Kentucky Power plant uses algae to eat CO2 emissions


BURLINGTON, Ky. (AP) -- A Boone County power station is using algae to eat the carbon dioxide emissions from its smoke stacks.

The procedure begins with a line connected to the flue gas stack atop Duke Energy's East Bend Station. The flue gas is pumped into a feed tank where it feeds algae bubbling away in 8-foot tall tubes.

The algae consumes about half of the carbon dioxide in the flue gas. It has to be harvested periodically. Researchers say potential uses for the algae include feedstock, fertilizer and biofuel.

help me here

today I saw a blurb about navy using nuclear energy to convert seawater into fuel. Neutral footprint ... except for the extra heat of course.

But here, they are actually taking co2 out of the smoke stack to convert it to cattle food ... then it becomes methane.

I love planned progress.

I'll take my Liberty, it's not yours to give.

To be clear, a nuclear sub uses heat put out by fusion of

radioactive materials to heat seawater in a steam turbine which turns a generator which charges large batteries.

The algae produced from CO2 released from coal power plants (with some nutrients added) can be composted into fertilizer, fed back to livestock (it's delicious - think spirulina shakes) or, most exciting and most difficult, extracting the naturally occurring oils from the algae and making biodiesel.

The fuel from seawater

example was simply that the video suggested that it was a neutral footprint as to global warming but they ignored the extra fission and heat energy necessary to drive the chemical reactions.

As to the algae, the amount of methane the cows would generate is probably miniscule, but it's somewhat ironic that methane traps 20 times more solar radiation than co2 and the algae traps more solar energy in making the sugar.

No matter what you plan to fix, systems always push back.

feel free to trap my sugar any time.

As to your point I humbly disagree.

It was a sweet article

But just checking for cavities. Thanks for sharing it.

The author's bio page won't click through on Amazon...

it cuts off right after mentioning the author's appearance in Utne Reader, Mother Jones, and The Onion.

Anyhoo, glad to see the guy is actually a businessman and not some pie in the sky wishful thinker social planner type running around saying people should feel and do this or that.

The cynic in me says that the majority of times companies make (real) environmentally-friendly decisions it is because it is a cost saving measure which allows enough money to promote the move to the public.

Uncynically, where the author suggests that it will take a global shift in consciousness he is right. I would just say that for many people this shift will come not as a spiritual awakening but rather a change in fashion. As Robert Frost said, "Most of the change we think we see in life is due to truths being in and out of favor." Not that there's anything wrong with that.

Where's the LOVE?

This is the only product out there

that can beat Industrial Hemp in terms of efficiency.

Are you investing in AlgaeTech yourself, Chris?

I learned everything there is to know and then quit.

The entire biofuel industry decided to eat itself so I took some time off to wait and see who survived.
