In Geoengineering : The Acid Test he reminds us of The Branson/Gore Equations (find a way to offset Virgin Air's emissions before the EU starts requiring airlines to buy emission allowances; win yourself $25 Mil.):
Harvard's wily Center For The Environment has upstaged its geoengineering competitors in the race for the $25,000,000 CO2 reduction X-Prize offered inventors by Al Gore & Richard Branson of Virgin Airlines.
Warning: Before reading any further you should know that Mr. Seitz is a polymath, with autodidactic tendencies.
..."Engineering feasibility" and economic practicality are quite different mattters
...The authors estimate it will take roughly 10 to 40 thousand watt-seconds of power to harmlessly transfer a gram of carbon from the atmosphere to the ocean.
In other words, a watt of electrical power devoted to the Zenz idea could hopefully remove about two kilograms (~4.4 pounds) of carbon a year . Since mankind presently burns about a ton of carbon per capita annually, keeping pace with the present growth of CO2 by leaching rocks with electrochemical HCl would require on the order of 500 watts times six and a half billion people's worth of dedicated electrical capacity. That is to say around 3 trillion watts.
As Californians know, a spare trillion watts is not always easy to come by- it equals a thousand nuclear plants or coal burning thermal power stations. At a dime per kilowatt hour ( given current fuel prices, allowance for inflation may be prudent), that's roughly a quarter trillion dollar monthly power bill , which would make the cost of offsetting all the carbon added to the atmosphere around a dollar a day per capita
Ah hell, I can't do justice to his thinking with cut and paste. Here's the link.
