Biotech Company Making Fossil Fuels With a 'Library' of Bacteria 386
Saysys sends an excerpt from a story at the Globe and Mail:
"In September, a privately held and highly secretive US biotech company named Joule Unlimited received a patent for 'a proprietary organism' – a genetically engineered cyanobacterium that produces liquid hydrocarbons: diesel fuel, jet fuel and gasoline. This breakthrough technology, the company says, will deliver renewable supplies of liquid fossil fuel almost anywhere on Earth, in essentially unlimited quantity and at an energy-cost equivalent of $30 (US) a barrel of crude oil. It will deliver, the company says, 'fossil fuels on demand.' ... Joule says it now has 'a library' of fossil-fuel organisms at work in its Massachusetts labs, each engineered to produce a different fuel. It has 'proven the process,' has produced ethanol (for example) at a rate equivalent to 10,000 US gallons an acre a year. It anticipates that this yield could hit 25,000 gallons an acre a year when scaled for commercial production, equivalent to roughly 800 barrels of crude an acre a year."

The Joule technology requires no "feedstock," no corn, no wood, no garbage, no algae. Aside from hungry, gene-altered micro-organisms, it requires only carbon dioxide and sunshine to manufacture crude. And water: whether fresh, brackish or salt.
How can anyone with a high school chemistry education take this bullshit seriously?
People with a high school biology education know that CO2 + H20 + Sunlight = Sugar, thanks to the magic of photosynthesis and the Calvin Cycle. Sugar + anaerobic respiration = Ethanol, thanks to the magic of anaerobic ethanol fermentation. You can argue that their bioreactors will need nutrient supplementation to maintain viability, and you'd be right. Those are not feedstocks however, as you only need small amounts relative to product. It's not bullshit, it's science.

because photovoltaic are only 10% efficient?
while I agree electric motors would be far better for personal transports, the problem is storage. You can't store electricity in great enough quantities for it to work well. Until you can get 400 miles fully loaded with less than 1 hour recharge time, on electric motors, they will just not work in the USA. Right now the Tesla roadster has the best range of ~350 miles . driving 25mph with only one very light person on board with no baggage.
The USA doesn't have the bus, or train infrastructure to support moving lots of people well. Trains roughly take 2-3 times the time it takes a car to go the same distance.

If you consider total consumption, not just imports, it would require around 15,000 square miles. However, the US has over half a million square miles of active cropland, and about 135,000 square miles just corn.
In other words, if you replaced ~3% of America's farming, or 12% of America's corn production with this type of hydrocarbon farming, you could replace all of America's oil consumption. Stick that in your corn pipe and smoke it, corn-based-ethanol producers.

How exactly would there be waste heat? The process magically circumvents the laws of energy preservation? No, the energy stored in the fuel is the energy taken from sunlight, just like the CO2 stored in it is the one taken from the atmosphere. The whole process is just a way to store solar energy in high concentration and have it usable at a convenient time.
