We are living in an age of unprecedented wealth, with millions entering the middle class every year. Homo sapiens live longer lifespans than ever before, with better nutrition, and better medicine than ever in our history. This is also the most peaceful time in our history, with record lows in crime and wars. The developing world is surging in wealth and in the west we have more opportunity and access to information than ever.

The air passes over a special filter that uses a base to attract and trap carbon dioxide, which is mildly acidic. Once the filter is fully saturated with CO2, the unit heats the filter to about 100 degrees Celsius (212 degrees Fahrenheit) to release the gas.

I wish they went into more detail on the chemistry of the filter.
