Probably completely impractical, but this conversation gave me a picture of people raising fast-growing plants in their homes/yards that they continually 'harvest'. This harvested matter than gets taken to a dump site and buried, capturing the carbon underground. I suppose the whole operation would have to either use solar power or be extremely efficient to avoid burning as much or more carbon based fuel than it buries.
