My Car Runs on Pond Scum!
Plenty of people have heard about the advances in finding green fuels, like getting fuel from soybeans or corn, but now research is continuing on the implementation of certain types of algae (pond scum) as an alternative fuel source.
Fifty percent of the weight of algae is oil, and they are incredibly fast growing (which can sometimes cause environmental problems.) This is why, according to an CNN article, Glen Kertz, president and CEO of Valcent Products, says he can produce about 100,000 gallons of algae oil a year per acre, compared to about 30 gallons per acre from corn; 50 gallons from soybeans.
He has created a new system for growing and experimenting with algae. Instead of using ponds to cultivate his algae, he has gone vertical with his growth plans with a system called Vertigro. The idea of using algae as an alternative fuel is not new, but this patented system allows a greater area of algae cells to be exposed to sunlight for photosynthesis.
This is a lot better than cultivating algae in ponds. Long rotating rows of contained plastic bags containing algae may make the Vertigro system the key to a competitive algae biofuel.
Apparently out of 65,000 identified species of algae, some types of algae could produce fuel best for jet fuel, and another may be better for truck diesel.
So be on the lookout for algae fuel coming your way.

I have a bunch of relatives that grow corn out in Nebraska. So I feel sorry for the soybean farmers that’re going to be losing business. But the price of soybeans, corn, and other grains has spiked the last few years, in part due to biofuel demands. And really expensive food isn’t good. So perhaps biofuel that doesn’t put a strain on our food supply would be beneficial.
Because of the way algae is converted to fuel (taking the oil directly from the plant for biodiesel, as opposed to corn, which is converted to ethanol (alcohol) by yeast), algae could only be used as a substitute for fuels in the diesel/kerosene/Jet Fuel family. Gasoline can’t be replaced by biodiesel.. So your car and my 2-seat airplane won’t be running on algae anytime soon. But Richard Branson recently had Virgin Atlantic fly a 747 with a 20% biofuel mix (without passengers). If airliners could start using biofuels? HUGE market for that algae…

One of the nice things about biodiesel is that it doesn’t have the negative affects on your engine that ethanol does. Ethanol tends to eat through rubber fuel lines and aluminum fuel tanks, and leaves gunky deposits in the engine.
And yes, if you’ve been reading along carefully, I did just say that alcohol can eat through rubber and aluminum. But pond scum won’t.
