous emissions, particulate mater, nitrous oxides, unburnt fuel, carbon monoxide. CO2 is mainly an issue because of global warming, and because it dissolves in water to become carbonic acid, which may change the PH level of the ocean, which could lead to a massive die off of ocean life.
CO2 is odorless, tasteless, and generally isn't noticeable in the amounts you could plausibly find in the atmosphere. I mean, you breathe the stuff out. you're used to having it in your lungs.
