Bromeliads and many succulents absorb CO2 and release O2 at night using CAM photosynthesis. They're tricky plants, opening their pores only at night to prevent water loss. The actual conversion is done during the day (in the light) using a sort of batch-mode conversion.
I suggest caution when surmising what millions of years of evolution can't do : )
Damn - great to learn, thanks! Though my point still stands, even with the CAM cycle, CO2 is converted to O2 during the day, they CAM plants just absorb CO2 at night... also it seems the CAM cycle produces much less O2 (obviously absorbing much less CO2 in the process) than other photosynthesis cycles...
