@[email protected] Anyone who has removed a leaky AA battery knows what this process involves: KOH in battery electrolyte reacting with CO2 in the air to produce K2CO3; the white chalky substance we see at leaky end. For Equatics process to be economical we have to price carbon. In terms of my renewable carbon amplification model this one is probably very high ( no numbers in paper). To bad Ontario has only one northern sea coast.
