A million barrels per day, for at least 2 years in a row.

This would be ecological disaster on a worldwide scale. We'd never be able to stop it, and the damage would by like an oil spill times a million. Just imagine a never ending supply of oil dumped into the world's oceans every year.

Energy Secretary-designate Chu has long been a champion of a project to engineer microbes that can make ethanol from the cell walls in corn stalks and leaves. This so-called cellulosic ethanol is widely expected to be a major improvement on the corn-based ethanol backed in recent years by the U.S. government. Chu and a number of other researchers are agreed that the production of corn-based ethanol is, on balance, a source of additional greenhouse gases. Engineered microbes may be able to make ethanol more efficiently. They might also make ethanol from other plant matter, such as prairie grasses, wood chips, or grass clippings. Even sewage might be a palatable feast for the microbes.
Craig Venter thinks these plant-to-microbe-to-fuel projects are the right advances to be making now. “These are smart guys, and I have great respect for them,” he says. But in the long term he doesn’t think these projects will be sustainable. “These are the first baby steps.”
Instead of waiting for plants to make hydrocarbons, Venter wants to cut out the middleman and head straight for their original source of carbon: the air. Researchers at Synthetic Genomics have been experimenting with
Venter
Craig Venter believes genetically engineered microbes can help wean the world off oil — and reduce greenhouse gases.
photosynthetic bacteria, which (like plants) use the energy in sunlight to combine water and carbon dioxide. Using some of the genes Venter’s team has discovered, the researchers have altered the bacteria. Now the microbes can rapidly build molecules known as lipids. Lipids come in a range of forms and serve many functions in cells, storing energy, for example, and forming membranes. But instead of using lipids for such purposes, Venter’s bacteria secrete them. Researchers at Synthetic Genomics have drawn up plans for gathering those lipids.
“They can go right into an existing refinery,” says Venter. Not only would these microbes not create any extra pressure to cultivate more land, but they would actually take greenhouse gases out of the air.
Greene is concerned that these microbes might cause harm if they escape into the environment. “I don’t have a Michael Crichton attitude that they’re going to destroy the world,” he says, “but we really need to understand them.”
Venter thinks Greene has a legitimate worry. “We should be totally aligned with the environmentalists on this,” he says. Researchers at Synthetic Genomics have been developing ways of addicting bacteria to certain nutrients they would not be able to find outside their tanks. If engineered bacteria escaped into a nearby pond, they would die.
But Greene wonders if genes could escape from the dying microbes and be passed on to other microbes in the environment. Genetically modified crops have also been engineered not to produce seeds to protect against contamination. “And yet we’ve seen that happen anyway,” Greene notes.
Synthetic Genomics is in the process of raising capital for a pilot plant. It’s not a great time to look for investors for any kind of biotechnology, especially one that’s still so young. And with gas prices less than half of what they were just a few months ago, it may be hard to get people to think about moving beyond oil.
“People have trouble seeing beyond the current week,” says Venter. But he warns that oil reserves will continue to dwindle and the Earth will continue to warm. Venter believes that synthetic biology must be part of the solution to both problems, because of its huge potential.
“It’s infinitely scalable,” says Venter. “We think the future will be very bright.”

This is what happens when sociology majors like Al Gore attempt to understand and predict science.
It is ignorant beyond belief to think that algae "will escape" and then contaminate the world with oil.
To the extent that algae can be engineered to excrete oil, it does it at its own expense - excreting gobs of complex molecules that take a huge amount of energy to produce is conta-survival.
If they ever got to the point where the algae was excreting light sweet crude, there would be zero worries that "escape" of the algae would be an issue.
Go back to Global warming or whatever you call it now - it's easier to pretend to understand climate science than it is genetic engineering.

QuantumSphere, Inc., a leading developer of advanced catalyst materials, high-performance electrode systems, and related process chemistries for portable power and clean-tech applications, today announced that it was awarded a research grant from the California Energy Commission to develop a process using nanocatalysts to convert biomass into biofuels.
The grant was awarded under the commission's Energy Innovations Small Grant program (EISG) and will fund the one-year development of an algae biogasification process that utilizes nanometals as catalysts for the purposes of turning vegetation and similar biomass materials into methane, hydrogen, or other synthetic gases that can be used for transportation and other energy needs. QuantumSphere will build a small-scale platform over the next 12 months to demonstrate the effectiveness of the process.
Algae-based bio fuels hold great promise due to their enormous energy potential. According to experts, algae grows 20 to 30 times faster than food crops, contains up to 30 times more fuel than equivalent amounts of other bio fuel sources, and can be grown almost anywhere. Studies show that algae can produce up to 60% of its biomass in the form of oil or carbohydrates. This oil can then be turned into biodiesel which could be sold for use in automobiles. The carbohydrates can be turned into alcohols, or gasified to bio gas, hydrogen, or methane, for many industrial applications.

What about predators? If these organisms are so different to their natural equivalents would they have any natural predators out there? How would that affect their survival chances.


petroleum. Algae biofuels have a negative eroei, thus more energy is required to grow the algae and process it than is contained in the resulting fuel.johhnytrash wrote:So what will the algae eat?

I would venture to guess that the energy required to run the grinder would be larger then the energy net in the wet oil fuel.
Algae oil has to use solar and wind power exclusivly to both grow the algae with all the pumping required and to harvest and refine the oil. Absent that it is a nogo just like corn ethanol. I don't see why this can't be done but they havn't done it yet and probably won't until oil gets above $200/bl.
