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.

Four years to recoup a capital investment is beyond fantastic. Even double that, as will be more likely when everything is figured in, is really good.

> thousands of times more than the negligible amount mankind has ever produced
nice try.
the yearly production of CO2 by humans is MUCH higher than the yearly CO2 production by volcanoes.
from first link I found :
-->volcanoes release a total of about 200M ton of CO2 annually.
-->global fossil fuel CO2 emissions (2003) = 26B ton CO2

The Key takeaway here is saving $15k a month on heating bills.

If the savings are representative or what can be achieved elsewhere, the economics and payback period work out, then it's a Win-Win.

The surest way to bring someone over to your Environmentalists side is to show people they can save lots of money. Haranguing them about the CO2 and driving up energy costs...not so much.
