Couldn't those 8 scientists manage to grow enough veggies or herbs or something to both capture CO2 and feed the scientists?

Burning a gallon of diesel emits 25 pounds of CO2; so burning 88 gallons of diesel will emit a ton of CO2. 88 gallons = 1.6 barrels. $25/ton times 1/88 tons = $0.29/gallon. If the social cost of CO2 is greater than the $25/ton cost to capture CO2 to fill enhanced geothermal system, then it might make sense to subsidize the transition from petroleum to having our too big to fail oil firms mass produce algal bio-diesel. Maybe we could swap some algal bio-diesel for them to test market for enough tar sands deposits to make an equal amount of regular diesel. Keep repeating until cost to make algal bio-diesel is down cost to make petroleum diesel. Then expect oil firms to start investing in their own Algae Systems algal bio-diesel production modules.

With our too big to fail oil firms scraping the bottom of the barrel with tar sands oil, we really need to replace petroleum with already carbon-negative algal bio-diesel that US Navy and Algae Systems expect to get cost-competitive with petroleum in 2016 at about $10/gallon. We also need to clean up past emissions of CO2. Global Thermostat can capture CO2 for $25/ton of CO2 = $91.67/ton of carbon, which seems to be more than the price of carbon in coal but less than the price of carbon in natural gas. Enhanced geothermal system is good place to store CO2, using it as fracking/hydraulic/heat-transfer fluid. It would cost an average of $1.625 trillion a year for 100 years to capture enough CO2 for one 150MW enhanced geothermal system. That is almost 10% of US GDP. Over that 100 years it would capture about 6.5 trillion tons of the 36.67 trillion tons of CO2 that we need to capture. I suspect bio-char byproduct of algal bio-diesel contains about the same amount of carbon as the bio-diesel. So how much help algal bio-diesel is in cleaning up past mess depends on how much share of the total energy market bio-diesel as a substitute for petroleum manages to hold after the almost doubling of price of oil til bio-diesel is cost-competitive with petroleum.
Yeah for Rutland and its solar power programs. They should be able to sell any surplus power wholesale to electric utilities elsewhere.

Since too big to fail firms very much including fossil fuel firms own the USA, any national settlement very much needs to include the purchase of fossil fuel as reserves. Since they own the place, they MUST get theirs.

@gamoen I tried it this morning. Now it works.

@Paul Lauenstein I doubt very much that it is possible to repeal Citizen's United. What I want is: phase in an excise tax on all energy limited to a 10% increase in retail price each year until it gets high enough to cover buying both fossil fuel as reserves and renewable energy equipment including storage and smart grid electronics needed to integrate wind and solar into the grid. Buying fossil fuel as reserves is both necessary because fossil fuel CEOs have more political power than politicians do and only fair because when government wants land to erect a public building like a school, it has to exercise its right of eminent domain to buy land at a "fair" price. Buying equipment and having utilities use it is necessary because given half a chance utilities would want to deposit the money in an interest bearing escrow account and sit on it there as long as possible. Forcing utilities to spend the money on renewable energy and/or efficiency the same year they collect it gives their rate payers some benefit from the money as better electric service and/or cleaner air.
Discover magazine in May 2003 and again in July 2004 featured an invention--much resembling a mini oil refinery for converting all sorts of organic waste material (including plastic) to something resembling crude oil plus other energy products. I suspect there is one in that North Pacific Gyre already--but the plastic is still gaining on it.

@TimUpham @Phyl12 It is not growing rice in and of itself that is a problem, so much as using flood irrigation of rice fields to control weeds. Using flood irrigation once to get the baby rice plants off to a good wet start makes sense, but most of the growing season, it should be possible to hoe weeds instead of drowning them.

U S Navy has contracted since about 2006 with Algae Systems for engineering R&D to bring their now already CARBON_NEGATIVE bio-diesel from algae down in price to make it cost-competitive with petroleum. I believe they have every intention of licensing the technology to all the too big to fail American oil firms as soon as the cost of bi0-diesel comes down enough and/or the cost of petroleum toes up enough for the two prices to meet in the middle. Once this becomes a commercial product, it will be a big help in controlling the greenhouse gas content of both the atmosphere and the ocean.
The ocean's biggest problem seems to be CO2, the same as for the atmosphere. We really need to switch from fossil fuel to renewable energy. Buying most of the otherwise obsolete fossil fuel as reserves to keep them from being burned most likely needs to be part of the deal, given the enormous political power of the fossil fuel firms.
