Algae Impact

Listen to "Algae Impact" and fill in the gaps.
tubes, liquids and colors fool (täuschen) you. What you're looking at is . But, instead of growing field crops like corn, , this farm has fields of tanks bubbling (brodeln) with algae. "People have been eating algae for centuries, and for very specific purposes, as a substitute (Ersatz) protein source. And then some cultures, because they taste good. We just simply haven't explored it. We haven't had to. We've that was further along technologically and stuff, so we haven't had to look for what are ."

Unlike , water and soil, these algae "bioreactors" require only , making it possible to place them in atypical (untypisch) growing locations like the . This 80-thousand gallon facility is on Arizona State University's Polytechnic Campus. thousands of strains (Gattung) of algae in hopes of creating new . "You can make just about everything out of the algae that you make from all other crop plants. From a standpoint of feedstock (Ausgangsmaterial), their than other types of crop plants that you can actually get more tonnage per acre than you can get from other crop plants."

So where some might see slime (Schleim) these scientists see solutions. "This is algae bio-mass. This is basically algae cells that have been taken out of the water that we grow them in." "Okay." "So we take the algae cells out of the water. They have been dried at this stage. And so that is the algo bio-mass, or the feedstock, that we're going to get from the algae." "Okay, so this would be to what?" "In this particular case we have , or what we call Arizona Crude (Rohöl) because it's . And this is basically crude oil that's been extracted from this bio-mass. Approximately forty to fifty percent of this bio-mass that you see here is oil or lipid (fettähnliche Stoff)." "So ? What's the rest?" "The rest basically is protein and carbohydrate (Kohlenhydrat) and minerals. And so, the protein and carbohydrate, once you take the oil out of that bio-mass, percent of what's left over. And this can be used as an animal feed, high protein, a carbohydrate, . It can also be fermented to produce ethanol."

Researchers say that one positive in algae production is . "In this section of the photo bio-reactors it's doubling . Theoretically one could pull half of the algae culture off every day and you'd have just as much at the end of the day as what you started with."

The challenge here is , but in creating a process that delivers food and / or fuel in a cost-effective (rentabel) manner. "Keep in mind that the algae represent a relatively new technology. While we’ve known they produce oil for a long time and maybe they were the source of the original petroleum ... it requires a whole to take it to a scale from the standpoint of competing with an industry that's a hundred years old."

Still . "We're making it more cost efficient every step in the process every day." And while you're in fuel production, you can always enjoy algae . "I have some algae cookies." "Cookies?! ?" "Of course I'm serious. …These are algae cookies that were made just for you. ." "That's like a butter cookie." ", an algae cookie." "From an algae expert."
