New Heating Technology Uses Seawater and Carbon Dioxide (csmonitor.com)

Kenneth Stephen writes: While some enterprises have used sea-water for cooling, others are starting to use this for heating. and thereby cut back greatly on the carbon footprint of large facilities. What makes this technique even more fascinating is that a key component of this technology is carbon dioxide — the greenhouse gas that has climate watchers so worried. An Alaska aquarium recently announced "the first installation of CO2 refrigerant heat pumps to replace oil or electrical boilers in a conventional heating system in the United States" after 7 years of development, and predicts they'll now save up to $15,000 each month on their heating bill.

Carbon dioxide is a trace gas in the atmosphere. If too much of this is done, we'll run out of carbon dioxide. That will kill plants and make the Earth a very cold place. This seems like a bad idea to me.
