Every re-breather I have seen works on the basis of CO2 absorption using a product called ‘sofnalime’, which I believe is a trade name for soda lime. With each breath, the air passes through a cylinder containing the sofnalime, during which time the CO2 is absorbed into the sofnalime medium, and breathable air comes out the other end – simple and effective. So here is my query: Would it not be possible to scale this process up to pump air through a large amount of sofnalime to absorb some of the CO2 from our atmosphere?<br><br> <br><br>I am unfamiliar with the manufacture of sofnalime and the disposal of the used material (mine goes in the bin), so this may make the process prohibitive – I also am unaware as to whether anyone else has considered this notion.<br><br> <br><br>Thank you for reading this.Anonymousnoreply@blogger.com
