Rest In Peace, old friend, your work is finished.....If you want ON or OFF the DIESEL ”KnOcK” LIST just FReepmail me.....
This is a fairly HIGH VOLUME ping list on some days.....

SHELL is to become the first major oil company to produce diesel fuel from marine algae. Algae are a climate-friendly way to make fuel from carbon dioxide. They produce an oil that can readily be converted to diesel, and can be fed CO2 directly from smokestacks. Unlike biofuels such as corn, they don't use up soil or water that could otherwise be used to grow food, which can pump up food prices. The US government abandoned research on algal biofuel in the 1990s because of the low cost of crude oil. But as oil and food prices began to rise, small algal fuel producers sprang up. Shell plans to begin construction on a pilot plant in Hawaii immediately, which it expects will produce 15 times as much oil for a given area as other biofuel crops, thanks to the efficiency of algal photosynthesis.

Seriously, this is a positive trend towards sustainable renewable energy!!!
A good “symbiotic” way to deal with sewage and garbage, too.
Way off topic, but wasn't Soylent Green supposed to be marine algae before it was found to be made from people?
This is really great news! I wonder what their production costs are going to be. Hawaii’s a great place for a pilot too, since that means they save on trans-oceanic fuel shipping.
Interesting development. If power plants are forced to sequester CO2, why not put it to use and grow algae with it?

Good news for the Dutch.
But on second thought, even producing 15X as much bio fuel as we do today won't really make a dent in energy dependence.
And although the algae is grown from CO2, when algae diesel is compressed in a diesel engine with super heated 02, the byproduct is C02. So if you really want to reduce C02, shouldn't you just grow algae and leave it alone?
This is how to solve any problem—put a profit potential in the solution and let corporate America do it.
“A good “symbiotic” way to deal with sewage and garbage, too.”
Finally a technology to make our Congress into something useful.
Good idea. Build the power plant and the algae farm/refinery next to each other and pipe the CO2 to the farm: perpetual motion.
You can't just leave it alone. If left alone it will eventually die and rot, releasing CO2 back into the air. You have to hide it somewhere where it can't rot.
However, if you are using the biodiesel instead of petroleum you will take carbon dioxide out of the air and later put it in, instead of just putting it into the air from a millions years old store of it.
It's not perpetual motion. You need sunlight to add to the total energy supply to grow the algae. Now whether it would be better to increase the amount of usable energy by using solar cells or algae-diesel, I don't know.

Al Gore.... what is he going to make a living at now? All that c02 being used for fuel.. Don’t trees eat it? Lordy, we can’t to that and starve the poor trees.. Al, we need you to protect the trees.....
The only way to permanently sequester CO2 from the carbon cycle is to separate the carbon atom in each molecule from the oxygen atoms and process it into a non-oxidizing form such as diamond or fullerene.
Sounds good, but this statement needs to be revised: “Unlike biofuels such as corn, they [algae] don’t use up soil or water”.
Last time I checked algae required water to grow just like all other life forms on Earth.
