Biochemist Creates CO2-Eating Light That Runs On Algae

samzenpus posted more than 2 years ago | from the but-will-it-clean-my-desk? dept.

Biotech 121

An anonymous reader writes "Biochemist Pierre Calleja has a solution to reducing carbon emissions that doesn't require us to cut back on our use of carbon-producing devices. Calleja has developed a lighting system that requires no electricity for power. Instead it draws CO2 from the atmosphere and uses it to produce light as well as oxygen as a byproduct. The key ingredient to this eco-friendly light? Algae. Certain types of algae can feed off of organic carbon as well as sunlight, and in the process produce carbohydrate energy for themselves as well as oxygen as a waste product. Cajella's lamps consist of algae-filled water along with a light and battery system. During the day the algae produce energy from sunlight that is then stored in the batteries. Then at night the energy is used to power the light. However, as the algae can also produce energy from carbon, sunlight isn't required for the process to work. That means such lights can be placed where there is no natural light and the air will effectively be cleaned on a daily basis."

The algae produce carbohydrate energy for themselves as well as oxygen as a waste product.

Left out of the summary was the step where the carbohydrate gets converted to electricity and stored in batteries. Following the link in the summary to TFA, and then to the source, and even watching the video, I was still unable to find anything about this step.

The video showed that the Algae were in the outer cylinder of two concentric cylinders, and the inner won was apparently a light source of some kind.

I call bulls*it (5, Informative)

Anonymous Coward | more than 2 years ago | (#39910239)

Algae can produce energy via photosynthesis. Sure.

Claiming (as is heavily implied) the can extract energy somehow from CO2 sans sunlight is about as sound as claims you can run your car on hydrogen "extracted" from water.

Carbon isn't inherently a source of energy. Energy can be stored in carbon compounds by having carbon in certain oxidation states. Then in a redox reaction it gets oxidized to CO2. At that point, no more energy to extract. You need energy in at that point. Carbon isn't magic.

Thermodynamics. It's not just a good idea. It's the law.

Re:I call bulls*it (1)

Anonymous Coward | more than 2 years ago | (#39911101)

For algae (or any plant really) to live, the balance between photosynthesis (CO2 -> O2) and oxidation (respiration: O2 -> CO2) has to be positive

Plants work the same way as us (they need oxygen) the difference is that they have photosynthesis as well

Now see "Certain types of algae can feed off of organic carbon as well as sunlight"

It takes energy from both sources (unless they are kept in total darkness, which is not the case). Organic carbon in this context is: sugars.

So I don't see the issue. Energy input: light + sugars, output: light (and CO2)

The thing, as described in the text, violates the first law of thermodynamics.

carbon neutral electricity is easy to produce. It's been possible since the '70s, but hasn't been deployed because greenpeace types hate it.

Yup. It's annoying. The current generation of video producers are afflicted with the same behavior we saw in the early years of the web. Remember when people used the now infamous "blink" tag? Yah! It was a real treat to load a page with 20 blinking links. And this behavior was carried on with animated gifs. I remember opening pages that had lists with each list item bulleted with an animated gif; eg, a spinning ball or star, or a flashing diamond, etc. The next "craze" was to do all sorts of stuff with flash. I'm amazed how many sites are still doing all their nav in flash. The most recent bane to web design is jQuery. Take a look at the source of some pages once. It's astonishing just how many jQuery scripts are being used on some pages.

[begin rant] Well, now video producers are going through the same thing. It's cool to video the person talking, but they're looking somewhere else entirely. Or they zoom on the person's eye or hands or mouth while the person is talking. Real cool! I know that always stimulates my interest.[/sarcasm]

Now they're going absolutely freaking nuts using zooming in then out and back in, fast motion to slow back to fast, strobing, flashing, blurring, jerky images, a series of 30 images within 2 secs, etc. And NONE of the programs or ads using these effects contain ANY worthwhile information.

I was always amused by the Ford truck commercials and just how juvenile and primitive they were. All big, block letters sliding around the screen. Brilliant! I swear a person has to be functioning full-time with their lizard brain to respond to a commercial like that.

If I should happen to meet one of these video producers, I just might club him/her senseless. Then ask, "How's THAT for a special effect?"[/end rant]

It might be made up of interesting stuff for plants, but it is exceptionally sparse. At surface level (even at the lowest point) it is a mere 0.1675 psi where earth has a sea level pressure of around 14.69 psi. This leads plants to do some funny things. NASA has been experimenting with plants and low pressures for a while now but it isn't going all that well - the plants think there is a drought [nasa.gov] when the low pressure basically sucks all the moisture from them - even if they are hydrated very well.

malakai (136531) | more than 2 years ago | (#39910287)

Apparently Geek.com has it's own problems with editors & science....

This article is completely incorrect.

The total equation for oxygenic photosynthesis is:
6CO2 + 12H2O + light C6H12O6 + 6O2 + 6H2O
Broken down, the equations are:
water + light -> chemical energy and gaseous oxygen (a waste product)

(Historically called the "light reactions" because they require light. Photosystem II drives this light capture.)

That chemical energy is then used to capture carbon dioxide to make carbohydrates or sugars:
chemical energy from photosynthesis + carbon dioxide -> carbohydrates

(Historically called the "dark reactions" because the two processes can be uncoupled. The enzyme Rubisco uses the chemical energy from photosynthesis to capture CO2, which goes on to make sugars, etc.)

The carbohydrates can then be used for cellular functions OR as an energy source by the mitochondria, just like we as people use sugar as energy.These algae (What kind are they? I can't even find Pierre Calleja's research page. All I get is mixotrophic algae, which could be any number of algae. I'm assuming that it is a eukaryote like Chlamydomonas, but it could be a prokaryote like Synechocystis.) do NOT use carbon dioxide as an energy source. By definition, a mixotrophic algae CAN use carbon as an energy source, but NOT in the form of CO2, it must be in the form of sugar, acetate, etc.Furthermore, these lamps are NOT powered by the algae themselves. These lamps are powered by electricity to give the algae light to grow. That light then gives the algae the energy to pull carbon dioxide from the atmosphere.

First there's absolutely no mention of the mechanisms that provide energy - photosynthesis is implied and requires light, as the summary says. Therefore, the whole system requires light.

Then, nobody cares to explain how exactly energy is stored in "batteries", much less how the light is powered. An electrical light is implied, so the storage is explained, but how is electricity produced? And why do they seemingly connect the system to a power supply?

Does anyone have an explanation for any of this, or is this just as real as cold fusion?

tgibbs (83782) | more than 2 years ago | (#39910333)

OK, the algae could use light and CO2 to synthesize reduced carbon compounds, which could then be oxidized in the dark to generate light. Basically, this is just a biological version of a solar lighting system. Sounds finicky to maintain, but maybe energy storage in algae could outperform conventional batteries. But the article implies that the lamp has a net consumption of CO2. That implies a net production of other organic compounds, because carbon atoms can't just vanish. So what happens to this carbon "waste." There article says this is just another kind of fuel. This is plausible, but how do you get the energy out of that fuel? The normal way to get energy out of reduced carbon compounds is to burn or otherwise oxidize them--in which case you end up with CO2 again (if you do it fully). So once again, it is hard to see how this process can lead to appreciable net carbon sequestration.

Does this make sense? (5, Insightful)

UPZ (947916) | more than 2 years ago | (#39910335)

TFA: "Instead [the system] draws CO2 from the atmosphere and uses it to produce light as well as oxygen as a byproduct."

Correct me if wrong, but the law of thermodynamics states that CO2 is in a lower energy state than carbohydrates + oxygen. So this system transforms a low energy product into a high energy product and releases light (even more energy) in the process?

Re:Does this make sense? (4, Interesting)

UPZ (947916) | more than 2 years ago | (#39910357)

The point is, if the article's assertions (as I understood) were to be true, then we have free energy:

1) Burn carbon + oxygen --> CO2 + light (we currently do this)
2) CO2 --> carbon/carbohydrates + oxygen + light (this is proposed by the new algae based system)
3) Rise and repeat ...... (unlimited free light = unlimited free energy)

Wouldn't matter even if it worked. the government will never allow any solution other than carbon taxes.

how do you get energy from CO2? (4, Informative)

Karmashock (2415832) | more than 2 years ago | (#39910775)

Isn't it thermodynamically impossible to do this without USING energy?

Plants take in CO2 and make oxygen all the time. But they use energy in the form of sunlight to do it. So if the plant can produce power in the dark without any light at all... How?

Magic plant? Put a plant in a dark place with all the CO2 it wants... see how happy it is... it will die. Of course, then fungus and mold will eat it in the dark but that's a different family of life.

This whole report sounds like pseudo-science. Not unlike those perpetual energy machines that cranks keep claiming to have invented in their garages with nothing more then some old soda cans and a dream.

Here's another question, you know that guy that claimed to have cracked Fusion and wants to sell municipal grade fusion reactors? Well... where is he now? Claiming sudden technical difficulties owing to the fact that like all these other guys he made it up.

I don't know if it's the inventor's fault in this case or just a stupid press. But this story doesn't add up.

If you had glowing fungi, then you could use supersensitive solar cells to draw energy from them and store it in batteries, but do fungi even suck up CO2? I think Hyroelectric power and wave energy as well as wind power will provide a good portion of green energy in the future.

I think fungi actually emit it.

Actually yes, I recall that mould gives off gas, that is why it smells.

I meant that mould does give off gases with an odour. CO2 could be a component of that.

That's probably the most insightful thing I've read so far (including the very moronic title and summary). CO2 is the final byproduct of any form of reduction mechanism because it's such a low energy state. It's why cars and fires spit it out, and we do too.

Plants can only create hydrocarbons back from CO2 by using an external energy source like sunlight, and I'm wagering it's pretty improbable to imagine that this magical algae has managed to violate the fundamental laws of physics and thermodynamics to create perpetual energy out of something that is completely spent energetically. Chances are the algae need some additional nutrient in the water as well as CO2 if they were to drive any additional mechanisms for energy production.

I run into this sort of thing all the time and I find it disturbing because I'm not a scientist or any kind of expert. I'm just a moderately well rounded American... both in mind in body (hey, those cheese burgers were delicious.) And it seems like all too often the press, politicians, etc are making mistakes I was taught to spot in high school. I mean, this isn't even a college level mistake. This is a basic rudimentary failure to understand a fairly simple concept.

Sorry to rant, but the one thing that annoys me the most is the failure to grasp that correlation is not causation. This happens all the time. Some stupid statistical "study" will come out that shows a given graph plot goes up or down at the same time as another variable. They always assume that variable A went up because variable B went up.

This lead to absurd conclusions such as "red wine improves health"... It doesn't. But moderate red wine consumption correlates with better physical health. Why? Mostly socioeconomic and cultural factors. Wealthier, more intelligent, better exercised, etc people tend to drink red wine where as poorer people with all sorts of demographic health problems tend to not drink red wine. So red wine in no way makes people healthy. You could feed the wine to the unhealthy people and you'd merely make them drunk or deny the wine to the healthy people and they'd likely show no health difference.

Yet time and again people that don't know how to read statistics conclude that correlation is causation. This is merely depressing in the average public who were given the opportunity to learn better in school. But it's totally unacceptable in the media, the government, or most unforgivably I've seen some scientists try to get away with this logic.

It all goes back to cargo cult science:
http://www.youtube.com/watch?v=yvfAtIJbatg [youtube.com]

Everyone values the concept of science more as an ideology or a symbol of status then as an actual intellectual discipline. And so they don't even notice when they wander off into lala land because for them it was never about accuracy or the basic curiosity about the universe. It was always about power, status, and social conformity.

Sorry for the rant... /rant.

What's to stop them from runaway population growth in the atmosphere. Night and day, knoshing on CO2 and making light all over the globe? In fact, why didn't they do exactly that eons ago? Maybe because what's describe is impossible.

I'm pretty sure that whoever wrote the headline "Biochemist Creates CO2-Eating Light That Runs On Algae" has never learned anything beyond high-school physics...

I honestly thought that this light was in some spectral or intensity regime, where a mechanism (which here is falsely advertised as eating) was discovered where light could chemically dissociate CO2 into more useful compounds, and that algae were the catalyst for this mechanism. A bit (lot) disappointing to read that it was a grotesquely overblown version of "we keep this organism alive with a waste product and it gives us something we want in return."

The headline is about as misleading as something like "Scientist discovers CO2-eating oxygen that runs on Tree!" Except that Oxygen has absolutely nothing to do with the verb placed before it, and is actually a byproduct of the reaction.

Don't Think Of It As A Solution to Global Warming (1)

rally2xs (1093023) | more than 2 years ago | (#39913021)

Because it does not involve the rape of the free world's economies, which is the real objective of the global warming alarmists. This would be "geoengineering" which has been consistently rejected by these environmental extremists/fraudsters. Sooo... its not really worth reading, is it, since its Dead on Arrival.
